Congress Still Hates Biofuel (For the Military)

June 20th, 2012 | by Charis Michelsen

The U.S. military is – perhaps unsurprisingly – one of the driving forces behind alternative fuel sources; after all, not being dependent on potentially hostile foreign countries for vital fuel is a matter of national security. However, in the short term, said alternative fuels are more expensive than standard fossil fuels, and that creates a few problems.

The EV Black Knight Rides Again: John Petersen on Mortal Enemies

June 11th, 2012 | by Breath on the Wind

In commerce, a black knight is someone who makes an unwelcome takeover bid. John Petersen is not an EV supporter. Rather, his disclosure exudes a contempt for the EV that is pervasive throughout his work, while he admits to previous commitment to lead-acid batteries and a present ownership in Axion Power. A recent article throws down the gauntlet as he tries to take over the EV conversation: the Black Knight rides again.


Perspectives on the Geothermal Energy Association Showcase in DC

May 29th, 2012 | by Breath on the Wind

The fourth annual GEA International Geothermal Energy Showcase concluded Wednesday, May 23, in Washington DC. The conference featured countries and projects in 6 different regions of the world: Asia and the Pacific, Europe, Turkey, Latin America, the Caribbean, and East Africa. Presentations by corporate and country leaders, for many of the projects, were very similar, but a few had unique challenges. Ultimately, what started out with policy, charts, and graphs ended up with a human face and concerns in Nevis and East Africa. The showcase was well-organized, resulting in a virtually flawless program.

May 27th, 2012 | by Charis Michelsen

Nissan has been quite enthusiastic about its electric car, the Leaf -- and with pretty good reason. It goes, it's comfortable, and it's cute to boot. The next step, clearly, is to take the tech that works so well in the Leaf, and turn it into a miniature cargo van


Understanding Wind Turbines and Heating/Cooling: “Eureka!”

May 2nd, 2012 | by Breath on the Wind

Are wind turbines that produce electricity "bad" and contributing to global warming or is it all just hot air? (Hint: the answer has something to do with the air, but not the global climate.) Our world is warming. Just a little, but it is enough to cause considerable and catastrophic climate changes. We know that for anything to warm there must be a source of energy. Wind turbines produce electricity. That is energy. Couldn't that be a source? Archimedes solved one problem by jumping out of a bath and running through the streets naked, exclaiming "Eureka!" ("I have found it" in ancient Greek). We can also understand the wind turbine effect by thinking of being naked in a bath.
