we made the initial investments in the plants and the pipes. but once we accomplished that, there was this great recognition that we had a series of issues associated with wet weather conditions. storm events where, all of a sudden, you're dealing with a lot of water. narrator: large amounts of rainwater can cause flooding. engineers developed two approaches to stormwater infrastructure to transport water away from the urban environment. one approach was to carry waste and stormwater through the same pipe. this combined system was less expensive than building two individual pipe networks. and stormwater was seen as a way to flush out the sewers. through the 19th century, the combined system was considered state-of-the-art throughout the world, and is still in use in many cities today. but cities constructed these systems before treatment was the standard. and even today's largest treatment plant doesn't have the capacity to treat the sudden volumes of water rushing through a combined system during rain. the plant is overloaded, and the excess r

the plant is now under heavy guard. there are three checkpoints between the airport and the complex. and tanks have been deployed. these are the living quarters were many of the victims were taken hostage. we were only allowed access to the entrance. this build is a cafeteria. bullet holes serve as a grim reminder of the violence that gripped the complex over a four day period. the hostages were gathered up and brought to this place. the extremists strapped explosives to some of their bodies. the living quarters are about 3 kilometers from the gas plants. charred and destroyed vehicles line the route. preparations to restart operations at the natural gas facility are under way. officials say security has been tightened. the media tour was part of the algerian government's efforts to reassure the world that the complex is now safe. but the journalists were only shown a small part facility and were not allowed to go near the area where the workers lived. there's many questions unanswered. the visit served as a fresh remin

and the evergreen plant like the snake plant or this one is called a chinese evergreen.g about it is where a lot of people do fail with houseplants is that the care is pretty simple. pretty simple things. when you do get a new plant, if you start to see some of the lower leaves turn yellow, don't panic. what the plant is doing is acclimating to your new less than perfect environment. it's come from a greenhouse most of the time. give it time to acclimate. people will bring it home, put it where they want it, make sure it's getting enough light. >> do you want direct light snz. >> depends on the plant. this plant will be able to live in low light. all of these plants are very easy to grow. but you put this in that spot and starts to lose leaves. what a person is inclined to do is move the plant to another spot. or add more water. and what that's going to do, you don't want to over water the plant. you want to give the plant a couple weeks to acclimate. if you do have a saucer like this so you are not getting water all over, don't let the plant sit in that water for more t

than the normtal plant.g the plants to be move sugar available and you're genetically modifying microbes to use the sugar? >> exactly. what we really want is a plant that grows well and at the same time is able to release its sugars. when we want them released. >> is there an adeal plant from what you've learned so far? >> there's no one plant that's going to be the silver bullet. it will all depend on the climate and the location. so in the u.s. midwest, the plains states might have switchgrass. the pacific northwest might have trees. the very deep south could have sugar cane. it all depends on the climate, the amount of rain, sunshine, et cetera. >> let me guess where you're originally from, nebraska, cornstover. >> the interesting thing about cornstover we could have our food, the corn and use the rest of the crop for producing energy. >> right. >> it sounds like you're changing agriculture. >> we hope to change agriculture. when we got the grant, we said we're going to do fuels that could go in all modes

plus it's clean abundant and also a little dangerous but the risks may not stop one nuclear plant from powering up i had a look at how a company is jumpstarting its nuclear program and the chain reaction it could cause . and pushed to the limit because the u.s. military lacked the resources it needs to fight al qaeda in africa it looks like it's becoming more dependent on local african forces to do with dirty work i'll tell you why. it's tuesday january fifth february fifth excuse me four pm here in washington d.c. i'm liz wall and you're watching our t.v. we begin today taking a look at drone strikes targeting american citizens a confidential justice department memo just released reveals the legal justification for the government to conduct these strikes perhaps the most controversial part of the memo is that the government does not need evidence to justify a deadly attack here's a piece of what's now being called the white papers obtained by n.b.c. so it's quote the condition that an operational leader present an imminent threat of violent attack against the united states does not re

