    If that antenna's for bouncing energy from an ordinary (well, high-power but otherwise unremarkable) microwave horn, you could build it out of hardware-store bird mesh tensioned with fencing wire. I kid you not, it's quite different from building Parkes-in-space: you need naff-all structure for something like that.

    You could even omit the fencing wire and just spin the reflector. It's not as if there's anything in space to slow it down. Or rust it.

    It would be a money sink that would never pay back its construction costs

    Complete bollocks. Specficially, if it cost $20G to build (they say $10G), it need only make $2G/a to handily beat bank loans and stuff as a payback means. So double the $100/kg lift costs to $200/kg, big deal in the face of the $10,000-$30,000/kg it is now. $2G / $100/kg extra profit == 20Mt/a, 55,000t/day, 2300t/hr, a 400t load every 10 minutes.

    Need to halve that load? Triple the price instead of doubling it. Or use the elevator to build more, and amortise the costs between them.

    It would be the worst sort of governmental monopoly

    And we don't have one now? Go ahead, build your own Saturn V or Energia-Groza, be my guest.

    Once they have half a dozen of these up, owned by 3 or 4 countries or consortia (I'd guess USA, EU, China, Russia, India, Brasil), that starts to break down anyway. If Australia wanted to build the first one, that would cost us $10,000 a head. If it built the 8th one, maybe $500 a head and every Australian gets their first 2kg hauled to space for free. If the people living in Perth pooled their gree kilograms, we could loft a 3000 tonne satellite.

    It would be The Definitive Terrorist Target

    Ever tried to hit something a meter wide from 10 km away? With defenses on the elevator shooting back at you and at your shells?

    Clearing a corridor 10km wide around this would be no problem, and keeping it clear with SDI technology (near the ground, a perfectly ordinary Vulcan radar-guided cannon would do the job) relatively simple. Can you outfly a laser? Could your aircraft or missile survive several hundred unexpected megawatts of microwaves tuned to some vital dimension? How about a smart remote-targeted crowbar dropping in on you from LEO at mach 20?

    It would be a murphys-law magnet

    Any concievable replacement would be worse.

    And that's even before an orbiting piece of space junk slams into it.

    It would have to be a clever piece of space-junk, smaller than a peanut and yet more destructive than a nuke. You haven't had a look at the design, have you?

    If they were kind enough to put the elevator up on the Equator (not necessary, but it helps), it (or more specifically the defenses on it) would actually make a pretty good street-sweeper for the space industry.

    And it would be a catastrophe waiting to happen, when (not if) it snaps and rains megatons of carbon cable down upon the ground below.

    That statement just betrayed your complete ignorance of how the elevator would work.

    Of the 100,000km length, less than 100km would be in atmosphere. Take what is presumably the worst case: the cable snaps about 50km up. 50km of cable fall to earth, the top 30km or so burning up on re-entry, the balance stays in orbit. That's right, losing 0.05% of the cable makes very little difference to its orbit. Soon the lost 50km is replaced by shipping it out along another cable and unreeling it off the next segment above the damaged one.

    But what about the bottom 20km? Even if it were heavy (did you read the line saying `paper-thin?'), it would fall into the ocean. Even if they anchored it at, say, Kununurra (in the far north of Western Australia) and it were heavy, you'd still only lose a stripe of desert a few m wide and 20km long. Big deal.

    But I wasn't talking about miles.

    Neither was I. My thinko. Read it as `hours'.

    It takes 9 hours to cross the Atlantic [...]. If it hauls 466 people each time (I think that's about right for a Jumbo) then one round trip is the same number of passenger hours as the average passenger hours between shuttle crashes.

    The two cases are still not equilavent because one jumbo crash loses 466/7 (==66) times as many people as one Shuttle crash.

    OK, we've had our fun, time for some facts. The fatality rates I could find were: trains are roughly 4 per 100M hrs, coach/bus 1, private cars 171, motorbikes 382, pushbikes 57, pedestrian 22, air 3. For most modes of travel the casualty (permanent damage) to death ratio was roughly 10:1.

    So... motorbikes are roughly 2.5 times as dangerous to their owners as cars!

    On the same scale, using the 8400 hour figure to save dispute, the Shuttle has 12000 fatalities and a 1:1 ratio. Forty times as dangerous as a motorbike, and four times as dangerous as smoking.

    a big, looming space elevator wouldn't be a target for terrorists, would it?

    Yes, but much harder than a building to hit and destroy, and fairly easy to mount defense ordinance on.

    Also likely to have space-based lasers mounted at top end which could be brought on line in seconds, plus the ground-based propulsion lasers could be borrowed, ganged and focussed for the very brief occasion (a safer option IMESHO).

