cently.
Okay, another tidbit I remember from that pbs homepower show is that the
flywheel used in the Rosen Motors hybrid turbine powertrain will spin on
for 6 weeks after the engine is shut off.
As for the grid upgrade, yes, I agree there would be an increased total
energy consumption. However what if instead of each car burning the fuel
inefficiently, the garage station does it for you in generating its own
power and spining its own giant flywheels underground.
When you're low on power you drive up to the station and get your own
flywheel spun back up to speed with some charge top off and away you go.
The concept of local energy generation isn't new either but it may
sometimes be more efficient than long distance generation and transport.
