    Or just skip all these "inventions" and keep refining the diesel engine.

    A few things come to mind.

    1) AFAIK, we can't just stop making "unleaded" and start making twice as much "diesel" fuel. The refining process isn't overwhelmingly precise and controllable. If it was, we'd simply get rid of the bunker oil & tar, and make more fuel.

    2) The development of fuel cells which can operate directly on gasoline looks like the only possible way for combustion to move forward in the medium-term. Already, fuel cell efficiency is about double ICEs, and well in excess of diesel engines as well (eg. 60% versus 30% for ICEs). But they do NOT operate on diesel fuel.

    Secondly if a Battery like device was used for this it would be inclosed and probably nicely insulated

    I'm not aware of any insulation which can handle such temperatures. You're probably looking at a ceramic casing, which needs to be very large, and then a large layer of insulation. It's dangerous if the ceramic material ever cracks, and not to mention any combustion process will need to exchange heat and oxygen, so it seems unlikely to be a sealed device, like a battery, no matter how large. It might be possible to include oxidizers, a LOT of thermal mass, and then seriously restrict the energy output, but that's quite a stretch at this point...

    My UPS has battery test (checks if the batteries can still be used, if it fails, batteries need replacing) and run time calibration (discharges batteries to 25% and monitors how long it took, based on that it can estimate how long will it be able to hold the load).

    Yes, but you HAVE A UPS (an APC Smart-UPS by the sound of it). Google does not. They have SLA batteries hard-wired into the PSUs of each individual server. Now, it would be possible for there to be special circuitry to do an online battery test inside the PSU, but considering Google's focus on extra cheap commodity equipment, and redundancy as the answer to all problems, I fully expect that they've forgone the extra circuitry needed for such features...

    The whatever system google is using should be able to check the batteries while power is on, so that you don't end up with batteries that have 20% of their original capacity when the power goes down.

    "should" is a strong word, and this could very well have been the issue.

    They may have decided that swapping batteries after X years, or Y power outage events is accurate enough to forego tests, and the number of exceptions (early failures) is small enough to make this a viable strategy. Doing spot-checks in addition to this would make this an even better strategy, still.

    Battery tests could be performed by automatically instructing various PDUs to power-down 1 out of X units, or racks, preferably in a round-robin, or least-recently tested first. Knowing that each battery should power each system for, say, 15 minutes, any which aren't up and running 10 minutes later should be pulled and replaced. Additionally, on-board circuitry monitoring voltage could be used as an indicator that the battery is likely at 100% capacity (over 12.5V) 50% capacity (~11V), or nearly dead (below ~10.5V).

    How often these tests take place would depend on how many servers Google is willing to put at risk at any one time, and perhaps even how much of an impact powering off/on a large number of systems at about the same time would have on their in-house circuitry, and upstream power provider...

    For some perspective that is about the heat that a filament in a lightbulb is at.

    That doesn't provide MUCH perspective... A lightbulb is a completely enclosed environment, and the filament won't last for a moment outside of it, so people don't really know just how how hot it is.

    Now, saying 3,000K is about the temperature you get from a metal-cutting torch, actually gives some better insight. For one, it's instantly clear that it would easily melt just about all metals. For another, it's eminently clear you don't want it anywhere near you, and it will require significant insulation.

    Sure, maybe if you know that lightbulb filaments are made from tungsten, tungsten has the highest melting point, and that they run close to that melting point, you could figure it out, but that's a bit of a long shot, and such a stretch certainly indicates it didn't provide the perpective claimed. At that point, it's probably be easier for someone to convert the units to celsius, and just search for that temperature to find appropriate comparable examples.

But I guess none of this matters in your imaginary world.

    Work on Theora started in 2002, work on H.264 started as early as 1998,

    In 2002, VP3.2 had already gone through the full life-cycle, it was a mature codec sold as a commercial product, and had long since become obsolete to VP4, and VP5.

    264 has been in the works for a long time and the patent holders had a long time to drum up support. They wanted a piece of the pie for MPEG 2 successor, so they made sure H.264 would be it.

    No, they wanted MPEG-4 ASP to be the successor of MPEG-2, and they failed miserably. H.264 was designed for low-bitrate applications, which is something MPEG-2 has always been horrible at. H.264 was also intended mainly for your cell phone, not broadcast. The fact that H.264 is catching on elsewhere is a surprise to all involved.
