Keely
In considering the operation of my engine, the visitor, in order to have even an approximate conception of its modus operandi, must discard all thought of engines that are operated upon the principle of pressure and exhaustion, by the expansion of steam or other analogous gas which impinges upon an abutment, such as the piston of a steam-engine. My engine has neither piston nor eccentrics, nor is there one grain of pressure exerted in the engine, whatever may be the size or capacity of it. [Keely, see Keelys Accomplishments]
Russell
"A vast mass of the vacuum cold freezes our sun into its density and keeps it from exploding. Some suns generate heat beyond their melting points and explode as novas, but some of them are conquered by cold before they expand beyond the limits of their exhaustion." [Atomic Suicide, page 159]
