    Future of Drivetrains, No Gears, No Chain.

    This may not be as simple though as latest quantum mechanics experiments have shown. :)

    Future of Drivetrains, No Gears, No Chain.

    Actually light can be both particle and electromagnetic wave. This is quite a complex area of physics :)

    Heat can transfer by 3 means Conduction (contact with a material) Convection (fluid movement) Radiation (electromagnetic waves)

    No, it radiates, with a Radiation intensity of colossal proportion :)

    Under the sea is very different as you have water to conduct the heat. The problem in space is that there is nothing to conduct heat, which makes it very poor for cooling.

    The transition

    Heavy sight ....

    The transition

    Well some of what is going on has potential exponential scenarios, and once on an exponential phenomenon, extinction is very possible. The planet already went through 2 of them and they only involved natural disasters ...

    The transition

    Whether because of ecological disasters of our own making, or civilization collapse from infinite stupidity greed and selfishness, we are hopefully headed for extinction, and a better specie can emerge in a few million years :)

    The transition

    Well you can always find the justification you are looking for. I went solar and EV a little over 6 years ago. Produced 62MWh, almost 10MWh per year. It covers all my electric bills and that is including AC and 2 EVs. No electricity and no gas to buy for 6 years. With how the price for these...

    I think if an automated gear change was able to maintain the right pressure on the pedal when maneuvering on tricky terrain, I would not care for the manual gearing as it would allow to focus on the bike handling over the obstacles. Now it remains to be seen if one of these systems will get...

    Looking for details on the eCVT technology announced in the Avinox and Gobao motors, I found the french video below on the first integrated eCVT motor to come out, which was the e2drive owuru motor on the Decathlon ebikes in 2023. The owuru motor definitely does not have as good specs power...

    Matter of personal appreciation. I found a very crude enviolo with harmony automatic shifting a decent approximation for city riding :) I am sure the system we discussed are far more advanced, so are already good enough for a lot of casual riding where people just want to enjoy their ride. Now...

    No argument that the automation will rely on many factors (especially the SW) and will have to be proven for every usage scenario. Road use scenario being much easier to solve than agressive MTB riding.... But even if you use the bikes in full manual mode, it makes for a much better bike and...

    I was answering Stephan. I deleted the original post and reposted as a reply so it was more clear :)

    So no answers, just religion :) Thats OK, religion like taste and colors are a matter of personal preference....
