Cells and Factories
12 industrial processes keep civilisation running. Terraform has rebuilt each one to run directly on solar power and to ship anywhere, so any community with rock and sun can make its own materials.
12 core processes, engineered for solar.
A Cell is one industrial process rebuilt for solar power. It connects directly to the array, with no grid, fuel or operator. It starts with the sun and stops with the sun.

Same chemistry. Energy at a fraction of the cost.
Cells are designed for the lowest possible capital and operating cost. With energy this cheap, we use it freely wherever that lowers the cost of the product: simpler equipment, less heat recovery, daylight-only operation.
Industry pays today
3.6 cents for gas heat, 10 cents for grid power
Per kilowatt hour, at typical industrial prices.
Where solar is heading
Below 1 cent per kilowatt hour
Installed arrays at 3 cents per watt.

Energy per unit uses typical global figures. Today's prices assume coal at $5 per gigajoule for cement kilns, natural gas at $10 per gigajoule for lime and glass, and grid power at $100 per megawatt hour. Move the slider to see the solar column at different electricity prices; forecasts point to below 1 cent per kilowatt hour. Costs cover energy only.
Cells in series, plus 1 megawatt of solar.
A Resource Factory is a series of Cells plus one megawatt of solar. Feedstock goes in one end and a finished resource comes out the other. To make more, add Cells and add solar.
01
Sunlight arrives
Direct current from the array drives the Cells. No inverter, transformer or grid.
02
Cells convert
Each Cell runs one process. Add Cells and solar to add capacity.
03
Building Blocks are manufactured
Our own materials become buildings, 99% complete at dispatch.
04
Worlds are deployed
Terraform builds, owns and operates the environments.
In
Rock, sand, clay, limestone, ore, scrap, air, seawater
Out
Cement, lime, glass, brick, insulation, steel, silicon, hydrogen, fresh water

Prices in US dollars. Cement wins decisively against delivered cement in remote locations, commonly $200 to $400 a tonne. Ferrochrome, ferrosilicon, manganese alloy, silicon carbide, silicon and graphite all use the same two Cells; only the charge changes. Carbon dioxide is captured from air using the Factory's own lime.
