it has to be pumped into your tank under high pressure. and even then the amount that will fit in a tank only takes you a couple of hundred miles at a time. so the researchers figured instead of forcing hide jen atoms into the tank, they could seduce them. so instead of having to pressurize and jam the hydrogen into the tank yes. this is like a sponge that stuc tyd t basically into a hydrogen sponge. yes. yes. cooked chicken feathers. when you heat up the hollow hairs of t chicken fehers, own asken featr fi they be nanoporous. that means there s lots of really, really small powes for the hydrogen atoms to nestle into. you could have a surface area of a football field. and how much would it cost to have enough of this to do a tank of gas? that will be our estimation is around $500. so $500 to set up a tank.
