1. This is me back in the late 70's with my all electric "CityCar." It had a range of about 40 miles and a top speed of 40 mph. I use to drive it back and forth to the college where I taught. There was no where to plug in the car at the apartments where I lived, so I had to plug it in at the college. I had a few people ask why couldn't I install a wind generator on the top, so that as I drove, the wind could charge the battery. What's wrong with that idea? |

#2: There's been a lot of talk about hydrogen as a fuel for cars. Hydrogen has more energy per pound than any other fuel. (except nuclear). When hydrogen is consumed, the only product is water, so it's very good to the environment. The plan is to use "fuelcells," which are batteries that produce electricity from hydrogen. So cars would have electric motors powered by hydrogen. I think it's a good idea, but I wanted to hear what my favorite car experts think. They are Tom and Ray who host the CarTalk radio program. Both are MIT (Massachusetts Institute of Technology) graduates and one was a professor there. One owns a car repair facility and both are experts with cars. Also, they are extremely witty and funny. Visit this link to their site and report on the (3) problems they see with hydrogen powered fuelcells at this time. |

#3: In the picture at the right, the heart,
the middle sphere, and the metal globe all produce electrical sparks.The
left two produce sparks in enclosed glass so that's not problem. The right
one however, produces sparks in the open. (Yes, it smarts a little if
you touch it). The device is called a Van de Graff generator. I've had
this one for over 25 years. I remember playing with it and after awhile
feeling dizzy and nauseated. The reason was these sparks causes oxygen
in the air to combine with itself to form what compound?
