Not solar panels – solar *cones*. That spin to keep cool.

Grist gives hope for affordable renewable energy from the engineers who’ve discovered that cones can make solar power cheaper than coal:

The company is called V3Solar (formerly Solarphasec) and its product, the Spin Cell, ingeniously solves two big problems facing solar PV.

The conical shape catches the sun over the course of its entire arc through the sky, along every axis. It’s built-in tracking.

The Spin Cell concentrates sunlight on plain old (cheap) silicon PV, but keeps it cool by spinning it.

It’s just so damn clever.

Design. Score one for design.
