This heats hydrogen gas inside the engine which expands.

Not exact matches

This makes possible the conversion of solar energy into chemical energy that is stored as hydrogen gas formed inside the BPEC cell.

Hydrogen atoms which diffuse inside the cages only bond weakly to them, so the gas can be recovered simply by heating the material slightly.

Conventional approaches to compact hydrogen storage — compressing the gas to up to 10,000 pounds per square inch (psi) or cooling it down to cryogenic temperatures so that it liquefies (around 252 degrees Celsius)-- can attain only about half the energy density needed to fit enough fuel inside something the size of a gas tank.

The expanding shock front will heat and stir up the material of the Galaxy as it spreads outward, encouraging the mixing of heavy elements made inside stars with clouds of hydrogen gas in interstellar space, and influencing the evolution of the Galaxy as a whole.

Methane, the carbon - hydrogen compound that is the main component of natural gas and cow flatulence, gets trapped inside crystalline cages of frozen water in the muddy ocean bottom.

But the greatest damage to the complex, and the greatest release of radiation, may have been caused by explosions of hydrogen gas that built up inside some of the reactors.

As synthesized ZIF - 8 is a highly porous material composed of a number of micro-pores of 0.34 nm and 1.16 nm, hydrogen gas with a kinetic diameter of 0.289 nm can easily penetrate inside the ZIF - 8 membrane, while large molecules (> 0.34 nm) are effectively screened by the MOF filter.

The nebula's insides, which appear mushy and red in this view, are made up primarily of ionized gas, while the outer green shell is cooler, consisting of glowing hydrogen molecules.

The non-flammable helium inside the ship also provides a perfect environment in which to store hydrogen fuel containers that can provide hydrogen not as a lifting gas (as was used in the Hindenburg) but as a fuel for either a fuel cell propulsion system or simply to burn in conventional internal combustion propulsion engines.
