As with any radical change to an existing technology, especially a jet engine, a large installed base of expertise together with lots of regulation mean it can be hard for a newcomer to make headway.
Secondly, if it enters a jet engine the intense heat of the engine can fuse it to the interior of the engine with a caking of hot glass, which ultimately can cause the engine to cut out completely.
University of Michigan astronomy professor Hugh Aller, who worked on the project, told Reuters news agency that the process of accelerating the material to nearly the speed of light was similar to what happened in a jet engine.
So GE brags about the terabyte of data that flows out of a single jet engine on a single cross-country flight.
However high-bypass engines are built in the future, at their core they will still have a basic jet engine.
There is another way to build a greener jet engine: by bypassing the turbine to an even greater extent, with an open rotor.
The engine allows a spaceplane to take off from a runway like any normal jet, and go as fast as Mac 5.5 on a jet-like engine.

Modern manufacturing processes combined with electronic fuel control and engine diagnostics make a single-engine jet much safer than earlier models.
As the wine passes through the funnel, air sucks into the holes making a sound like a very small jet engine.
One way to increase the efficiency of a high-bypass jet engine is to turn the fan into an open rotor, a bit like returning to propellers, but using two rings of stubby counter-rotating blades.
Cirrus is considering a single-engine jet aircraft to compete with single turboprops from New Piper and EADS Socata.
Once at 41, 000, I pulled the throttles back to 220 pounds per hour of Jet A fuel per engine.
Both BA and KLM, after all, had direct experience of what flying through volcanic ash can do to a high-bypass turbofan jet engine.
Then they realized people would have to fly without the reassuring blur of propellers turning and dropped the jet engine like a hot potato.
FORBES: Leaders Embrace Innovation. Eccentrics Indulge in Obsessions.
When aeronautical engineers started perfecting the jet engine (a process that took a few decades), they dreamed of airplanes that would move much faster and carry much heavier payloads.
FORBES: Leaders Embrace Innovation. Eccentrics Indulge in Obsessions.
In any case, the failure of one engine would be unlikely of itself to cause a crash, as a modern jet could keep flying with its second engine alone.
