Given the very little info available on their site (www.perendev.co.za), I would strongly suggest filling the "Information request form" first. This is from their website:
"We have decided to produce the magnetic motor unit on a small scale for selected clients to test these units and to give us continual feedback. We are sending units to Europe, America and Australia. The 6 kw output unit is approximately 37" wide by 37" long by 50" high. We will be beta testing other sizes and outputs as well.
At this time, beta testers will be expected to cover the cost of manufacturing, shipping, installation, and testing. This will be under terms of a lease arrangement, with eventual option to buy, and will be in the range of $5,000 to $10,000 USD for the 6 kw unit."...more at: href=http://www.perendev.co.za/order/beta.htm>http://www.perendev.co.za/order/beta.htm
