Master Roda , I have a question for you. Are you drawing down an air vessel into water under harnessed power , when the power is available , and then letting the buoyancy power a generator as it tries to float up?
If so it is a clever way to harness energy , I like your thinking, that is if I got it right. Storing surplus energy to be used when it is most needed is what everybody strives to do. I applaud your thinking. That is where inventions come from.
We could winch a 1956 Buick up into the air when the wind is blowing or the sun is shining. The energy could be released later as the 1956 Buick descends to the ground. It could spin a generator at high speed. Until the Buick is back on the ground.
There are no shortcuts to storing energy. Never have been. We could use wind or solar power to pump water uphill , and then let it drive a generator at night to power our needs. Same thing. An Old Buick on a winch has the same power as water pumped behind a dam or a floating vessel submerged in water. They all equal out in the end. Except the Buick under a tripod in the front yard gets the most attention. Some bylaw officer will be quick to tell you to get rid of the eyesore. So will all the greens. They are all lost people trying to tell us about energy.
One of the best forms of energy is a gallon of Gasoline. Oil is a commodity. Better than money or gold. To have ownership in this type of energy is most clever. All the dollars will decline in the future. Oil will be the valuable commodity. Second only to a bag of potatoes. Read carefully what I say.
I encourage your inventive mind Master Roda, I like your microphone - speaker thoughts , sounds good to me , I know nothing about music. Thanks
