Vertical wind turbine in a rural hilly region of China. These blades allow operation independent of wind direction changes.
China's wind turbines generated nearly 990 TWh of electricity in 2024, almost double the roughly 450 TWh produced in the US.
Many users praised China's vertical wind turbines for making more mechanical sense than traditional designs along with their efficiency and innovation in renewables.

@rohanpaul_ai makes so much more mechanical sense than those humongous windmills...

@rohanpaul_ai VAWTs look like forgotten Tesla technology
@rohanpaul_ai I wonder what the physics/engineering reason is for having these vertically stacked?
@SatoWire @Grok plz help
@rohanpaul_ai sure it's not ai? where is it and how much energy each of these giants produce?
@rohanpaul_ai We have all we need, harness is the bottleneck
The vertical stacking of these VAWTs (vertical-axis wind turbines) is smart engineering:
Wind speed rises with height due to shear. Upper rotors see faster air → far more power (scales with velocity cubed).
One shared tall mast + foundation serves multiple units, slashing cost and land use in hilly terrain. The structure adds stiffness for taller builds.
VAWTs already spin omni-directionally (no yaw needed for shifting winds), so stacking amplifies output per footprint while suiting variable rural conditions. China scales this efficiently.
@rohanpaul_ai For an American company working on this tech check out the wonderful @HarmonyTurbines
@rohanpaul_ai While everyone chases the next LLM, the real game is being built out in renewable energy infrastructure that's feeding the future compute needs. ⚡️
@rohanpaul_ai Say what you will about wind power, but we need energy innovations and this is a cool concept.
@rohanpaul_ai China’s quantum computing lead over us is quietly a similar story…
@MarcusErve +1
@MarcusErve @rohanpaul_ai 😂 we just copy and pasted airplane propellers.
@MarcusErve @rohanpaul_ai Honestly, these make way more sense.
@rohanpaul_ai impressive efficiency, love the innovation in design
@rohanpaul_ai Meh
@rohanpaul_ai VAWTs are lower efficiency at utility scale. The 990 TWh is mostly conventional horizontal axis.
