trapped in a refugee cam outside of damascus as i.s.i.l. fighters cane ground. we talk about issues affecting this fragile planet like fracking. >> we shall employ all means at our disposal to bring the perpetrators to justice. we are in active pursuit of the mastermind of the attack and placed the reward for the information leading to his capture. we begin with a promise from kenya's leader who says he'll employ tough measures to bring to justice the gunmen that killed 50 students. al-shabab is threatening to wage a long war against kenyans. the group released a statement saying it will make kenyan

cities red with blood. the fighters valued to continue the attack until kenya's army is pulled out. five have been arrested. the president of kenya declared three days of national mourning for the victim. the bodies of many have been taken to nairobi, where grieving family members gathered. the incident children - the killers should have killed grown-ups, not children. >> theanother survivor of the attack feared dead was found at the university. kath iran sawyer has more. >> anunbelievable moment. a survivor rescued. many describe it as a miracle. two days ago, she hid on a wardrobe and covered herself with anything she could find.

she heard the gunmen shouting taunting victims, shooting. at one point they came into her hostile and took two of her friends. she's happy to be alive. >> there was shooting everywhere, i continued to hide. when i got hungry i ate body lotion that was there. >> forensic investigators, including u.s. personal had been at the university. those inside talk of a violent and bloody end to those that died. the government was keen to show journalists and others. the pictures are too gruesome for us to show. >> the government decided to display the bodies to prove to kenyans that the gunmen have been killed and to try to build public confidence in the security forces. police say they have made some arrests. >> there's a number of arrests that have been done today.

we have arrested another three, and i think the total number can reach about five. we will confirm that when we cabinet more detail. -- when we get more detail. >> there are areas that have been attacked before. there's reports about an attack on a university in the country. all the weapons they are using. it's not sold in garissa. these people must have passed several barriers controlled by others. so there was a security lapse. >> reporter: al-shabab fighters released a statement washing of more attacks. people are afraid turning to the war in yemen. the international red cross sends out a plea for a 24 hours

ceasefire. they are standing by ready to move medicines. russia is asking for a pause to allow fighters to leave. united nations held an americaning si session. -- emergency session much the red cross's time is running out. >> we have not yet been able to get in the medical supplies that we need to distribute them for the hospitals and the ministry of health so that they reach all the health clinics, and those that need it. they on 1 april, 4-5 minutes in sanaa. we have not been able to receive the medical supplies. we are negotiating and talking to those concerned and hope that it happens. at this stage, no we do not receive it yet. the united nations says more than 500 have been killed over

the past two weeks, including 90 children. tens of thousands have been displaced because of the war. >> the call for a ceasefire comes after a deadly air strike. bombs fell in the village near sanaa. a family of nine was killed in the attack. we have more. >> reporter: explosions lit the sky of sanaa, as the saudi-led strikes resumed. the tarts included a military base and other locations controlled by the houthi rebels and troops under the control of ali abdullah saleh on the mountains. >> translation: we continue to give logistical resistance to popular resistance in aiden and other forces loyal to the authority. we can say a situation is relatively calm. >> reporter: but as fighting conditions around the city of aden in the south, the number of

civilian casualties rises. hundreds have been killed or wounded. thousands are caught in the crossfire, in parts of aden most foreign nationals are unable to live the country. saudi arabia said it has set up a committee within the ministry of defense for coordination of countries wishing to send aid or evacuate nationals from yemen. the international red cross called for a humanitarian truce for that purpose. russia proposed a number of measures in the united nations security council. first, a demand that the u.n. is given rapid, safe is unhindered access to ensure people in need are released. and to allow countries and international organizations to evacuate citizens from yemen. there were meetings on saturday night to discuss the russian proposal and another by the g.c.c. members, aiming at a

