Need of a portable solution?

This picture depicts how some can go an extra mile to harbor that load somewhere in the rural areas of sub Sahara Africa where access to electricity, clean water and appropriate shelter is non-existent. Business ideas and humanitarian hands can co-exist well here. Do have an idea on cheap sources of power such as solar, LED bulbs, Stoves etc? Do you wish to make a small contribution to climate change? You can make a big change for yourself and in others and that is why are highly welcome.
