science. ♪ music ] hey, guys, welcome to "techknow", i'm phil torres joined by dr crystal dilworth, marita davison and cara santa maria. this week cara and i went on a little adventure, there is a home called the honda smart home and it's probably the most eco-friendly energy-efficient house on the planet.

most people take a tour, check it out. carr ep and i decided -- karen and i decided to take it to the party. >> for science? >> absolutely for science. . >> reporter: believe it or not, cara and i are doing this for science. and this. and even this. admit it. >> smart tv. >> smart cara. >> we are pioneer guests in the 1944 square foot laboratory for sustainable living. honda teamed up with the davis. >> we want to get to a zero carbon future. >> if this is what zero carbon awesome. >> this is a honda smart moment. >> welcome.

>> the ground floor is full of furniture made from stapable materials. the floor, concrete, was constructed in a way to reduce carbon emissions. the kitchen is sleek, modern filled with modern appliances. upstairs, two bathrooms, a master with a killer bathroom. another standard room. i have my eye on the master. why is honda in the house business, to build a home to power itself and an electric car with energy to spare. michael con. >> g is the project leader. >> honda's involvement indicates that they are interested in more than just cars in the future. >> as we get more electric vehicles we'll have to be more careful in the way they integrate with the house and the electrical grid. putting the house and car together as a system, the system parts. >> honda is not releasing the

cost of their smart home, without his experimental technology, it would be similar to other high-end homes in davis. >> what is it like for people to come and stay the night? >> this will be the first night for anyone besides myself to stay here. >> we are doing the first outside slumber party. >> you are the first overnight gets. >> i get the big room. >> once i'm at the big bedroom... ..in the name of science i decided to take the fit ev for a spun. ♪ music ] with most cars you have to drive to a gas station to fill up and re-energise. with this guy i drive it home, plug it in, and the sun does the rest of the work.

i'm kinda digging it. hopefully carol will let me drive this around for a while. that must be cara. >> hello. i'm having way too much fun driving around town right now. >> i want to drive the electric car, bring it back. >> you got it. see you soon. while cara took a spin. >> bye. don't wait up. >> michael showed me how the house is built to make the most of the sun - whether it's low in winter or high in summer. >> we have all these lovely south-facing windows, but they are shaded. when we get into summer we don't get heat gape. but in the -- gain, but in the energy. >> the solar panels are on top.

>> we have a little bit of modern form. form following function. we want as much space as possible for the solar panels. >> on a sunny day the solar panels can produce as much as double the energy that the house needs. here is where some of it goes. >> this is where it happens. >> the right side is a 10 kilowatt lithowin battery. we can store and charge the car and buffer the energy flow to the grid. >> if there's clouds here, and you weren't pulling from the grid. how long could this charge the house or the car? >> depends what you do in the house. if it's off the battery you can run 10-15 hours. the bruins of the house is this -- brains of the house is this - a home energy management system. a prototype built by honda to balance sly and demand -- supply and demand. >> the integration is

happening - 250 channels. all the temperatures, the electric loads, water flows monitored and recorded. >> what was the clicking. >> it's the way the data logger picks through the channels. >> while phil got the big picture from michael. jonathan, an engineer at uc davidson's we were cooling center showed me some of the houses cutting edge technology. >> we are heating and cooling. >> this is in lieu of having traditional central heating. >> absolutely. instead of moving thermal energy around with air, we move around with water, delivering the heating and cooling through the floors and ceiling. >> if there's cold water swimming underneath and above colder. >> also, significantly, it's impacted by the temperature of the surfaces in the room. >> one of the experimental systems that uc davis is testing

in the lab is here, underneath the backyard. four 20-foot deep holes have been drilled into the ground creating a geothermal system. >> we drop a felix of fluid, running back to the heat bump. it's taking thermal energy from the ground, because the cold water may be going in at 45 and 50 degrees, and the ground is 55 or 60 degrees. >> if it's a slight differential the ground is warm enough to put that energy into the water inside of those tubes. >> exactly. >> and in this house nothing gets wasted. not even the heat from the water. instead, it goes into this heat recovery system. >> so the hot drain water runs down the inside of a perfectly straight pipe, and the cold water that is coming into the

