390 PWh/year electricity for CO2 from the atmosphere

Reduce the CO2 content with Power to Carbon, generate fuels with Power to Liquid and use CO2 for indoor plant cultivation to replace large-scale agriculture.






390 PWh/year electricity for CO2 from the atmosphere Reduce the CO2 content with Power to Carbon, generate fuels with Power to Liquid and use CO2 for indoor plant cultivation to replace large-scale agriculture.

The first task of filtering CO2 from the atmosphere is already in the logo of this website: to process 50 billion tons of CO2 per year into useful carbon products. For this purpose, 300 PWh per year are planned.

Point 2 is also clear, airplanes for distances over 2,000 km will hardly be possible with batteries, as will ships for distances over 2,000 km. Filling the winter gap far from the equator with power to methanol and combined cycle power plants. For this purpose, 30 PWh for 5 Gt CO2 per year are planned.

  Surprise food production


It's getting drier. Large-scale agriculture requires vast quantities of chemicals to produce food in a highly inefficient way. Aeroponic Vertical Farming in a glasshouse creates competition with large-scale agriculture.

Plants need CO2 to grow. Plants take CO2 from the air and split it into C and O, the photosynthesis. Intensive growth in small rooms requires about a hundred times more air exchange than in living rooms.

In very hot dry areas, due to the climate catastrophe there will be a lot of very hot dry areas, a lot of water evaporates during the air exchange. Oh, there is far too little of that in very hot dry areas.

One could dehumidify the exhaust air from the greenhouse to recover the evaporated water. But with the enormous amount of exhaust air, this requires an incredible amount of electricity. The other method is almost no air exchange in the greenhouse and you bring CO2 directly into the greenhouse. With only 1.5 KWh/kg CO2, this method is more than one order of magnitude cheaper than air exchange with moisture recovery.

1.67 kg of CO2 per kg of plant growth is required, which would be 2.5 kWh for filtering from the air. At 700 to 800 ppm CO2, plants grow 30% faster.

This will require 60 PWh per year, which will filter 40 Gt CO2 from the atmosphere and allow 24 Gt of plant growth in Aeroponic Vertical Gardening greenhouses. This type of plant cultivation gets by with 98% less water.

A logical consequence of land will become more expensive, water will become more expensive, solar power will become much cheaper. An essential requirement for the 1000 m² per inhabitant society.

-250% CO2 emission until 350 ppm are reached again -250% CO2 emission until 350 ppm are reached again
Less CO2 emission is much too little, even zero emission is insufficient. Only a planet renovation with large-scale CO2 filtering and splitting from the atmosphere will help.


Filtering and splitting CO2 from the atmosphere Filtering and splitting CO2 from the atmosphere
Due to their enormous space and water requirements, plants are unsuitable for the necessary reduction of the CO2 content in the atmosphere. There is no room for 37 million km² of growing forest.


Carbon fiber becomes standard material for construction Carbon fiber becomes standard material for construction
If we filter the 33.1 Gt CO2 emission of 2019 from the atmosphere and split it into C and O, we get 9 billion tons of carbon. What to do with it?

Constantly contradicting itself, the IPCC 2021 report adheres to the completely inadequate “net zero emissions” target. This can only be thinking prohibitions.


Green dogmatism and the destruction of the German photovoltaic industry Green dogmatism and the destruction of the German photovoltaic industry
How the dogma “the demand for electricity will decrease” led to extremely wrong targets, which led to the destruction of the German photovoltaic industry in 2013.


Why Germany is failing in the energy transition Why Germany is failing in the energy transition
In the first decade of the new millennium, Germany was the great role model in the energy transition, why, on the other hand, the current EEG policy leads to disaster.

Hit hard by the breakdown in tourism caused by COVID-19, the higher price of oil comes as the next blow. The serious failures of the industrialized countries.


Destructive cult prevents functional energy transition Destructive cult prevents functional energy transition
A horror novel about a world without renewable energy and recycling delayed a workable energy transition and thus effective climate protection by decades.


Functional energy transition vs. German energy transition Functional energy transition vs. German energy transition
We have to denounce very hard the grotesque German energy transition in order to turn all the enemies of this grotesque into fans of a functional energy transition.


Paradigm changes – Profitability transitions – Culture shocks
We can neither achieve energy transition nor stop climate change if we do not constantly review all parameters and abandon unsuitable views.