political solution. >> we should not forget the root causes and conditions leading to the counter situation, and humanitarian situation in yemen is due to the failure of the implementation of resolution 2201 by the houthis. there was no lull in the fighting across yemen. the houthis managed to retake positions they lost earlier. they fried i'm mates -- freedom inmates. all signs on the ground that a military solution to the conflict is still far from certain i.s.i.l. has taken control of the yarmouk refugee camp outside damascus. it is full of palestinian

refugees. i.s.i.l. joined with fighters from the al nusra front to take the camp. al nusra front is affiliated with al qaeda. a video released showed members destroying artefacts in an ancient city. the video showed fighters using sledge hammers to statues. it was a u.n.e.s.c.o. heritage site. i.s.i.l. destroyed a number of sites and artefacts at the museum in mosul. the battle of tikrit appears to be winding down but there are reports of violence. authorities are assessing the damage. hundreds of homes have fallen victim to the war. caroline malone has the story. i.s.i.l. may have been pushed out of tikrit but there's evidence of violence on the streets. this is a neighbourhood where he witnessed shia militia burping buildings. the p.m. said the military would

rescue people. militia have no resume. the militia carry arms beyond the authority, and it is unanticipatable to us. the groups operating under the popular mobilization militia, were fighting alongside the army they backed the prime minister and the u.s. there are reports that the militia men found ways to fight i.s.i.l. in the city. the head of i.s.i.l. said it wasn't their men. >> we reg slogans and banners -- reject slogans and banners. they are ipp fill traitors. criminal collaborators against iraq and the social fabric. we cannot give them the chance.

people graffitiing the wall are no less a threat to us. >> reporter: i.s.i.l. is looting buildings in other parts of iraq. this is a building a 2,000-year-old city the capital of the first arab kingdom. it may not make it through this. iraqis have been scrambling to save parts of their culture. this man helps to take the manuscript from a province where i.s.i.l. fighters were approaching. we'll keep them here until the crisis is over. >> the archbishop says the books are more than financially val ub he uses them to teach the language that they are written in. in tikrit people are focus the on the damage in the city. after months of occupation and fighting and looting. >> president obama is pressing

congress for support of the iran nuclear deal. the president took his case to the american people. >> this is a long-term, with strict limits on iran's programme for more than a decade. unprecedented transparency lasting 20 years or more. as a member of the nuclear nonproliferation treaty iran will never be permitted to develop a nuclear weapon. iran's president hassan rouhani has to convince others of the way forward. he will meet with the supreme leader. earlier we spoke to lacy about why the weapons was so significant. >> one of the most important aspects was verification and transparency. it puts in place trance

personsry allowing the -- transparency allowing the u.s. to verify that iran has not made a move towards nuclear weapons. it's important. they will not just remain in indefinitely. it is important. we hear affects say we don't trust iran. that's exactly, if you don't trust iran that's why you need a deal. the only way to get the inspections is with a deal. we see that there is a lot of work ahead. it can't be discounted how much has been achieved. this framework agreement goes further than i think most technical analysts expected it to. so really they have crossed the major hump and have to take it to the finish line healy warned presidents hassan rouhani and president obama that they have to convince sceptics in the their governments that the deal is a good one for the first time in more

than a year fidel castro appeared in public. these images showed the former president greeding a delegation. he seemed healthy and full of vitality. he left in 2006 for health reasons. fidel last appeared in public in january of last year. since then the u.s. and cuba agreed to normalize relations. for the first time since the agreement. president barack obama and jacky rowland will come face to face. the state department says no meeting is planned. but the two will have an interaction. the president will be at a summit. >> for more on the issue to be raised at the summit and the u.s. agenda we ask you to join us tomorrow for "the week ahead". in indiana, jason collins, the first openly gay basketball

player says he's proud for the n ba and the indiana area to imposing the new laws. >> athletes coachers sponsors across the country took a stand on the right side of the history in a great time of need. >> protests continued in indiana, where the final four championship is under way. and the indiana pizzaria that said they would not cater a gay wedding closed. they received many threats. $847,000 was raised in a crowd fundraising campaign. >> ice-cream manufacturer blue bell is halting manufacture after a listeria concerns. patients at a kansas hospital

contracted the disease from the ice-cream. climate change threatening a nuclear power plant 30 miles from downtown miami. >> all this will go under water, and sooner than people thing. >> in tonight "a deeper look", why some say rising sea levels could turn this plant into the next fukushima.

