Since I have been traveling all over Haiti to install internet by satellite, I was constantly confront with energy problems to juice the PC and modems. In one particular internet install in the south of Haiti, there was a foreigner who has a school for small children and adults and had a problem with the adults classes since during the day they had to work and by 5 pm it was to dark and there was no electricity. So I grab a piece of paper and design this roving inverteur that consists of:
One solar panel 100watts/ 2 batteries 220 amps 6 volts / 1 inverteur 250 watts / 2 energy saver lamps 25 watts / 2 wheels / 1 frame in metal.

He gave me a check of US$ 600 instantly. I went back to Port-au-prince and did built my first prototype and test it for 2 weeks and was so happy to see that rolling the unit to a sunny area from 8:00 am to 4:00 pm would juice 3 lamps 50 watts energy saver for the life of the batteries without city power or generator perfect for remote areas that could be easy to be transport to different places.
