www.greenpowerscience.com This is the trough mirror and a Fresnel Lens set. The water was shot in with a hose to produce flash steam. Ball bearing were used as ammo. A few modifications from this learning experience and we can launch 200 yards.

Dan you Devil!!
you little devil!
you did not try to hook this up to a steam engine because you discovered that once water goes through your rube goldberg device it soon cooled down and no longer produced continuous steam for the engine.
you in the yard playing with water when you could be doing something far more exciting.
I was glad to see Denise show up at the end and deliver her message or reason, and safety.
Dan, after 30 years in the trenches, I reccomend you try this…
I’m sorry, you were right, I was wrong, it’ll never happen again…

Hah. You could make a gun out of a tea pot. Excellent way to end the video.
Good Job! Now Yer Talkin’ !! It doesn’t get fun until you put some danger in it !!
Just wondering if you have a flow check valve on the water line just before it goes into the pipe. Maybe you can get more kick. If that steam preasure is greater than the water preasure in your hose it may be loosing some preasure back into the hose and lessening the initial kick.
Try extending the barrel about 3 ft. & only push shot in 3 ft. creating a larger expansion chamber before contacting the shot.
Haha this guy is funny. He’s like smart and dumb all at the same time.
