Where's your entrepeneurship spirit?
There will be a chain of VOLT-n-NAP's all along the highways.
Charging stations can be also added at truck stops (where they nap anyway) as large trucks go to battery powered engines.
Look at all the jobs this will create.
A loaf of bread will, it is likely, cost $8 but heck, we're saving the whales, ya know!
Volt-n-Nap sounds like an erotic hotel.
