[ausev] Electric energy transfer and storage limitations

[John Rumsey]

That is why I thought it might be good to take your
generator with you, using available fuels.  What
happens if the power grid goes out for weeks after a
storm or other disaster? Fuels might still be
available using hand pumps or using the electricity
from the car. In emergencies you might even power the
essentials in your house using power from your
steam-electric hybrid. You might also be able to drive
300+ miles to stay with relatives even when there is
no power grid for 250+ miles. Using the electric power
grid makes everyone too dependent on one power supply.

Imagine the outlet you'd have to plug into to recharge
quickly. Expensive.
