Comment Re:No fuel? You still need power. (Score 3, Interesting) 428

The article mentions a wind turbine as a mean for "harvesting' the energy from the air-currents. In principle it might even work. Sail-ships are fuelless vehicles capable of circumnavigating the globe (although conversion from wind-power to the vehicle's propulsion is much more straightforward).
Practically? I am really skeptic. Gut-feeling tells me that the turbine-battery-compressor cycle is not efficient enough for self-sustained propulsion.

Journal Journal: Problems with SCO IP License for Linux

Here is a list of problems I have with the SCO IP License for Linux (SIPLL). I'll update this as I get angrier.
  1. It's vaporware. There are lots of press releases and documents about the license, but no actual description of what you're buying. I.e. what are the terms? What do you have to agree to? The only way to buy it is to call SCO at 800-726-8649. Hey, SCO, if you want me to even consider buying a license, post the EULA! I'm not gonna shell out money when I can'

Journal Journal: Complaints about the DMol software from Accelrys

This journal entry is a work in progress.

DMol3 is quantum chemistry software that calculates properties of molecules and crystals using density functional theory (DFT). It's currently sold by Accelrys. The version I have used is part of the Cerius2 software suite. Cerius2 is used to build molecules in a GUI and set up a calculation, then DMol3 crunches the numbers.

Journal Journal: Linux is safe from SCO

This is my reasoning as to why the Linux community, especially users, have nothing to fear from SCO.
  • Linux is distributed under the GPL, giving people rights which cannot be revoked by the grantor.
  • "But wait", SCO says, "Linus, etc. didn't have the right to grant that license, so it is null and void." This may or may not be true, but even if it is...
  • But SCO did/does claim the rights to the Unix code, including the right to distribute it under the

Journal Journal: Why Bush pisses me off

This is going to be a record of things Bush has done that tend to piss me off.
  • 2/5/03 - Gee, whaddya know, the proposed budget has a deficit almost equal to the amount of money spent on the divident tax elimination. I thought these Republicans encouraged fiscal responsibility.
  • 1/31/03 - I won't even go into the State of the Union address, where he spends a trillion dollars on political purposes and only a billion on Hydrogen. But an article in USA Today mentions that he lifted

Journal Journal: Man-made meteors possible?

Could NASA create a man-made meteor shower by throwing marbles from the Space Shuttle?
  • Leonid meteors travel at about 72 km/s.
  • A bullet travels at about 1 km/s.
  • Both friction with the air and friction within the compressed air in front of a meteor cause heat. I.e. the meteor feels a friction force much greater than that due to the air density. It "sees" a higher density because it compresses the air a bit.
  • Bill Cooke is a meteor expe