    Near ground level, something like a bazooka shell would be easy to isolate automatically due to its trajectory, and a perfectly ordinary Vulcan Phalanx (50x20mm shells/second) would take care of those as it does for ships. Even if you completely flubbed that, and assuming that you could build enough brains into a bazooka shell to hit a terribly skinny target, and scored a direct hit on a ribbon, you won't necessarily have achieved anything. Firstly, each ribbon would be a wonderful shock-absorber, secondly, there would be many ribbons, so even if you got two or three of them, the results are unlikely to be catastrophic, thirdly, the elevator is in orbit, so severing it low down wouldn't achieve much (in fact, the plans include winding it up a few miles if a really nasty storm arrives).

    You really should go read the site, they've obviously thought of this stuff.

    Something that large will get hit by meteors and junk regularly, so facilities for repair would be routine. The ribbons are arranged in a semicircle (there's not really any such thing as an `edge on' hit) so anything hitting it would have to be seriously sizeable to cut more than one strand, in which case the lasers would get it. In fact, said lasers would become important and useful for cleaning up LEO.

    Every shuttle down is 7 deaths, every Jumbo down is roughly 400 deaths (depends on model), some of the bigger airbuses will be 800 or more deaths, perhaps plus innocent bystanders (very unlikely that a falling Shuttle part would kill anyone), assuming that very few people survive hitting a hillside at over 500km/h, the typical scenario.

    ...and here is a straightforward but far from easy way to go up. With dollar figures and production schedules.

    Perhaps they should have priced it in terms of Shuttle missions. The shuttle has launched over 100 times, at a typical cost of about $500M per launch equals roughly $50G, so their elevator would be priced at 80 shuttle missions or under 4/5 of the money spent so far running the Shuttles.

    Speaking of which: in terms of fatalities per passenger mile, they're much safer than jetliners, orders of magnitude better than your car. OTOH, you car doesn't cost billions of dollars to replace if you write it off. OT3H, I'd be really happy if I got that many miles out of any car, ever. (-:

    My apologies to you. I am Australian, and I think I know something about how you feel.

    Some years ago, a computer shop I worked for was broken into, a few weeks after I stopped living on the premises. They used, would you believe, a circular saw on the lock of the (Al and glass) front door. A simple screwdriver or pry-bar would have forced any of the other windows or doors in the place almost silently, including ones opening on the side driveway, coneniently shielded from most prying eyes by a tall, opaque "super six" fence at the time. They stole a lot of old, non-moving stock, and a very few new computers (next shipment due soon).

    Anyway, the CIB (sort-of the local FBI equivalent) came knocking at the door of the house I was sharing, scared the daylights out of the girl I was sharing it with, forced their way in and searched my room. Lo and behold, lots of boxes marked Apple (I'd used them to stack my gear in for the move), so they got all excited, opened and upended everything looking for the missing computers. Not having any luck, they shot through.

    Some hours later, I came home to find my room a complete shambles. As I started tidying everything away again, the CIB dudes returned, knocked, asked me if I knew anything about it, and while I was answering (no) basically gathered around and forced me out to their car. They sped (illegal in Oz unless car has lights, siren and proximate cause) back to their office, locked me up in an interview room, and left me for an hour.

    They came back in en masse, one carrying a wire coathanger, and started asking me questions while they did stuff like whack the coathanger down hard on a book, then tap me with it. They started shoving me around, and threatened to do stuff like wrap me in a blanket (showed me the blanket) and then kick me at random spots through a 'phone book (so it would hurt like hell but leave no bruises).

    Instead of having the desired effect (cowing me), it made me really, really angry, and it became obvious to the leader (the only guy with any brains) that (1) I wasn't guilty; and (2) if they didn't stop, I was going to start hitting people really hard and bugger the consequences. So he called it quits and they drove me home. This made the rest of the thugs very angry.

    The only feature of your story that's missing from mine is that I wasn't a long way from home.

    The airport security at Perth is a joke. I strongly recommend that you don't, but if you wanted to blow up the Domestic terminal, you would just drive an old Tojo loaded with explosives, carefully but quickly, through the rent-a-car area on the north end of the terminal, through a pair of ordinary glass doors there, and you'd be right in the middle of the check-in queues. Blow your truck up there and you're assured of at least 400 deaths if there's a few flights due out. Same story at International, but it's the arrivals (East) end you'd be hitting - or you could make a smart left with same Tojo through the glass at the front. Even if those weaknesses were fixed, fly a light 'plane from Jandakot in low over the suburbs, pick a window, and fly through it - or play chicken with an inbound or outbound jetliner. There is nothing security could do about it.
