Discussion Overview

The discussion revolves around the feasibility of storing energy from lightning strikes, exploring various methods and challenges associated with capturing and utilizing this energy. Participants consider both theoretical and practical aspects of energy storage, including the potential for using lightning energy in homes or other applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express skepticism about the practicality of charging capacitors with lightning energy due to the extreme voltages involved, which could damage components.
  • There is a suggestion that building a large capacitor or "laden jar" could theoretically store lightning energy, but practical implementation is questioned.
  • One participant notes that the short duration of lightning pulses may limit the amount of usable energy.
  • Another proposes that capturing static electricity from the atmosphere before a lightning discharge could be a more efficient method, although no specific device is suggested.
  • Theoretical discussions include the possibility of storing electromagnetic energy based on the properties of the Poynting vector, though its relevance to lightning energy is debated.
  • Some participants suggest alternative methods for utilizing lightning energy, such as converting it to heat or using transformers to manage the energy discharge.
  • Concerns are raised about the potential damage to electronic devices from lightning energy, drawing on experiences with high voltage systems.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of storing lightning energy, with multiple competing views and uncertainties remaining about practical methods and the amount of energy that could be captured.

Contextual Notes

Participants highlight limitations related to the high voltages and short durations of lightning strikes, as well as the challenges of designing components that can withstand such conditions. There is also a discussion about the assumptions underlying certain theoretical models, particularly in relation to fluid dynamics and electromagnetic fields.

Who May Find This Useful

This discussion may be of interest to individuals exploring energy storage technologies, electrical engineering, atmospheric physics, and those curious about innovative applications of natural phenomena.

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.
