This doesn't make any sense. It costs (according to the article) $38US to produce about 18W of electricity, a little over $2/W. I'm currently buying solar panels from China for $1.85/W US in small quantities, and they generally throw in the charge controllers as well. The article also implies that the hair needs to be replaced at some regular interval. Hardly newsworthy.

Where do you get your panels? http://www.wholesalesolar.com/solar-panels.html http://www.wholesalesolar.com/solar-panels.html lists prices from about US$3 to about US$10 per watt for panels in the 100-200W range and nothing below 100W, and http://www.solarbuzz.com/Moduleprices.htm http://www.solarbuzz.com/Moduleprices.htm has this lovely graph by month up in the US$4.40 range. I see http://www.ecobusinesslinks.com/solar_panels.htm http://www.ecobusinesslinks.com/solar_panels.htm lists some panels for US$1.85 per watt, but the discrepancy is worrying.

  Direct from the manufacturers and/or their factory reps. This is for panels in the 50-100W range.

    Just curious. What do you use your panels for? Personal use or do you build stuff to sell.

    Which manufacturers, and what kind of quantities do you have to buy in?

Well, you expect the prototype to be more expensive. This should be trivially easy to test.

  I found a second example on youtube last night. http://offgridissues.com/site/off-grid-energy/31-off-grid-energy/116-solar-hair-energy-second-example-found http://offgridissues.com/site/off-grid-energy/31-off-grid-en... I am going to test this soon, see for myself , would love it to be true.
