Yes that is one of the advantages of a solar thermal also called "solar dynamic" system, but you really need a concentrating mirror or lens to bring the levels up. You also have waste heat and extreme cold that can be used in many ways. And yes it is not so sensitive to radiation as Photo Voltaic.

A thought about how one could use the temperature differential between sunside and nightside on a spacecraft.
If an external sunside heat collector contained a volatile liquid that could be superheated to pass into a turbine generator in the bowels of the craft, and the output cooled by radiators on the nightside, power could still be generated if the solar panels had to be furled during a solar flare episode.

Ueli, Jim, That's OK then! Was just looking for a suitable backup system. By the way, I am uncovering more and more electrothermal-powered missions, the latest...
Most ion drives do not spend much power on heating, Just enough to ionize it, but mostly it uses extrema charges to accelerate the gas. The MET uses...
My apologies, Jim, you are absolutely correct! No excuses for the dismal conversion. This is why NASA probes keep hitting what they shouldn't, by not ...
NASA has a much better record on hitting Mars than anyone else. That misstake has only once happened. That is not their problem. I think they should make the...
Yes, as far as I figure, we need to differentiate electric drives (such as ion engines) from electrothermal drives, such as METs. Big difference, I believe. ...
I think I hinted at that. I wonder who has been using the term electro thermal for ion drives. Jim Brown ________________________________ From: Ueli...
Ueli, Yes, I am clear on this one, and I think we need to label them differently. The point I was making on the stats, is how efficient these electric drive...
Sorry I thought you said the concentrating systems would not work well enough. On the micro gravity of an asteroid such heating systems make even more sense. ...
