Lee Cronin, John, Nissan discussed on The Naked Scientists
Forget. We have our guests who I told you about this creature. It makes this interesting sound. It also has three stomachs the biggest eyeballs of any land dweller and has a wingspan of about two meters. So that should put you now now. Well and truly on the path was identifying what this mystery creature. Is Tim question here from John. Many of us are thinking of changing your traditional cards for one powered by literacy behind begin to charge to these. Electric vehicles emerged to. There's no private parking spaces very good point. I like this question a lot but it does require me to sort of predict the future a little bit which is not necessarily my forte. So at the moment the UK has around about about one hundred and fifty thousand electric vehicles and about twenty thousand public charging points but the vast majority of electric car charging happens at home. And that's partly partly because it's slow so if you want to charge for example a Nissan leaf which can do about one hundred fifty miles on a full charge to charge it from nothing to completely full takes depending the challenge Between six and eleven hours so that is you poke home and you plug it in and you leave it overnight but what we are increasingly seeing is a talk of challenging code rapid charging which happens almost five times the speed of the sort of charge. You could get at home so a private parking spot might not be necessary with one of these because they could charge not just this leaf but a much bigger battery in less than an hour so for example. If you're out on a long drive it's no longer a case of just being a commuting. It's you pull over on the side of the road. You have a cigarette break in a cup of tea and half an hour later your car could have another two hundred miles in it. And that makes it a big difference from what we're currently experiencing a lot of now. I was talking to Lee Cronin whose professor chemistry at Glasgow and he told me could be as go that he has. Ah come up with a liquid which has got a very high energy density and it's based on the chemical tungsten and he can drain this chemical into a sale. And you get the literacy out of it depleting the liquid of its electricity so it changes. What's called the oxidation? State of the tungsten surrendering enormous amounts of electricity prices to recharge the cell drain out the depleted fluid and put fresh one in. And so he's saying the actually. This might be the future of electric vehicles where it uses exactly the same infrastructure restructure us at the moment for petrol stations. And things you go in and put a fluid into your car. which is the energy and differences? Here you just have to have a system that puts fresh fluid in and takes fluid out but basically soclean uses all the same way we used to work in. That might be quite attractive yet. There are lots of different ideas that I mean. If we had a story and you scientists a few weeks ago about a battery the the principle you could charge it up ten minutes. We had another one that could fit in your smartphone and would lost five days but the thing with these ideas is they're not really off the ground yet. What you you need? A battery is for it to be able to work just.