from water to waste recycling, we look at our deeper planet. it's part of our series. there are many issues impacting the environment with 7 million sharing resources and gaelenting change. one -- affecting change. one place where it's happening is antarctica. the ice shelf is melting. science and technology correspondent jacob ward is

delling us why it's a concern. >> western antarctica is facing dwindling ice shelf. the speed is shown by colour red trains fast blue slowly green the slowest. it's not just the glaciers melting, and the places where they flow into the sea. they form ice solves floating extensions of the ice that hold back the glaciers. scientists determine that the ice shells have been melting 70% faster in the last decade than before. in the places denoted in red, the speed into the ocean is increasing every year. scientists say the smith glacier, one of the smallest is changing fastest, and it's a good way of understanding why the scientists are worried. not only is it melting, the bounding loin the place where

they rock well beneath the water is melting away and moving inland. here is what the bounding line looks like in 1996. check out what it looked like in 2011, five years later. it mooed 35km or 21 miles inland. this is the source of greater alarm. if you peel away the ice lair and look at the topography you see it's relatively flat there's no big mountain rangers to keep the ice flowing into the sea. subglacial is making it easier. this is true from the area which holds enough water to raise the ocean by 5 feet, in 100 years, the smallest selves could be melted. these are conservativive. >> joining us is daniel kay

many a professor of energy at berkeley. great to have you with so one of the major global challenges with a growing population is the question - how do we keep up with a growing energy demand? can you hear us mr cayman. >> yes, i can. >> how do we keep up with the growing demands, the growing energy demands? >> there's two paths that people are discussing. one is building more of what we have done in the past. building more coal-fired plants gas plants. we have to provide energy and address climate change. one of the most exciting areas is looking at the degree to which you can build out the infrastructure not just in the big cities but in the rural

areas, where 1.5 billion live without energy. that's where thu technologies bring solar energy. it's all coming together to give a new opportunity, a new waive of providing lots of energy but carbon free energy to people that didn't have access before. >> what is the challenge that climate change presented in terms of energy. >> well there's a range. what we are seeing is that climate change is directly affecting rural areas in terms of changed rain fall patterns fires, problems of water, people's cattle. and so we are seeing that even at the level of the smallest rural communities, climate change is stressing already poor communities significantly. >> do we have the technology this place to meet 100%. 75% of demands moving forward?

>> we have the technology in place, decreases in the cost of solar technologies the ability to use smart technologies to become the hub of little mini grids, house by house, village by village. the hardware is there. there hasn't been enough experiments and practical learning about how to do that. a few places are running ahead. we are seeing dramatic use of the new tech nolles. we are not keeping up with population growth or keeping up with the quite dramatically changing needs of people in rural areas, in urban slum, that are looking at a new range of products from cellphones to televisions, refrigerators. you bring up a good point. the global economy needs to be transformed. do you see it happening? >> i think it's going to. the question is is it going be

the counter actors the utilities we are used to or a new range of players, smart, new,.com type of companies that take advantage of new apps. it's like the taxi cabs versus uber. there are ways that the intelligence in your cell phone can provide enough opportunity so people can do off grid pay as you go taking home solar panels refrigerators, televisions and pay with mobile payments. or there's the utility model. if we don't build out the new opportunities, we'll have to fall back on the fossil fuel technology, it takes the climate change problem worse. >> stand by for a moment. according to the national oceanic attos feric association,

