"Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway." –Andrew Tanenbaum, 1981

We deliver everything else by road. We should deliver power by road. The roads are already there. Once most long-distance trucking is done by robot (~10 years me thinks), there will be plenty of bandwidth. We need "standard units of power" (Sups) that are interchangeable with and usable with everything that produces and consumes power. The interfaces should be standardized. The internals can be proprietary.
