01
Catch the sun as current
A field keeps under one percent of incident sunlight as food. A commercial panel keeps more than twenty percent as electricity.
Science
How electricity becomes food.
From a solar panel to acetate or hydrogen, then to yeast, algae, or Solein. The electro-agriculture path, with the limits New Scientist actually reported.
02
Make a molecule a cell can eat
Electrolysis of water makes hydrogen. Electrolysis of CO₂ makes acetate. Acetate dissolves. Hydrogen barely does.
03
Grow the eater in a tank
Yeast, algae, or bacteria turn that molecule into protein or fat. Modified plants, via Nolux, may do it without a lamp.
04
Leave the acre where it is
Renewable power takes calories off the ledger of land clearing. Fossil power only moves the smoke indoors.
What the sun is actually for

Relative to a field
Hydrogen
Hydrogen, then a microbe
Split water with renewable electricity. Feed the hydrogen, plus captured CO₂, to bacteria in a tank. Harvest a protein-rich biomass.
Acetate
Acetate, then anything that eats it
Electrolyze CO₂ into acetate, a molecule that dissolves easily in water. Yeast, algae, or genetically tuned plants grow on it in the dark.
Methane
Gas fermentation, already at tonne scale
Microbes have already been grown on methane for animal feed. The climate case only holds if that gas stops coming from fossils.
Fats
Syngas into fat
Hydrogen and carbon monoxide can be turned into edible fats — the calories plants are worst at making on purpose.
Cells
The plant, without the field
Grow the cells that make chocolate, coffee, or oil in a vat, and skip the tree, the season, and the cleared forest.
