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 ]

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).
When the company first started developing prototypes of its devices that attach to water coolers, the company's founders, Josh Santos and Daniel Cavero, did what all good founders do, they started ...
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.
Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.
At least Lachy has the decency to return Zeus watch — how kind! — while ratting out Dionysus in the process. Riddy and Orpheus make their way back to Earth, but before they get there, Riddy ...
The issue is still subject of numerous studies, and prompting academic argument. That's mainly because the "energy invested" critically depends on technology, methodology, and system boundary assumptions, resulting in a range from a maximum of 2000 kWh/m 2 of module area down to a minimum of 300 kWh/m 2 with a median value of 585 kWh/m 2 according to a meta-study from 2013.
