Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience in the area

I'm a physics professor, research in nuclear astrophysics. I teach physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science.

Education/Credentials

Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.

You are, of course, assuming that air resistance is the main resistance to a runner's motion. At those speeds, it would indeed be significant, but you're comparing using the assumption that at human speeds

Air won't charge up a vehicle much, though it is another charging (and discharging) mechanism. Air probably discharges the vehicle more than it charges it because it will carry excess charge from the
