Meet Our Turbine
Rooftop wind energy of tomorrow, today.
Made for Cities
Our wind turbine solves three major problems blocking widespread adoption of rooftop wind turbines:
- turbulent wind
- dangerous blades
- visual pollution (spinning blades are obnoxious)
Our turbine solves all three problems by enclosing the blade in the shell, turning a hazardous environment on its head and actually using it to generate more power than other turbines all the while doing it quietly, safely, and effectively.
How it Works
Cities are no place for regular turbines. Turbulent air and changing wind directions can cause regular turbines to shatter or catch fire.
Our turbine turns this hostile environment into exponentially more power than a regular turbine of the same size. All while operating quietly and unseen behind a shroud.
This is done by a few different methods all of which are proven by hundreds of years of science and experimentation. We've just reimagined that science in a way that let's you generate rooftop wind power safely and quietly.
The Science
Bernoulli's Principle
This is a key concept in fluid dynamics that relates pressure and velocity of fluids (air is a fluid). When wind encounters a building, it builds up positive pressure along the face. Incoming wind avoids this by moving upwards towards the roof, where a low pressure system forms. High pressure pushes while the low pressure pulls, forcing incoming air to concentrate and accelerate. Wind power is highly dependent on speed, turning the building into a major advantage.
Venturi Effect
The Venturi Effect is a real-life application of Bernoulli's Principle. This happens when the now the accelerated and concentrated wind meets our turbine on the roof. The fins collect incoming wind and funnel it into the enclosed blade, further concentrating and accelerating it. Again, more speed, more kinetic energy. This is a well-understood and proven concept. Kinetic energy is increased at the expense of pressure potential energy, conserving total energy.
More Power
Power generation in wind turbines is governed by the equation P = ½ρAv³. As velocity (v) increases, power increases cubically (v³), meaning velocity is the king of wind power. Remember the previous two steps both increase wind speed (as well as concentrate air). That means exponentially more power than an open bladed turbine can generate. This exponentially increased power outweighs any potential tradeoffs of the shell.
Expected Specs
While the turbine is still in final development, we're starting to hone in on the final numbers. We expect the first turbine to be roughly inline with rooftop solar costs per watt.
This means that customers will be able to pick and choose wind vs solar based on their site, not on budget. A building in Arizona should have more solar than wind, while a building in Chicago may need more wind than solar.
This is for a large commercial turbine for rooftops on warehouses, grocery stores, industrial buildings, offices, etc. A smaller residential version is planned alongside or shortly after the commercial version. Due to its smaller size, the residential version will most likely be more expensive per watt than solar.
Still In Development
We expect the turbine to be available Q4 2026.
Our turbine is still in development with expected sales in Q4 2026. The hard part is done, though. We've created a novel rooftop wind turbine from just an idea and it took just over 3 years to accomplish.
The task ahead is to turn our turbine into a manufacturable product, build a few prototypes, and test them for a few months before a controlled rollout the market.
We still have some milestones to hit and hurdles to leap over, but we're backed by a community of over 40,000 people and we won't let them down.
