Off The Grid

drill a level or a plumb hole

A couple of weeks ago, I set up a sand battery to provide stable heat and humidity to an indoor greenhouse. It is a 60v commercial heating element directly connected to two 310 watt solar panels (series). The container is an obnoxious red thing I found at the thrift store. The sand mixture is 50# of playground sand and 5# of aluminum shavings from eBay. There's a bowl of water on top of the sand that adds humidity when the sand is warm. Ever since I installed it, the greenhouse has maintained 75 to 80 degrees f and 50 to 65% humidity. I installed a cheap shunt into the system this weekend and measured about 2kwh of energy into the sand, stored as heat.

In the UK... Banking apps can now read which apps you have installed and also from where. You installed something they don't like? Sorry, can't access your money until you stop your wrongthinking. @BC_FreedomFighters

It may not seem offgrid'ish but a penny saved is a penny earned. Insulated and efficient houses are relevant to off grid.
