<p>Congrats to dstark on building up his INTC position.</p>

<p>How about gluttony? I could come up with a bunch of stocks in that category pretty easily.</p>
<p>Amazing…</p>
<p>There has to be an investment opportunity someday.</p>

<p>BCE, do you mean DNKN, KKD, CAKE?</p>
<p>Dstark, I’d feel like a dollar bill shoved into a container travelling through a pneumatic tube. There are no windows so not good for the claustrophobic.</p>
<p>I don’t know how our body can stand the acceleration. It looks like the minimum acceleration to produce the speed would be more than 300 times free falling.</p>
<p>Here’s my rough calculation. NY to San Fran is about 5000 km, so the average speed to get there in about 45 minutes is about 6666 km/hour. For 1G acceleration, if my calculation is correct, it takes about 31 minutes to accelerate to that speed (6666k / (360 * 9.8 * 60)). I am not sure if we can stand constant 2G, but if we can that would bring the time down to 15 minutes range to accelerate to that speed. Conversely, you need the same amount of time to decelerate, so the top speed needs to be more to get the overall time down to 45 minutes.</p>
<p>Too early in the morning to put my brain to work, let me try. Accelerating 9.8 m/s for 31 minutes equals 9.8<em>31</em>60=18km/s or 65,000km/h or about 40,000mph. 4000mph is doable. I take back my earlier post #7849.</p>
<p>We can’t build a pipeline for fluids that doesn’t leak, but now we around going to build a 3000-mile pipe that is at hard vacuum?</p>
<p>That article says it could follow the interstates… you couldn’t take the turns on the interstate at 4000 mph without the g-forces squashing you. A car traveling at 60 mph around a 2000 foot-radius curve generates about 1/10 of a g in lateral acceleration. At 4000 mph, this would be over 500 g’s. Splat.</p>
<p>Plus we don’t have materials strong enough to withstand this.</p>
<p>Acceleration:</p>
<p>v = a*t + v(0).</p>
<p>Assuming v(0) = 0 (i.e., we start from a dead stop) and we accelerate at .5 g:</p>
<p>4000 m/h * 5280 ft/mile * 2.778e-4 h/sec = 5867 feet/sec</p>
<p>5867 ft/sec = 16 ft/sec^2 * t</p>
<p>t = 366 seconds or about 6 minutes.</p>
<p>1/2 g is sports-car acceleration. You can handle it for 5 seconds, but 6 minutes? 1/2 g for 6 minutes might hurt or kill people.</p>
<p>The turning around curves, even a very small one at high speed, is really a good point, not sure how we can stand that. But a sports car going 0-60 in about 5 seconds is about 5+g on average based on my calculation. 1g would be going 0-60 in about 25+ seconds, I think we can stand that for quite a long time, we all do that almost every day without any problem. Not to say that this is quite wild and challenging proposition to make it safe and reliable, tunnel has to be straight as an arrow from point to point and anything goes wrong and you want to stop, you better have at least 5-10 minutes to slow the thing down or you’ll most likely be brain dead.</p>
<p>^ Your math is way off.</p>
<p>60 miles/hour * 5280 ft/mile * 2.7778e-4 hr/sec = 88 ft/sec</p>
<p>v = a*t
88 ft/sec = a * 5 sec</p>
<p>a = 17.6 ft/sec^2</p>
<p>1 g = 32.2 ft/sec^2,</p>
<p>so the sports car accelerates at 17.6/32.2 g, or about 0.55 g.</p>
<p>0-60 m/hr at 1 g takes 2.7 seconds</p>
<p>0-60 in 25 seconds is about 0.1 g. </p>
<p>You are off by a factor of 10 somewhere.</p>
<p>At 5 g’s it takes 36 seconds to get to 4000 m/hr. The biggest roller coasters can generate 5 g’s for a very brief time. 30+ seconds would hurt and/or kill some people.</p>
<p>Umm, 1/360 = 2.7 e^-3. :)</p>
<p>^ That is true.</p>
<p>However, there are 3600 seconds in an hour, not 360.</p>
<p>Ahh…, what an order or two of magnitude between fellow posters…</p>
<p>I hear the rocket launch into space is 3G plus, and that sustains for more than a few minutes for the astronauts.</p>
<p>Close enough for government work. :D</p>
<p>Uhhhh… This is a private sector proposal and the proposal looks unworkable. Lol</p>
<p>What is a realistic speed that people can travel long distances without dying?</p>
