Fill the tank in 5 minutes to travel 600 kilometers without polluting: these are the cars we will have in the futurelunes, 26 noviembre 2018 The cars that are sold now will not be the ones that circulate within 25 years. One of the alternatives with more possibilities are hydrogen cars: they only emit water vapor and are charged in 5 minutes. Other alternatives, less developed, are solar or wind cars.Fill the tank in 5 minutes but not with gasoline, but with an exhaust pipe from which what comes out is water vapor. It is the alternative offered by hydrogen cars that are already commercialized in some countries.Unlike electric, the fuel cell is not recharged by a plug, but have hydrogen tanks in which it is mixed with oxygen to generate electricity. Many of these cars have a range between 400 and 600 kilometers.But these cars are not the only alternative, because cars like wind power are already becoming a reality. There are even some who recharge their batteries while they circulate. In the displacements the wind is used to generate energy and have achieved an autonomy of 110 kilometers.
