A bit too hasty on this:
After all - only one kilowatt of solar per meter^2 on average may fall on the pond over daylight but 50 kilowatts of heat energy may be dissipated by the same area over the 24 hour day ... maybe not in the pond configuration but in the tube setup used by MIT.
50 kilowatts per hour would be too much and 50 kWhr per day would be too little. Frankly, too little factual detail is known to even guess, and that was a poor guess at that ...
.... but planners and alternative energy advocates must give the reports which have been published the benefit of the doubt.
There is a likelihood, based on these reports, that what appears to be in excess of 100% of the solar energy falling on a pond area is being converted into biofuel, and that could be true even if only 5% of the photons were being utilized.
