2 1/2 HP Demo Hydrogen Engine
This little project took shape
in November of 2002 when I came across a neglected lawnmower in a flea
market. I bought it for $25 and proceeded to work on converting it to
hydrogen. It is similar to an example built by my mentor, Roy McAlister. I
wanted mine mounted in a wagon so I could easily transport it for
lectures. List of materials includes:
1- Wagon - $39
1- Swagelok SS valve - $49
1- Hydrogen tank and Regulator - $300 (1800psi)
1- 13" X 31" sheet of 1/8" aluminum - $18
3' of 1/8" copper line - $3
Vastly over budget of course, but I wanted new stuff the first time out. I rationalize the cost as the 'entrance fee' for my "education". Today I could probably scrounge stuff on E-Bay for 1/3 the cost. The engine was rebuilt and the pull starter replaced. I have already made good use of the wagon in hydrogen lectures.
Anyway it was a fun learning experience and nothing can replace the satisfaction of firing it up for the first time!
Future plans: add on an AC generator.
