Pasi Vainikka: The next step in the food revolution

Creating food from 'thin air' sounds like a futuristic dream. But it's a future that's already arrived in the form of Solar Foods - Europe's first factory dedicated to making human food from electricity and air. What started with hydrogen oxidising microbes has resulted in Solein - a non-farmed yellowish protein product. After several years of lab experiments, production is underway in Vantaa, near the Finnish capital of Helsinki. The goal? To produce 160 tonnes of food a year. Solar Foods co-founder and chief executive Pasi Vainikka says Solein is a crucial next step in the food revolution.
