“Kinetic Road Plates - Green power from the parking lot”

Kinetic road plates will soon power checkouts at a Sainsbury supermarket in Gloucester in the UK. Each time a vehicle drives over the plates in the parking lot, kinetic energy is converted into electricity and transferred back into the store.

Not new, but I just realized: you can’t call “green” something that produces energy by increasing the gas consumption of each car that goes through the parking lot, however infinitesimally.

We don't need newsletters, and we don't need Twitter; RSS still exists.
