  1. Re:my cloak of invisibility... no make smart does. on Tanks Test Infrared Camouflage Cloak · · Score: 1

    I didn't want to invoke Godwin and was specifically avoiding WW2 - but you just proved my point for me. The King Tiger was over-engineered. While it was the only tank that could kill another tank from well over a mile away, and while it brushed off direct frontal and even side hits from T-34's and Shermans and - as you correctly acknowledged - was only vulnerable from the rear (and from the air), it weighed so much it could barely move, it had constant gearbox and engine troubles because of this, and even worse - it became hard to find bridges and roads that would take its weight - further limiting its area of operations.

    This proves that engineering and technology can eventually lose sight of the forest while designing the ultimate tree. Now fast forward to today's scenario where the only real threats to America in a conventional military sense are China and Russia. The Russians tended to favor quantity over quality back in the Soviet/Warsaw Pact days. Today it seems that they have chosen a technological route similar to the US - or they can't afford/aren't organized enough to field as large a standing army as they used to. But the Chinese have proven themselves to be masters of mass production par excellence. They have the added advantage that their population is double that of Russia and the US combined. Such a population allows you so much cannon fodder that you can simply absorb the enemy's ammunition before launching your counter-attack. All they need is a good gun design and numbers, and then it just becomes a matter of time. In this philosophy survival of my tank is irrelevant - its killing enough of yours to make you ineffective, at which point I still have tanks left and win the day. Their losses would be tremendous, however the scoreboard in war was never kept by body-counts but rather by who is left standing on the valuable political or economic stuff at the end of it all.

  4. Re:Tanks are old school. on Tanks Test Infrared Camouflage Cloak · · Score: 1

    You had to go back 100 years? Tanks were brand new and no one know how to fight them, or how to fight with them. Nowadays tank-killing can be extremely cheap and cost-effective in the right terrain. A couple idiots with RKG-3's are much cheaper than a modern helicopter and a pilot who had to be trained for years, or a tank that had to be manufactured and shipped across an ocean or two. Like it as not, Iraq and Afghanistan are teaching the world that it's possible to survive against a modern army - but not by facing it head on. As always - find the weak spot and push...

    While a troop of super technological super stealthy tanks yields a great tactical advantage, this advantage is absolutely neutralized when your enemy can manufacture 50 not-so-good-but-good-enough-to-kill-you tanks to your one. All you need is defense in depth and eventually the numbers work in your favor. The US always seeks out an expensive technological approach to try to solve problems. While this can work sometimes, it sometimes results in hundred million dollar state-of-the-art planes that can't fly.

  14. Re:Energy != work on Tapping Subway Trains For Energy · · Score: 1

    IANAElectrician, but if you're storing the power locally couldn't you isolate sections of the track from each other and the grid in general and have an "acceleration" track to avoid what you describe? The connection with the rest of the rail could be broken when a train is about to leave, and the flywheel + grid is fed into a predetermined length of isolated track. The train accelerates with power from the flywheel (plus some grid) and crosses onto the main track via inertia but since it's at speed already the current draw is not that much so there shouldn't be a huge change when the train switches to the main track. Likewise the decelerating train leaves the main track and pumps energy back into the flywheel system only, not the whole network.

  16. Re:Regenerative braking? on Tapping Subway Trains For Energy · · Score: 3, Informative

    Electric motors draw maximum amps at the very beginning just before they start turning. After that the draw is significantly less because resistance increases. You know, V=IR rewritten as I = V/R. The voltage is fixed, the resistance is close to zero when the motor is not turning so the amps go sky high. But only for an instant. As soon as the motor starts turning resistance picks up due to electromagnetic effects and the current draw falls. This is why you'll burn out a motor switching it on and off too quickly. You're shooting tremendous amounts of current through a non-turning motor. All that huge amount of current heats up the coils until something melts. However the 10,000 amp figure is peak, not continuous for 30 seconds. Therefore it's not fair to use that figure for calculations over a 30 second acceleration period. The amps drawn would form a curve, and for that you'd need something a little more complex than y = mx+c to figure it out, ie knowing the exact curve for those engine types/trains and some calculus.
