People were making ethanol at home long before there were cars. They called it moonshine. With gas prices going through the roof and everyone worried about global warming, a California company is betting people will jump at the chance to use the same technology to turn sugar into fuel for less than a buck a gallon.

E-Fuel Corporation has unveiled its EFuel 100 MicroFueler, a device about the size of a stacking washer-dryer that uses sugar, yeast and water to make 100 percent ethanol at the push of a button.

"You just open it like a washing machine and dump in your sugar, close the door and push one button," company founder Tom Quinn told us. "A few days later, you've got ethanol."

( Is it really that easy? )

What does it say when one of America's most powerful families wants to shake up the world's largest corporation because it isn't sufficiently green?

Descendants of John D. Rockefeller, who founded Exxon's predecessor Standard Oil in 1870, will begin a campaign today to split the role of chief executive and chairman of the board, a role held by Rex Tillerson. Why? He has failed "to address the future of energy and related industry  hurdles,” according to a statement released by the family.

More than 100 Rockefeller descendants hold shares in Exxon through a variety of trusts, but the exact percentage is unknown. The campaign is being led by Neva Rockefeller Goodwin, an economist and great-granddaughter of John D. Rockefeller.

The timing is interesting. Last year, Exxon Mobile posted the largest quarterly profits in corporate U.S. history. Exxon is rolling in dough. You'd think this would keep everybody happy.

What's the royal beef? Read after the jump.
