>> i'm working hard here for the people, the american people, and i'm american, too. >> reporter: the protesters here at lax national airport -- [ inaudible ] there were a number of people detained yesterday. today, the protests continue to grow, although they are very peaceful. but they tell me they have stepped up their patrols -- bringing in more men and women to make sure everybody stays safe. >> mireya villarreal. mireya, thank you. >> yesterday, what people need to understand is that 325,000 foreign travelers came into the united states. about 109 of those people were detained for further questioning because they came from the identified seven countries

both houses of congress have identified as being countries that harbor and train terrorists. they were asked questions. the vast majority of all those people were released. about a couple dozen people remain for further questioning. and my suspicion is those people will move on, as long as they're not dangerous. and if perhaps a couple of them will be further detained because it's determined that they're dangerous for this country. so this was a promise that president trump had made, and it's a promise that he's going to keep. and he's not willing to be wrong on this subject. so what i'm trying to explain is that if you're a person that has a green card for whatever reason from yemen, and you're coming back and forth to yemen into jfk, i think it's reasonable to expect that a customs and border patrol agent is going to have a few more questions for you to wonder why in the world you keep coming back and forth from yemen. maybe it's no big deal. >> there are

that, for example,ha filter down to our customs people, who can come in, who can't? is a green card holder as was originally interpreted, who is legally in the country, can they be barred? what about the iraqi pilots that are training right now in tucson, arizona, learning to fly the f-16? and there will be more coming in. there's so much confusion out there, and published reports are that neither the department of homeland security or the justice department or others were consulted about this before this decision was made. finally, lumping iraq with iran, right now we have several thousand americans who are fighting in iraq against isis, alongside iraqi military men and women. the battle of mosul has taken

military. is iraq the same as iran is? of course not. >> the "cbs overnight news" will be right back. ok, let's try this. ok, it says you apply the blue one to me. here? no. ah ok, here? maybe you should read the directions. have a little fun together, or a lot. k-y yours and mine. two sensations that work together, so you can play together.

different. it's part of the define to be tellny and sleek. >> reporter: what will president trump think when he finds out it cost an astronomical $4 billion? ray davis, who concerned as secretary of the navy, admits the navy tried to cram in too much new technology in too little time. >> we were designing while we built it. that's not a smart way to build a ship. >> reporter: he got that block eye from eye surgery. he spoke us with on his last day in office. >> the original concept was to have this very advanced destroyer that was primarily in a land attack role. so supporting ground troops, taking out enemy positions inland, having hyper precise weapons that could reach a long way inland, and to do with it

technology that we had. >> reporter: those innocuous looking boxes house gun airliba capable of firing a shell more than 60 miles. >> if we're ordered to, that person about two to three minutes before they will no longer be an enemy of the united states. >> reporter: but like the ship, its ammunition turned out to be expensive, $800,000 per shell. so the navy is looking for a cheaper round. one with a significantly shorter range. >> today, it's still unclear exactly what round is going on that ship, what that gun system will be able to do. >> reporter: there are only 147 crew members aboard the highly automated "zumwalt." about half of what a traditional destroyer carries. i see over there, you now have a video monitor? >>

lookouts 24-7 on the port side, star boardside and aft, we have cameras. >> reporter: still, he says there is more than enough work to do. >> the systems are brand new to the navy. we have to learn them from scratch for the most part. >> reporter: is this a sweet duty assignment? >> it's sweet, but you have to work for it. we're trying to keep up with the new technologies and understanding what's going on on board. >> reporter: the "zumwalt" has already suffered two mechanical breakdowns, one in the panama canal. >> this is the first ship of a class. this is the first time it got under way. things happen. >> reporter: maybe so, but right now the navy owns a $4 billion destroyer that cannot perform as adverbtized. how did that happen? >> it's a brand new concept, new technology. number one, it's goingbe