the plant's operators have a different view. they say cracks around the foot were caused by ground water. the experts say there's little evidence to support that view. >> translator: we don't have a thorough explanation from the utility. we'll have to listen to what they have to say. >> reporter: the regulators say they may need to check the structure of the plant and they may ask managers to review measures to protect the plant against earthquakes. those findings could keep the plant offline for some time to come. operators say they will conduct another additional survey of their own. >> translator: we would like to confirm through our geological research that there is no active fault under the plant. >> reporter: experts say the plant on the sea of japan coast may also be sitting atop active faults and they are looking at four other nuclear facilities. 48 of japan's 50 commercial reactors are still offline. the people who run the plants are working hard to prove they are safe but the latest findings suggest restarting some of

he also stays ahead of the game with new technology and planting and growing techniques as well. >> planting used to be a function of, um, of the university system. but as the university system struggles for money and they don't have the resources to do the breeding, private breeders now started to produce different varieties. and what we're looking for is, we're looking for all the great characteristics of seedlessness and easy to peel, high color, and sweet. but we're looking for time periods of the season so we can give the consumer a great piece of fruit from the very beginning of october all the way through april instead of just having a specific time where it's mature. >> and as mandarins continue to develop a reputation as a healthy, easy to eat, convenient food snack, more californians may realize that bigger isn't always better in the produce world. for "california country," i'm tracy sellers. >> hi, i'm adrienne garcia from marche in menlo park. today, we're gonna be making a honey panna cotta with clementines and candied zest. so, first, what you want to do is, you're gonna bri

what kind of work is going on now at the plant? >> at this point, the most important task is to cool down the reactor. if these units are kept consistently cool, if not, another meltdown could happen. they are also stored in old reactor buildings. the other important task is to remove them. workers already started at the number four unit. it houses the largest amount of spent fuel, and it's the easiest area for workers to access, which means this reactor didn't melt down. plans to start the removal process in november. once the spent fuel is removed it will be transferred to a pool built above ground. but the pool is not big now enough for all of the spent fuel. so there are plans to build a new facility that relies on titanium instead of water as a coolant. >> how long will it take to remove the fuel and dismantle the reactors? >> there are plans to remove all of the spent fuel by 2021. the next step, remove melted fuel from the reactors. the entire procedure will take until 2051. that is 40 years after the accident. >> what are t

since then environmental groups and neighbors have been trying to keep the crippled plant down it's aab experiment and were all the rats despite safety concerns here in santa know free nuclear energy could be a large part of america's energy future the obama administration has been an advocate for the technology even in the wake of the fukushima disaster the president secured an eight point three billion dollars loan guarantee for two nuclear reactors in georgia. we're going to have to build a new generation of safe clean nuclear power plants in america nationwide there are one hundred forty licensed reactors according to the nuclear regulatory commission nuclear plants generate twenty percent of the electricity in the u.s. we take the. reason we're doing research to be very serious the operators of santa know free presented a plan to restart their reactor at seventy percent so you know yes this is if you see. some neighbors are still scared former nuclear executive arnie gundersen believes the reactor steam generator is a disaster waiting to happen if those troops and fail well forge

those are the street trees we want people to be planting. we do a lot of tree plantings. all of you must intuitively go, "of course it's good to plant trees," of course, i want to put a rain barrel on my house." but is there a measurable environmental impact? trees are going to take up a lot of stormwater over time and are kind of a long-term green investment. we've had more than 200 volunteers come out planting street trees. we need people to make active changes on their property. and to reduce the amount of flow that's going into the combined sewer lines, we're trying to install 4,000 rain barrels. narrator: homeowners can disconnect roof gutter downspouts from the sewer system and divert the stormwater into a rain barrel. schombert: the rain water then can be used to water lawns and gardens and infiltrate back in the ground slowly, rather than being piped to a creek where it disappears moments after the storm's over. it's being held within the watershed and it helps regenerate ground water and stream flows. hecht: that's what we're going to do this afternoon is think a

