That's what I proposed in earlier threads concerning biodiesel. Part or all of the production could be transformed in BD, and the rest if any could be dumped/sequestered in a less refined form maybe (would have to be a non-rotting form). > Judging from the"Algae Bloom" on Lake Mead a few years ago, and the bloom that Jones Beene pulled up on Google where the Colorado river dumps into the Gulf of California, any major river can be used for floating sieve algae farms plenty of natural nitrates in rivers and lakes (and groundwater too, judging from how fast algae form in livestock watering tanks from wells over 100 feet deep).
The rotting algae "husks" are starch-cellulosic and ferment to methane, hence an abandoned coal mine filled with algae becomes an oil and gas well, Michel.

All that's left to work out now is the practical details, come on guys shall we run collectively for the Branson prize and solve the world's energy problems at the same time? :) > > Michel > > > ----- Original Message ----- > From: "Frederick Sparber" <[EMAIL PROTECTED]> > To: "vortex-l" <vortex-l@eskimo.com> > Sent: Wednesday, February 14, 2007 10:41 AM > Subject: Re: [Vo]: Re: The $25 Million Branson Climate Prize > > > > Thomas Malloy suggested "algae ponds in the southwest desert". > > > > I suggest floating filters-sieves as algae ponds on streams, rivers, and lakes, > > and Blanton's swimming pool, where the water passes through and the algae > > are contained in them for harvesting for dumping into abandoned coal mines for sequestering. > > > > Thomas Malloy's leaky canoe comes to mind as a demonstration. :-) > > > > Fred