expensive, because some of the technology is not going to work, or it's going to take locker to develop. >> this program was started in the early 1990s. >> reporter: ron o'rourke has tracked this ship. >> as many as 32 of these ships were planned but that number was cut back. >> reporter: and what are they planning to build now? >> the program was truncated at only three ships. >> reporter: 32 down to 3? >> that's right. >> what happen it is you only build a small number, the price goes through the roof. >> reporter: everything about the "zumwalt" is controversial. its cost, its look, even its name. >> because dad was so controversial in what he had done, there were many people in the navy that did not want the name "zumwalt" attached to a navy ship. >> reporter: they are the daughters of the late admiral

operations from 1970 to 1974. zumwalt shook up what at the time was a very high bound service. >> he was that controversial in terms of integrating the navy with minorities and women. >> reporter: zumwalt was famous for messages he sent to the fleet called zeegrams, ordering an end to racism and sexism. >> if you look at the "zumwalt," you will see all races represented. it's ironic. the navy was the furthest behind among the services. >> reporter: history hasom ce to recognize admiral zumwalt as the leader who transformed the leader of the 20th century. the "uss zumwalt" is easy to recognize, but it will take a while nor the navy to figure out how to use it, and for history to know what to think of it. bursting with argan oil of morocco and notes of jasmine

batteries into the biggest machine of all, the united states electrical grid. that huge, aging, complex network of power plants and wires that bring electricity to our homes and buildings. and why would our national power system need batteries? two gigantic reasons. >> we don't have a shortage of electricity, we have a shortage of electricity at certain times and we have an abundance at other times. >> reporter: mike hopkins is ceo of a company that hopes to solve this problem. >> i'm sure you know the electricity system has huge surpluses at nighttime that have to be literally wasted, that has terrible deficits at other times of the day, peak hours, which results -- how do you know that? blackouts. >> reporter: that's the first reason we need batteries on the electrical grid, to even out the supply and demand. to time shifthe

of power from nighttime to daytime. but reason two is even more important to our future. power plant batteries would eliminate the biggest problem with solar power and wind power. >> they're both intermittent. clouds come over on a sunny day and it's gone. the wind stops blowing, it's gone. you need a way to store it. >> reporter: some have proposed using banks of rechargeable batteries, like in our cell phones. but that's expensive and their life span is far too short. which is why some companies have begun creating batteries that don't look like batteries. here in virginia, they set up two reservoirs. during the day when people need power, the water flows downhill, spinning turbines and generating electricity. then at night, they pump the water back uphill.

hydro. unfortunately, it only works in a few places where they have the upper and lower reservoirs. but american inventors aren't finished yet, by brings us back to mike hopkins. word is your new battery can be recharged and recharged infinity and is way cheaper. >> and i can show it to you right now. >> reporter: yes, please. >> here's the big reveal. the technology is a block of ice. a beautiful block of ice. >> reporter: hopkins' company is called ice energy. he invited me to a winery in temecula, california, to show me his product. the ice bear. it's basically a huge bathtub that freezes water solid overnight when energy is very cheap. so far what you've described is basically a big ice tray. how does that help anybody? >> the way it works is during the heat of

is hice, you get to the heat of the day, this device is connected to that device, which is a common, conventional roof top air conditioner. that air conditioner doesn't have to create cooling. it's getting ice cold refridge rant from the melting ice, using only 5% of the electricity in total that would have been required if just running that electricity consuming device during the heat of the day. >> reporter: in other words, these ten batteries can replace the winery's air conditioners for six hours a day. as a result, the winery saves electricity and lowers greenhouse gases by 20 tons a year. that's an important step in fighting climate change. now, thawing ice isn't the only force of nature that can store grid energy. >> let's take a look. spin the wheel. and into the points on the tire and the rim is in motion. and

>> reporter: seth sanders is the co-founder of amber kinetics in san francisco. and this bike is supposed to illustrate how their grid batteries work. >> here comes the sun, i'm shining on your solar panels. i'm charging up the fly wheel. now the sun goes down, how do i get stored energy back into the grid? >> an electric machine functions as a motor and equally as well as a generator. >> reporter: in other words, it uses cheap energy at night to spin up fly wheels. then during a day, a generator captures that momentum. if the fly wheel slows down, the generator creates electricity. how much do these babies weigh? >> this is about a 5,000 pound part. >> reporter: how fast is it going to spin? >> thousandsf

