The Art of Big Style Pollution: 4,500-Horsepower Smoky Diesel "Freightliner" Truck Does 228 MPH

Ovidiu Sandru — Tue, 15 Nov 2011 16:17:19 +0000

Some people may have gotten used to reading nice green inventions on our cleantech blog. This time, though, I’ll show anyone interested in pollution what some idle minds can invent in this direction. Meet the world’s first Freightliner powered by a 16-cylinder, 28.8 L diesel engine capable of no less than 4,500 horsepower! Jeremy Clarkson […]

Joseph Papp's Inert (noble) Gas Engine

Ovidiu Sandru — Sat, 15 Mar 2008 17:46:46 +0000

Like it’s said that sculptures aren’t created but discovered, because they were always there in the rock, so Josef Papp, a Hungarian emigrant to Canada discovered an engine based on the properties of the inert gases, such as Helium. It is known nowadays that these gases, compressed and ignited under certain electrical conditions, can offer […]

Preview of a Mendocino Motor (solar power/magnetic levitation)

Ovidiu Sandru — Tue, 04 Mar 2008 15:10:44 +0000

We will present a tutorial for making this kind of motor in the near future. I think it’s a great idea combining the solar power with the inertia given by the motor’s movement around its axis, floating in the magnetic field.

I got a comment yesterday from one of the “guys” who helped Josef Papp succeeding with his inert gas engine. It’s Bob Rohner, who also has a website: rohnermachine.com. He said: “To set the record straight, I built all the engines seen in any videos, not Sabori. Your article is a fine introduction to the […]

Gasoline And Steam Engine Reloaded

Ovidiu Sandru — Sun, 10 Feb 2008 20:15:35 +0000

Bruce Crower‘s engine is an innovation derived from a standard 4-stroke engine. It uses 6 strokes – the 4 normal ones, and at the end of the 4th it introduces the 5th and the 6th: – it squirts water on the 1500 °F hot cylinder, creating a steam volume 1600 times greater than the volume […]

How to Build Chas Campbell’s Gravitational Engine

Ovidiu Sandru — Sun, 10 Feb 2008 13:52:47 +0000

There is a lot of talk about Chas Campbell’s gravitational field invention, but for the beginning I will start with a few notions: Chas has invented a mechanical device which takes the gravitational energy of Earth and transforms it into kinetic energy. Principally, it uses a wheel having balls in it. It’s known that if […]

Quasiturbine Engine Works With Air

Ovidiu Sandru — Wed, 06 Feb 2008 07:40:53 +0000

Since the Quasiturbine is a pure expansion engine (which the Wankel is not, neither most of other rotary engines), it is well suitable as compressed fluid engine – Air engine or air motor. From the basic 200cc per revolution engine bloc, a compressed air prototype has been built making use of 2 parallel expansion circuits […]

Engineair's Ultra-Efficient Compressed Air Motor

Ovidiu Sandru — Wed, 06 Feb 2008 07:34:45 +0000

Elegant minimalist design eliminates most of the working parts traditionally associated with internal combustion engine; offers nearly 100% energy efficiency for a variety of transport and stationary applications. by Mary-Sue Haliburton Pure Energy Systems News Copyright © 2006 Imagine a vehicle with nothing under the hood (or bonnet), no gearbox, no transmission, no carburetor or […]

The Tesla Turbine

Ovidiu Sandru — Wed, 06 Feb 2008 07:33:23 +0000

Nikola Tesla created an engine design nearly 100 years ago that is as much as three or four times more efficient than the combustion engine design that has dominated for reasons other than science.At the time of his invention around 1909, Tesla was able to demonstrate a fuel efficiency of 60% with his bladeless turbine […]

This is maybe a lawn mower’s engine, but I think it would work for any engine. What do you think?

BMW's Gasoline and Steam Hybrid Vision

Ovidiu Sandru — Tue, 29 Jan 2008 20:51:08 +0000

Certain parts of a car’s engine can reach temperatures in excess of 1,500°F. With this in mind, the engineers at BMW developed a way to boost efficiency: Transform that otherwise wasted heat into energy the engine can use. The resulting Turbo- steamer reclaims more than 80 percent of the heat lost from the engine’s exhaust […]
