some tips on designing a solar panel that follows the sun. ?

We Answered:

Is this a solar tracking system?

Buy the solar array itself, you can't build these any more than you can build a transistor.

You basically need a large flat panel that tilts. Easiest is to use a motor and clock so the angle changes per time of day. Remember it has to be in a place facing south, with no shade and an unobstructed view of the sky from straight up down to the horizon to the south, or as close to the horizon as you can get. That's for a one axis tracking system. A more elaborate system will track SE to SW as the sun rises and sets, as well as NS for the changing seasons.

A system might track E to W or SE to SW automatically and have the NS setting done manually, as this setting need be changed only every week or so.

Help with tires for a solar panel car???

We Answered:

No need to reinvent the wheel. Bicycle tires provide what you want - low drag. Some claim to reduce the drag of spokes by using three to five solid supports. Some claim to reduce drag by covering the spokes with a flat sheet - on both sides of the wheel.

the environmental impact on the construction, use, and disposal of wind turbines? and solar panels?

We Answered:

No more than the construction of any other power plant, however the use will have far less impact.