>> reporter: that's 8,000 rotations per minute. but the cool part is how they keep friction from slowing down that big steel wheel. first, a huge magnet levitates that 5,000 pound wheel so it's just barely resting on its bearings. second, they seal the fly wheel into this vacuum chamber. each fly wheel can store four hours' worth of electricity. the result, a battery that can't catch fire, and lasts for decades. all over the world, the quest is on to invent storage for our electrical network. something cheap that stores a lot, and lasts for decades. it might be gravity or ice or spinning disks. or some other idea. or maybe all of the above. but once we have them, we can reduce blackouts, cut

president trump's order banning citizens from seven predominantly muslim nations from entering the u.s. >> we are a better people than that. >> reporter: outspoken trump critic senator elizabeth warren was in the crowd. >> i'm here, because we do not discriminate against people based on their religion. >> reporter: other political power houses took to social media in solidarity. hillary clinton tweeted -- i stand with the people gathered across the country tonight defending our values and our constitution. this is not who we are. representative john lewis wrote -- this is a dark hour for america. those words rang true in seattle, washington, where protesters were pepper sprayed and at least 30 were arrested. six more were arrested in charlotte, north carolina. amid the protests, this iranian-american tried to make sense of what was happening at los angeles international airport.

>> i'm working hard here for the people, the american people, and i'm american, too. >> reporter: the protesters here at lax national airport -- [ inaudible ] there were a number of people detained yesterday. today, the protests continue to grow, although they are very peaceful. but they tell me they have stepped up their patrols -- bringing in more men and women to make sure everybody stays safe. >> mireya villarreal. mireya, thank you. john dickerson discussed president trump's latest executive order with white house chief of staff reince priebus and arizona senator john mccain. >> yesterday, the people need to understand that 325,000 foreign travelers came into the united states. about 109 of those people were detained for further questioning because they came from the identified seven countries that the obama administration and both house c

identified as being countries that harbor and train terrorists. they were asked questions. the vast majority of all those people were released. about a couple dozen people remained for further questioning. and my suspicion is those people will move on, as long as they're not dangerous. and if perhaps a couple of them will be further detained because it's determined that they're dangerous for this country. so this was a promise that president trump had made, and it's a promise that he's going to keep. an nhe'sot willing to be wrong on this subject. so what i'm trying to explain is that if you're a person that has a green card for whatever reason from yemen, and you're coming back and forth to yemen into jfk, i think it's reasonable to expect that a customs and border patrol agent is going to have a few more questions for you to wonder why in the world you keep coming back and forth from yemen. maybe it's no big deal. >> there are so many questions that, for exe,

filter down to our customs people, who can come in, who can't? is a green card holder as was originally interpreted, who is legally in the country, can they be barred from coming into the country? what about the iraqi pilots that are training right now in tucson, arizona, learning to fly the f-16? and there will be more coming in. there's so much confusion out there, and published reports are that neither the department of homeland security or the justice department or others were consulted about this before this decision was made. finally, lumping iraq with iran, right now we have several thousand americans who are fighting in iraq against isis, alongside iraqi military men and women. the battle of mosul has taken enormous toll on the iraqi military.

is iraq the same as iran is? of course not. >> the "cbs overnight news" will be right back. ok, let's try this. ok, it says you apply the blue one to me. here? no. ah ok, here? maybe you should read the directions. have a little fun together, or a lot. k-y yours and mine. two sensations that work together, so you can play together.

i checked, everything's there... wait a minute... hey... hold on, i can explain. you better have a good answer... switch to geico and you could save a ton of money on your car insurance. why didn't you say so in the first place? i thought you's was wearing a wire. haha, what? why would i wear a wire? geico. because saving fifteen percent or more on car insurance is always a great answer.