, what to plant, when to plant it. i live about 1,000 miles up right now, so it's a little colder, and you have to realize, like, i can't plant tomatoes when they're planting tomatoes down here. it's just understanding the seasons and understanding when things want to grow and then they're gonna grow the best. >> students feel and i feel that by producing our own ingredients we can become better chefs. we'll get to learn a little bit about our food systems and how we interact with our food systems. we're in a unique position to do that. >> people come from all over the world, studying at the institute in the heart of the lush napa valley, getting an opportunity to learn how to grow, harvest, and market the produce. much of this early morning's harvest wi be sold at the local farmers' market. students run the greystone green thumb stand themselves, although they are supervised by professor chris loss. he's got a doctorate in food science and believes it's important for students to learn the relationship between the farm

[ticking] up next, a coal executive admits his power plants are hazards. >> how much coal does this plant? >> every day this plant burns roughly 19,000 tons of coal. that's two trainloads, and each train has about 100 cars. >> controlling carbon emissions in the near future is inevitable in your view. this is gonna happen. >> it's inevitable, in my judgment. >> you're one of the biggest polluters in the world when it comes to carbon emissions. >> we're one of the largest emitters, and it tells you how daunting the challenge is that we have in front of us. >> when 60 minutes on cnbc continues.

they want to build a geothermal power plant in the country's largest national park. officials were in hokkaido tuesday for talks with representatives of the lot government and hot springs association. the trading house executives have been studying the possibility of building a power plant in a national park. they hope to begin surveying the ground in june. they want to use electromagnetic waves to check the scale and location of the heat source. local council members would then study the impact of a power plant on the local environment and hot springs. it would be the first such survey in a japanese national park. the government last year eased regulations for developing parks. >>> innovators everywhere are battling to find ecofriendly power sources. this week, more than 125,000 professionals from 65 countries are showcasing their ideas in tokyo at the world's largest renewable energy expo. nhk world's rina nakano plugs us into this year's korean energy wins. >> reporter: solar, wind, fuel cell, there's plenty of power at tokyo's world smart energy week 2013. indust

as well as the pg&e plant. we were able to get the pg&e plant closed because of the illness in my community. i want you all to understand that we tried to work with the doctor about another location because we do have what we have a help node on 3rd street that came under the redevelopment agency where health projects are supposed to be located but for some reason they wanted that location. people moved out of that building because of the stench and the flooding there and when i saw the eir they tested a block and a half away, not where the building was. i think i mentioned to you before and i know you have the information in your packet about how the community bay view hunter's point was treated dealing with the shipyard. the health department -- i wouldn't trust anything they have to say about my community because my community is still dying from toxins because they were in cahoots with the epa. the director had to resign because not telling the truth about the community and the health problems the young and

narrator: but building more systems and more plants can't work alone as a sustainable solution. and, as in pittsburgh, as in new york, part of the answer lies in protecting the watershed. nelsen: we need to reduce the amount of impervious surfaces in our watershed, which are surfaces that don't let the water soak in and then create more pervious surface, whether it's by having driveways that allow water to soak in or different landscaping to try to eliminate the amount of runoff that comes off our land so that the system, even with the development it has, acts more like a natural system and filters that water. water quality and sewage infrastructure isn't the sexiest of political agendas, but by raising the awareness about water quality issues, we can create political pressure to get our issues solved. about 15 years ago, surfrider activists were protesting a beach for being polluted. the city council asked the police to escort them away. there was complete denial of the problem. 15 years later, water quality is on the agenda of every city council person in that local city, and

it's been through a treatment plant. and now it's in our lake and we're watering with it. narrator: these reuse and conservation techniques enable las vegas to exist in the desert. another important form of conservation is preventing leaks. man: every drop counts. all water systems have what they call an efficiency rating. so if you were to measure the water that goes into your system and compare it to the water that goes out, how much is unaccounted for? most states have a goal of 10%. ours is at only 5.5% right now. and we have plans to lower that to 4%. man: we actually have our entire distribution system mapped out in a computerized or electronic format. and we can locate our pipes, we can locate our valves, we can locate water meters that are out there. we've got small units installed in the distribution system. and they actually listen for leaks. we can schedule the repair, minimize its impacts to the surrounding community, and it minimizes cost, because obviously, if you've got a leak that's been leaking for sometime, you're going to see a lot of undermining of the
