Do you remember the discussion at my blog about a Backpack unit that could be used to generate power? Weblink to Backpack: http://trewmte.blogspot.com/2006/11/electricity-generator-in-your-backpack.html

Well another invention has come along that I like that has helped in health cases in countries where no mains electricity power supply is available, called the 'WE CARE Solar Suitcase'. It is no wonder it has won an award. I can see other potential uses for this product to keep equipment charged and test rigs running when out performing site surveys and field tests.
