They said the tetger would be 36,000 km. 36,000/200kph = 180 hrs... 180hrs/24hrs/day = 7.5 days. Why the tether needs to be 36,000km long wasn't mentioned.

Concur 100%. This story is just another indicator of a decades-old deeper global corporate philisophical crisis that's leading the global economy down a deep dark rabbit hole. Please see my comment; I feel strongly that this is an impo

This is not a uniquely Chinese problem - we have the same problem right here in the US... In Tim Oreilly's book 'WTF? What's the future and why it's up to us' (1), he talks quite a bit about the emergence of the ide

Don't worry, most people don't understand the physical infrastructure of the internet. However, from my understanding, a direct connection to the internet backbone is what gives tier q ISP's their God-like monopolizing power

Concur, this comment explained the shape quite simply. From what I see, this is a simply a special case octohedron. Nevertheless, I've been working on an optimal 3D solid packing problem for a hydrodynamic application, and I'm tot

I actually read this document recently for my work on grounding equipment on ocean going vessels. Surprisingly, there is very little in Mil-std-1310 (1) about ground loops on ships. Ships are interesting from a grounding perspective because

Not bad points, but I won't believe youre first statement (Re: "tripling down" on automation) without a citation. The heart of what's going on (good or bad; I tend to think it's bad for society in general) does not

I agree. The ethics policy is certainly set by the CEO, but the public actions that any given leader in the company chooses to make represent that leader's interpretation of the set policy, and these action set an example (i.e. establi

Sorry for the delay. Certainly not a personal gripe of mine, I don't work for PayPal and don't know this person from adam. These were forwarded to me, but similar ethical concerns are growing at my company as well. The fact that t

So what? If people don't want to pay surge prices, they don't have to. Just don't take an Uber or Lyft ride. Ride sharing isn't a human right. If the government wants to step in, maybe they should create a state sponsore

Again, this is incorrect interpretation of the cited paper.

Again, this paper acknowledges the operating principles of an EM drive, but simply argues that the efficiency isn't sufficient to achieve a significant acceleration. "Significance" is relative to the application and efficienc

The underlying principles of the EM druve are very straight forward, easy to understand, and don't violate any laws of physics. The momentum and energy of photons emitted from the antenna (or any antenna) do not exert a reverse force o

H2 fuel is absolutely practical and we're integrating it into designs as we speak. However, we are using Cryogenic Liquid H2 (conforming to IMO IGC(1)) which msy be stored at atmospheric pressure, not compressed gas, although additiona