the u.s. navy is still trying to figure out why the most expensive destroyer ever built can't manage to sail. "the uss zumwalt" with a $4 billion price tag, broke down twice during its maiden voyage from maine to san diego. david martin has the story. >> reporter: if batman had a warship, it would look like the "uss zumwalt." >> welcome to the newest, most advanced ship that the navy is bringing to the fleet. >> reporter: we rode with captain james kirk, no relation to "star trek" captain kirk. though many have noted the coincidence. from norfolk, virginia to baltimore, where it was officially commissioned as a destroyer in the united states navy. >> "the zumwalt" looks radically different. it'sar

ship to be stealthy, sleek, without a lot of metal sticking up, a smooth surface. >> reporter: what will president trump think when he finds out it cost an astronomical $4 billion? ray davis, who served as secretary of the navy, admits the navy tried to cram in too much new technology in too little time. >> we were designing while we built it. that's not a smart way to build a ship. >> reporter: he got that black eye not in a bureaucratic battle, but from eye surgery. he spoke us with on his last day in office. >> the original concept was to have this very advanced destroyer that was primarily in a land attack role. so supporting ground troops, taking out enemy positions inland, having hyper precise weapons that could reach a long way inland, and to do with it with the most advanced technology that we had. >> reporter: those innocuo

looking boxes house gun barrels capable of firing a rocket assisted shell more than 60 miles with pin point accuracy. >> so if there's an enemy of the united states within the range of the ship, if we're ordered to, that person has about two to three inminutes before they will no longer be an enemy of the united states. >> reporter: but like the ship, its ammunition turned out to be expensive, $800,000 per shell. so the navy is looking for a cheaper round. one that would have a significantly shorter range. >> today, it's still unclear exactly what round is going on that ship, what that gun system will be able to do. >> reporter: there are only 147 crew members aboard the highly automated "zumwalt." about half of what a traditional destroyer carries. i see over there, you now have a video monitors instead of lookouts? >> where we typically would have lookouts 24-7 on the port side,

star boardside and aft, we have camera systems so we don't have sailors do it. >> reporter: still, he says there is more than enough work to do. >> the systems are brand new to the navy. most of them. we have to learn them from scratch for the most part. >> reporter: is this a sweet duty assignment? >> it's sweet, but you have to work for it. we're trying to keep up with the new technologies and understanding what's going on on board. >> reporter: the "zumwalt" has already suffered two mechanical breakdowns, one in the panama canal as it was transitting from san diego to it permanent port. >> this is the first ship of a class. this is the first time it got under way. you're going to have things that happen. >> reporter: maybe so, but right now the navy owns a $4 billion destroyer that cannot perform as advertised. how did that happen? >> it's a brand new concept, new technology. number one, it's going to be expensive, because some of the

or it's going to take longer to develop. >> this program was started in the early 1990s. >> reporter: ron o'rourke has tracked the "zumwalt" for the congressional research service. >> as many as 32 of these ships were planned but that number was cut back in subsequent years. >> reporter: and what are they planning to build now? >> the program was truncated at only three ships. >> reporter: 32 down to 3? >> that's right. >> what happens, if you only build a small number, the price goes through the roof. >> reporter: everything about the "zumwalt" is controversial. its cost, its look, even its name. >> because dad was so controversial in what he had done, there were many people in the navy that did not want the name "zumwalt" attached to a navy ship. >> reporter: they are the daughters of the late admiral elmo bud zumwalt, chief of naval

zumwalt shook up what at the time was a very high bound service. >> he was that controversial in terms of integrating the navy with minorities and women. >> reporter: zumwalt was famous for messages he sent to the fleet called z-grams, ordering an end to race imand sexism. those are on display on the ship for the crew to read. >> if you look at the "zumwalt," you will see all races represented. it's ironic. the navy was the furthest behind among the services. >> reporter: history has come to recognize admiral zumwalt as the leader who transformed the leader of the 20th century. the "uss zumwalt" is easy to recognize, but it will take a while nor the navy to figure out how to use it, and for history to know what to think of it.

