Re: Solar car - A possibility

<t>The world record for WiFi is about 200 miles between mountaintops using large (10 meter) highly-directional antennas.  You can get wireless USB dongles that come with directional antennas that will easily get you well over a mile in unobstructed range, probably much more.  The antennas' beamwidth...