house wraps around the outside of that drape line. >> so as -- drain line. as it comes in it warms up, taking less energy later to make it hotter if we needed tox. >> exactly. >> brilliant. nice and cool in here. then there's the lighting system, solid state led and five times more efficient than conventional lighting. they are designed to work with our own body clock. you designed all the light in the honda smart house. >> yes, we are wired internally to have lots of daylight in the morning, okay. >> that's blue lights. >> at night time you want to do the reverse, limit the blue light. you want lights that are warm and bias towards the red. the whole house quitens down, spectrum. >> the lights are designed to make us look good. >> people want a warm glow to

the light bulb. i want to look in the mirror and do my make-up. i notice the colours are vibrant. now, my first impression of this house, i was impressed with agree? >> i want to move into it. it was beautifully designed. the architecture was amazing, the interior decor ration was amazing. we realised that every square inch of that home was intentional. it was deliberate, it was designed in an eco conscious way you. >> even the insulation they use was 85% cycled newspapers and denim. they were so thought. in their attention to detail. >> a lot of the technology has been around for a while. what is it that - talking the

house to the next level? >> the home energy management system, communicating with the power grid, solar panels, car, every circuit in the house, tweaking each one to add a 5% efficiency even, that's where it stands out. >> a cool thing - a lot of houses lose energy because there's leaks - there's cracks in the walls, windows don't seal and a builder has to go through and cork up what they don't find. in this house there was an ingenious approach. they pressure ice the home, spray in a nitrogen solution that goes to the cracks, when they depressurized, they knew it was totally sealed. >> was there differents that you notices because the house as so special? >> no, everywhere from the hvac to the lighting to the electric design, the intention was to

maybe the house feel warm, inviting and liveable. in many ways they thought about the feeling of the home before they thought about how to make that feeling energy efficient. >> i mean, we were living in experiments. you guys were about to see us next at a slumber party in that experiment. break. >> we want to hear what you think about these stories. join the conversation. follow us on twitter and

[ laughs ] >> i pressed that button, i swear. >> 350. >> 350. >> press start. preheating. while we were busy cooling the house was busy too, adjusting the lights for evening, and tracking data. minute by minute checking where the power is going and where it's not. >> what are you guys hoping to learn from this?

>> we'd like to help propel the state of the art in the industry. most of the data we'll make publicly available, put it on the internet. anyone that wants to study energy use and they can use it to develop better equipment. >> we want to cover it. >> can we take a before and that. >> you're going to take a las arn yeah selfy -- selfie. honours? >> i would love to. >> eating. >> right. >> i'll let you clean up and... [ laughs ] 7 music ♪ ] >> we are about to find out how energy efficient lasagna tastes. >> i hope it tastes good. i feel like my reputation is on the line here. >> sure is. >> it's really good.

i'm enjoying this. >> mm. you're not faking like you're enjoying it. >> i'm not faking. this is 100%. >> then it was time to relax and check on the energy usage. >> with the tablet you can tell how much energy you produced, how much you are consuming, and you can also have a little bit of fun. a little tv. a load of laundry. a nice hot shower - all for science. then it was time for us and the house to go to bed. the next morning our scientific slumber party came to an end. it was time to turn the house back over in michael konig.

