Wind Amplified Rotor Platform (WARP)
The WARP wind amplifier module design, by ENECO Texas, LLC, speeds up the wind with a velocity amplification factor (VAF) in excess of 1.5 over free wind. This amplification factor means that an increase of 65% in wind speed would result in a 4.5-fold increase in power due to the fact that power increases as a cubed function of wind speed increase. 1.65 x 1.65 x 1.65 = 4.49
The aerodynamically-designed, repeating hourglass shape essentially focuses the wind energy onto smaller turbines. This makes wind generation more modular and hence more affordable, increasing ease of maintenance, and decreasing downtime. A WARP wind farm would need on average about 80% less land per kilowatt of energy generated. Visually, the WARP design is more appealing and blends into building designs better than the traditional horizontal axis, large, three-blade turbines.
Projected cost: $.02 to $.04/kW-h or lower.
Prototypes have been built and installed in Belgium and France.
The company business model is to license out the concept for others to implement in desired territories (can include countries, states/provinces, etc.) and in desired application markets (wind farms -either onshore &/or offshore, architectural buildings, telecom towers, electric utility transmission towers, etc.).
The design can also be applied to water flow.

- Download (13 Mb; mp3) - On Sept. 22, 2008, Sterling D. Allan conducted a live, 1-hour interview with Alfred and Gunther Weisbrich, founder and inventor, and business partner, respectively, as part of the Free Energy Now radio series.
How it Works
"The aerodynamically designed toroidal-shaped amplifier modules are vertically integrated on a core tower, in building block fashion, allowing the system to be packaged to any power size from utility to commercial or village power scale. For large capacity systems, each module has two rotors, typically 2-3 metres in diameter. WARP's panelized design also lends itself to the piggybacking of photovoltaic cells on its structure, thus making it possible to add 10% more power through the use of WARP as a combined wind/PV power system.
The WARP™ design is comprised of a stacked array of wind amplifier modules that can employ relatively small (typically 6 ft or 10 ft) diameter rotors. The design has each rotor direct drive a generator, thereby eliminating the need for step-up gearboxes. These same modules are capable of amplifying the ambient wind speed by up to 1.8 times free stream values (e.g., 10 mph ambient speed become 18 mph wind speed at the rotor disks).
The process (which is based on the Bernoulli Principal) is similar to nature's highly sought saddle ridges for wind turbines. The only difference with the WARP™ design is that the wind can be accepted and channeled from any direction.
The multiplicity of two opposite turbines at any WARP™ rotor level (~180 degrees apart about the tower) may continuously and passively orient themselves perpendicular to the ever changing wind direction. The modules are attached to a core (e.g. lattice or tube tower) support structure that can also be built to virtually any existing tower height.
This unique design can also be integrated to many different kinds of structures-e.g., telecom towers, buildings, offshore platforms, as well as utility scale transmission towers."
Projected COE is in the $.02 to $.04/kWh range.
- WARP's higher energy capture capability, and small unit spacing because of shortened perturbation from its smaller rotors, a WARP wind farm would need on average over 80% less land per kilowatt of energy generated and also be able to use much taller structures than possible with conventional systems. Some other features mentioned by Mr. Weisbrich were WARP'S lower noise, no electromagnetic interference, absence of gear boxes enhancing reliability and the avoidance of pollution from hydraulic and transmission fluid leakage, substantial fuel savings when integrated with fossil fuel plants in a stand-alone system, and less danger to birds.

A $1.5 million expenditure on research and development through Rensselaer Polytechnic Institute (RPI), under New York State Energy Research (NYSERDA) support, as well as with prospective licensees testing WARP for various fields of use, has resulted in a convincing data base for the WARP technology. In addition, independently sponsored research has been conducted overseas, including computational fluid dynamic (CFD) analyses at the Technical University, Graz, Austria, and, recently, wind tunnel tests in Denmark. The results corroborated those generated by Rensselaer's scale model wind tunnel tests. With reference to the Graz CFD tests, it was also noted that tallstacked arrays of WARP modules would produce a VAF of 1.7 to 1.8 on average of the free stream wind speed, resulting in a relative maximum power of approximately 5 times that of the free air turbine.
A pre-prototype test of a WARP unit yielded significant data but unfortunately the results were limited because of a force majeure 100 year storm. On the positive side, although the storm destroyed all the costly and complex customized test instrumentation, including the on-board computer data acquisition equipment, it did not significantly damage WARP's modules and turbines. Depending upon site wind and module height, each WARP rotor is capable of, generating lOkW to 50kW by small, conventional high efficiency horizontal axis wind turbines at rated wind speed. WARP's modular system makes it is possible to tailor its power capacity from kilowatt levels to multi-megawatt levels without the need for costly rotor redesign and retooling. Plus, with the coincidence of optimum rotor rpm matching generator speed, the need for gearboxes in the WARP system is also eliminated.
- Wind amplified rotor platform (warp) Patent number: 5520505
- Abstract: An energy conversion device which comprises a stacked array of alternating yawable and fixed toroidal modules about a central core structure. The yawable toroids have typically four impact impellers mounted in their peripheral flow regions for the purpose of capturing flow energy. The fixed toroids are mounted to complement and further enhance fluid flow impact impeller energy capture and to provide housing means for a variety of matter both associated and unassociated with the energy system. The stacked array of a toroid with impellers, designated a Toroidal Rotor Amplifier Platform (TRAP.TM.), and a toroid without impellers, designated a Toroidal Wind Frame (TWF.TM.), is referred to in aggregate, when used for wind energy conversion, as a Wind Amplified Rotor Platforms (WARP.TM.) system. Under wind energy conversion use, a WARP.TM. system may be used also to both generate electric power and serve as a power line transmission support tower, and/or as a telecommunications or...

- Circumvention Attempt
- "We are very familiar with this design. It actually is a result of this group attempting to circumvent our WARP Patent. We had been 'engaged' by them for a long period of time -- but when they could not pay for the WARP license rights they thought it easier to 'screw' the design -- which has obvious aerodynamic and performance flaws associated with it."
