"If the car is a hybrid it's simply less efficient than diesel at the moment"
Hello, why not hybrid diesels? The two technologies are not mutually exclusive.
I believe GM is working on a vehicle which uses the engine to power the batteries only (no drive train), thus allowing the engine to run at peak efficiency (vs. running at various RPMs). I can't remember if the engine (generator) is diesel or gasoline - but it'd be a perfect candidate for diesel.
Not so - the three SSMEs put out around 1 million pounds thrust - the SRBs put out over 7 million. Efficiency is one thing - brute force can count for quite a lot.
Although Carmack is throwing away lots of efficiency by bypassing convergent/divergent nozzles, he is gaining ease of manufacturing (somewhat). But, he still has to deal with cooling, which involves either using an ablative material, or else some sort of regenerative cooling (using a liquid [usually cryogenic] circulated inside the nozzle to keep it from melting). And that is one of the major factors in complicating nozzle design - not the curve or shape of the nozzle.
What's he using for turbopumps - and injectors? Nozzles are probably the cheapest part of a liquid engine.
Has Microsoft ever considered repositioning themselves from a Windows company to a software company?
Instead of fighting Linux, Java, etc., Microsoft should embrace them. Instead of trying to dictate what the customer uses, foloow their lead.
Face it - Microsoft will never kill Linux. But, there's potentially a lot of money to be made supporting it. Imagine a Microsoft bundle of Linux - with Microsoft support. You'd get a lot of business you'll never see otherwise.
Then, consider the concept of cross-platform software. There's really no reason why Word isn't available on more platforms than just Windows and OS X - why not Linux as well? If you write your core software platform-neutral and wrapper the UI nicely, you'd gain market share for very little extra costs.
If Microsoft was more open to this sort of thing, I think people would be as hostile to the company. Right now, every thing you guys do is so tighly bound to Windows you alienate many folks who otherwise might be customers.
I personally don't like Microsoft or Windows - until I got my new box with hyperthreading, it was possible to a single program to lock up the box by maxing out the CPU, and I'm not impressed with the stability or security - but I DO have a Microsoft keyboard - because it's the best I've ever used.
People WILL buy a product if it's simply the best. But if it's shoved on them as a result of market monopoly (and the quality is only moderate), they'll look elsewhere.
