Hello! It have been long period that I haven’t send anything, so now its time to show some proov that it is possible to run gasoline engines on hydrogen. I did not modificate this lawnmower, I only removed filter which was on carburator and just put tube whit hydrogen in. Here you see I create hydrogen by using easy method: Water+NaOH+Aluminium = Some gasses + Hydrogen I was glad to see my lawnmower did run even 20 seconds whitout gasoline, just hydrogen and air. So now I even know that I can power lawnmowers whit hydrogen. So I continue to make cells more efficency. In this video you see small time running maybe 2-4 seconds at most. But still there was no gasoline in tank. Please! Rate, Subscribe and Comment Thank You All!
