I use nature to play turntables

We shine a green light on factory emissions

I take the elderly for a ride on rickshaws

My refrigerator works without electricity

My works exist in harmony with the natural world

I created the Children’s Republic to keep kids off the streets.

I opened an arts school for vulnerable children

I created a universal language for the deaf community

I purify water with solar energy

I harvest thistles to make bioplastic

I recycle plastic bags in New Delhi

I created the world's simplest toilets

We started Homeless Man of the Year

I transform milk bottles into designer lighting

We transformed a bunker into a hotel

I capture CO2 with micro-algae

Our bank lends buffaloes

I install air-conditioning systems above your head

I use dogs to sniff out prostate cancer

My radio show is run by crazy people
