I created a universal language for the deaf community

I invented a shrimp-based bioplastic

I created the world's simplest toilets

I recharge my phone while getting fit

I created a hospital for paralysed people like me

My technology reduces maritime shipping emissions

Learn to praise yourself

These wood bricks don't need nails, screws, or glue

I reveal the secret life of water

Coral reefs have a future because of my invention

I give a new life to used fur coats

I install air-conditioning systems above your head

I construct photovoltaic greenhouses to combine green energy with organic farming

I use oyster shells to make paint.

I fill up my tank with what you throw away

I offer a roof to millions of people

I created the Barefoot College

I give people back their smiles

I make cardboard furniture

I use plants to clean toxic soil
