I'm sorry, but I agree with that. If you on the UK want us to dam up our rivers and build roads out to geothermal areas and tap into our resources, and raise our local power prices in the process, all for the benefit of the UK, our government better damn well profit as much as possible from it and reduce our taxes / improve our services in exchange for that.
Unfortunately, xB and xD do not agree.
Readily replaceable intakes?
Seriously, fuck the fish.
Better negotiate the contract during a Sjálfstæðisflokkurinn / Framsóknarflokkurinn (conservative) government. Samfylkingin would approve it under the condition that the Icelandic government's share of the sales are so high that you would barely save any money on the imported power, and Vinstri Grænir would outright reject it no matter what you offered. But Sjálfstæðisflokkurinn and Framsóknarflokkurinn would let you dam up whatever rivers you want and take gigawatts of power in exchange for a handful of shiny trinkets and a couple magic beans.
nope. They can block IR thermal cameras, but 99.987641% of all security cameras are not the multi thousand dollar FLIR type camera.
a $1.00 pair of mirrored lense sunglasses will also do this. Sorry AVG, your best and brightest are way behind the curve.
If you want to make their version, buy retroreflective tape and apply to your face or a set of cheap sunglasses.
Yep, That is why anyone that is not aggressively paying off all the debt they have right now is a complete and utter fool.
I have friends that are buying new cars, etc... They are morons, raging morons... "but it's 1.2% ITS FREE MONEY!" they forget the loan origination fees they pay or are tacked on the loan... Oh that $35,000 car loan has a $1900 set of "fees" on it.... But we dont count that as part of the interest rate...
If you are having a time of prosperity, PAY DOWN ALL YOUR FUCKING DEBT! Because the next crash will come around sooner than you think because the banks are doing the same shit again.
Banks need heavy regulation put back on them. I also suggest we have a Bank police that goes around tazing executives at random if we even think they are thinking of anything "clever"
People who don't care about music quality. Or those of us that need a set that packs up easily in the work bag and does not take up space.
I have listened to $300 earbuds and they suck compared to even a $40.00 set of real cans, It's why the junky "beats" headphones became popular, a lot of people tried them and said "wow these are amazing" compared to earbuds.
One advantage of earbuds is that they do not do any real noise isolation so you can hear when a bus is about to squish you. Good headphones will keep the sound of that bus out of your ears even after it hits you...
And how do we know that the real benefit doesn't come from hitting yourself with birch branches?
zblockquote>See: Cabin_Pressurization [wikipedia.org]
A person needs at least 20kPa *from the mask to breathe*. Not 20kPa *ambient pressure*. Please learn to read.
The "problematic loading on the capsules" is from the high speed aerodynamics, not the ambient pressure
Aerodynamic loading = pressure. If you have high loadings, you have high pressures. Period.
Are you talking about what I was talking about? I was talking about an electric motor, not a fuel-driven one.
What sort of claim is that? Since when do oxygen masks need 20kPa to function? And secondly, if there's "problematic loading on the capsules" from too much pressure on the pressure-compromised capsule, then your pressure is also way too high inside. Which means that you've repressurized the tube way too much. So the solution is: Don't do that!
Branching at full speed is probably not possible with the Hyperloop as designed; the skis are curved to match the diameter of the tube, with a ~1mm clearance with the tube surface, so there is no passive tube design that could accommodate a "switch". In order to continue from Section A to either Section B or Section C, you'd have to make an intermediate length of tube several hundred meters long that could be physically moved at one end from B to C, with sub-millimeter precision
Wait, meaning that while it's technically possible, but it'd be really tricky to accomplish? Gee, I wish I had written something like "Branching would be really tricky, but there's no physical barriers" at the top of my post
The reason is threefold: drag continues to increase at higher speeds regardless of the speed of sound
Drag is reduced in the first place by using hydrogen even at a given pressure. And you can use 1/4th the pressure and still maintain lift because you're moving four times as fast. And given how few reboosts are needed from LA to SF in the base case, a few more per unit distance hardly seems limiting.
If you consider that the steel Hyperloop pipe draped across 30m-spaced pylons will approximate a vertical sine wave, then at 700mph the allowable sag is only about 5cm
Irrelevant because earthquakes impose far more deflection that you have to be able to counter (and that the proposal calls for countering) than a craft moving past.
Mechanical braking from 1500mph in the event of an emergency is also a non-starter
What, you're picturing drum brakes or something? You're moving at high speeds in a giant steel tube. Magnetic braking couldn't possibly be easier.
a 700mph capsule will incur about 2g's of aerobraking deceleration
Where are you getting this from? Even if the tube was instantly full pressure (which it wouldn't be), a streamlined shape will not experience 2Gs at 700mph, any more than a passenger jet losing full engine power does. And anyway, 10g horizontal is not fatal even if that was the case. The average untrained individual, properly restrained, can tolerate 10g for a minute without even loss of cognitive function.
Not only that, but if your craft is travelling four times as fast, you're sweeping through four times as much gas per unit time to compress under the skis.
Hydrogen has all sorts of advantages. And the very low pressures prevent most of the negatives. The only one that I don't know about and would require testing would be what sort of reaction would one see as a craft moves past, with any residual oxygen. If I had to guess, I'd guess that you will get some combustion, but the craft moves past so fast and the mixture will decompress so fast, I would think the rate would be quite limited.
First off, if servicing that requires full de/repressurization is some sort of frequent event, then the whole concept is doomed for reasons entirely unrelated to anything in this discussion. Secondly, 1/5 ton of hydrogen at industrial rates is about $200. Whoop-di-doodle-doo. And the advantage is being able to travel at mach freaking 4, not about the reduction of drag at a given speed (which is, FYI, true also).
