Against the open sky
Whisper-quiet on the rooftop. Turn the sound on.

See GIVARA ONE for yourself.
GIVARA ONE is the rooftop wind turbine we are building to make electricity. This is real footage. We add new clips as the work moves.
On the roof
GIVARA ONE turning on a real Indian rooftop.
The sun is low. Solar is resting. GIVARA ONE isn’t.
Filmed in the dim light at the edge of the day, and still spinning fast.
The whole machine
Three outer blades around the blue inner rotor, above the city roofline.
Put to the test
Real tests, shot in one continuous take.
Wind sensor barely moving. GIVARA ONE still turning.
So the next gust never finds it at zero. Built to catch wind from any side and speed up early, it spends more time making electricity and less time sitting idle.
95 RPM, read by laser
20% faster than our August machine. Same bench, same fan at 4 to 4.5 m/s, no generator attached. One take: the machine, then the laser meter reading it.
79 RPM, read by laser
Our first machine on the bench, workshop fan at 4 to 4.5 m/s, no generator attached. One take: the machine, then the laser meter reading it.
Our own generator
Coils wound by hand. Built in-house for this machine.
Our own generator, first version
Why our own, when the market is full of them? Because GIVARA ONE needs one made for low speeds, to get the most out of even a light wind.
Our coils, joined by hand
The team soldering the hand-wound coils of the generator ring.
How we built it
From the first blades to the first spins.
The full machine in its test rig
Assembled and at speed, inside the steel rig.
The outer blades, spinning
An early spin in the workshop, before the inner rotor went in.
Outer blades on the mast
The white outer blades on the mast, spinning in front of the workshop blower.
