"Hi, my name is Phillip, I am the CEO Opibus and we build electric vehicle and electric motorbikes."

FILIP LOVSTROM CO-FOUNDER, OPIBUS "Conceptually it is really simple, it has a motor in the rear wheel, it has batteries under this covers and a control unit here Your charging time comes to about 20 seconds because that is how long it takes to remove your battery and put another one in. Buying a normal petrol bike for 120,000 and then downing 500 shillings per day on fuel or buying a flex bike for 120,000 and spending 200 shillings a day."

"Hello, my name is Martin Ndoungtio, we build Aquaponic systems."

MARTINO NDOUNGTIO UN HABITAT "Aquaponic is a method of agriculture that uses recirculating water from a fish tank and the nutrients produced from the fish to feed the plants and then it gets filtered by the plants and falls back to where the fish are. In the case of lettuce, they tend to take 3 months from seedlings to a plant whereas when grown by aquaponic system they take about 6 weeks."

"I am Vincent Kitio, chief of the urban energy unit at UN habitat."
