Is there a fertilizer you could make with the help of solar energy? Answered
I'm thinking of further uses for solar energy, in addition to electricty, water purification, and cooking. Are there any chemical processes for making fertilizers which are fairly simple but require heat and or light? I know producing fertilizer is very energy intensive and usually relies on fossil fuels, so if we could move that over to microgenerated free solar energy, it could be pretty valuable.
