Palm Beach County in Florida is the latest municipality to switch its bus fleet to cleaner-burning biodiesel.
Palm Tran, with its 9-10 million riders a year, will switch its 115 buses to biodiesel in a few months. This story in the Palm Beach Daily News says it will be green in two ways: for the environment and for the county’s budget:
The burning of fossil fuels is a major source of carbon dioxide emissions, which contribute to the greenhouse effect. Another benefit will be a reduction in cancer-causing agents linked to the combustion of petroleum diesel.
Chuck Cohen, Palm Tran’s executive director, has been coordinating the switch with the county, which is planning the same change for its diesel-fueled vehicles, Cohen said.
“Biodiesel fuels have been found to reduce CO2 emissions by up to 78 percent,” Cohen said.
That figure, however, likely refers to the use of 100-percent biodiesel fuel over the life of the vehicle.
Biodiesel is a direct replacement for petroleum diesel and engines can run on any concentration. Cohen plans to boost the amount of biodiesel used in the blend from 5 percent to 20 percent within a year.
The money savings comes for the county in the form that it can run the buses on biodiesel without any modifications to its diesel engines… as opposed to another plan to buy pricey hybrid-fuel buses, which was too far out of the county’s budget.
The BioBike – a 100-mile-per-gallon, biodiesel-powered motorcycle – is racing 3,000 km (1,800 miles) across Australia.
Diesel cars are well-established in the market and renowned for their ability to deliver excellent fuel economy in comparison with their petrol brethren. But why haven’t we seen more diesel motorcycles? Well, diesel engines run extra-high compression pistons, and their sparkless ignition produces much stronger power pulses – which gives them excellent torque, but means that the engine casings need to be thicker and heavier to deal with the increased stresses.

Awareness for ethanol is rippling throughout the American consumer market. Industry leaders across the board attest to that. And it’s the IndyCar Series that is identified as one of the big catalysts that caused those waves of awareness to ripple and spread. Dave Lewandowski wrote an 
Now, however, it appears that maize itself may prove to be the ultimate U.S. biofuels crop. Early research results show that tropical maize, when grown in the Midwest, requires few crop inputs such as nitrogen fertilizer, chiefly because it does not produce any ears. It also is easier for farmers to integrate into their current operations than some other dedicated energy crops because it can be easily rotated with corn or soybeans, and can be planted, cultivated and harvested with the same equipment U.S. farmers already have. Finally, tropical maize stalks are believed to require less processing than corn grain, corn stover, switchgrass, Miscanthus giganteus and the scores of other plants now being studied for biofuel production.
Ethanol producer VeraSun is considering sinking $30 million into a process that would allow the company to also get biodiesel out of its ethanol production.
Seattle-based Imperium Renewables has inked an exclusive deal with Hawaiian Electric Company, which provides 95 percent of electricity for residents of the islands, to provide biodiesel for some of the utility’s generators.

Ethanol is gaining more ground in the motor sports arena and more leagues are getting on board with ethanol-enriched fuel. The
