In this week's episode of RAZOR we find out about industrial insect protein factories, Formula E racing and new technologies being used to harvest atmospheric water.

By 2050 the global population is expected to reach almost 10 billion. Demand for food could rise by 60 percent, further impacting already depleted land and oceans. So where will all the extra food come from? It could be insects. 

Entocycle in London thinks one of the answers to boost our protein production could be farming the larvae of the black soldier fly. Next year, Entocycle will build what they hope is the first of many industrial insect protein factories in the UK. Each will contain 5-10 million flies on any given day. Emma Keeling investigates and tries the insects for herself.

Formula E is entering its 7th season, but can this fledgling, already multi-million dollar sport, match its petrol cousin for power and excitement? Motorsports have long been a way of testing new technologies for manufacturers. But Formula E is also changing perceptions of electric vehicles, which is of crucial importance for an industry that needs to reinvent itself to survive in our low-carbon future. RAZOR's Shini Somara talks to the Porsche Formula E Technical Project Lead.

Water scarcity affects 1.1 billion people around the world.  And the problem's getting worse with climate change. Atmospheric water is a possible solution. It's a resource equivalent to around 10 percent of all the freshwater found in all the lakes on Earth. But how do we get that water to the people who most need it? RAZOR's Shini Somara speaks to two scientists who have been working on some innovative techniques to pull water out of thin air.
