So sorry to bring rain to the parade..
Reality is like that. The internal combustion engine is noisy, stinks,
pollutes, and it's inefficient. However, to date, there is no practical
replacement for use in motorcars.
I'm not looking to use it in a motorcar ...
You might find these interesting. Jim Ettaro did many experiments
with small gas turbines using hydrogen as a fuel. I saw his
turbocharger air pump run and I also saw the one in the second
article run, and he had a third version he built that I saw run.
Each was quite interesting, and the startup procedure did not appear
that complex. It would have been fairly simple to automate start up
and shutdown with Jim's designs, however making one of the designs
"failsafe" may not be simple.
Video of his small hydrogen turbine used to be on the calstate LA
website, but I have not been able to find them for many years now. I
wish I had downloaded and saved them. However Virgil Seaman at Cal
State LA may be able to provide the video.
Shhesh! Okiebanz has lasted longer than Mercedes veterans or the
I would theorize that the small size of Jim's turbines and the
hydrogen fuels avoided some of the problems Grant and Dan encountered
with larger versions. What is called a Microturbine generator (like
a capstone) is in the 30 kW range, so is substantially larger than
what Jim was dealing with.
I don't remember what engine he got the turbocharger from, but it was
similar in size to the one on the 1.6L VW turbodiesel. The final
turbine engine I saw (that Jim made) was about 5" dia also.
