Been investigating the off-grid lighting market for both consumers and those businesses trying to reduce their power consumption or find alternatives during power outages. lightingafrica.org is a great place to start - the figures on how much the world wastes on fuel lamps is mind-boggling.
I bumped into Barefoot power at the recent SOCAP conference in Amsterdam. Stewart Craine gave me an excellent briefing on the challenges facing the industry and the ways they are keeping up competition from other countries eager to get into the solar lighting market. Word of mouth marketing on what's good and bad seems to be very very powerful, especially when people are investing hard earned cash in a product they hope will last. As well as being an entrpreneur, I was impressed what Barefoot has researched for the good of the industry as a whole. That's world class.
