A molecule of uranium has a million times more energy than a molecule of coal.“ He and Nathan "Mosquito Zapper” Myrhvold are backing a nuclear approach. It’s called Terrapower, and it’s different from a standard nuclear reactor. Instead of burning the 1% of uranium-235 found in natural uranium, this reactor burns the other 99%, called uranium-238. You can use all the leftover waste from today’s reactors as fuel. “In terms of fuel this really solves the problem.” He showed a photo of depleted waste uranium in steel cylinders at the Paducah Gaseous Diffusion Plant in Kentucky – the waste at this plant could supply the US energy needs for 200 years (woah!), and filtering seawater for uranium could supply energy for much longer than that.

The Copenhagen Wheel – Teaser (via senseablecitylab)

Smart, responsive and elegant, the Copenhagen Wheel is a new emblem for urban mobility. It transforms ordinary bicycles quickly into hybrid e-bikes that also function as mobile sensing units. The Copenhagen Wheel allows you to capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost. It also maps pollution levels, traffic congestion, and road conditions in real-time.

Brilliant!
