Ha, Joep I know too well about todays electric prices (slightly lower up here, but still…) What I meant was if the pay was 4 cents on top of hourly spot price. 40 cents sounded too good to be true. Best deal I’ve found here is 1 cent on top of hourly spot price. Also, we have a 6 cent gov subsidy on top of that, but that’s all.
Last few months I’ve avaraged about 18 cents/kWh for my production (incl subsidy). 8 years pay back time at this rate.

Yes, energy is fun. Especially if you can make/ spare money with it. You get a lever/ crowbar effect ( free translated 
).
Now a gasifier solution for the three dark months. As long as we can use the surplus from the summer in the winter , that is not urgent. In Belgium they had the same arrangement and bang, shot away, just like that. Here in Holland we talk to much, but it is going away some day….

Wish i had room for that many panels on top , My feed in tariff ends in a year or two , 10 years ago when i first installed solar electric cost per KWh was around 25cents and i got paid 65 cents for my solar its been a good payback really and also helped me make the most of my charcoaling electric generating because during the days i don’t like to use the grid and so send back as much as i can while i run the house on batteries and charcoal .

Got to buy this for about 50 dollars, 20 “diameter and 28” high, with a nice lid for the condensation as well. Now a question, is there stainless steel flux wire for the mig?

Yes Jan they do make flux wire for stainless steel. In the US the brand is Blue Demon.

Thanks Cody, then I’ll look if it’s here too.

Hi Jan, this type of stainless is perfectly weldable with ordinary wire too (ofcourse the weld and areas around starts to rust) It also really nice to weld with ss sticks.
That lid looks exactly the same as the one i use for my filter, (found it at Stena Recycling)

JanA,
I’ll echo what GoranK said. Use mm SS sticks to weld with. The 1.6mm SS sticks (1/16") I got from KristijanL work much better.
The Blue Demon flux wire I tried seems to under flux poorly. Maybe just me. Maybe my welding machine.

Ok, sticks are easier to find, I might even have them at home

When visiting the old-engine show, there was a swap-meet, these followed me home, a stainless steel milk jug, good for some gasifier/filter build, these are really cheap, people only wants cupper or galvanized steel, for the look’s, for decoration (to put flowers and sh*t in).
The cooling fan im going to try to make a small wind turbine out of, it has adjustable blades.
I think about using a hub-motor from a howerboard toy i got for free. Drive it through a reduction, this fan probably spins fast.

Yes, Goran, there is a nice 0.5-1kW Generator in that blade!

I don’t know if you have seen this guys channel Goran. He does a lot of projects converting different objects to wind plants. May be worth a look.

That is probably about right, it is maybe double that in the US IF you DIY the install, and the permitting/inspection aren’t a lot. Usually it is 7-12 years otherwise provided the installers aren’t just profiteers.
For 65c, I totally would have been running woodgas through the solar inverter on cloudy days and moonlit nights.

Here is the wilhelmson book starting about page 66 it talks about weding SS. 
I just found this looking for the welding textbook. Which has some decent general info even though they are selling their products…

I found the american welding society 9th edition circa 2003 volumes 1-5, which is like the unabridged version of the textbook but they are huge files and are like 800 pages long so I can’t post them. Of course are missing some of the tech developed in the last 20 years. Like Toyota patented a welding process I think for friction, ultrasonic or spin welding aluminum a year or two ago.
All and all, you might be able to read the whole thing as winter reading if you live on say the dark side of the moon.
It is a good idea, but those blades won’t be very efficient. A wind turbine uses airfoils which is similar to airplane wings or prop, which bumps the max efficiency from like 10% to 33%. (and also requires a bit more windspeed to get going) You can get the airfoil shape with 4-6" pvc pipe. And they do tilt them, so if you want more power further on down the road, i would probably start there. And also look at replacing the hoverboard motor with say a rewired front loading washing maching motor. may help boost efficiency as well.

Thanks for the advice Sean, i had the feeling it would’nt be perfectly efficient, but it’s going to be more of a “fun” project, im probably going to disguise it as a “garden ornament” like a “scale model” of them old pumping wind mills (aermotor or “ideal”) thinking about making the housing and tail fin out of copper for the look’s.
Those washing machine motors i’ve seen many have used, so some years ago i saved a scrapped washing machine just for that purpose, but in this case i think the hooverboard motor will do fine? It seems to be a good type for a generator, according to some Youtube videos, and diy threads?

Goran I have seen people use those 3 wire hub motors fairly often for windmill generators. It will need a rectifier to output DC, those brushless motors are secretly AC motors.
Also have seen the opposite of that using the cheap windmill motors and powering it with a brushless dc controller. They don’t have as much torque but they do have a higher RPM per Volt.
I’d like to get an alternator and magnetize the crab claw to reduce a maintenance schedule. Some have used loudspeaker magnets to do so without having to cut away at the claws.

And we finished the last set a few weeks ago. Only delivery in this place, no usage. In a p@ssing contest with a friend of mine I won in kW installed and thought to get the best price. No, he got the jackpot €0,60 for delivery and €0,85 if you consume.
Bad neighbourhood , so we used anti-theft bolts and nuts on diy frame. Fun to make and first to get it operational. Only piece missing is remote monitoring.

That was good to hear Cody, i had a feeling they would be ac, i have some good rectifiers, and rectifying diodes to make my own bridge.
About alternators, i wonder if those magnets from microwave owens would fit in the rotor? Seem’s they wold be good, strong and with a hole in them (for the axle).

I think it’s more of the luck of the draw. I like to grab all the bad speakers from work to scrounge the magnets from them.
