I created a universal language for the deaf community

I create fuel from algae

I created Neighbour Day

I fill up my tank with what you throw away

My cooker lets nothing go to waste

I change the lives of Africa's poorest farmers

I construct photovoltaic greenhouses to combine green energy with organic farming

The untouchables I help are no longer destined to clean human excrement

I turn water from your toilet into drinking water

I make soap from used cooking oil

I created a hospital for paralysed people like me

Come on over, my neighbour’s making dinner

My refrigerator works without electricity

My nets capture water from the clouds

I purify water with solar energy

I created the first medical Facebook

I stand up for men in skirts

My restaurant runs on hydroelectric energy

I created the world's simplest toilets

Trash from the sea is treasure for our art
