The Seattle Pi posted a great chart comparing the different feedstocks for biofuels. When Algae based biodiesel becomes a reality, there isn't much doubt that  it will be the "green" biofuel/biodiesel of choice.Click for larger image

As suspected ...

Rising oil prices were a boon to biodiesel producers this summer, as near-$150/barrel prices for crude oil made it more and more profitable to produce biodiesel from a variety of feedstocks. However, with that same barrel of oil now costing less than $50, margins have tightened up for makers of the green fuel.

Some ... and I point out some ...  Cincinnati area biodiesel oriented folks might appreciate a new "hot-button documentary" written, produced and co-directed by Scott D. Roberts call "Gas Hole." Its playing in Cincinnati's Esquire Theatre on July 16th at 7:30 and 9:00pm. If you are of the 'alternative' to gasoline type and enjoy a hard look at the history of oil prices, the politics of petroleum and the future for alternatives ... this might be something of interest.

Synopsis

Here's some good news passed on by way of the ColumbusTDIDrivers Yahoo list.

The Wall Street Journal blog posted an article which moves closer to the quest of making biodiesel from algae which meets fuel standards. We are one step closer to a fuel alternative that doesn't require food and traditional farmland to produce base oils for biodiesel production.

Columbus area buses have been using soy based biodiesel for the past couple of years but due to the high cost have decided to operate only on ULSD according to the Columbus Dispatch.

Instead, the fleet will operate strictly on ultralow-sulfur diesel.

"It's an economic, as well as environmental, decision," said William Lhota, Central Ohio Transit Authority president and chief executive officer.

Earthrace, an attempt to round the world in record time on biodiesel fuel, is halfway across the Pacific Ocean and is now 700 or so miles west of Majuro in the Marshall Islands. They arrived on one engine and departed 4 hours later back on two.

After leaving San Diego the crew and ‘unique’ boat made a quick stop in Hawaii to exchange crew, pick up food and refuel, but a couple days out experienced a high pressure injector line leak which sprayed a mist of biodiesel fuel throughout the engine room. The engine was shut down and speeds reduced to 15 knots as there were no spare parts onboard for this particular leaking pipe. There was talk of making repairs with JB Weld, but injection pressures for this high tech Cummins diesel are 35,000 psi — that’s asking a lot from epoxy!
