" Insight tech today scientists in Sweden have developed a super fast charging battery mate from the most unlikely of materials algae. Join me now from the museum's important current science and technology center is Alex fearing Tino."
" How well -- just about as long as people have been using batteries. We could make them last longer certificate our friend knee that energizer bunny here. But nowadays it's really not enough to half of long lasting battery we have solar batteries to charge quickly nobody wants -- stuck. Cellphones that that hasn't charged or. The second -- connecting flight with a deadly act -- like waiting for your iPod to recharge before you go to the jet exactly. So doctor Maria Strom and her colleagues at ups only university in Sweden has started looking into making battery electrodes out of people. But not just annual paper like this. They actually meet people electrodes and of the eighth but the fibers from common kind of foul smelling -- they pulled right out of the Baltic Sea. So why would dole decides to use algae. Well if you presume weigh in on some of -- algae based paper you've seen it it's me of millions of angry nano structured. Tiny fibers that some of these are thousands of times thinner than a human hair and so this algae based paper is much more highly textured than regular paper. What kind of like that the difference between this scrub pad and this piece of cardboard you know much much smaller scale. You can see the difference but watch how does that make a battery recharge faster. Well if you run that animation we say don't show you. All right let's take the animation."
" When you plug your battery charger what it's doing is re loading the negative electrode with negative -- it's all in typical batteries the electrodes are made of metal. And recharging can take minutes or more hours. In this new battery the electrodes -- paper -- of algae and they absorb the -- much more quickly. The battery can recharge in as little as eleven seconds. -- The key here is the medium scale textured surface of the -- paper which provides lots of surface area for the iron to attach to. In this way they can move even out of the electrodes quickly generating a very rapid recharge. "
" Wow so eleven seconds when can we get these algae batteries. How well you can we expect them even possibly with you to come but at at this stage there really still doing the basic science and it and so. So far they are. Not quite high enough voltage and not enough capacity to run anything like iPod or something like that come but you have to start somewhere. And so that these these bad batteries are already able to. Be very very lightweight and very flexible. And so. And so. They they only could be perfect for running things like. Medical implants war war. Sensors or any other device that's very small in requires constant -- source of voltage."
" What about how safe they are we're told now to keep batteries out of the trash because of some of the toxic chemicals inside battery so what about these algae batteries how safe are today right."
" So these batteries are made mostly out of keeper algae and salt. So now we should they be very cheap and an easy to make it almost any part of the world -- we should be very environmentally friendly. Alex -- no good to see you thanks thanks thanks for having me better."
