CO2 powered mechanical device
« on: November 23, 2016, 07:30:48 AM »
CO2 remains liquid to -47C then changes to gas at +31*C. CO2 at -47C has 10 bar pressure rising to 10,000 bar pressure at +80C. Steam at +600*C has 200 bar pressure, while CO2 has 200 Bar pressure at +50*C.  CO2 is now a common Refrigerant and achieves its cooling by an expansion chamber. This heat to force activity is ideal for mechanical purposes such as driving a turbine generating electricity.

Hello Aussi( ;) ), I like the ideas to use ex-garbage -now worthfull recycleable resources- as energy carrier,but here  -your idea related- now my question : 10000 bar  :o how will this engine become evacuated/sealed ?

High "technical/physical" ::) pressure has been my "mental" barrier to work out a real prototype of the Wilhelm Haeberle CO2-Medium-engine
Heat energy is converted at low temp. into usable mechanical energy. With the use of CO2 as the working medium, a reversal of the usual behaviour of the working medium sets in at the negative inversion region. The method is represented in the t-s Mollier diagram for CO2 and the sequence ABCD comprises two adiabates AB/CD and two isochores BC/DA. USE/ADVANTAGE - Engine which makes use of the principle of unlimited 'environmental heat' for the prodn. of mechanical energy.
Such heat pumps are because they have few moving parts, very simple in construction and hence inexpensive to manufacture. Crankcase with drive motor in hermetic - autoclave, vorgefullt/prefilled with air at about 10 to 50 bar results in large air mass and small machine by oil mist - circulation lubrication is achieved a lifelong maintenance-free.
Mosaic Figure 2 : up to 2800 at(u) for this small engine
1 at:= 10 mWS = 1 kp/cm² = 9,80665 N/cm² = 0,980665 bar = 98.066,5 Pa

seal concept: pressure at beginning 300 bar and end pressure 3000 bar

Hello lancaIV,

The unit is little more than an Absorption Fridge workings using a turbine as its choke point and a screw for Fridgerant return. Sealing the shaft is by rings -attached shaft- and housing - with no contact on rub point. Metal for 10,000 bar pressure needs be Stainless Steel. Lower pressure model is 10 Bar, 1 Litre per second, 1 Kw.
