but once its there....why do we need HLVs?  big_smile  :0  smile

#1127 Re: Space Policy » Chinese Space Program? - What if they get there first » 2002-12-31 15:39:26

actually, not so far behind.  their rockets are not so technologically inferior to ours or russian rockets.  and if they want to go into space, i say go!

we'll eventually have to join them, and if they want to give us the push, its great.  again, i highly doubt china will be totalitarian for long, but i dont think with their nationalism, they will simply abandon a space program, especially if they get results.  the apollo program was also ended because of a few failures, like apollo 13.  the chinese have almost 2 billion people, and they arent shocked when a few die, so i dont think a few deaths or failures, however cold it sounds, will stop them.

if the space elevator comes into play, VTOL systems might not be needed.  Spaceplanes could be used to deliver small, urgent items, and the space elevator(s) could be used to deliver larger items.  a spaceplane could launch from any airport, quickly get into orbit, and then land at any airport, maybe even performing a passenger or cargo mission on Earth at the same time. 

This is why I prefer a spaceplane: infrastructure, versatility, and speed  big_smile

what could be used as a coolant to keep the exiting water cool?  any ideas?  using thorium, would the heat be wasted as well?

#1131 Re: Interplanetary transportation » Nuclear Propulsion - The best way for space travel » 2002-12-31 13:40:21

links links links!

in any case, could there be breeder reactors for thorium?  could thorium be used to make nuclear weapons? 

Just have to eliminate all the irrational fears...

#1132 Re: Planetary transportation » maglev - long distance travel » 2002-12-31 12:16:26

maglev doesnt touch the ground, i believe.  its suspended between two rails magnetically...or i could be wrong.

#1133 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-31 11:18:21

youre arguments are fundamentally flawed.  you assume that they cant strike first.  the very threat of a nuclear attack is so great that it makes us take them seriously, especially considering their heavy development of long-range missles.

usually when we back out of treaties, barring irrelevant references to Native American agreements centuries ago, we get the approval of the other country, such as in the ABM treaty.

India and Pakistan have only become more tied to us because of recent circumstances, namely, Al Qaeda. 

We go after countries because we are frightened by the way in which these countries seek to use the weapons they develop, in the Cold War, the missle building was defensive--North Korea has nobody to defend against, thus, their missle building must be viewed as hostile.

#1134 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-31 11:01:04

we want to prevent them from having oil because we want them to adhere to the treaty they signed

and youre pretty naive if you think nuclear weapons dont make a country a world power--at the very least, it gives them leverage in that they have the threat of nuclear weapons backing them.  we have to take them seriously, because they dont follow our system of MAD.  Why do you think the UN has gone on a crusade against any countries besides the US and Russia that have or try to develop weapons? 

India and Pakistan were harshly sanctioned and reprimanded for developing nukes.  Why do we want them to stop having nukes?  Why should we sanction them and not North Korea?

#1135 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-31 10:47:42

nuclear weapons to make itself a world power.

oil is needed for almost every major industry.  why would they not need oil?

#1137 Re: Not So Free Chat » President Bush - about bush » 2002-12-31 10:01:05

Maybe Bush is onto something:

http://www.debka.com/article_print.php?aid=232]Article about Hezbellah use of Iraqi missles

http://www.debka.com/article_print.php?aid=214]Article about Al Qaeda plans for terror attack against Israel

After reading the Iraqi missle article, I'm a little more in support of a war.  Maybe the government actually does know something we dont.

#1138 Re: Not So Free Chat » President Bush - about bush » 2002-12-31 08:02:18

well, considering that the palestinian state that was sanctioned by the UN exists, and is named Jordan, i think the Palestinians might be violating a resolution of their own.

Many people choose to ignore the fact that Jordan is the UN-created Islamic state-but its the fact.

#1139 Re: Single Stage To Orbit » SSTO - concepts » 2002-12-30 16:27:36

yeah, but VTOL wouldnt make use of our existing facilities as well as a horizontal SSTO.  nuclear powered thrusters would allow much greater payload, which would make landing gear trivial-and this is also within our reach.  nuclear powered vehicles can be made to be at least as safe as conventional vehicles.

