Hope photovoltaic devices and the provided systems will increase in their number soon.
Comparing solar energy only to fossil fuel energy neglects the biological equivalent system: photosynthesis. I think this was/is the big inspiration of it being possible. It also points to the whole problem with solar technology: energy storage. Which in the biological world we call that food. But it is good to point out the original development was for space which grid power was of no use for.
I wish I can download animations for my lessons
Good to see these helpful information here.
