Seedling asked:


Assume that the albedo of the solar panel is equal to the albedo of the surrounding land, and that the generator is not a blackbody, so that 100% of its power output falls within the microwave band.

Will this device warm the planet more than if it did not exist at all? Or would the visible light converted into electricity by the solar panel equally and exactly offset the energy contribution to the atmosphere from the microwaves, thus keeping total energy (and thus temperature) constant?

concerned_earthling asked:


If you have used solar cells to charge your laptop batteries or other batteries what did you use as the solar cell array?

Did you need any sort of diodes, resistors, capacitors or other things that I haven’t thought of to regulate to power flow into the device and or prevent a over charge spike or reverse a drain on the device.

jaid asked:


A commercial solar cell array can convert sunlight to an average power
output of about 10 Watts per square meter of solar cells (this is averaged over day and night, year round). How many square meters of solar panels would be required to provide a home with 8,760 kilowatt hours of electricity in a year?

Puresnow asked:


I’ve done a little research and the cost is not prohibitive, as far as I can see.

Do you ever have interrupted power?

How much did the panels/windmills cost?

How much was installation?

Do you plan to invest in alternative energy sources again? What, exactly?

Estimate your savings, please.

Elsie
