Tenfold electric vehicles on 2030 roads could be a shock to the system

Re: No shit

It is not just rows of Victorian houses lining streets not built for cars.

There are roads - many, many of them - lined with "modern" houses from the 1970's and later that have cars parked all along them on both sides

to such an extent that they are essentially single-file lanes for much of their lengths.

True, some 21st Century housing estates have short driveways and parking slots for a car but those often have more than one car per tiny house.

The problem is not petrol cars, it is *too* *many* cars.

Ask anyone who commutes during "rush" hour, even those car-free folk travelling by bus.

Re: "chronic or long-term effects of such dust exposure could be a problem for future missions."

I have never understood that argument.

Surely we should be doing both. And building cities from the mile-wide Asteroids, using Phobos (not the other one, it's pretty much useless),

colonising Mercury and Venus (yerp, that one could be done though it would not be easy) and building City-Farms in Earth's high orbits.

All at once.

And we should have started in the 1970's.

There was a time when we could have afforded it all, had the Dream Of Stars to drive it all, could have taken the Galaxy.

It is possible that the Dream is dead and we can not do any of these things, that we lack the treasure, the will and the ambition. That we are trapped.

But surely we should be trying?

Re: Why does anybody want to go there?

Once terrified, Luna would not need dust busters. They dust would settle into clays and muds just as it does on a nearby, wetter planet.

As it mostly does there. Usually. With some local, temporary exceptions.

Unlike the local Big Sister World, though, there would not be any tectonics to cycle the muds from the bottom of the Lunar Ocean so any citizens

would need to build piping and pumps and ejectors at the top of the higher hills. [See the "Ringworld" series for details.]

Okay, it's a bit expensive on the water front, in that it would mean actualy using some, but a 30 second rinse of the suits shouldn't use

Star Fomalhaut has dusty little secret – two more debris belts and a potential planetary party

If a Fomahautian planet gets to be solid, with a reasonable gravity and atmospher and it orbits far enough from the star, it could be used

for several tens of millions of years by a wandering, technological culture before the star cooks it.

Falling rocks and icy blobs could be equally useful, if not more so, assuming Fomalhaut keeps some around.

The blackness is the blacked-out star.

Stars are *very* bright, even in infra-red and that one would overwhelm the light from the dust clouds. To see how bright a star can be, see Sol

Re: Something else is wrong here..

"What in the name of the Deity is an "honoree"?"

It's something like an "honouree" only shorter and more USofAn.

It's someone being honoured for something, or something taking the honour of being something. For example, a dark region of the cosmos being

"honoured" for being the biggest collapsed object so far found.

Though I would not call that an honour, more like recognition of it's place on a list, which is just one random property of an object.

It's like honouring (or "honoring" if you are USofAn) a girl for being the one with the reddest hair. Only less significant and probably temporary.

Re: Pretty decor

"Nobody wants to have to rip away fake potted plants and wall panels to get to a leak."

That is just engineering and designing. Make the potted plant tubs and the thin, pretilly dyed walls behind them easily moved and you can access everything

easily, rapidly and safely. Make them easily moveable and you could even change the decor every so often. This should be one of the *first* things thought of

when building stuff.

And every single room in every suite whether for tourist or crew could have their own "window", a low power screen showing the Cosmos from the non-rotating

hub. Those would double as large comms-computer-wallpaper screens.

Why does everyone *always* insist on making things ugly, expensive and bloody difficult? Cheap and pretty works in Hotels down here. We are currently

hiding hundreds of millions of kilometres of piping in our buildings and we've been doing it for over two millennia. Doing it on warships and orbiting habitats

isn't exactly rocket science.

And the issue of bugs building up behind the panels and around the piping? Well, many supermarkets down here sell shopping bags with anti-microbial

inner linings. I'm sure the bright ladies and gentlemen at J.P.L. could use that concept. Or something better.

Re: 2001

"Trump would most likely just demand they add more floors to an earth-based tower until it reached space :-)"

Such a thing could possibly be done on Ceres and anything smaller. Some falling rocks even have littly, baby rocks already in orbit around

them that could be used for construction materials or asteroidal-stationary mid-points.

Maybe Pluto, too, though a Pluto-Charon Bridge might be more fun and easier. For a Plutonian Orbital Tower one would probably need to spin-up

the planet so the "centrifugal force" could be high enough to keep it upright. Looking at it another way, we'd need to create a viable stationary orbit

for the Plutono-stationary centre-of-gravity of the tower to live in. Spinning-up a planet is simple engineering and highly expensive economics. It

would do things to the P-C barycentre. Maybe.

Eros could have a launch tower poking out. Maybe two, for symmetry.

An orbital Tower on Venus would have to be large enough to reach half-way to Mercury. She doesn't rotate very very rapidly so cythero-stationary orbits

are extremely wide. Spinning up Venus would be a tiny bit beyond Man's present economic base. Though, if done, it would help with Greening the place.

Note: I said "easier" about the Bridge, not "easy". :)

I wonder whether, when Mr. T. wins next year, we could interest him in building things like these? As Vanity projects, they would quite literally be out of

this world. Why have a face carved into one tiny, obscure hilltop when one could use entire *worlds*?

Re: 2001

"he meals for the current ISS crew costs thousands per portion with most of that just in transportation costs."

Which is one of the main reasons why we should have been building City-Farms in high orbit fifty years ago.

Growing foods in orbit, even fake "beefburgers" in vats, would, once the farms and support cities were up there, be literally dirt cheap. Sending them around the

various sciencey, techie and engineering stations would be simple orbital mechanics and timing. Fetching waste, such as sewage, to help defray some of

the burden of replacements of volatiles is simply returning the Pizza-delivery vans full instead of empty.

We should have been sending up scores of Skylabs and MIR's and using the shells of re-supply modules as extra mass for add-ons so that by now we'd have

the infrastructures to create a vast Civilisation off-world. We should be using the re-supply modules to add to the ISS right now.

Of course, we should also have the Hubble in high orbit, with the infrastructure up there to add to and maintain it, as well as Hubble-27 and friends but that, too

is a non-starter.

It's a shame that start to the grabbing of the Human Galaxy will never happen, is no longer possible.

Re: All alone in space

"Weird to think it'll be another 300 years before it gets to the Oort cloud."

And millennia before she passes out of it. The cometary zone is *huge*. It extends half-way to Proxima ...

Which leads to interesting ideas.

Should Proxima and all her little freinds, such as Wolf 359, have extended cometary zones it may be possible for City-Farms to use the ambient resources

to sustain themselves while drifting from one to another. Interstellar travel, the slowest way. Indeed, a loosely coherent "civilisation" of City-Farms may be

the easiest way to colonise the Galaxies.

Not that it will ever happen but it's nice to think about.
