About this project
The world needs more clean energy but for many people, the cost is too high. Building on the successes of conventional wind power technology, Pacific Sky Power has developed affordable wind turbines that can be used at many different locations. If you don't have a good spot for installation, we also have towers. These systems are good starter kits for learning about this technology.
Wind turbines convert kinetic energy from the wind into mechanical energy which spins a generator to produce clean electricity. Our wind turbine is rated at 15 watts which can be used for charging 12 volt batteries. They’re great for camping, on boats and science projects. The 30 and 45 watt wind turbine systems include multiple turbines on a specialized tower.

Risks and challenges
To develop these products we have conducted extensive tests to measure output and durability of components. We started with a 14” long propeller and recently switched to a 15” long propeller that is stronger and performs better in all wind conditions. With this improvement, we saw a 50% increase in power production. Our tower kits have also been upgraded with a stiffer tower and other structural features for improved performance.
Like most manufacturing projects, we will face challenges with expanding production but since we have already started low rate production feel confident in taking the next steps. After a successful Kickstarter campaign our team will order materials and components, manufacture each system with attention to detail, test to ensure the generating capacity is good and ship all rewards to our backers by the end of June 2013.Learn about accountability on Kickstarter
Yes, you can connect the power cable of the wind turbines directly to a 12 volt deep cycle battery. You do not need a charge controller but we do recommend using one while using multiple turbines. A charge controller will help to optimize the power production. We have had success with the (Flexcharge Controller NC25A-12).
No, our wind turbines are equipped with a blocking diode. The blocking diode acts as a one-way valve to prevent the wind turbine from draining the battery.
Up to 1.6 amps
We use the amp meter function on a Klein Tools CL2000 multi meter. Connect the power cable to the battery and run the red positive lead or leads through the center of the orange clamp. The amps are measured with an electronic field. Do not connect the alligator clamps to anything while measuring amps.
The great thing about charging 12 volt batteries is you can power anything with a 12 volt plug. Say you’re at Burning Man where there’s a bunch of wind. Set one up at camp to help power 12 volt fans, air pumps, lights, personal electronics and toys of all kinds.
With other turbines you need a tower. Towers work great but it's nice to have the option to quickly install on existing structures with a few screws. Experiment at different locations to see where the wind is strongest.
Most other wind turbines are much larger and the spinning blades are a hazard. Our wind turbine systems are super compact and highly portable. Our blades are small and light weight which makes them safe from up close testing.
