I created a universal language for the deaf community

I trade your trash for organic food

I created a fabric from the lotus flower

My electric bike runs on hydrogen

I invented a machine to dye fabric with vegetable scraps

I heat your apartment with computing power

I created Clean Up Day

I make you laugh out loud

I stand up for men in skirts

Our drivers tackle some of Africa's toughest roads to save lives.

I fly with migrating birds

My radio show is run by crazy people

I put your computer to work for a good cause

I created a hospital for paralysed people like me

I created the world's first solar cycle path

I transform unsold newspapers into eco-bags.

I doubled green space by building a hotel

I turn your dance moves into kilowatts

I created a new recycled and recyclable material

I’m a guerrilla gardener
