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.
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.
In the contacting stage, the DAC system transports atmospheric air containing CO 2 to the equipment using large-scale fans. Subsequently, in the CO 2 capture stage, CO 2 rapidly and effectively binds with liquid solvents in chemical reactors or solid sorbents in filters, which must possess binding energies equivalent to that of CO 2 .
If the energy is produced by the mass itself, as in a chemical rocket, the fuel value has to be /, where for the fuel value also the mass of the oxidizer has to be taken into account. A typical value is = 4.5 km/s, corresponding to a fuel value of 10.1 MJ/kg. The actual fuel value is higher, but much of the energy is lost as waste heat in the ...
Not every company's founders find themselves on a first-name basis with the local bomb squad, but then again not every company is Noya Labs, which wants to turn the roughly 2 million cooling ...

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).
