This question was posted in CE Conference by CEan - amitaries17

Anyone?
@ashuashi • 11 Mar, 2009 Seems an interesting one. Did any one answer it?
@Differential • 12 Mar, 2009 I guess I've not understood the question. You have been given a 100 watt bulb, which you are supposed to glow without connecting to electricity source. Right?
@terenasstand • 12 Mar, 2009 i don't think i understand this question.you want to glow the 100 watt bulb without any wire? where is the source? where is the closed circuit?
@Kaustubh Katdare • 12 Mar, 2009 I vaguely remember, we've had a discussion on wireless distribution of electricity. However the topic is interesting!
@durga ch • 12 Mar, 2009 sorry guys, I know any one can WIKI but i just took intiative.

check here -https://en.wikipedia.org/wiki/Wireless_electricity
@gohm • 12 Mar, 2009 Yeah, you do not need wire. There are many many conductive materials out there. yes, a lot of them are not very efficient conductors. Even your body will work if you are holding it. There's an old sideshow trick where someone sits on a table and shoots electric bolts via a generator from their hands and lights up bulbs.
@shalini_goel14 • 12 Mar, 2009 I am not sure but can solar energy be used here? 😕

How about becoming a new edison who invent -"A solar bulb" 😁

Haha, Shalini, I think Nikola Tesla rolled over his grave at the mention of edison 😛
@Saandeep Sreerambatla • 12 Mar, 2009 i think we can make a bulb glow by using a closed circuit and passing power as an EMF.
Material which conduct will make the bulb glow

@rammy_233 • 13 Mar, 2009 Hi ...
I am the one who is verymuch interested in "Wireless Transmission of Power" .....

I think... recent development in this regards is a 60 W of power is been transmitted to a distance of about 1 mtr...

let me know if there is any further development....?
@slipfriction • 13 Mar, 2009 Hey my first post! I know how to make a 100watt bulb (fluorescent) glow without wire, put it against a plasma ball. How it works, I don't know, it some sort of phenomenon. Here's a video I found, YouTube - Plasma ball and flourescent bulb phenomenon - hope you found this helpful 😀
@sauravgoswami • 14 Mar, 2009 100watts is too much power of-course does the questions means wireless glowing of bulb with the source at a distance or it should be just wire-free!!!
@Ernesha • 15 Mar, 2009 Wireless energy transfer - Wikipedia, the free encyclopedia

refer to this site 😛
@Ashraf HZ • 15 Mar, 2009 I tell you what, why don't we try doing a simple EMF experiment? Generate lets say.. 1W of transmit power through a dipole antenna at 2.4 GHz, get another dipole antenna and hook it up to a receiving circuit containing an LED. The usually just require 60mA of current. If it lights up, we'll have successfully performed "wireless" electrical transmission.. even if it is highly inefficient 😉

Though, trying to transmit 100W worth will get you intro trouble with authorities, if it hasn't fried your organs yet.
@gohm • 15 Mar, 2009 Has anyone built a Tesla coil? I've built a small unit way back when. With the proper skills and equipment, it is a simple foray into generation and exploring wireless transmission.
@sauravgoswami • 16 Mar, 2009 but tesla coils has its limitations too..........since tesla days
@gohm • 16 Mar, 2009 true, however Tesla was working on power tramsmission as he believed all power could be transmitted wirelessly. He built a huge coil unit until funding ran out.
@sauravgoswami • 17 Mar, 2009 well still many are working on his principle but no takers for them,since they are considered very dangerous and increses the chance of accidents!!!
@Pluto • 18 Mar, 2009 In answer to your question of lighting a bulb without wires, I believe it’s all to do with the inductive field surrounding AC high-tension transmission wires. I must state at this point that nobody should try this, as it is extremely dangerous. Hold a fluorescent tube (100w fine) near a phase of one of the conductors and the bulb will glow, the best results are seen on >132KV but you can get results on 33KV.

Hope this answers your question

@ashuashi • 18 Mar, 2009 Agree to Pluto.

I have also heard that in some villages in India, where high tension lines pass through, people try to install bulbs near these which glow & provide them light. Hence, you do not have to pay for the electricity consumption. ;-)

It also requires a distance to be maintained, else the bulb get fused or blasts. :sshhh:

I have heard about that too.
@aj_onduty • 28 Aug, 2010 One thing, I was toying with this question and I came out with a crazy answer. This is just stupid, but I thought in another way, in a simple way, simple and stupid enough.

The question is to glow a 100 watt bulb without a wire. I stressed myself on the word "wire". Wire is a shape of a material, it is not an independent material. A conductor can take shape of a wire, a block, a sheet, a pipe etc. Cant we use conductors in any other shape???
Please don't laugh, but I couldn't think of wireless electricity or solar energy. I just thought about it in a simple way.
What do you think?
