Light a light bulb with no contact?

  • #1
Hi,

Is it possible to make a standard light bulb light without any physical contact to it (appart from support)?
I seem to remember seeing such an experiment, but can't remember the details.

Thanks

Japan has an official project to deploy orbiting solar panels and transfer the energy to earth with lasers. Currently around 40% efficiency they are spending tons of cash on getting that number higher so that it could compete cost wise with more traditional electricity generation.

Not that I recommend doing this, but if you can find a safe way to suspend a florescent light bulb near a high tension wire you will see it light up, even if the cathode is burnt out.

Or (I would not recommend it either :D) put the fluorescent bulb in a microwave oven..!!
I will light up.....although the metal parts might spark or arc off!!
(Its dangerous to put metals in a microwave oven. Dont try this, but those who have
tried had demonstrated that they will bulb will light up).

If you could induce a electromagnetic field and put it in the field, the light bulb may light up. There is also the other methods mentioned above, although I would not recommend the powerline or the microwave for obvious reasons.
