Thanks. There are quite a few of these videos and by others as well on YOTUBE.

Hello, I am new here and several of us have a few questions. We have seen several video's like this.

1. Are these actually powering a bulb?

2. How long would last if never stopped?

3. Any fire danger?

4. I have a retrieving that says it will lift 800 lbs.

5. Any danger of doing the same thing with the retrieving magnet?

6. How big a light will it power?

Thanks for looking. I am retired and have some kids asking me. I wonder also.
