Powerful microbatteries developed at the University of Illinois combine the energy capacity of lithium batteries and the power delivery of a supercapacitor.
Joel Barker's insight:
Dennis Meadows of Llimits to Growth talked about the importance of batteries in the arly 1970's. Now we are finally seeing the next wave of batteries that make episodic energy soiurces (wind generators, for example) cost and energy efficient.

Whip up your own dust devil to drive a turbine and create green electricity by just relying on the sun's heat
Joel Barker's insight:
This dramatically increases the range of application of windpower around the world. JB

GE's latest wind technology development is fabric-covered wind turbine blades, which are supposed to even more efficient that the fiberglass that is used now.
Joel Barker's insight:
JB--A paradox: to make it bigger, you need to go "local." Think of moving the jobs to the locale for energy production.

Japan has been successful at tapping methane hydrate, also known as flammable ice as a potential domestic energy source.
Joel Barker's insight:
A clear breakthrough in accessing this huge source of carbonate fuel. Better than coal by 50% but still more carbon in the atmosphere. JB

The Oxijet is an air shower that feels like it's at full pressure while using 50 percent less water.
Joel Barker's insight:
Very little material makes up the Oxijet even as it cuts show water usage by 50%. Great for Limits Tech! JB

The Holy Grail keeps getting closer. Superconductors are important right now even though they are full of hassles. This discovery is incremental but useful because of its ability to handle huge magnetic forces. JB
