Firstly, careful design is needed to make hydrogen combustion stable, as hydrogen flame propagation velocity is very high — up to seven times faster than natural gas, which may lead to flame ...

A balloon filled with helium and one filled with hydrogen are ignited. Hydrogen provides a loud explosion and flame. He(g) + O 2 (g) → N.R. Light the candle on the end of the yardstick and lower the ...

Say hello to hydrogen combustion. These vehicles use the same ... of reaching a higher thermal efficiency thanks to a higher flame speed than gasoline, allowing it to achieve efficiencies of ...

Fire is arguably humanity's earliest discovery. It was pivotal in advancing society—underpinning many of humanity's most ...

NASA and a startup called FGC Plasma Solutions are developing a technology that could completely change how jet engines work.

NASA is not choosing hydrogen, electricity, or nuclear fusion as a desired fuel choice but exploring plasma-assisted ...
