Kickin’ back with a frosty beverage I started thinking about all the amazing meals I’ve made already this summer. Grass fed beef burgers. Tacos. Burritos. Soups. Ribs. Fresh fruit salsa. Fresh veg salsa. Might note I’ve been on a bit of a salsa/corn tortilla kick. Freshly picked fruit. Veg.
When I went to buy wallpaper I went to a shop that sells recycled bits. They had wallpaper paste, wallpaper brushes, wallpaper trays; all donated. And two enormous bins of wallpaper. Very few with two rolls to match.
A pair of volunteers, lovely ladies of a later generation than even mine, hurried over when they saw I was looking at the various bits and bobs with my typical expression of puzzlement when faced with a new to me technology.
Testing Bokashi in a muldering toilet design
(or Poo digestion: phase 2)
For my primary material management I use an envirolet toilet (muldering toilet in a plastic box). But just before Christmas the cold weather meant frozen material had formed a mountain and plugged the exit.
I know. Kind of an odd topic, but while off grid waste management is seemingly without surprise, here’s a tip I picked up last year: Bokashi style composting toilets.
Bokashi is Japanese for “fermented organic matter.” You make an inoculate or microbe laden mash and by combining it with various organic materials use it to ferment and very rapidly compost those materials. That’s the theory.
Batteries are currently (ha ha) the weak link in the off grid solar equation. If you’ve gone through my site you know I’m a HUGE fan of lithium iron phosphate batteries. Basically flooded lead acid batteries are the equivalent of a 70s automobile. Ya. Looks like a car. But …
Still, if you’re doing a small off grid solar electric install lead acid aren’t horrible and they are cheap. So here are creeky’s top tips for improving efficiency and lifespan when hooking up lead acid.
There was some research done around 2008. First by a fellow in Africa looking for a way to cool the metal roofed homes that poor families lived in. Under the hot sun they became ovens. And he worked out a method of using two layers of metal roofing to draw cool air from the ground up between the metal layers of the roof to expel hot air at the roof peak. This cooled the tin. Keeping the homes usable for longer periods of the day.
Another researcher in Texas found he could use roof ridge vents, metal roofing and foil covered polyiso sheathing to move air out of the test home attic, cooling the attic from 130F to 80. Pretty significant.
