Firefly is a New VAWT Small Wind Turbine




South Carolina-based Firefly Power is one of 20 other social- or environmentally-inclined companies presenting at the i2i Awards program in conjunction with SXSW Eco in Austin through Friday, October 5, 2012. The company makes lightweight small wind turbines out of carbon-fiber blades in the vertical axis form. The residential unit is rated at 1.8 kW, weighs less than 60 pounds, cuts in at 10 mph winds, and is expected to sell for about $7,000, according to Firefly Power.

Wind energy is a breeze.



When it comes to taking control of your energy generation, you’ve got quite a lot to consider. Solar or wind? How much will it cost? When will I break even on my investment? How dependable are these solutions? Where do I even begin?

We’re here to make it simpler for you. Firefly Power’s wind turbines:
are low-profile, lightweight, and quiet
are simple to purchase — we offer one-stop shopping for everything you need
are affordable and feature all-inclusive pricing
can be set up practically anywhere
are easy to assemble and typically require no permits to install
require little or no maintenance for up to 25 years
provide the lowest cost per KwH compared to other wind turbines
generate power even in a wide variety of conditions, even at low wind speeds

Give your business a tailwind.



There’s a great way to save money, take control of your expenses, and contribute to your community: by generating your own power with a resource that’s infinitely renewable: wind.

The right wind turbine solution can save you more money than solar, can generate energy even on cloudy and lightly breezy days, can pay for itself in just a few years, and can provide you with reliable electricity for decades.

Firefly wind turbines are different because our approach to wind generation is different. We use a new kind of blade design, different blade orientation, and lightweight, super-strong, super-durable materials — which means more power at a lower cost.

Firefly wind turbines:
can scale to meet your needs; it’s easy to install more, or bigger, turbines
are low-profile, lightweight, and quiet
are simple to purchase — we offer one-stop shopping for everything you need
are affordable and feature all-inclusive pricing
can be set up practically anywhere
are easy to assemble and typically require no permits to install
require little or no maintenance for up to 25 years
provide the lowest cost per KwH compared to other wind turbines
generate power even in a wide variety of conditions, even at low wind speeds



It’s a simple concept: less wind, more power.



But the execution took some doing. We wanted to produce more power in a wider variety of wind speeds and locations. We wanted the turbines to be light enough for practically anyone to assemble and install. And we wanted to keep it all affordable.

We do all that with a novel design that leapfrogs standard approaches to blade shape, materials, and form factor.

Our patent-pending blade design lowers the “cut-in” threshold, generating electricity at wind speeds as low as 16.1 km/h (10 mph).

The turbines are constructed of 95 % carbon fibre for superior strength to weight ratio.

Patent-pending blade technology drastically reduces cut-in speed and accelerates lift.

State-of-the-art carbon-fiber construction results in an exceedingly light, strong unit weighing less than many air conditioners.

Elegantly simple design maximizes efficiency, minimizes physical footprint and visual impact, and withstands extreme weather.

The vertical axis orientation captures multi-directional winds and has less acoustic noise emission than horizontal turbines.

All of our wind turbines include grid tie capability.
