Hi,
I want to make an electricity generator based on water, which can produce lots of power (enough for a household), but it doesn't occupy a lot of space.
I've learned that a water-wheel based generator would have to be huge to produce 20 kWh, and I was wondering if instead of a water wheel there was a tube/cylinder through which water falls down onto a propeller/blade - would that be a more efficient way of producing electricity when it comes to size?
I saw a youtube video where a guy had such a cylinder/pipe of about 2 meters long, 20 cm in diameter, had a small-ish generator at the bottom from an electric bike or something, and was getting between 300 to 500 watts (he had different models)
I was wondering if you had a large tube, 1 meter in diameter, and 2 meters in height/length, could hold up to 1.5 tonnes of water, and it had a propeller/generator at the bottom, same size as the tube diameter.
Would that generator then use the entire 1.5 tonnes of water falling down to produce 14.7 kWh theoretical maximum?
If not, what would be a better design in terms of getting lots of power output (10-20 kWh) from a small space/area using water and gravity as the driving forces?
Thank you.
