The attendant wears a full hazmat suit due to the hazards of the hypergolic fuel hydrazine, here being loaded onto the MESSENGER space probe. A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other.
These gels are useful when filming scenes in which it is desired to give the illusion that someone is on fire. To do so, the gel is applied to an area of the body. Next, a fuel is placed on top of the gel. When ready to film the scene, the fuel is lit on fire. The gel insulates the person from the energy released from the burning fuel.
The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N 2 O 4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion ...
One example of RFC is solid oxide regenerative fuel cell. Solid oxide fuel cell operates at high temperatures with high fuel-to-electricity conversion ratios and it is a good candidate for high temperature electrolysis. [7] Less electricity is required for electrolysis process in solid oxide regenerative fuel cells (SORFC) due to high temperature.
The converter can use many diverse forms of fuel without the need for fuel-specific customization as seen in internal combustion engines, and can generate power from fuel combustion, solar irradiance, low grade waste heat from industry, or such other power generation systems as fuel cells, internal combustion engines, or turbines, because it ...
The AFRL began solicitations for contractors to develop a follow-on prototype to THOR in July 2021 called Mjölnir, named after Thor's hammer to keep the new system's name in the family. Mjölnir will incorporate improvements in capability, reliability, and manufacturing readiness to produce a deployable system that can be made in large numbers.

In July 2018, the company agreed to install a 200–400 kW fuel cell unit at the Southern Oil's biorefinery at Gladstone, Australia. [12] In July 2020, AFC Energy announced a collaboration with Extreme E to use its hydrogen fuel cell technology to enable its race fleet to be charged using zero emission energy. The by-product of utilizing these ...