the major force assist the lose of land-based ice. water expands as it warms, it's a major problem. the major problem area is florida. more than 1,000 miles of coast are at the mercy of the sea. so is a major nuclei power plant. >> reporter: turkey point, florida's biggest power source was built on the edge of bisquay bay, with rising sea levels. the reactors sit 20 feet above sea level, but that is not reassureing to critics who calls turkey pointed a catastrophe waiting to happen. >> could be 60, 80, 100, but it's guaranteed the ocean is coming up. where they have the spent rods they were in a pact. that's the way it was in fukushima. >> after fukushima, the u.s. nuclear regulatory commission ordered the nuclear plants to resume safety plants.

in an email to al jazeera an nrc spokesman said turkey point is secure against counter conditions much the nrc reviewed the flooding re-evaluation:. >> peter harr lamb a geologist showed me the maps he made showing how rising seas will infiltrate florida. that's 6 inches. >> in the next 25 years. >> reporter: i look at this it looks like it's swamp. >> it's surrounded by water. the u.s. government predicts sea levels could rise 6.5 feet and

as it rises storm surges get bigger. in 1992 the area was devastated. andrew's peak surge missed the plant by 10 miles. >> fpl tell you or many in public that turkey point withstood the full brunt of hurricane andrew. winds and surge. it was never tested by the surge. >> if in florida light and nrc is right, south florida will be tested by bigger questions as the water rises. how soon? >> not this year. not 30 years. 200 years, i don't expect much of florida to be above the line. how do you depopulate an area like miami?

bringing in rob joins us from chicago, senior policy analyst for the water programme. great to have you with us. >> thank you for having me. >> when we look at the water levels areas that were flooded are places where people lived. how concerned are you that these areas, despite levies are at risk. >> if you look at florida, there's 145 billion worth of property that will be basically having water lapping at the foundations with 3 feet of sea level rise. that's a conservative effort as the earlier segment on antarctica glaciers indicating. we see the ice caps melting quickly than scoin tists understood. a lot of sea level protections don't factor in ice melt that is that fast. >> given the facts, how do you assess the global or national

response? >> nationally we made progress in the past knew months the obama administration took steps that are important. they are updating flood standards to use cove estimates for developing federally funded infrastructure projects. and f.e.m.a. will be requiring states for the first time ever to comply with disaster mitigation and disaster preparedness statues to examine climate impacts. they are important steps forward for getting states to assess and determine what steps are necessary to mitigate for future natural disasters, and the rising risk of disasters attributable to climate change. there's a lot we need to do. over the last 30 years we d more to move people into vulnerable areas, and climate change and sea level rise adds to the difficulties that the earlier actions have put on our country. >> we have seen the nation come

together to rebuild, to give donations after major floods and disaster. where do we stand on preventive measures? >> not very good. congress loves to shovel out buckets of money in the wake of a disaster to show it's being responsive. we spent $250 billion responding to flood disaster. we spend 5% to mitigate against flooding. we don't do a god job. a lot of policies and practice as at the local, state and federal level give more to keep people in vulnerable areas than to help people move to higher ground. >> what are the global projections. how concerned should we be moving forward? >> it's a big concern. the latest international panel on climate change projections.

actually it under estimates the problems of sea level rise. they anticipate a minimum of 2 feet rise factoring in perhaps more ambitious reductions in c ox 2 -- co2 emissions than we are liking to see. when you look at some of the emission scenarios, like the national climate assessment. we are probably going to accept something more like 3-4 feet of sea level. this causes a problem not just for the properties that now sees the oceans lapping at the foundations. the real problem comes when you have storms hurricanes tropical storms pushing a storm surge in on top of the sea level rise. that is ramping up the risks and damages that we experience in the future stand by. i know dr cayman is with us.

from too much water to not enough in california a crippling drought is in the fourth year. the governor issued restrictions to reduce water usage. it may be too little too late. a river that helps to water farms. jennifer london explains. >> reporter: on a late afternoon day this family is fishing for dinner along the river near fresno california. chances are they will not catch anything. the state's second largest and longest riff is dying, topping the list of the nation's most endangered rivers. to find out why i met with conservation expert john kain for a trip on the river. >> the most important reason that the river is in bad shape is it doesn't get enough water to be a healthy river. >> reporter: why is that?

