Lab demonstration of the group’s new lithium-polysulfide flow battery contained in a simple flask.
The U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University scientists have developed a relatively cheap, long-life “flow” battery that can be used to mitigate power fluctuations from solar and wind energy plants, therefore enabling them to become major suppliers to the electrical grid.

Self-healing artificial leaf.
Scientists reported the creation of the “world’s first practical artificial leaf” back in 2011. The leaf mimics the ability of real leaves to produce energy from sunlight and water. Touted as a potentially inexpensive source of electricity for those in developing countries and remote areas, the leaf’s creators have now given it a capability that would be especially beneficial in such environments – the ability to self heal and therefore produce energy from dirty water.

Bladeless wind turbine
A new model of a wind turbine has no blades. In fact, it has no moving parts at all. Designed by Dutch architecture firm Mecanoo, the electrostatic wind energy converter (EWICON) prototype is currently on display at Delft University of Technology. (Video)

Fracking rig in North Dakota.
Today’s North Dakota, flush in its energy frenzy, has been characterized “the luckiest place on earth” by Chip Brown. His New York Times Magazine article showed chief executives and miners both giddy about their topographical luck and only slightly nervous that this boom would end as the last ones have ended in a bust.

Body-powered devices eliminate the toxic waste generated by the heavy metals used in the billions of batteries we currently use each year.
A startup in Corvallis, Oregon, has developed a small chip that can turn body heat into electric energy. The chip absorbs heat directly from the skin and then channels energy through a thermoelectric generator that converts it into electric power. In the future, the chip will enable us to power and recharge our handheld and wearable electronic devices with our own bodies.

When heated atoms can move with different levels of energy, from low to high. With positive temperatures (blue), atoms more likely occupy low-energy states than high-energy states, while the opposite is true for negative temperatures (red).
The coldest temperature possible is most often thought to be absolute zero. Researchers have now shown they can achieve even lower temperatures for a strange realm of “negative temperatures.”

There are currently over 1.5 billion people in the World who have no reliable access to mains electricity. These people rely, instead, on biomass fuels (mostly kerosene) for lighting once the sun goes down. GravityLight is a sustainable lighting solution powered by gravity. (Pics)
