[snip] Add that 25.2 to the 36.7 and subtract 48 input and you get 14W excess.. I think you can pretty confidently state that it is over 10W. Nice work. Thanks. Is there any way to guesstimate - assuming the best reasonable kind of insulation is added to retain heat, something like aerogel, etc - how much more mass of active wire (if any) would be necessary to get close to a nominally self-sustaining system?
