LoL，they keep saying Science can solve the world energy problem ， how many year already，they still can't solve it. Current EV also can't even fully replace gasoline car because for need 30min plus to charge the bettery that is wasting time. Technology should make our life easy and save our time not spend for extra 30min to wait for a car . Some of the people say just change another battery to solve the problem , but other side of people say they don’t want second hand battery. So this kind of technology can solve our current problem? This is future? When is problem can be solve? totally unknown .They just create another opportunity for us to choose different type of vehicle not solve the energy problem without oil. they keep talk about EV is good and future. So we buy new ev and spend more time to charge battery is this future? If they created infinity battery then the problem can be solved but what price they gonna sell?
