About the cooling, we’ve been discussing this in the https://focusfusion.org/index.php/forums/viewthread/283/

In a nutshell, FF runs 50% efficient, which means that the 5MW electrical output is roughly matched by another 5MW of thermal energy to find a use for. This means that for some applications it could be pitched as a 9 or 10MW reactor.

So there is a need for efficient thermal conversion here. Interesting …

I’ve read the patent and dissected the Google video since the above post. Eric is actually predicting 42% efficiency in the Google Talk video.

The best plan outline that I can see right away is to pitch it as an energy source that will generate 4.2MW of electricity and 5.8MW of heat (~20MBTU)/hr at temperatures of around 400 degrees F for building and low-temperature process heating, to minimize the thermal pollution.

In short, the ideal prospect owns a large pre-existing heatsink like a factory.

Yes. Many of us have concluded that the cost-benefit of any thermal conversion/generation process would so far exceed the cost of just making more FF generators to create the same output that only easy passive heat uses would be worthwhile.
