Prometheus Fuels is an American energy startup developing tools to filter atmospheric CO 2 using water, electricity, and nanotube membranes to produce commercially viable fuels. When powered by renewable electricity sources, e-fuels produced by such direct air capture methods do not contribute further emissions, making them carbon neutral . [ 1 ]
Robert L. McGinnis is an American scientist, [1] technology entrepreneur, and inventor who has founded a number of technology companies including Prometheus Fuels, [2] Mattershift [3] and Oasys Water.
Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
Electrofuels, also known as e-fuels, are a class of synthetic fuels which function as drop-in replacement fuels for internal combustion engines. They are manufactured using captured carbon dioxide or carbon monoxide, together with hydrogen obtained from water split . [ 1 ]
The V-2 rockets developed by Nazi Germany used LOX and ethyl alcohol. One of the main advantages of alcohol was its water content, which provided cooling in larger rocket engines. Petroleum-based fuels offered more power than alcohol, but standard gasoline and kerosene left too much soot and combustion by-products that could clog engine plumbing.
Alkaline fuel cell Alkaline fuel cell (AFC) also known as the Bacon fuel cell. Alloy An alloy is a solid solution or homogeneous mixture of two or more elements, at least one of which is a metal, which itself has metallic properties. Alternator An alternator is an electromechanical device that converts mechanical energy to alternating current ...
Prometheus is a backronym from the original French project designation PROMETHEE, standing for "Precursor Reusable Oxygen Methane cost Effective propulsion System", and for the Titan Prometheus, from Greek mythology, creator of humanity, and god of fire, known for giving fire to humanity in defiance of the gods.
HT-PEM fuel cell was developed in 1995 for operation at higher cell temperatures aiming at lower sensitivity of PEM fuel cells regarding impurities. [3] Thus HT-PEM fuel cell technology is one of the youngest fuel cell types and HT-PEM fuel cell systems are produced since the 21st century by several companies.
