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