Happy Mother's Day

I called my mother this morning to wish her a happy Mother's Day and she announced she knew exactly what she wanted from me.
"Get your father and I off the damn grid" my mother said. She doesn't want me to buy anything, she wants research, information, ideas. Photovoltaic, wind power, passive solar, etc. Mostly she wants me to look into PV and passive solar. My father wants a wind turbine.
Go figure...
