"The whole is greater than the sum of the
parts"
The secret to the success of these micro turbines is in Albert Einstein's law were he quotes "The whole is
greater than the sum of the parts". This is perfectly demonstrated here. When you try to move one turbine so as to turn all the others (because they are cogged together), it is hard to do. But if you move two turbines it only takes half the amount of force. So if you have ten turbines set together you only need to apply a small amount of wind to each turbine to make them all move.
In general most wind is from two directions. If you have a NW wind you
will likely have a SE as well. This works well for the base model as the turbine blades are designed to accept wind from 0 to a 35 degree angle. So from NNW to NNE and from SSW to SSE if your turbines was facing North or South.
10 turbine unit
This is your basic setup. Great for an apartment on remote cabin.
Simply add another set or two and you will have enough to run a home.
10 nylon micro turbines with generator rated 60W for 10m/s wind.daily
production : 1.2 kWh .output 12 to 48 volts
Best application between 1ms and 10ms wind speeds.
Frame 1.02 meter long x 0.54 m height x 0.14 m wide. Stainless steel
main support with 2 stainless steel post (0.82 m long)
6 turbine
unit
As you can see this unit can be used in areas were wind direction is
not coming from a constant direction.
6 micro turbines with generator rated 50W for 10 m/s wind.
Output 12 to 48VDC volts non-regulated.
1.6 meters span. Works from 2 m/s wind speed.
This has been designed for camping
The turbines can be set in any number of shapes, from a straight linewhich is the most efficient to even an "L" shape. They are easy to install and require minimal tools.
Each turbine is only 250mm across and are made heavy duty nylon. They
sit on fine sealed ball bearings and stainless steel mounts.No grease is needed and they produce very little notice. We have had them running in sustained 100 km/h winds and they just love it.
11 turbine unit with suction pump
Pumping water is a way to store energy for a hydro system as well as field irrigation or for the home and lifestyle block well. I you live"Off Grid" then this is a must.
From 2 to 3 ms with gusty winds.
Suction capacity :approx 50 liters/hour from 8 to 9 meter depth or
25liters/hour from 20meters depth
Suction + pressure capacity: approx 100 liters/hour from 8 meters depth
to 10 meters high
This pump is design to work over very long period of time .unlike electric pump there is no internal heating and there is no need to let the system rest.once the pump is taking wind it will keep working.
11 turbines in line with a central connected worm gear box(1/20 ratio)in aluminum casing and oil tank connected to a 0.2 liter piston pump. body made in brass,piston in nylon,all other parts in stainless steel,supplied with different O rings sizes to control the wanted internal pressure.2 brass plated valves.1 gravity valve for the suction part and a pressure valve for the pressured exit.this pump generates
approx 5 bars for high wind speed(50m high)and has a maximum pressure of approx 10 bars.there is 3 different setting for the pump course depending on volume or pressure wanted.pumps using wind energy have not so many regulations system possible so the final setting will depends on experiment by the user.this pump is ideal for many long lasting work,watering gardens/fields,filling up swimming pools/ponds,bringing
up water from wells and pits,and many more applications to come.you can store the unused energy collected by filling up a reservoir on high altitude .Motorwind Pumps work also in stage level,that means that by
having more than one pump at different altitude you can bring up water to basically any height.for example if you have enough wind energy to pump water to 30 meters high then by using 5 pumps in stage,you can
pump water up to 150 meters.
Deep well pumping: a suction pump can lift water from a depth of 10 meters maximum.this is due to the laws of physics when pressure = gravity .for deep water pumping we have an other additional set to be
added on this pump.it works by combining suction and high pressure. water can be pumped up from 40 to 50 meters using just 2 regular hoses.
Efficiency: an electric pump has an efficiency of approx 20%.that means that it takes 1 kWh of electricity to deliver approx 0.2 kWh of work done(720kJ).it takes approx the equivalent of 3 kWh in energetic value
of oil or gas or coal used to produce this kWh,so we can say that the efficiency of an electric network to deliver a 0.2 kWh worth of work done is only : approx 7%.(93 % of the energy used as been wasted).Motorwind pump has an unbelievable efficiency of between 35% and nearly 50%(preliminary test shows)and does not release a mg of CO2.
Frame 2.60 meter long x 0.26 m height x 0.14 m wide .stainless steel

Volume : 0.35 CBM Measurement : 114 cm x 26 cm x 20 cm .Weight :17 Kgs
8 units set up inline
To set up for any wind turbine system you will need; turbines connected to a battery bank and then to an inverter which is connected to your home. It really depends on your electrical consumption and wind speed in figuring out how many turbines you need.
If a large system is set up you can sell the excess electricity back to
your electrical provider. They call it exporting and basically the
wheel on your electrical meter spins backwards. There is some set up
cost. But the benifits are you great.
