I've seldom hear them bark so. When they are moving about slowly they are as dangerous a hybrid car. Almost completely silent.

About half the engines I filmed in the video above are Baker Uniflow engines. Those have a different sound if you listen carefully.

Sawmill, Baker fan (the yellow fan), and an assortment of power eaters as loads so they can show the engines doing serious work.

The power eaters are ridiculous because they dump the electric load to essentially big power resistors (heaters!)

So on a day when it's 90F they are lighting a fire, taking the heat energy to make steam, using the steam to convert the energy into reciprocating motion, then to electrical, then back to thermal energy they dump into the air. :lol:

And with my launch I'm burning wood (originally solar energy) and perhaps a few percent of the energy goes to moving the boat along and making a few pitiful waves.

So much more worth it. You are, going places! You are slightly warping the fabric of spacetime.
