"We have proven the validity of our concept by making a simple small scale working model which is now supplying all the heat, light and power needed for our four story 52 room University. Our reactor generates much more power than needed for whatever purpose intended, so enough of that surplus is taken off from its generator to motivate the reactor in perpetuity.
Nuclear reactors need whole buildings for operation while ours occupies no more space than a furnace or oil heating plant to house its reactor, its steam-turbine and its generator. The nuclear reactor must be prevented from harming humans by building great concrete walls around it, while ours is perfectly harmless and occupies so little space that the one which operates at our headquarters occupies hardly more than six cubic feet, has no moving parts, and weighs not more than four hundred pounds, exclusive of its small steam turbine and generator.
It is needless to say that such a simple, mobile, light and power producing machine would not only effect the whole world-economy, but would be the first step in bringing abundance of the necessities for human existence to every nation on the face of this earth." - Walter and Lao Russell
