General   (General discussion, talk about anything.)

You'll need a battery pack off a fork lift truck, then about a thousand of those 99p calculators to fasten on the side of your bread van.
Maybe a couple of wind turbines on the roof, too.
But, after all this charging of your battery pack, you'll then need to put it through an inverter.

In other words ... efficiency has gone out of the window before you've paid for your diesel to run the van!
