atmospheric water generatorIt would be cool to find a way to make money with extra PV.
Anymore ideas?
reminds me of this thread about using solar energy to remove humidity from wood with heat and airflow : https://diysolarforum.com/threads/modified-solar-wood-kiln.15387/I have a customer that drys lumber with his solar. Just has fans pushing air through the bundles.
curious if the fans run 24/7.I have a customer that drys lumber with his solar. Just has fans pushing air through the bundles.
Would a permanent magnet alternater improve these numbers? Not having to build a msgnetic field first?I have 3 x 2500gal rain harvest tanks in my yard. Each tank could weight 2,500gal * 8lb/gal = 20,000lbs or 10tons.
I did some calcs one time on the power I could generate if I raised a 10ton tank up 6ft in the air and then let it fall slowly (turning a generator) back to earth. The numbers came out to 100Wh or something really small. It's like turning a generator from rain water going down you're gutter - you can get 1-2w.
I'm just struck by the immense amount of mechanical power it takes to turn a generator - whether a propane engine, wind, water, or gravity - compared to panels that sit silently/still and generate a good bit of power.
The math was based on googling formulas for power based on gravity. The potential power reward for such an immense DIY effort to raise (store power) / lower (recover power) a 10ton tank 6 ft is so tiny that this kind of generator detail would not materially affect my view that it's wildly impractical.Would a permanent magnet alternater improve these numbers?

Use a windmill to lift the water to the upper tank when the wind is blowing. The rest of the time a 12v rv pump.On the other had it is quite (relatively) practical if you lift 60 or 600', not 6'. Not the entire tank at once, but the contents, through a pipe.
Somebody came up with that stupid idea of a construction crane stacking cargo container weights.
Total available watts from the crane not enough to be interesting. Pumped hydro the scale of a power plant makes more sense.
Probably round-trip efficiencies using motors and cables is likely better than water through pipes, but equipment cost and scale .
This is what will probably become the number one Global way to use and make money on excess PV power.Put an EV charger in your driveway. And sell the excess power. (If it can be done legally)
You have successfully compared a Briggs engine to an immense fusion reactor in the center of the solar system.I'm just struck by the immense amount of mechanical power it takes to turn a generator - whether a propane engine, wind, water, or gravity - compared to panels that sit silently/still and generate a good bit of power.
How do you like the harvest right? I have had my eye on one for several years. We have a garden and it would make it so easy to put up food for long term storage.Use the extra power to create some prep supplies? We run a Harvest Right Freeze Dyer - haven't measured it but it's 10-15kwh / 24hr-cycle. The food is reconstituted with water and a good number of items (eggs, hamburger, for example) are quite good after reconstitution.
Personally, I'd LOVE to build a 10,000kwh battery and store the summer excess for winter, but that would be on the order of 1Million+ 18650 cells
This guy has been storing solar energy in hydrogen for decades in NJ.Hydrogen can be safely used and stored:

well inshould hope they do.Nobody under the age of 40 probably even knows what the Hindenburg was..
wish this would be an economically and readily available optionThis guy has been storing solar energy in hydrogen for decades in NJ.
I remember learning about it back in elementary or high school (central PA) and watching a few documentaries on it since. It was a fascinating feat of engineering and shockingly charging reason for its demise. Born in 88, some of us young old folk still have it together.well inshould hope they do.
it is tought all over the world in history classes ( except the usa, as i never had it in middle or hogh school, which explain a lot of the issues currently going on there. )

No doubt they will know Helium !!Nobody under the age of 40 probably even knows what the Hindenburg was..
It was hydrogen, which is highly flammable.No doubt they will know Helium !!
