Windspire is a complete consumer-friendly appliance that is designed for plug-
and-produce installation. All of the components were designed for integration
together to provide seamless, reliable operation and easy installation.
The rotor is a low speed giromill (straight-bladed Darrieus) design optimized for
energy capture efficiency by Ecole Polytechique Montreal. The Darrieus rotor
was researched and developed extensively by Sandia National Laboratories in
the 1980's. Our rotor has modified this proven, high efficiency configuration into
a size and form optimal for personal power generation. The changes also
lowered the operating speed, making it nearly silent, while also improving self-
starting capabilities. Constructed from aircraft grade aluminum, the rotor is both
high strength and low cost.
The Windspire has its own integrated inverter to convert the raw electrical power
from the generator into regulated electricity that ties in with the grid. The high-
efficiency inverter was custom designed by the best electronics designers in the
industry, to optimize operation with the rotor and generator. The inverter
technology continuously maximizes the conversion of wind energy into electric
power provided to your home or business, over the range of wind speeds.
Double Rotating Air Core motors and generators are seen as the future. They
provide the highest efficiencies ever achieved, with some operating at over 99.0
percent. New manufacturing
technology allows them to be produced with both the highest possible efficiency
and simultaneously at low cost. The Double Rotating Air Core generator used in
Windspire is designed specifically for the rotor to efficiently capture as much
energy as possible at all wind speeds. The Windspire generator technology
was dynamometer tested and its performance verified by Oregon State
University and the University of Nevada, Reno, under a program sponsored by
the National Renewable Energy Laboratory (NREL). It acheived over 98%
Sometimes it can be nice to know how much energy you’re producing each
month, let alone how much you made from that big windstorm last week. A click
of your computer can provide you all of that. The Windspire has a built-in
wireless modem that’s always transmitting power production information. With
the zigbee dongle (much like a flash drive) plugged into your computer's USB
drive, you can monitor the performance of your Windspire. It doesn’t get any
What It Means to You
Through creative innovation with advanced engineering Mariah Power has
developed the optimal and most cost-
effective wind power appliance for residential and commercial needs.
Windspire is a truly revolutionary wind energy solution.
Why Windspire is So Revolutionary
You may wonder why you haven't seen a product like Windspire on the market
before, or why it's taken so long to see a viable Vertical Axis Wind Turbine
(VAWT). Unfortunately, VAWTs have had a rocky history in the market, mainly
due to low efficiencies. It is an engineering challenge to harness sufficient
power from low rates of rotation in a cost-effective manner.
We began by developing an extremely efficient generator that is optimized for
those low rates of rotation, and followed this with breakthroughs in rotor design
and construction. In the end, we developed a solution that finally overcomes the
hurdles of cost and efficiency, with our truly revolutionary Windspire wind power
appliance. Finally, to really set Mariah Power apart from the rest, we verified our
results with rigorous independent, third party testing. With multiple international
patents protecting our innovations, Mariah Power is poised to change
renewable wind power forever. Join in the revolution!
