    Energy Lightning
Click For Summary
Storing energy from lightning strikes presents significant challenges due to the extremely high voltage and short duration of the discharge. Capacitors likely cannot handle the initial shock without breaking down, and using resistors to lower voltage would result in excessive heat loss. Some participants suggest alternative methods, such as using the energy to heat water or employing step-down transformers to create oscillating currents. However, the consensus is that while lightning contains high voltage, it ultimately has low energy yield for practical storage, making it an inefficient energy source. Overall, capturing and utilizing lightning energy remains largely impractical and cost-ineffective.

How about a blimp grounded by a long copper tether? :D

XD nice I think that's a good idea.

I know that you can store lightning theoreticaly, as i have worked on a theory for over ten years, and at the time of conception there were no such thing as carbon nanotube batteries without which the rest of my designed system would be very difficult to store large quantitys of charge in a short space of time.

P.S i am waiting for a company to take on this development as it is theory, that i believe could be tested and trialed at low cost before production.

My first intuition would say that if you would try to charge a capacitor with a bolt of lightning, you'd just melt your capacitor. Remember, we're talking about a voltage high enough to discharge through at least tens of meters of air, so I highly doubt there is a man-made capacitor that can take these voltages without breaking.

Contrary to what most here think about capacitors, IMO, they can be used.

If anyone has seen very large and high performance Van De Graaf Generators(alternately, Pelletron machines) used to simulate lightning for EMP - Proof - testing equipment, they are also in many ways, a capacitor by their nature of storing electrical charge. The sphere as plate of a capacitor and air as dielectric.

I believe such capacitor designed to capture lightning charge would look not much different from a very large Van De Graaf Generator. Also using air as dielectric and using alternating bands of conductive rings or plates (with rounded edges) between the main plates to improve efficiency (reduce corona discharge).

Funnily enough i have a side element to my system just as you describe. It is a large pre chamber if used, to slow the intial shock of the large emf and allow a few more milliseconds of charge decay which i still have a few issues with. i was toying with the idea of using different gasses to further the decay, but there are system impedance issues that are within tight parameters.

In that case...
PLEASE FOR THE LOVE OF GOD...
Spell lightning correctly.
Please, are you in college? postgrad? professor?
Then PLEASE spell Lightning right.
and Quantities as well.