>> so much water is diverted for agriculture. >> the californian central valley is home to the bread basket. crops here help to feed the world, farms making i'm acres of farm land. over the course of 366 mile run, the river and tribute air yeas are dammed 73 times. water syphoned helps to irriate harry's lemon orchard. are you the reason why the river is the most endangered. >> if you want to go back to when it was decided the water was to be diverted to go south to benefit more fit more people. and to go all over the world. that killed the river. >> every day people come to the river. what you can't see is there's no water and hasn't been for years.

if you look this way, this was the mighty river. at one time there was enough water to carry steam boats 80 miles up river to fresno. today there's just sapped shells and foot -- sand shells and footprints. parts of the river with water is so low the immigration of salman has been reduced to nothing. attempts to stock the river had mixed rul. >> those living and working here worry about a future tied to the san war keen. >> it would be detrimental to see the river deteriorate more that now. >> there's a lot of political forces that would rather have the water for farms, and not worry about the river. we are asking the state waterboard to stand up for the river and protect it. >> les is with the state waterboard.

the agency in charm of water rights in california. >> why hasn't more been done? >> everywhere wants these things to happen quickly. many people will not like these specific answers, but what we'll do in the process is make sure we are relying on the best science for the protection of fish and wildlife and balance it with the uses for agriculture. >> cop vervesists say increasing the flow a small amount can balance the needs. >> the river can be saved. the plan calls for 25% of the flow to stay in the river. >> that may be a hard sell during the drought which made a bad situation worse. then there's the drilling technique known as fracking.

the latest epy center is on the new york-peninsula border. it runs under the states. it is the biggest source of gas. new york's government banned fracking new yorkers can't tap into the source. up to s in four new york counties talked about seceding from the state to cash in on what is beneath them. >> reporter: here in new york spire houses are corn down. a sign of the town's slow death much the one thing people here believe can save it is right beneath them. >> we have two assets the skilled workforce, which has left and the other thing, under our feet is minor always. >> that is tim, the town supervisor. it sits on one of the largest

gas fields. residents say if they can drill into the land. it will bring coughlan back to life. there's a prab - new york state doesn't allow flaking. i got the -- fracking. i got the call to succeed. >> they are looking to leave the state of new york and join peninsula, where fracking is legal. >> if you look at the rest of the country, it's not right. the biggest resource is in the ground. >> reporter: new york government said the health costs for drilling for gas are too high. >> i don't want to choose between jobs and health. >> according to a study published by the national institutes of health. they use toxic and cancer causing chemicals and said: . >> but the author cautioned that the boom is so new that long

term studies have not been done. it's unlikely that the towns will secede from new york. in order to do that they'd need the approval of the federal government and the regs latures of both states. it's not impossible. so we went to see how the other half lives. we'll be down the middle of the draw units. doug has been a commissioner in peninsula for 12 years. >> we have around 1500 wells. fracking is a boom to the economy. >> what we have is no debt. we cut our taxes. farms are healthy. there's prosperity. prosperity for people like dick harris. his house is next door to a drill pad. >> all four of these wells go down a hill. right underneath my property. >> how has that changing your

life do you get royalties from it. >> yes. >> are you worried about your health? >> no. >> the long term health effects are uncertain. jim says as far as he's concerned fracking is worth it. >> we have it. let us take it out of the ground. joining us for a deeper look is daniel cayman a professor of number at the university of california and rob more an analyst with the national resources defense council. >> where do we go from here staying a step ahead of global environmental concerns. >> the starting ground is we need to understand the benefits of the different technology options wets have. debates over fracking large-scale solar on the water issues. all of these say we need to develop a counter currency to think about which products benefit. some use a price on carbon.

