This sets the upper bound for Lorentz force actuators at around $82 \frac{N}{\sqrt{kg\cdot watt}}$, if the conductor is copper and the magical ambient magnetic field is 1T. There are some clever ways to get around this limit in real motor designs, but that’s a topic for another day.

And I think what we’ve found is when our creatives have a chance to use it, and then they’re able to collaborate with other creatives who are using it and see all the playful ways that they can bring ideas to life, it hasn’t been a difficult tour to get us to get people to adopt. And at the end of the day, it’s all about delivering a better idea. Who knows what’s going to happen with an explosive technology like this? So I don’t want to make too many long-term prognostications because I’ll be as wrong about this as I was about NFTs.。今日热点对此有专业解读
