just got a cabin with 40 acres with abundant trees no power or water
My intention is to power a generator using a gasifier. Currently i have 2 gennys to use, 1. 5500w gas 2. watt propane
i want to add solar and wind as funds become avail.
I am wondering how much "battery" its gonna take to run the chest freezer, 2 computers, tv with x-box (randomly) and a couple of other household power vamps ie: alarm clocks and such
Is it more prudent to use propane instead of the gasifier to run the 5kw worth of 12hrs / day for the business.
the idea being that the gasifier has to be loaded and warmed before gas is produced "is this me just being lazy"
need to know how much propane is used for 24/7 operation versus pounds of wood. I heard that 2 lbs wood = 1 gal gas

We should also remember that while electrification is often the most convenient way there are other more mechanical methods available.

These are the only "Made in the USA" NiFe's on the market. I'll be working with Hank soon, and we're set to blow the lid off some of the false data about nickel iron batteries. We will be publishing test data on every aspect of performance. They perform quite well when compared to lead acid, are far superior in some cases. There are some downsides, as with anything, but these aren't in the performance arena, and certainly not with the longevity.

It uses sheets of graphene , and regular water as electrolyte.
graphene wets out, and naturally spaces the next plate away at the optimal distance.
no toxic electrolytes either.
think this can also be charged by heat, as there is another story about that.
They show that it can be used as a heat sink, and directly convert heat to electric.
