JUICE BOX For many years, environmentalists have looked forward to the coming of net-zero-energy buildings. Now residential and commercial buildings can be outfitted with roofing tiles that double as solar panels, or with rooftop boxes like this low-profile unit that transforms gusts of wind into electric current.

Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load. The speed controller is connected to the motor and battery in the usual fashion, with an automotive-type blade fuse in line for safety.

In case of power outage at home, the DC pins in the charger can send juice back into the house, keeping the lights on. Just as there is an Apple ecosystem, so with home and EV battery systems you could wind up with a Ford setup, a Tesla setup, or a VW setup. Even so, world events are putting wind in the sails for backup power.

Though between the noise of splashing water, buffeting wind and 500 horsepower, things get a bit noisier when getting up to the electronically-limited top speed of 40 knots. So that higher-speed trip used ~5x as much energy as the low-speed one did (there may have been differences in wind/waves as well).

Connecting with history The archipelago of San Andres and Providencia is more than 400 miles north of the mainland of Colombia, and closer to 100 miles east of Nicaragua, but thanks to a historical wrinkle that is still being ironed out, it is part of Colombia. San Andres is not on the radar of many U.S. with motorcycles zipping around me.

Their initial idea was that garaged vehicles would have a two-way computer-controlled connection to the electric grid, which could receive power from the vehicle as well as provide power to it. This is good for the grid. It’s yet to be shown clearly why that’s good for the driver. Kempton and Letendre’s. In the UK, experiments are.
