I have seen those rocket stoves on YouTube. It uses the hot smoke to warm up the walls and seats, and the heat is retained. It seems to work well.
You should check out Solar Cabin on YouTube for information on setting up a simple solar system. Since you are using wood for heat, you should be able to power everything with less than a 2,000-watt solar system. It is heating and cooling that uses most of the electricity. The guy with the Solar Cabin channel uses wood for heat and some propane for his stove and on-demand water heater, and his solar power system is only about 600 watts to run his refrigerator, lights, TV, computer, etc.
Some states allow a person to sell electricity that they put back into the grid. This is the simplest way since all you need are solar panels and a grid-tie inverter for an on-grid system. If you produce enough electricity your utility company will pay you.
Yeah I've been reading and watching a lot of videos, I'll really amp it up when I'm about ready to actually do the first set of stuff. My state will buy the extra electricity. It's set up pretty nicely, I think. They do a 1:1 credit ratio. 1 kwh used = 1 kwh produced for each billing month. So I don't need nor want to go off grid, although I'll do modular backup system though, if I can, and I think I can but need to read more.
Now, any credits that roll over are then worth a percentage of a credit. I can't remember the specific value but it's somewhere between 40 and 60%. So to break even you need to factor in that percentage if you produce more electricity in the summer then in the winter and/or your usage changes.
At the end of a calendar year you can let the credits roll over to the next year or cash them in. So most likely at first I will just roll them over so I don't have a bill ever, but if I'm producing enough, even during the winter that I won't have a bill anyway, then I'd cash them in. By doing the system myself, I'm looking at 3-5 years to pay for my initial investment, at current prices. Estimated life span of my equipment is 50 years. If you factor in my time and assign a reasonable living wage to my time, it's much longer but I really don't tend to look at it that way.
I'd also like to tie in some wind power, maybe some micro hydro electric and very likely some themo electric. I could use a bank of TEG's in with a heat exchanger/heat sink systems that connects my RSMH to my inground floor heat system.
20 watts of tegs running for 24/7 is the equivalent to 100 watts of solar panels in southern cali in the summer in terms of total output.
In the event of an outage and say my panels are covered in snow or it's raining, cloudy, at night, whatever, even a 20 watt TEG system could keep my lights on and a freezer/fridge reasonable cool.
I'd like some exercise equipment connected in too, eventually. I know the output is ****, but bicycling at an average speed for an hour will power some basic lights all day.
I'd like to look into biogas more too. I'm thinking a small biogas unit that collects and stores the gas in a tank that can be used to run a generator during emergencies. The overall efficiency will suck, but just the backup safety net at such a low cost is just amazing.
