<br>
Interesting that he now states the efficiency:<br>
<br>
"<font face="Trebuchet MS, Arial, Helvetica"> When the steam is
simply exhausted to atmosphere while
running a generator, for example, efficiency is relatively low;
in the area of
15%. When the exhaust is condensed and recycled back to the
boiler, the
efficiency is around 24% to 30%. When the exhaust is condensed
through a heat exchanger
whereby the condensation process is used fully by heating water,
space and
distilling water, for example, the efficiency can be in the 70%
range."<br>

Penn State University didn't seem too carried away:<br>

Looks like he ran this one on steam:<br>

The old saying is that every gallon of water in a boiler equals a
stick of dynamite!<br>
<br>
I can buy a Honda clone engine, on sale, for $100 and skip the
dynamite. Just need to add the gas producer.<br>

There is a lot of internet forum chatter dissing this guy.
There are no working versions actually working on steam
anywhere in the world as far as I'm aware. Even his own videos
show the units operating on compressed air, not steam. Also he
only sells plans and a few of the hard to source parts for the
engine itself, not entire units premade.</span></div>
