We just announced licensing availability of our GYROWND Model 1836 1.6kW NP, rated at 1.2kW in 11 m/s wind flows mounted at 15m height without obstruction. the Model 1836 50lb "DIY" do it yourself package which ships in a 5ft by 18in * 18in package.
This system is a QBlade Simulated design driven to meet a target MSRP of US$2995.00, so extremely low cost, and takes a first time installer a 1/2 day to assemble the pre-assembled components and parts provided, including a simple lightning protection system.
Ideal for keeping your operation up and running during power black outs and brown outs when you have a 10 to 25kWhr battery connected to act as the prime source of power to your local use of power.
If you are a distributed crypto miner, and also need lights on, power to the fridge, freezer and stove, and the heating/cooling systems, a properly sited GYROWIND Model 1836 is up to the job for most applications consuming 2-3kW/hr during the day and less than 1kW/hr during the night, or non prime time operation (with the battery arrays mentioned above)
We have designed the GYROWIND powered generator Model 1836 to work with the OTS Missouri Wind and Solar alternator/generator and their Battery Controller systems for Wind and Solar https://mwands.com/
We have tested the basic low cost MWS generator to produce 1.6 kW at 1600 rpm for the generator, which we match with a 2:1 driven wheel to flywheel ratio. Model 1836 has a top aerodynamically regulated speed of 800 rpm in flows 21 m/s or higher.
MWS has a nice Solar+Wind Battery Controller/charger kit which matches up well to the GYROWIND 1836.
The 1836 designed life is 20 years.

The GYROWIND Model 1836 design is a low TSR "Tip Speed Ratio" design responsive to accelerations (wind gusts), delivering lots of torque across a board power curve between 2.3 and 3.3 TSR. The airfoil telemetry and blade geometry and mount position are key to creating a wake which ensure proper flow through the system from startup all the way up to 18 m/s wind flows, at which point aerodynamic self regulation of rpm kicks in to protect the generator and rotor structure at wind speeds higher than 18m/s by keeping the power output the same level at that point and well below the 2kW recommended power input of the battery charge controller.
TK tech note- Tip Speed Ratio "TSR" simply shows the speed the fastest portion of rotor blade (tip) moving versus the speed of the wind (flow) in which the rotor blade is placed. So a TSR of 2.3:1 simply means the rotor at its fastest point (in our case the working equator of the rotor blade which is moving parallel into, through and with the incoming flow as the blades rotate in a circle, our "tip") is 2.3 times faster than the incoming flow, creating the most lift in the attack phase while heading "windward" into the flow, creating some additional useful lift in the retreat phase of rotation (at a different time the attacking lift is generated), creating this lift in what many call a 'tail wind" as the rotor blade move to the backside or "leeward" position of the rotor system relative to rotor blades in the most windward position of the flow, where such rotors will be in a "dynamic stall" state generating no lift (shedding flow eddies which create turublent flow through the rotor system cavity), where the airfoil shape of the rotor blade is perpendicular to the flow during dynamic stall. Because the lift phases of each rotor blade are 72 degrees apart, and the lift of each rotor blade occurs at different times in the flow in different flow states clean, semi-turbulent and turbulent, the 1836 five blade rotor has evenly interleaved and relative flat "torque ripple" at the rated speed of 11m/s, which you can see from the diagram below as the "thick blue line" in the bottom right panel of Qblade. "Smooth" torque ripple is a designed in feature of the 1836 which helps increase the mechanical life of the strut and blade connectors and bearings, a feature wholly dependent and a result of the rotor blade geometry and telemetry we have designed into the 1836:
Rotational Torque "Ripple" @ 11,m/s showing a hefty and consistent 50+ Newton meters or 36.88+ ft lbs of torque in the bottom right panel accelerating and decelerating to 60 Nm for a +-10 Nm variation in the torque generated, more than enough torque or mechanical power to consistently overcome (create the work) and rotate the electrical magnetic resistance of the Missouri Wind and Solar PMG "Permanent Magnet Generator Set. The accelerations and deceleration of "mechanical power" between torque curve "peak and trough" maximums and minimums are easily handled by the 1836 designed mechanical connection points (Strut to Hub, Strut to Blade, Blade to Cowlings, Hub to Drive Shaft, DriveShaft to bearing assembly mounted on the fixed shaft) all of which make use of low cost readily available materials, OTS "Off The Shelf" hardware and "low cost labour" fastening methods to keep the price of 1836 affordable.
The MWS controller/charger for wind and solar provides an electric brake system in their controller/charger package for Wind and Solar, and the recommended way to slow down and stop the rotor, before tilting and then tethering in stationary position to wash or repair nicks in blades, lubricate bearings, inspect or change out generators or the driven wheel if needed. We expect both the generator and driven wheel to last 20 years under normal operation, where there is little sand or grit in the wind flow.
