The HEMMKILL-Maschine - A Valve Stirred Version of The STIRLING-Motor for The Utilisation of Moderate Temperature Differences as Given By Geothermal and Solar Energy. — •Hermann. M. M. KILLESREITER — Private Creations D-38678 CLAUSTHAL-ZELLERFELD

As an example for popular science terms will be regarded the PER- PETUUM MOBILE in an artificially constructed world, which finds in practice many machines using well-known so-called unlimited energy reservoirs[R. BECKER: Theory of Heat].

Following this line and remembering the CARNOT-Process, there will be given an introduction into technically important phase diagrams of ACKERETT, KELLER, JOULE, LORENZ, STERLING and PHILIPS and be explained the thermodynamics of the HEMMKILL-Machine, the name of which arises from the author’s initials. Most importent is always the efficien- cy of machines, which has been derived as

Eta = 1/[(Cv/R) ln(T1/To/lnV2/V1)+1].

Finally, there will be outlined some technically possible applications using geothermal and solar ener- gy, last not least referring to the ocean as one of the infinite energy reservoirs. hmmk
