ROOFTOP WIND
Power when solar can't.
Halcium is building a rooftop wind turbine so buildings can make power at night, in winter, and in storms.
The problem
Night, winter, and storms leave a gap. Rooftop wind could fill it, but today's turbines have open spinning blades, flicker, and struggle in messy city wind.
What we're building.
The blades sit behind a stationary shell. That is safer for people and wildlife, and it cuts the flicker. The shell and the building are meant to speed the wind up before it reaches the blades.
Where We Are
Engineered design targeting 11 kW rated output in 11 m/s ambient wind speed. Proving the turbine in the real world with a built prototype is up next.
Why It Matters
A roof that makes power around the clock means more energy security for the building and a stronger grid. Diversifies urban grids away from just sunny summer days, producing complimentary power at night, during storms, and cloudy winter days.
