I created a universal language for the deaf community

I lower your electricity bill

I heat your apartment with computing power

I created the Repair Café

I give people back their smiles

I co-created the world’s first chain of eco-hotels

My cooker lets nothing go to waste

I created a foldable electric car

I train rats to detect landmines

I use ducks instead of pesticides in my rice fields

I offer in-home refills for my own line of organic products

I build houses out of hemp concrete

I’m fighting Michael Jackson’s disease

I grow mushrooms from your coffee grounds

I designed an anti-rockfall textile

I put your computer to work for a good cause

I recycle plastic bags in New Delhi

I’m the first man to wear sanitary pads

I transform unsold newspapers into eco-bags.

I wash cars without water