either say let's do a cradle to grave. places around the planet taking those steps, they get a common currency are finding ways to compare the pluses and minuses of different projects. that's a big step forward. >> how big of a role does politics play in environmental policy. >> on issues like climate change it's something you can't avoid. it's a political litmus test. you have governors, government rick scott in florida came under fire for denying the existence of climate change or at the very least what is alleged is that state agencies have been told not to use the words climate and change together to described the risks that florida faces. it's unfortunate that we allow politics to trump the facts to look after the future of our

families and our homes and communities. but it's bad - it's bad politics bad practice and policy all the way around. we'll continue the conversation as we look at a fragile planet. thank you both for your time on a deeper look. >> thank you. >> thank you next on al jazeera america - congress has low approval ratings, many can'ted dates are un -- candidates are unopposed come election time. what one man is doing to give voters a choice. how effective are e-cigarettes. it's claimed that they can help smokers kick the habit.

welcome back. this month plenty will toss their hat into the ring to run for president. when it comes to running for congress or senate not everyone runs a tough campaign.

dozens of incumbents ran for office unopposed around the country. michael shure explained how it inspired a brit a former advisor to david cameron to intervene. >> reporter: this is alabama senator jeff sessions in a bit for re-election last november he received 800,000 votes, while his campaign twitter had 12 tweets, his facebook four posts, and he had no opponents. amid unprecedent discontent. voters if they got to the polls didn't have a choice once they did. half of georgia's congressional delegation ran unoopposed. pore massachusetts, it was two-thirds. many names like john luize, charlie dent and joseph kennedy isn't it have a primary

opponent. enter crowd pack. >> every voter innery distribute should have a choice. it turns out in tern parts of america -- certain parts of america, last year they didn't have a choice. >> the problem is seen as big, yet fixable. what we want to go is give politics back to people give them a sense of control. >> to do this crowd pack started their unopposed project. raising money to field candidates in each distribute where there was one name on the ballot last time. >> the money will be distributed to the opponents of the unopposed members of congress who ran in 2014 let's make sure it doesn't happen in 2016. >> reporter: crowd pack invites donors to contribute any legal amount to fill some voids. it's conceded that the climate of money in politics is not about to change.

>> you have to start with the reality that money is sport, and political donations is the most effective way to make change happen. >> crowd pack is non-part stan but their point is the election takes two. >> for us it's a principle of democracy. it's not for us to judge whether a candidate is better or worse or a party is better or worse. our role is to help democracy work better. >> can it work or is it a waste of time or money to field an opponent. maybe we should ask representative eric cantor - former representative eric cantor. >> the los angeles area has the second-largest homeless population in the country, among them thousands of people with medical and mental health issues. a new apartment building is designed to supply housing and support that many need.

rob reynolds has more. >> reporter: it's not a mansion, but it's home. >> the bathroom is the biggest thing you miss. >> reporter: tj who asked we not use his last name was one of tens of thousands lying on the streets or in homeless shelters. >> i lived day by day. i couldn't thing of a plan to get better. i was too busy trying to get sleep for that day, and food for that day. now tj has a future and a new life for homeless people in downtown l axe. it's a new approach. residents not only get a space to call their own, but there's an on-site clinic for meg at health and addiction problems exercise art and education groups. >> people that live are tenants.

they have a key to the apartment. there's no time limits on showing they stay here that is up to them. we have built into the structure on side services mental health case management - whatever they need it's not cheap. it's a $40 million project funded by state, local and private sector. supported housing has been shown in the end to reduce costs to taxpayers. each chronically homeless person sues -- uses 75 to 100,000 a year. when people move into permanently supported house, hospital visits go down by 77%, which is huge. >> reporter: the less tangible benefits are just as large.

