Excluding Bowen's naive DH economically destructive energy policy the recent suggestion to use indoor solar power makes so much sense.No more short life a,c,d,what ever batteries required. Use SOLAR power.
For '35' years I have had the pleasure of owning a Canon 10 digital calculator LS-1000H 'only' solar powered.FM what mongrel has been hiding/buying this solar technology so they can keep selling their short life toxic indoor batteries. My calculator was used indoors in business now it never leaves the house and 'never' loses power. If yr serious about human waste start with the obvious. Then move onto Elon's NDB batteries.
