Floating microalgae ponds indeed Fred, but seas and oceans might be a better bet than fresh water surfaces, because of higher mineral contents and available surface area. 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).
The production would be transported to land for fuel or sequestration using either underwater pipelines or supertankers collecting it from farm to farm. Alternatively we could exploit the natural algae fields in the oceans with supertankers which would also do the harvesting and processing to BD, if it turned out to be cheaper. In any case photosynthesis + sequestering does seem to be the best bet to absorb excess atmospheric CO2, and I suspect that doing the photosynthesis part at sea would be the only way to do it on a sufficiently large scale. 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
