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 that the Obama Administration and 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 theyre not dangerous. And if perhaps a couple of them will be further detained because its determined that theyre dangerous for this country. So this was a promise that President Trump had made, and its a promise that hes going to keep. And hes not willing to be wrong on this subject. So what im trying to explain is that if youre a person that has a green card for whatever reason from yemen, and youre coming back and forth to yemen into jfk, i think its 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 its no big deal. There are so many questions that, for example, that didnt filter down to our customs people, who can come in, who cant . 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 f16 . And there will be more coming in. Theres 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. Ok, lets 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. Ky yours and mine. Two sensations that work together, so you can play togeth. Ky yours and mine. There goes my sensitive bladder. Sound familiar . Then youll love this. Incredible protection in a pad this thin. I didnt think it would work, but it does. Its called always discreet watch this. This super absorbent core turns liquid to gel, for incredible protection thats surprisingly thin. So i know im wearing it, but no one else will. Always discreet for bladder leaks the u. S. Navy is still trying to figure out why the most expensive destroyer ever built cant manage to sail. It broke down twice during its Maiden Voyage from maine to san diego. Avid martin has the story. Reporter if batman had a worship, it would look bike the uss zumwalt. Look at the most advanced warship the navy is bringing to the fleet. Reporter we rode with captain james kirk, no relation to star trek captain kirk. The zumwalt looks radically different. Its 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. Thats 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 with the most advanced technology that we had. Reporter those innocuous looking boxes house gun airliba capable of firing a shell more than 60 miles. If were 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, its 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 . Where we typically would have lookouts 247 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 . Its sweet, but you have to work for it. Were trying to keep up with the new technologies and understanding whats 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 . Its a brand new concept, new technology. Number one, its going to be expensive, because some of the technology is not going to work, or its going to take locker to develop. This program was started in the early 1990s. Reporter ron orourke 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 . Thats 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 elmo bud zumwalt, chief of Naval 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. Its 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.

Tum tum tum tum smoothies only from tums the latest technological challenge for scientists, trying to create a super battery. Its the subject of a new episode on nova hosted by david pogue. Heres a preview. Reporter you probably grew up thinking that batteries are 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 its 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 dont 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. Im 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 thats 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. Theyre both intermittent. Clouds come over on a sunny day and its gone. The wind stops blowing, its gone. You need a way to store it. Reporter some have proposed using banks of rechargeable batteries, like in our cell phones. But thats expensive and their life span is far too short. Which is why some companies have begun creating batteries that dont 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. 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 arent 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. Heres 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. Its basically a huge bathtub that freezes water solid overnight when energy is very cheap. So far what youve 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 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 doesnt have to create cooling. Its 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 winerys air conditioners for six hours a day. As a result, the winery saves electricity and lowers Greenhouse Gases by 20 tons a year. Thats an important step in fighting climate change. Now, thawing ice isnt the only force of nature that can store grid energy. Lets 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 sanders is the cofounder of amber kinetics in san francisco. And this bike is supposed to illustrate how their grid batteries work. Here comes the sun, im shining on your solar panels. Im 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 . Thousands of rpms. Reporter thats 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 its 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 cant 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 down on pollution, capture the power of, saturday ushered in the lunar new year. And 2017 is the year of the rooster. There were celebrations around the world. There was also a huge tv extravaganza broadcast from beijing, viewed by more than a billion people. Adriana diaz went backstage. Reporter its a dazzling feast for the eyes. With overthetop pomp that demands attention. A schizophrenic mix of dancers, athletes, and singers. The show is one of a kind. We have a wind range of routines to try to appeal to everyone. That range, of course, extends beyond the flashy stage. Propaganda, which has gained prominence under the current president , is also on display. Its a logistical high wire act that involves 13,000 performers, and cutting edge technology. Here at rehearsal, there was no shortage of bright lights and special effects, and these rehearsals have been rehearsing for months for five hours of eyepopping tv. It was a hodgepodge of elaborate costumes and what may make this the cutest show on earth, we saw children dressed as baby roosters. After all, 2017 is the year of the rooster. But the tight space and tighter schedule brings its challenges, said this dancer. We often rehearse until 1 00 or 2 00 a. M. , she told us, and some dont have time to eat at noon. They eat whenever and wherever they can. Still, she says its well worth it. It means so much to us in china, she plained. Its hard to make the shows cut. Only the elite survive. The show can launch a career and boost the celebrity of even the biggest names. Celine dion performed in 2013. And in years headliner is jackie chan, who was greeted with cheers at rehearsals this week. For chan, and the legions of other performers at this years show, the event marks not just a celebration of fresh beginnings, but of patriotism and pride. Adriana diaz, beijing.
