I still don't understand why Google and Sun are offering the same software under different names. Google is backing the Mozilla Foundation while supporting their own Chrome (read: they didn't write Firefox, just back it), and Sun is distributing both OpenOffice and StarOffice.

What are you saying here? That Chrome and Firefox are the same software?!? What you're saying about Sun seems right, but Chrome and Firefox aren't close at all...

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

  • If we're not coming up with something new and innovative we're stuck making outlook clones. People don't like writing software like that.

What are you talking about?? Writing clones of commercial software is the prime directive of open source! I'm going to go out on a limb and say that actually there are quite a lot of people who like nothing more than doing exactly that.

Heh. I guess so, though by that logic EVERYONE IN THE WORLD should be wearing a paper bag right about now.

It might be interesting to see all those people bumping into each other, but I guess it wouldn't add that much to the Linux development effort.

Aw, who am I kidding. Bring on the bags!
