Expert Profile: Dan Fink

Expertise:  Though my experience is mostly in the fields of electricity, magnetism, and physics, I have a broad science background. My career is in the field of alternative power sources -- solar, wind, water and battery power. But any questions about electricity, magnetism, energy conservation, power generation, electric motors, and even general physics are very welcome--especially from kids. They ask the best questions of all! I pride myself in answering science questions accurately, with ideas for SAFE, easy experiments that kids can perform by themselves--and that let them prove the answers to their own satisfaction. I think science should be fun, and available to everyone, regardless of age.

Experience in the area
I have volunteered in our local public schools for 5 years. I currently make presentations at our schools about electricity and magnetism, with a focus on solar, wind, water and other alternative power sources. I try to demonstrate at our schools how easy it is to make electricity, with simple devices using spinning magnets and coils of wire--powered by wind, water, bicycles, gerbils...etc. And of course solar panels! I am the webmaster of Otherpower.com, an alternative energy website. I have lived 10 miles from the nearest power pole for 11 years--I make all my own electricity from scratch with sun, wind and water.

Thanks -- and by the way, the scene that I think you mean was in "X-men," where the working material of the model was, I think, a form of sand w

2009-07-01  temperature and coke going flat Hi Briana -- The easiest way is to use balloons, and stretch them over the neck of a bottle of soda. Give the bottle a shake, and the balloon that inflates the most indicates the most CO2. This would...
2009-06-29  temperature and coke going flat Hi Briana -- Looks like you have this under control. Yes, temperature will affect the rate that the CO2 comes out of solution from the Coke and into the air. The warmer, the faster. For another variable...
2009-06-28  Question about negative ion generator experiment. Hi Steve, it's fine to ask in a followup, everything gets indexed. It sounds like that experiment was a water capacitor. It can store enough energy to knock you across the room with a shock! To understand...
2009-06-28  Electric Motors Hi Jessica -- Water is not a very good conductor of electricity, so it doesn't short out the motor electrically. However, try it in salt water (which is a conductor) and the result will be different...
2009-06-27  Question about negative ions. Hi Steve -=- Yes, you have it correct. Remember how I said that the closer you are to the high voltage of the ionizer, the stronger the electric field? When the field is strong enough, it's said that...
