Now, a large team of UK engineers and scientists managed to develop a real and working […]

What is an ICE, in its simplest terms, but a air pump? Compressed-air motor [CAM] vehicles, though, are light, slow, and not very practical for the average user. Liquid Nitrogen [LN2] could be […]

Dean Benstead made one for himself and shows the concept to the world. Compressed air has been one of the fields “in vogue” a few years ago (namely, four or five), ever since the invention of the DiPietro […]

The engine has been replaced by two rotary air engines. The two tanks can be fully charged in a matter of seconds from any air compressor. […]

The purpose of this paper is to offer the reader some insight into how a bladeless steam turbine can be constructed and used. The use of inexpensive slotted disc turbines in place of much more expensive bladed turbines can fill a void in the need to convert heat energy to electrical energy, and can […]
