This "steam" engine runs (backwards) on vacuum cleaner power. The motor generates approximately 700RPM. The design is based on Daniel B. Hartman's Lego steam engines.

  • i built this a few years ago and still have it

    its an awesome piece of machinery

  • how does this work and could you send me some plans or a link to a good website for plans?

  • Oh, never mind. I found out how it works and already have a video about it in my channel.

    "Lego vacuum engine". Works pretty good

  • i made a Lego steam engine with a 2 by 2 cylinder. there's a video similar to it somewhere. it has a separated valve cam too!

  • Now my engine works too, I also uploaded a video about it. Yeah, there are other ways. You can also use compressed air,for a cylinger. I built one yesterday...HOLY, it works really good.

  • ive made it to and it doesnt work. To much friction but it started to work. Also is there another way to make this without using the vacuum cleaner?

  • WHY? WHY does it work on yours and not on mine?? BUHUUUU ;`-((((

  • not bad...about 2-3 hundred RPM lol

  • Ok I have watched your, and other's engines like this. And built my own from what I could see. I pulled up everything there was on it. But mine wont work. How did your work, and do you have instructions?
