A revolutionary energy source

Produced by atoms. Secured by gravity.

A Generation IV Development


After oil, gas and coal: the nuclear age! The adjoining diagram compares the efficiency of different energy sources using the EROI: Energy Returned on Investment — the factor by which human work is amplified through technology. Due to the low energy flux density of solar irradiation and wind, renewables are not suitable as a main energy source for an industrial society.

The Dual Fluid Reactor was designed by the Institute for Solid-State Nuclear Physics with maximum efficiency in mind. It enables humanity to increase the standard of living globally while quitting fossil burning.

Concentrated energy sources affect nature less than diffuse ones. The more compact we build our power plants and factories, the more space remains for plants and animals.

The illustration shows the land area needed to supply Berlin, the German capital, with electricity (1.5 gigawatts). The DFR needs neither mines nor pumped storage: It creates energy on demand for centuries from nuclear waste and depleted uranium — that way, seven, eight or even ten billion people can enjoy an European standard of living, and black stork and wildcat still find suitable retreat areas.

What if something goes wrong? Have Chernobyl and Fukushima not shown that nuclear power harbors uncalculable risks?

Traditional nuclear plants employ multiple safety layers to minimize risks. But these mechanisms can fail.

The DFR does not need external safety equipment. It protects itself — using gravity! If the reactor overheats, melt plugs dissolve and the fuel liquid streams into storage tanks.

The DFR is protected by the laws of nature!

To gold cling all… how much will it cost?

The DFR is extremely compact. Only small amounts of material are needed for construction. Inherent safety makes complicated, layered protection equipment obsolete. Thus, the investment costs are comparable to those of a coal-fired power plant! Unlike fossil burners, the DFR consumes only minuscule amounts of fuel. Thus, electricity prices below 1 cent per kWh and synthetic fuels, produced by nuclear process heat, which are competitive with gasoline and Diesel become possible.

Clean energy cheaper than lignite need not remain in the realm of science fiction!

What about nuclear waste?

The DFR does not create long-lived waste.

It destroys the waste of old nuclear plants. Light-water reactors utilize less than 1% of the heat content of natural uranium — the DFR turns the remaining 99% into usable energy. Only fission products remain, the radioactivity of which falls below that of natural uranium after 300 years.

The reprocessing unit extracts the fission products sorted by atomic weight: That way, valuable materials (e.g. for nuclear medicine) can be recovered. Waste is only waste if one wastes it! Recycling turns it into raw materials.

Energy Efficiency

EROI of more than 2000

The Dual-Fluid-Reactor’s EROI is higher than for any other energy source: around 2000.


Smallest Land Use

The DFR can provide up to 15 billion people with electricity – without devastating nature.


No need for external safety

The Dual-Fluid-Reactor is protected by one of the universe’ most powerful forces: gravity.

Investment Costs

Nuclear Waste Burning

DFR creates no long lived waste

The Dual-Fluid-Reactor doesn’t create long-lived waste.


High-Efficiency Turbogenerator

Frogs won’t turn red because there’s a DFR operating nearby! The higher a power plant’s operating temperature, the more efficiently can heat be converted into electricity — this means less heat dissipation to the environment. The DFR operates at 1000 °C, giving a thermal efficiency of 60%. Protecting the environment and resources.



Turbine heat loss at 250° C need not go to waste: suitable for seawater desalination. Californian draughts may soon be a footnote in history books.


Process Heat


Personal mobility without mineral oil? Nuclear process heat is your friend! DFRs enable cheap hydrazine production, which can be used in fuel cell cars, going twice the distance of gasoline cars for the same price.


Hydrogen Synthesis

If pure hydrogen is asked for — e.g. for steel production instead of coke —, the DFR is the best choice, too. Through the HOT-ELLY-Process or Sulphur-Iodine-Cycle, water can be dissociated for a reasonable price.


Medical Isotopes


In order to treat cancer or bone fractures, hospitals often use radioactive tracers. They show the doctors precisely, where to operate. With the DFR, radiotracers can be produced most economically.


Molybdenum Production

Technetium 99m is one of the most important tracers. It is created from the predecessor Molybdenum 99, which is produced in research reactors — complex and expensive. The DFR can help here: A single plant will output multiples of world demand, isotopically pure.
