Well unless you want to use sea water, the steam system is a net loss
requring some continious amount of "makeup" water. The vessel will be
required to carry both fuel and water. Or, as I said, boil sea water I
suppose.

they say it will use any water , and stainless boiler,
designed to be not fussy, time will tell
also any heat source can be used, solar collectors maybe for small boat
engine.
looks elegant and fun

if this really works as promised it should be the propulsion of choice for
many crafts. simple, light and elegant.
but I still wonder if it really works?

price will be the main issue I guess. While the website says it is cheap to
build nobody mentions it will be cheap to buy. They have a patent on this
which may make this engine really expensive - at least the first couple of
years until it becomes mainstream.

Time will show..

Injecting steam at "supersonic speeds" is going to require a really high
pressure boiler. Hot seawater is extremely corrosive and as the water
boils off and the salt concentrates it will get even more so.

Even in fresh water just think of the crud that will build up in the
boiler. Seems like a neat idea though.
