Neither animal, nor plant - just protein and electricity, leading to... Electric Food. The ultimate sustainable meal

A startling article from George Monbiot this week, bringing us strange news that can answer our anxieties about how toxic our current forms of agriculture are, whether for animals or vegetables.

Consider electric food:

Could we go beyond even a plant-based diet? Could we go beyond agriculture itself? What if, instead of producing food from soil, we were to produce it from air? What if, instead of basing our nutrition on photosynthesis, we were to use electricity to fuel a process whose conversion of sunlight into food is 10 times more efficient?

This sounds like science fiction, but it is already approaching commercialisation. For the past year, a group of Finnish researchers has been producing food without either animals or plants. Their only ingredients are hydrogen-oxidising bacteria, electricity from solar panels, a small amount of water, carbon dioxide drawn from the air, nitrogen and trace quantities of minerals such as calcium, sodium, potassium and zinc. The food they have produced is 50% to 60% protein; the rest is carbohydrate and fat. They have started a company (Solar Foods) that seeks to open its first factory in 2021. This week it was selected as an incubation project by the European Space Agency.

They use electricity from solar panels to electrolyse water, producing hydrogen, which feeds bacteria that turn it back into water. Unlike other forms of microbial protein (such as Quorn), it requires no carbohydrate feedstock – in other words, no plants.There are plenty of questions to be answered, plenty of possible hurdles and constraints. But think of the possibilities. Agricultural commodities, currently using almost all the Earth’s fertile land area, could be shrunk into a few small pockets of infertile land. The potential for ecological restoration is astonishing. The potential for feeding the world, a question that has literally been keeping me awake at night, is just as electrifying.

…None of this means we can afford to relax and wait for an infant technology to save us. In the meantime, as urgent intermediate steps, we should switch to a plant-based diet and mobilise against the destruction of the living planet. You could start by joining the Extinction Rebellion movement, which launches today.

But if this works, it could help – alongside political mobilisation – to change almost everything. Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet. A new age of global hunger becomes less likely.

Crude and destructive technologies got us into this mess; refined technologies can help get us out of it.
