Ad Astra Rocket Company and Cummins use hydrogen/biogas to power Cummins generator in Costa Rica

Green Car Congress

and EARTH University in Costa Rica. In addition, biogas production from biodigestors is being studied by EARTH University. The collaborative project was initiated in July of 2011 as part of an integrated renewable energy concept being studied by Ad Astra with application to distributed power architectures and other derivative uses.

Biomass fuels: challenges and opportunities – ET Auto

Baua Electric

Fossil fuels currently meet this majority demand, raising concerns due to potential CO 2 (a major greenhouse gas) doubling compared to preindustrial levels (approximately 285 ppm for about 400 000 years before the industrial revolution and reached 376 ppm as of 2005 and is still increasing). Carbon dioxide cycle of biomass-based fuels.

Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

Since 2005, when major greenhouse-gas emitters among the Kyoto signatories were issued caps on their emissions and permitted to buy credits to meet those caps, there has been more than $300 billion worth of carbon transactions. This concept is often called “additionality.” Perspective by Brian J. Donovan, CEO of Renergie, Inc.

Charles Babbage’s Difference Engine Turns 200

Cars That Think

Babbage set to work on the concept for a Difference Engine, a machine that would use a clockwork mechanism to solve polynomial equations. The concepts of interchangeable parts and standardization were still in their infancy. Byron was not allowed to attend university due to her sex, but her mother supported her academic interests.

National Research Council Report Concludes FreedomCAR and Fuel Partnership Should Continue to Include Fuel Cells and Other Hydrogen Technologies in Research Portfolio

Green Car Congress

This report is the third NRC review of the FreedomCAR and Fuel Research Program; Phase 1 and Phase 2 reviews were issued in 2005 and 2008, respectively. The Partnership should consider conducting a project to investigate induction motors as replacements for the permanent magnet motors now almost universally used for electric propulsion.