>> it's hard to put it into words. i feel normal again, i feel human. i feel capable of living life again. >> reporter: a new chance at life in a place called home. u.s. centers for disease control launched an anti-ad campaign for e-cigarettes. not everywhere lyings the government campaign. >> for 30 years shaun robinson used to mistake a pack of secrets a day. >> i was like wow, i quit smoking. i don't think my mum believes i have quit smoking. i smoked ta long. >> e-cigarettes have been touted an anti-smoking tool. users say it allows them to control and decrease nicotine

they are taking in. the u.s. centers for disease control insluds egrets in the anti-smoking campaign arguing the alternative is deadly. >> adults that think they'll get huff cigarettes by -- get off cigarettes by taking e-cigarettes found yes may have quit if they didn't use them. >> many that used egrets as a cessation tomb continued to smoke. it's feared that the fruity flavours will attract children who may not have otherwise started smoking. robinson disagrees with the arguments. convinced that egrets cap reduce nicotine depends. he opened a business dedicated to helping customers quit and invites clients to display the last pack of cigarettes. >> i'm in the business to get

people off cigarettes. the way i quit was with e-cigarettes. i'm proor that they do everybody good. despite u.s. government warnings and now advertisements to the contrary. star gazers got a chance to see the shortest lunar eclipse in the last century. the earth, sun and moon aligned perfectly. in the process the moon appeared to turn a red-arrange earning the blood moon label. it could be seen from the west coast all the way to australia. kevin corriveau joining. those on the west had a better shot. >> they did, and if you have seen the blood moon it's amazing, looking bigger than a normal full moon would. >> you have to get up early. >> across the united states look at the radar. we are looking at snow. and tomorrow is a huge holiday. we have snow across parts of michigan across the wisconsin,

as well as up here across the north. but as we go to the beginning of the week we are looking at moisture pushing into the south. that will fuel the weather we expected to see later in the week. as you see, across the south-east. we are looking at moisture pushing in. thunder storms are developing not too much on monday but as we go to tuesday, we have an influx and another system coming in. it will lift up the moisture making it unstable. that will continue tuesday, wednesday, thursday. look at this. on tuesday we expect to see a bit of rain across california and over the next 15-30 hours anywhere between 2-3 inches of rain. that will make a bit of a tent in what they have seen.

that's the weekend weather. weather.

mini slums in columbia lack infrastructure that can lead to dangerous streets at night. one down is using recycled plastic bottles to change that. >> reporter: in a dark alley, a glimmer of light. these plastic bottles are hoping the people walk home safely for the first time. they are cheap, bright easy to make. >> you need the solar panels, the l.e.d. and the battery. the controller how, when the sun goes down does the light turn on. we need a balance between a few

parts which the community can build and repair themselves. no more do you have to wait for thousands of parts. you can make it by hand. that is the breakthrough a circuit board that can be prepared and gives jobs to communities. in order to light up san francisco, 100 students from a nearby university were bussed in for the day to help. each light is composed of eight parts, cost $70 to build, and nothing to operate. san luis is a perfect recipient. many arrive said fleeing the internal conflict and found no basic services. >> translation: you can imagine the impact that you have on these people. that is the most speaking thing, to see the people smiling, they know the quality of life improved. they know having light in the

alley ways will improve the security. >> reporter: safety has been an issue with gangs operating in the neighbourhood. poorly lit areas turned into a magnet for crime, something the residents hope will change. >> before it was so dark i couldn't see anything. 100% better with the lights. >> it was never safe. if you saw movement up ahead, you'd choose a different route. now it looks beautiful. >> reporter: workers plan it in stall 2,000 lights. all told it's an effort to harness the sun's power to brighten the lives of entire communities. that is innovation. that will do it for us at this hour. i'll be back with another hour

of news at 11:00pm eastern. stay tuned. "america tonight" starts now. we leave you with a beautiful look at the empire state building. have a great night.
