Product idea (living in a place where the power gets turned off).

Emergency electric start gas generator with downstream battery and inverter. Keeps battery full. Generator is sized to average load not peak and doesn't run all the time.

Being a PG&E customer makes life interesting.

The other business I find interesting is water catchment systems as the water goes away. It could be that your roof is entirely sufficient to provide household needs even in a drought year.

Every year is one step forward and two steps back. The future's so bright, you gotta wear tinted safety glasses.
