Best Viewed with IE or Opera. Sorry, Firefox works, but loses some sidebar layout,
'my profile' and other stuff... Anybody with a fix, please leave a comment. Many thanks in advance.

That said, if you must use Firefox (and I don't blame you, it's become my browser of choice, too)
...get the "IE Tab" extension. This allows you to view problem pages with the IE rendering engine. Very cool!

Alternative Fools: E85

By Michael Karesh
The United States has pledged to kick the oil habit before. But this time we mean it. Better yet, we have a solution that doesn’t require any of that furrin’ hybrid and diesel technology: E85. Produced from corn and other products grown in good old American soil, this 85 percent ethanol blend enables American-as-apple-pie small block V8s to burn less gasoline than a Prius. If every car, truck, and SUV were E85 now, why we could tell the Arabs to shove it! So all good Americans should buy an E85-capable full-sized SUV TODAY! Actually, on second thought, maybe we shouldn’t be so quick to “go yellow.”

Brazil, poster child of the E85 movement, has farmed its way to energy independence. But the same solution won’t work so easily for the US. For one thing, Brazil produces ethanol from sugar cane, a much cheaper foodstuff than corn or anything else we can grow in the decidedly non-tropical Midwest. Perhaps global warming will lend a hand? In the meantime, every ethanol booster not wedded to corn interests cannot stop talking about switchgrass. Research indicates that an acre of panicum virgatum might yield three times as much ethanol as an acre of zea mays. But even if switchgrass proves a fruitful source of ethanol, its potential impact on US energy policy is minimal.

Americans are gas hogs. While 186 million Brazilians burn the equivalent of about 10 billion gallons of gasoline each year (40 percent of it ethanol), 296 million Americans burn 150 billion gallons of gasoline each year (3 percent of it ethanol). In other words, if America really wants to be like Brazil, we should cut gas consumption use by 90 percent. Hint: not many Brazilians drive full-size SUVs. Otherwise, we’ll need ten times as much ethanol as Brazil to match the Brazilian fuel mix.
