Limited-spectrum LEDs for indoor farming

Indoor farming reduces water wasted through evaporation and irrigation, reduces the need for pesticides, and allows for year-round food production. It also means that, in theory, food can be grown near or even in the cities in which most of it is consumed. 


Creative use of photovoltaics, architecture, and natural resources allows for indoor farming in the desert

"Aquapod" fish farming

Moveable, spherical fish farms could be the basis for more efficient aquaculture, which will be especially important as the oceans' natural fisheries decline. 

Grass-powered lawnmower

A robotic lawnmower powered by the grass it clips, and that can store the grass-power for later use. 

Insects for protein

An open-source bug farm farm could provide a way for people grow their own protein at a low financial AND low environmental cost.


A Dutch designer has developed a way to convert beetle wing casings—made casings—made mostly of chitin—into a kind of bioplastic. Given that a number of people are trying to develop ways to farm insects for food, chitin-based plastics could turn out to be a major part of manufacturing in the future.
