This is my latest attempt at taking Ed Lenz's excellent design and 'simplicating' it to make it mass production suitable. I have chosen corflute plastic for its light weight, low price and transportability. Center shaft is two aluminium tubes with a Maglev bearing (two neodymium magnets). This design could be shipped flat packed and assembled by the user on site. Need to compete with solar price of around $5 per watt.
looks like it would have very little drag
