If a car battery can be made to charge to 50% capacity in about a minute with a total range greater than 60 miles or so, then a very novel solution to charging electric cars becomes possible -- induction coils at stop lights and along highways.
- ajuc 14y agoIn the bigger cities and between them we could just connect electric cars to grid the whole time, and put energy meters in each car. Like trolleys. No need for big batteries inside the car, just supercapacitors for a few minutes worth of driving if there's some problem with the grid and you need to park safely. I wonder if people could buy electric cars like they buy cellphones - you sign a contract with a provider, you pay X USD per month for the car and access to the grid, additionaly you have access to free regular car if you need to drive somehwere the grid doesn't exist yet(but you pay for the fuel by yourself). The problem is infrastructure, I think.
