If somebody already invented it you dont have to
there are loads of existing technologies out there that could be used in developing countries
the key is giving people the skills to produce things themselves..using the resources they have available
its easy to teach people to build turbines to produce power from readily available scrap ...that power can be used for lighting,to run low power computers/electrical appliances and to produce hydrogen gas via electrolysis of water....hydrogen can be used as a fuel to cook with and provide heat......simple technologies like this can give people access to power in the remotest of locations
producing power directly gives people a real idea of the true value of the earths resources
the average human would be able to produce about 100 watts of power if pedalling a bicycle powered alternator
that means cycling for ten hours to produce 1 unit of electricity....if we in the west had to produce our electricity ourselves rather than burning our fossil fuel reserves our consumption habits woud be vastly different.....
