Utah-Based Company Digging Underground Compressed Air Batteries

Utah-Based Company Digging Underground Compressed Air Batteries

Underground caverns may have never been seen as energy containers, but a Utah-based private equity group promises to use them filled with compressed air to generate electricity the classic way – by spinning a turbine.

Air Powered Motors: Small as Watermelons, More Efficient than Diesel

Air Powered Motors: Small as Watermelons, More Efficient than Diesel

If you watch The Green Optimistic you already know that we covered air cars in previous posts, both MDI CAT’s and the Angelo DiPietro air motor. The first time we wrote about these inventions was about 6 months ago. Now, MDI and Angelo DiPietro have contracts all over the world with auto makers to sell them the compressed air technology so automakers do what they do best: cars.

Air Powered Motoscooter

Air Powered Motoscooter

The TV presenter Jem Stansfield modified this small moped to function on compressed air stored in two high pressure carbon fiber tanks, like the ones that the firefighters use. The engine has been replaced by two rotary air engines.

OneCAT – the car that runs on air!

OneCAT - the car that runs on air!

Remember an older article about a small company, called MDI, who had a plan in building a car that runs totally on air? Now they did it. OneCAT is a five-seat car, with a fiberglass body, weighting about 350kg and costing about… 4800$! And that’s cheaper than any car (maybe except the recent car from [...]

How To Build a Tesla Turbine From a Hard Disk Drive

How To Build a Tesla Turbine From a Hard Disk Drive

Disks
At first I tried using CDs because of their large surface areas, but they didn’t hold up too well under the milling machine. I also had a stack of platters from old and defective hard drives, but I didn’t know if the smaller diameter disks would work as well.
One problem I ran into is that [...]

How a Slotted Disk Turbine Engine Works

Introduction.
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 help [...]

The Quasiturbine Pneumatic Engine

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
of 200cc per revolution each, [...]

The Tesla Turbine

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 [...]

The Rotary Air Engine (Di Pietro motor)

The Di Pietro motor concept is based on a rotary piston. Different from existing rotary engines, the Di Pietro motor uses a simple cylindrical rotary piston (shaft driver) which rolls, without any friction, inside the cylindrical stator. The space between stator and rotor is divided in 6 expansion chambers by pivoting dividers. These dividers follow [...]

E.Volution – the air powered car

Within the next two years, you could see the first air-powered vehicle motoring through your town. Most likely, it will be the e.Volution car that is being built by Zero Pollution Motors, in Brignoles, France. The cars have generated a lot of interest in recent years, and the Mexican government has already signed a deal [...]
