You are given 2000k square feet and have to choose one of these:
A) Cover the area with solar panels and produce electricity. Consider cost & efficiency of solar panels, inverter and any other necessary pieces.
B) With parts from home depot, construct a gigantic DIY solar water heater to make steam and run a steam turbine to make electricity. Again, consider cost of parts & possible efficiency of the rig.
I have no idea what the answer is, I just wanna see people argumenting and stuff.
