SUMMARY

The discussion centers on the feasibility of storing energy from lightning strikes. Participants highlight the immense voltage and short duration of lightning, making traditional storage methods like capacitors impractical due to their inability to handle such high energy levels without damage. Suggestions include using heating elements to convert the energy into heat or employing step-down transformers with capacitors to create oscillating circuits. Ultimately, while capturing lightning energy presents theoretical possibilities, practical implementation remains highly challenging and cost-ineffective.

PREREQUISITES
  • Understanding of electrical engineering principles, particularly high-voltage systems.
  • Familiarity with capacitor technology and its limitations in high-energy applications.
  • Knowledge of electromagnetic fields and the Poynting vector concept.
  • Basic concepts of energy conversion, particularly from electrical to thermal energy.
NEXT STEPS
  • Research high-voltage capacitor technology and its applications in energy storage.
  • Explore methods for converting electrical energy to thermal energy efficiently.
  • Investigate the Poynting vector and its implications for electromagnetic energy storage.
  • Study existing projects or experiments aimed at capturing and utilizing lightning energy.
USEFUL FOR

Electrical engineers, energy researchers, and innovators interested in renewable energy solutions and high-voltage applications.

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.
