The Beehive: One part tractor, one part bus, two parts tiller and electricity generator... One cool machine for rural farmers.

This innovative tractor is designer JJ Hwang's concept of how modular vehicles could solve several problems at once for rural farmers.

His goals were to make something versatile, which would address transport needs of farm workers (over bad roads), serve as a platform for efficiently moving materials of varying size and weight, serve as a normal and walking tractor/tiller, and also provide a source of power generation for remote water pumping or household use when the electricity drops out.

It's a pretty neat concept, I'd be interested to see if something like this could be made affordably for rural farmers in developing countries...