#1140 Re: Single Stage To Orbit » SSTO - concepts » 2002-12-30 16:16:11

anybody want to guess on what the configuration/design of the first SSTO will be?  ive seen a bunch, from vertical to horizontal takeoff, nuclear powered, in-air fueled, scramjet, etc. 

My personal inclination is a nuclear powered spaceplane that takes off and lands horizontally, so it could replace the airplane and Space Shuttle industry in one sweep, and use existing infrastructure.  Besides, they look the nicest  big_smile

#1141 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-30 16:07:53

if it werent for the chinese, we would have won the Korean War. 

Second, would a nuclear reactor stand up to continued bombing from normal airplanes?  sure, it could stand up to a certain amount of beating, but i dont think it could stand up to sustained, deliberate bombing for very long. 

third, what 2 wars?  yes, they used them in ww2.  when else?  and the use of them in ww2 probably saved western europe from a soviet invasion post-ww2.  it also showed the world the capability of nukes, and led to MAD, instead of wanton nuclear use.

#1142 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-30 13:52:16

or we could strategically take out their nuclear plants.

#1143 Re: Not So Free Chat » North Korea - Well, someone had to start. . . » 2002-12-30 12:36:26

Bill, if someone breaks a treaty to build nukes, what do you do?  Say, oh its ok, let me pay you to do what you said you would do, and hope they never do it again?  Thats ridiculous. 

We should throw out every treaty we ever signed.  Legality is of no consequence, a treaty is only valid as long as the country "likes" the terms.

#1144 Re: Planetary transportation » Crawlers - Segmented multilegged rovers » 2002-12-30 11:58:23

that would be great.  for construction 'bots, i think treaded robots would do the job best.  they are more sturdy, and they would have less parts to maintain.  in construction work, that many legs would create a problem when the weight becomes greater.

#1145 Re: Not So Free Chat » President Bush - about bush » 2002-12-30 11:55:59

el scorcho, if an iraqi bomber flies over your house, are you going to look at it and wave? 

iraq is cooperating with the UN.  Bush is trying to find any way to show that hes not.  one country says "We have and are building nukes" and Bush says "Well, we'll see what we can work out"  the other says, "We have none, go ahead and check" and we want to invade.  Wheres the logic?

#1146 Re: Martian Politics and Economy » A Few Insulting Remarks About NovaMarsollia - The latest fruitcake around here » 2002-12-29 17:52:43

nature has always favored those with the means to survive and acquire.  i dont think mars should be used as a utility to be sold, but i think that those who are enterprising enough to get there first should be the ones to get the best estate.  if europe gets there first, so be it. 

im not saying this as an american, im saying it as a living being.  the ISS is a perfect example of what happens when you try to help the less forunate countries-we're stuck with almost complete cost for an internationally shared benefit.  it probably hurt our chances of space development more than it helped--that money has to be recovered over time.

#1147 Re: Planetary transportation » Air Transportation on Mars - Gravity's affect on Air travel on Mars » 2002-12-29 16:40:34

it means you would have to have the jets propel themselves, rather than be carried by air, like rockets do.

#1148 Re: Martian Politics and Economy » Mars as an alternative to War. - Can space exploration replace War? » 2002-12-29 12:24:02

i think the concept of a stock company for mars would be a good idea for space exploration.  the society, or any other organization, could create a mars firm, separate from the organization for business reasons, that provided funding for the exploration of the stars.  if enough people were willing to buy the stock, huge amounts of funding could be acquired, and even spread to many space development companies.

#1149 Re: Interplanetary transportation » Nuclear Propulsion - The best way for space travel » 2002-12-29 07:53:22

thanks for the link austin.  so how efficient is this process?  what percentage of heat is wasted, just a ballpark estimate?

#1150 Re: Not So Free Chat » President Bush - about bush » 2002-12-29 07:50:46

international community contribution of light water reactors

hmmm, i see.  so its only the US that could provide them with reactors.  the agreement says explicitly international.  But of course, blame the Evil US.
