This must be the most inefficient thing I ever saw. Probably not even those earliest atmospheric steam engines were worse, least you should make some use of the spent steam rather than waste it. As far as I can see this is a JOKE....!!!!
Below 50 hp tesla and other vaned high speed turbines suffer from terrible inefficiency due to leakage. Steam is 1000 times smaller than air molecules. So the quest is a rotary that is efficient below 50 hp. Sealing is the issue and I have that solved.
I like no more than 100 psi for several reasons. but with the right materials you could go higher. Rpms are about 500-750 without going over 100 psi. This little engine ids designed for high speed and electric generation. I am hoping to make a larger 1000 watt version. Too many things to do. Now I know how Leonardo felt.
would a water cooling jacket around the engine feeding back to your water tank ( cold ) help the efficiancy and time between water recharges ( a kinda pre-heat )
No, actually it would be better to insulate the engine and retain the heat. There is plenty of heat in the exhaust to heat water, the house, etc... You want the steam to expand, not condense.
When this engine was first made we used a poppet valve actuated by the flywheel. So the flywheel has varying thickness. It worked ok but there was a lot of friction. So the wobble is just a relic of the first experimenting.
I haven't drawn up plans for this yet. It hasn't been quite right to call it done. For one, I'd like to simplify it. Secondly, it doesn't really gasify as it is built now. I have to design a way for the gases to heat pyrolytically, and pull up the sides and burn after mixing with oxygen. I will work on this over the christmas break and get out to you.
I have been so busy, I haven't followed up on everything I need to do. The boiler as I made it is still too complicated. I need to show everyone the easy way and I just haven't focused on detailing.
Bricks, sheet metal and a single size copper tube, a few fittings.
I have simplified the controls to stupid simple. be patient and I will get this posted.
The displacement of the Typhoon Rotary is 24 cid. This is equivalent to a 3" bore by 3.5" stroke double acting steam engine. The parts count on the Typhoon is small with just four moving parts and case. If steam admission can be accomplished centrally in the shaft it will be very simple. Also the heavy case and base are unnecessary.
The valve noise is actually the flap (virtual cylinder head) being struck closed and bouncing in its seat when the engine is running faster than the velocity of the steam. Notice as the engine speed it quiets. This can be solved by adding a load, or automatic timing. Parts don't show any wear after 30 hours.
Yes, far more powerful. Turbines when they are this small suffer from immense leakage and rely on steam velocity. This engine is under force/torque for 75% of the revolution with no back pressure. This engine does leak a little, but much can be solved.
Look up axial flux alternators. These like low rpms and don't cog like most alternators.
You will hear valve noise at certain rpms in the video. Like most engines this engine would benefit by varying the timing and cutoff. That's next.
Thank you for sharing! I've been wanting to do something like this for a long time. Do you think with the valveing involved that your motor is more powerful than just a turbine the same size, torque vs. rpm with less moving parts. If you can please make me understand. I would think that you want to get close to the best genset rpm you can, to avoid a gear box other wise I don't really know. Keep up the good work.
Is it me or is your flywheel grossly distorted?

how about a recycling exhaust system that muffles the sound condenses the steam and pumps it back to the tank .

Hi, I think an H2O molecule is a tad bigger than any of the air molecules.

Have you evaluated turbines like the Tesla, are they more efficient in this small scale ?

What is the PSI for operation and what is the RPM's with out over heating.

@LynxSteam
i understand :)
i asked an old steam engineer in the pub last night the same question and that was his answer too .
I stand corrected sir :)

@LynxSteam
so would it be possible then to have some kinda combined cycle set up , steam/hot water and the lynx rotary powering a battery charging alternator .

is the fly wheel wobbleing or is that the camera? if it is, why is it wobbleing?

I'm really interested in getting plans for gassifier boiler. Do you offer plans for sale?
