Dear richardlennox,

thanks a lot for your submission and first draft of your idea.

• I like to see your unconventional thinking and brainstorming

• Can you explain the system of your main idea in some more detail? I do not understand how the hot air will create underpressure in the closed well.

• I am not sure if a kite will work there. Do you have some information about the wind situation in Bihar? Would your idea work without a kite as well?

Thrilled to see your next steps.

Yours Jesko

Dear Richardlennox,

It's a parachute configured to be a kite :) If it were balloon then it would never fall, and wind-caused movements would give some energy, I like it, but is it strong enough to extract water from the ground?

Cheers, Kris

Hi, yes, some calculations would be interesting. How would you pull out the water if you only have a small bore hole ? Also, several people (maybe 500 kg) isn't a whole lot of water, only 500 l.

This idea has merit.

Imagine

1. A suitably sized blimp, filled with hydrogen
2. moored to the ground above the farmers field
3. The higher the blimps altitude the greater and more consistent would be the wind energy available.
4. An electricity generating windmill turbine and/ or solar panels are suspended beneath the blimp. Or indeed its surface is coated with the new solar films coming on to the market.
5. Electricity is fed to the ground through a cable to a standard elecetric motor and water pump.

I think this design would eliminate to some extent the variability of wind/sun available to provide consistency.

If the farmer were to dig a storage tank or better still support one in a frame/earth bank above the crops to be irrigated, the blimp could remain in place all day pumping water.

The blimp could be deflated, packed away and re-inflated the next.

It would work.

No so suitable if you read that there is no wind in that area

Good idea. Check NASA Kite pages (aerodynamics pages) for some of the math. I know that Google' Makani uses low wind to get the kite into the upper atmosphere to utilize 'Laddermill Theory' (figure eights for speed) to get energy. Wind is available- just way up. In NC, US it's a little over 100ft to a reasonably steady 10mph wind(very low pumping) and further up to get to useable. The figure eights make electricity production viable. A 'kid' could fly a kite all day to water fields ....lol

A black hot air balloon as power source, rising and falling through day and night. I like the way you think. It's going to have to be pretty big, but it might work if you can find a cheap and strong enough material to make it out of.

idea needs development

tnteresting

Never thoght this can also produce energy but needs experiments and tests to be carried out before brought in use..!!!

no potential of wind energy in bihar

I think this idea has huge potential. If the kite can be automated! But is there wind in Bihar?

Maybe that's the reason nobody else shows wind based systems?

zero wind potential in bihar

not very promising concept
