"Micropower"?
The compressor in the refrigerator in your kitchen is most likely the biggest drain on your bill. The laws of thermodynamics means it's pretty much at it's limits as far as drawing current, right now. Ain't gonna micro that any time soon.
Your airconditioner? That to isn't magically exempt from the Secondlaw.
Now, one spacecraft I recently worked needed a minimum of 8,000 watts of power at the end of an eight year life in LEO. That required a beginning of life surface area of 450 square feet. Yes, that was six fifteen by five foot panels.
Out in space, the efficiency of the solar cells are enhanced by the presence of raw ultraviolet.
Let's put it this way. That wing was so damn huge it prohibited the preferred disposal option of multiple controlled aerobraking entries prior to a final spash in the South Pacific. Nope, it was actually going to generate lift like an airplane and spin the satellite completely out of control.
Whatever, the point is that it takes A LOT of solar cells to make decent power, since those damn things aren't highly efficient. (Second Law, again), and more importantly, they degrade quickly, and will the wonderful government subsidy for first installation exist to help the fifth year refurbishment?
Tell us, oh technical expert, just how long photovoltaic cells last. Especially in a humid oxygenated atmosphere with birds crapping on them.
So? Almost all electronics that go down in submarines never get exposed to anything more significant that 70F and flourescent, the almost permanent weather forecast of the US submarine force. I know this from personal experience, 'cuz...guess where the reactor was I ran?
