RFC Electric Greenhouses 1GW = 20 SQMLs
Large scale greenhouses can be used to replace power stations for electrical power generation. The plants grown inside the greenhouse are pulverised and desiccated before use as the fuel source for the electrical generation. The heat and the CO2 released in the combustion process are captured (and recaptured) within the gas impermable greenhouse, providing a huge acceleration in plant growth. A jungle in a bottle. To achieve reliable 24h/365d power delivery to the national grid the greenhouse must therefore use the ground as very large thermal store and have an appropriate lighting system.
Pros
Reliable power delivery 24h/365d unlike PV and wind. Good as they are.
No CO2 released (handy for carbon neutrality by 2030) Gas impermable.
No H20 released (handy for a deserts, but Brownfield and Opencast site with broken ecosystems can be used.
No fossil fuels usage
A greenhouse reliable technology that has been available for use for 120 years.
Power for 300,000 homes.
Cons
50 square kilometres/ 20 square miles produces to a gigawatt. 4.5*4.5 mls
or 100mw = 2sq miles.
Cost irrelevant, carbon neutral by 2030. Shovel ready in two months, if taken seriously.
