It turns out that, among other advantages for electric cars, they can carry more energy than hydrogen cars when you take the efficiency of transferring kinetic energy to the car into account. There was an interview with Elon Musk where he scoffed at the use of hydrogen and the use of fuel cells.
- freehunter 14y agoThe advantage of hydrogen lies in the speed of refueling, which is the main disadvantage of electric cars.
- stcredzero 14y agoThere's always battery swap-out. The problem with that is infrastructure cost, though. Seems to me that the Supercharger stations are getting the time down to 30 minutes through parallelism. If one could bring component costs down even more, one could have more parallelism. What about 15 or 10 minute charging times? I'm going to guess that plans are in place to exploit some serious economics of scale when they start building $30,000 cars. Once you have autonomous cars, this opens up the possibility of "battery trucks" once can rendezvous with on the highway to recharge without stopping.
