    As someone that has had to do these calculations professionally, I was disappointed until the load sensor was added. re the GPS. The distance could have been done using the cable length/your paper wheel etc but hey. I am glad you added it to check the dyno calculations as those 2 metrics are far simpler to calculate HP than the dyno and all its parasitic losses.
    Regarding James Watts calculations./estimate. You need to keep in mind that his calculation is the average power he observed over many hrs ( and for good reason because its all about "work done" ) So whilst Big D produced 5.7Hp in that burst, thats not what James Watt was referring too. His comparison is to his engine that is expected to produce that power ALL DAY. So I think he is probably closer than you might think.

    Watt was interested in pitching his machine to people who had horses work for hours on end, everyday, on critical infrastructure like a mine's water pump.
    What you measured was Maximum horsepower output. Even a strong modern horse wouldn't be able to pull their full strenght for much time. What Watt did was find out the load in which the average horse could pull continuously.
    And the French repeated his experiments, but they did it on the Metric system. A CV is roughly 10W less than an HP. Which is pretty much right on the money if you consider the statistical deviations between the horses tested.

      The horsepower was never intended to measure peak output, that's a modern car thing. It was for measuring the expected amount of work you could get out of a horse vs. some motor or other, and after we stopped using horses it stopped mattering all that much how accurate it is. So, a relatively relaxed horse descended from draft horses is exactly the measure we want if we want to know how much Watt was fudging his numbers to make his steam engine look good.

I think it speaks more to the incredible engineers who have gone from GIGANTIC steam engines that make meager power numbers all the way down to tiny little electric motors that generate horsepower sometimes in the triple digits is far more impressive. The way they can design something to be so small yet so effective at generating power is truly incredible

      I always knew James Watt came up with the horsepower rating. I never knew how he did it though. What people have to realize is it is an average over time. Sure the horse pulled 5.7 HP on its pulls but it has to sustain that kind of effort indefinitely. An engine can and will run all day long. It wasn't brewing where horses were being used either but mining. Mines had to have large stables for their operations. It was an enormous expense to maintain. The financial incentive to get rid of all of that was huge. Everything had to be pulled out of mines. Which included a lot of water.

      He never base tested with a car!
      We don’t have a way to verify their calculations. If we want to be scientific, yes all this works, but at least compare the linear drag Big D could make with that of a car that you have verified the horsepower with the same dyno before, to make sure the calculations are correct, yes the calculation’s results made sense, but it wouldn’t be that hard to just hook it up to a car to see if the power lost is equivalent to the calculations. Always have the base comparison tested the Same Way! otherwise good video, and inspiring :)

      I don't think this experiment has any potential to be used in a peer-reviewed study. The mere fact that Big D is nowhere close to the maximum size and power of a large draft horse (like the one shown at 3:10 in the video) the potential for alternate outcomes in results is too high to warrant consideration as proof of the horsepower produced by the horse as a species.

      As I scientist that often does peer reviews, I would have a lot of concerns. Using only 1 horse already makes any publication impossible imo. Let alone that the set-up is unnecessarily convoluted allowing for a massive amounts of errors. Furthermore, as stated at the start, horsepower was based on the power of a horse over a long period of time, not peak horse power. These ‘errors’ all make sense for this great video and this really isn’t a critique. But calling it science worthy of publication is a bit of a stretch 😅