rise above joint discomfort with move free ultra's triple action joint support for improved mobility and flexibility, and 20% better comfort from one tiny, mighty pill... get move free ultra, and enjoy living well. the latest technological challenge for scientists, trying to create a super battery. it's the subject of a new episode on "nova" hosted by david pogue. here's a preview. >> reporter: you probably grew up thinking that batterirees a those things we put in flashlights. or maybe the rechargeable ones that come in cell phones and laptops. but lately, batteries have been popping up in much bigger gadgets. like the electric cars. and now it's time to install

batteries into the biggest machine of all, the united states electrical grid. that huge, aging, complex network of power plants and wires that bring electricity to our homes and buildings. and why would our national power system need batteries? two gigantic reasons. >> we don't have a shortage of electricity, we have a shortage of electricity at certain times and we have an abundance at other times. >> reporter: mike hopkins is ceo of a company that hopes to solve this problem. >> i'm sure you know the electricity system has huge surpluses at nighttime that have to be literally wasted, that has terrible deficits at other times of the day, peak hours, which results -- how do you know that? blackouts. that's how you know it. >> reporter: that's the first reason we need batteries on the electrical grid, to even out the supply and demand. to time shift the availability of power from nighttime to daytime.

but reason two is even more important to our future. power plant batteries would eliminate the biggest problem with solar power and wind power. >> they're both intermittent. clouds come over on a sunny day and it's gone. the wind stops blowing, it's gone. you need a way to store it. >> reporter: some have proposed using banks of rechargeable batteries, like in our cell phones. but that's massively expensive and their life span is far too short. which is why some companies have begun creating batteries that don't look like batteries. here in bath county, virginia, they've set up a dam and two reservoirs. during the day when people need power, the water flows downhill, spinning turbines and generating electricity. then at night, when power is cheap, they pump the water back uphill. they call this system pumped hydro. unfortunately, it only works in

a few places where they have the upper and lower reservoirs. but american inventors aren't finished yet, which brings us back to mike hopkins. word is your new battery is environmentally perfect, can be recharged and recharged infinity and is way cheaper than the lithium battery. >> and i can show it to you right now. >> reporter: yes, please. >> here's the big reveal. the technology is a block of ice. a beautiful block of ice. >> reporter: hopkins' company is called ice energy. he invited me to a winery in temecula, california, to show me his product, the ice bear. it's basically a huge bathtub that freezes water solid overnight when energy is very cheap. so far what you've described is basically a big ice tray. how does that help anybody? >> the way it works is during the heat of the day after this is ice, you get to the heat of the day, this devi i

connected to that device, which is a common, conventional roof top air conditioner. that air conditioner doesn't have to create cooling. it's getting ice cold refrigerant from melting ice, using only 5% of the electricity in total that would have been required if just running that electricity consuming device during the heat of the day. >> reporter: in other words, these ten batteries can replace the winery's air conditioners for six hours a day. as a result, the winery saves electricity and lowers greenhouse gases by 20 tons a year. that's an important step in fighting climate change. now, thawing ice isn't the only force of nature that can store grid energy. >> let's take a look. spin the wheel. and into the points on the tire and the rim is in motion. and you have energy storage. >> reporter: seth sander t

co-founder of amber kinetics in san francisco. and this bike is supposed to illustrate how their grid batteries work. >> here comes the sun, i'm shining on your solar panels. i'm charging up the fly wheel. that i get. now the sun goes down, how do i get stored energy back into the grid? >> an electric machine functions as a motor and equally as well as a generator. >> reporter: in other words, it uses cheap electricity at night to spin up enormous fly wheels. then during a day, a generator captures that momentum. as the fly wheel slows down, the generator creates electricity. and these aren't exactly bike wheels. how much do these babies weigh? >> this is about a 5,000 pound part. >> reporter: how fast is it going to spin? >> thousands of rpm. >> rep

rotations per minute. but the cool part is how they keep friction from slowing down that big steel wheel. first, a huge magnet levitates that 5,000 pound wheel so it's just barely resting on its bearings. second, they seal the fly wheel into this vacuum chamber. so there's no air friction, either. each fly wheel can store four hours' worth of electricity. the result, a battery that can't catch fire, never loses charging capacity, and lasts for decades. all over the world, the quest is on to invent storage for our electrical network. something cheap that stores a lot, and lasts forad deces. it might be gravity or ice or spinning disks. or some other idea. or maybe all of the above. but once we have them, we can reduce blackouts, cut down on pollution, capture the power of the wind, and let solar power really start to sh
