Follow up on the solar powered scooter – With Don approaching 1,000 solar-powered miles (he has 932 and counting), Don’s scooter seems to still be going strong. In fact, it has been five months since Don last had to charge it. In those five months, Don has been driving his scooter almost every day going around 11 miles on the average day. By occasionally giving his scooter a day off, he is able to make sure that his scooter always has a charge. Link.