>> how did it go, you are the first overnight guests, tell me the truth. >> it was exciting, i loved it. >> yes, we trashed the place. it was a lot of fun. >> some of the appliances were a little too smart. we had to catch up. >> it took phil a while to turp on the oven. >> me too. >> what is really cool is the second. >> that saves water problems. >> that was the design. >> i love the way it woke up with us. i was sitting in bed doing work and all of a sudden the shades go up. it feels very connected to the house, not just the way the lights are, but knowing everything i'm doing, it's recorded, so when you flush the toilet, run the shower, all the data goes to science. we were energy hogs, because we came with a full crew and electronics. honda said the house is expected to consume around 18 kilowatt hours a day, less than the average home, consuming about 30.

the house delivered more than 19 kilowas of energy back to the grid. it was an honour being the first guests, we had a blast. thank you for letting us crash in the honda smart home. >> thank you, we are happy to have you back. >> we'll save you lasagna next time. goodbye home. >> needless to say i had a good time. house. >> i'm jealous you guys had a us. >> it was hard work. i tested every faucet, eating las arn yax. >> what about the accessibility for a home like this, is this american. >> some of the items, because they paid attention to details, things like the tables were certified wood and the bed was eco-friendly and cost a lot of

money, which is good, but the average consumer would have a hard time relating or getting close to affording it. the passive design, the way the home was built with the angle of the sun and the way the windows are, that are attainable. >> a lot of times it's about thinking about the items before you build and put it into your blue print. if you build a home, making it have a passive design wouldn't cost money. converting and refitting an existing home would probably b expensive. this is a research home. hopefully once the data is in, it will be scaleable. >> after having the experience, choose? >> that's a tough question. >> i think i'll have to go with the lighting. i loved how automated it was, how by day there's blue light, by night it was more like yellow, red.

i loved that. up. >> i'm wondering - with a home like this contributing to the grid more than it's pulling off of it. what will it mean for the energy industry in general? >> it's a fascinating subject. they are aware, welcoming this technology. that would be weird, instead of having a bunch of consumers, having people contribute energy to the system. >> i think that's ultimately the goal that we all want to achieve, and seeing a transition into using solar, into using geothermal, into using the different sources of energy. i think we'll see less and les reliance on coal. >> karen and i had a good time cooking lasagna, and that smile is gern un, i

-- genuine, i enjoyed it. be sure to follow us on instagram and tumbler for more photos from the field. when we come back we meet a friendly robot coming from the factory to you - after the break. youngest and fastest growing continent with young people that are full of dreams and ambition. last year in south africa, suweto, i held a conference with young people including a video conference from uganda. one young woman says we are looking to the world for equal business partners and commitments and not necessarily aid. we want to do business at home and be the ones to own our own markets. that's a sentiment we hear over and over again. when i was traveling throughout

africa last year, what i heard was the desire for africans not only for aid but for trade and development that actually helps nations grow and empowers africans for the long term. as president i made it clear that the united states is determined to be a partner, in africa's success, a good partner, an equal partner and a partner for long term. simply -- [applause] >> we don't look to africa simply for its natural resources. we recognize africa for its greatest resource which is its potential. [applause] >> we don't simply want to extract minerals from the ground for our growth. we want to build genuine partnerships that create jobs and opportunity for all our peoples. and that unleash the next era of african growth. that's the kind of partnership

america offers. and since i took office we stepped up our efforts across the board. more investments in africa. more trade missions like the one penny led this year. and more support for u.s. exports and i'm proud that american exports to africa have grown to record levels. supporting jobs in africa and the united states, including a quarter of a million good american jobs. but here's the thing. our entire trade with all of africa is still only about equal to our trade with brazil. one country. of alt the goods we export to the world, only about 1% goes to subsaharan africa. we have a lot of work to do. we have to do better, much better.

i want africans buying more american products, i want americans buying more african products. i know you do too, and that's why you're here today. [applause] >> so i'm pleased in conjunction with this forum, american companies are announcing major new deals in africa. blackstone will invest in african energy production. colcoal coma cola will partner h africa to bring clean water to its communities. g.e. will partner, marriott will build more hotels. all told, american companies are announcing new deals in clean air, aviation, banking, selling more goods stamped with that proud label, "made in america." and i don't want to just sustain this momentum. i want to up it. i want to up our game.
