Lol:

The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.

However, it delivers a jaw-dropping 750 kilowatts of power, which is the equivalent of 1,005 horsepower.

I feel like we’d need peak horsepower output of a small dog to truly understand this.

A dog’s power output comes from its muscle mass, which for a healthy dog is about 45% of its total body weight. This gives our 28-pound dog roughly 5.7 kg of muscle.

Studies of animal muscle show that the peak power output of vertebrate muscle tissue during a short, explosive burst (like a jump or the start of a sprint) is around 100 to 200 watts per kilogram of muscle.

Now we can estimate the dog’s peak power:

  • Low estimate: 5.7 kg of muscle x 100 W/kg = 570 watts
  • High estimate: 5.7 kg of muscle x 200 W/kg = 1140 watts

Converting these figures to horsepower (1 horsepower = 746 watts):

  • Low estimate: 570 W / 746 ≈ 0.76 horsepower
  • High estimate: 1140 W / 746 ≈ 1.5 horsepower

So, a small 28-pound dog might be able to generate a peak power of around 0.75 to 1.5 horsepower for a very brief moment.

So this YASA motor is somewhere between 670 and 1,340 times more powerful than the dog it’s being compared to in weight. That’s some jaw-dropping power output.

Stop burning the planet down to generate social media comments about shit you don’t understand
If I’m not mistaken, you very specifically asked for help to better understand this.
  • That was a joke

  • Stop fucking use AI, or at least get used to a sizable portion of people to tell you, that you’re burning the only planet we have down over shit that doesn’t matter.

  • If It makes you feel better (or at least more educated)……Based on recent energy consumption data, the entire three-prompt interaction to calculate dogpower consumed roughly the same amount of energy as making three Google searches.

    A single Google search uses about 0.3 watt-hours (Wh) of energy. A typical AI chat query with a modern model uses a similar amount, roughly 0.2 to 0.34 Wh. Therefore, my conversation used approximately 0.9 Wh in total

    For context, this is less energy than an LED lightbulb consumes in a few minutes. While older AI models were significantly more energy-intensive (sometimes using 10 times more power than a search) the latest versions have become nearly as efficient for common tasks.
