 Okay now, I'm very excited to be talking to Winifred Norlander from the Nuon Solar team. They are going to describe, she's going to give you some indication of all the wonderful things they've achieved. But I'm going to move the conversation towards how these seemingly frivolous things are generating wonderful technologies that are going to be enjoyed by everyone. And first of all we need to really understand what machine we have here. Could you go through it Yes, so hi I'm Winifred and this is my solar car. So she's called Nuon and it's actually the seven solar car that we've built so far. As you can see it has a solar panel of about 6.3 meters and it's a silicon solar panel so it's basically the same solar cells as that you will find on your roof. The car has a top speed of 160 kilometers an hour which makes sure that it can drive during normal traffic and even be able to drive in a traffic dam or to be in the middle of a city and handle traffic lights. The car is built of carbon fiber which means that it's really light so it's only 150 kilograms which means that we can basically lift it with four people and move it off the road if it needs to be moved. This is where the driver sits. This is what we call the canopy and as you will see it's really thin like the rest of the car and it's made of carbon fiber. So this is the steering wheel as you can see and it has the braking and the gas panels on the steering wheel and not on the floor so it's all electrical and the only mechanical part is the brake which is on the right hand side which is our emergency brake actually. It gets really really hot in here during the race about 55 degrees Celsius and that's why our driver needs to take a lot of water with him so three liters for three hours and then all the sweat of course because the driver will be sweating a lot is actually drained down the car because there's a small hole in the bottom of it. Good now is it really true that you seek very thin people to drive the car? Well a lot of people think that but no because to eliminate the human element we're actually giving every driver sand with him or water to top off their driver to 80 kilograms so in that way it really is a technical race and not a human race. That's a good thing that's a good thing okay let's talk technology. The windows at the moment what are they made of? Acrylic perspex is it? Yes. There's some interest in something else? Yeah well I'm not entirely sure if I can tell this yet. No okay well the point is that there's materials advances are possible not just in the solar panels themselves will evolve and all that. Can we talk about you did some work with concentrators you've had an interesting aspect there? Yeah so as I told you before our solar car only has 6.0 square meters of solar array. Well this car doesn't actually have 6.0 square meters it only has 5.79 square meters which means that we still have a tiny piece of area left that we could use. So we actually built these concentrators with the last parts of the solar array and then during the race when we had a static charging stop we take them out of the trunk because this car actually does have a trunk and we take them out to do the static charging. So in that way we'd have the tiny pieces of solar cell and then the concentrator which is actually just bent glass will focus on that and we could still make use of it. And you've got the wheels the suspension you've made advances in that and it's further to go is there? Yes so as you can see you can't actually see the wheels because they're covered by well wheel covers and that's because of aerodynamics. The suspension is in there and it's of aluminium and at the moment we're looking if we can do some more optimization about that as well. And did you know that the aerodynamics of this car is actually only the same as a side mirror of your normal car? It's just incredible. The whole car has the drag of a side mirror that's unbelievable. So that's why it's so fast I guess. That's amazing. And in the Netherlands I don't know where you're famous for much more than tulips, windmills and people two meters tall. You obviously are doing amazing things. There's another team I gather in the Netherlands who have a car that actually donates to the grid. Incredible is that right? Yeah it's a solar car for multiple people so this is really a Formula 1 racing car and we're trying to push technology so that we used in the consumer business while the other car is more focusing on getting the car itself in the consumer business therefore energy to the grid. It's wonderful. And at the Netherlands this is a good place to be isn't it? I'm amazed when I go to the Netherlands in Amsterdam last week. There are a lot of electric vehicles now aren't there? Yes. There's an attitude, a good attitude and the politicians are talking of banning internal combustion engines are they? Yes a lot of the big cities already have banned some older vehicles and they're now stimulating the use of electric vehicles which is going really well actually. And there's also been some more really great changes in the Netherlands when we're talking about sustainable energy. For instance a while ago the first solar road was opened so this is a cycle track which is completely covered in solar cells, 70 meters long and it's already providing three houses per year of power. We have a talk on that and of course that could be dynamically charging vehicles as they go along which would be wonderful. So I suppose it's not your solar racing world but presumably there's scope for other things. We heard yesterday Professor Pietro Perlow who used to run Theat research and he's developed an electric castor vehicle which was everyone's having a laugh but the point is when it stops it's not just got big solar cells that come out as a sort of moving restaurant it has a telescopic turbine on a telescopic pole so he gets wind power as well and some people have done that with road vehicles although in the city there's no wind I suppose usually but is there any other types of harvesting that you might not be allowed in the race but do you encounter any of that world? Yeah so as you say we can't really use any other energy than the energy that we get from the sun so even though this vehicle would actually be really suitable for letting the wind push it we're not really allowed due to regulations but as you can see the vehicles build up like three wing shapes sort of that's also why it's so aerodynamic so the wind kind of still pushes it along also makes it difficult for the driver on the other hand but I guess that's one of the great challenges of being in the race. It's great I mean it is certainly in the tradition of the solar impulse plane going around the world and a tour or boat going around the world all on sunshine I can imagine and so in times to come it's difficult to dream and I can't ask you secrets anyway but presumably there will be better solar cells coming along and I know there's some research on transparent solar cells and the rules might let you but you could have solar cells all over that window and still see out of it that would be wonderful wouldn't it and I've got a car over the lights and everything like that and I don't know if it harvested some of them harvest infrared and ultraviolet I think you might be allowed that by the rules if there was something that came along I mean the research labs they do yeah it could be yeah that's great so good luck I think what you're doing is absolutely marvelous and we have the solar roads being presented at the end of our conference here so that's we're very close to that world and we look forward to seeing you in our event in California you're going to be a starter and in Silicon Valley we'll wow them the Europeans are doing very exciting things thank you very much if you'd like to learn more just go to our website www.newallsolderteam.com or follow us on Twitter at www.newallsolderteam.com and we'll keep you posted about the latest news on our solar vehicle wonderful you're very good wonderful you
