WARTHOG SOARS ON BIOMASS FUEL

The A-10C Warthog that took to the Florida skies recently on a fuel mix derived from the Camelina Plant will be far from the last to fly on alternative fuels, says the U.S. Air Force Research Laboratory (AFRL).
Research presentations outline specs for platforms as diverse as the F-15 and C-5 Galaxy cargo lifter.
The A-10 was the first U.S. Military aircraft powered solely by Biomass-derived fuel blend.
Senior Chemical Engineer Tim Edwards of AFRL's propulsion directorate says the alternative fuel program seek replacements for Petroleum-derived Jet fuels.
"We're not looking at different fuels for specific applications," he says.
"For energy and environmental security reasons, focusing on high-volume applications of renewable fuels yelds the highest payoff."
The A-10C fuel blends Jet Fuel and Processed Camelina, a crop in the mustard and kale family grown for animal feed and vegetable oil.
USAF researchers hope advances in Biomass/Jet Fuel blends will jump-start non military applications and bring down production costs with scale.

PENTAGON INVESTS IN SOLAR ENERGY.
(da DTI-Defense Technology International di giugno 2010)

The U.S. NAVY and MARINE CORPS will ramp up their use of solar power at U.S. facilities with a $100-millions investment in istallations on military property in the Southwest, West Coast and Mountain States.
The first 3 are planned in California and a formal announcement of locations is expected soon.
Utilities are contracting for development of the sites,with at least 40 Megawatts of photovoltaic plants set for costruction in California, Arizona, Nevada, Utah, Colorado and New Mexico.
Rather than feeding a grid, power will be consumed by the bases where the arrays are located.
The companies - SunEdison, Chevron, SunPower, Aecom Energy/Solar Power Partners and SunDurance - will build, operate, mantain and own the photovoltaic fields, and the services will purchase power through long-term contracts that last for at least 30 years beyond the completation dates in 2015.
Options could double the outlay to 200 millions.
The militay, one of the largest U.S. energy consumers, has been accelerating development of alternative energy.

Indipendenza energetica e capacita' di avvalersi di carburanti diversi sono alla base di molti progetti militari.
Basti dire che da vent'anni l'M1 Abrams puo' funzionare a benzina, gasolio, gas naturale o etanolo, e che molti mezzi militari hanno motori che possono utilizzare carburanti differenti con minime modifiche.

Il primo motore DIESEL funzionava con carburante vegetale, poi in seguito fu convertito al Petrolio.

Discorso diverso sono gli Aereoplani a getto rispetto ai Carri Armati.
