Lunacy from Brussels

My personal natural dose is scheduled to be 23 rem total, and it probably won't kill me.

If you look at the chart closely you can see that larger ships need less extra sheiding, at the size of Rhysy's animation the structural shieding of the ship would lead to a engine does lower than 50 rem. Additionally a 4,000 ton design allows margin to redesign the GA radiation shelter for much lower trip doses.

Actually, it was ~100 rems over 3-7 years (i.e. a rate comparable to what I said).

And yes, I think that the first few trips to Mars will be dangerous. By the time it's routine, the shielding problem should be under control. We will be a spce faring civilization by then.

How do you plan to just 'move the water' you rabid idiotic fathead ?

You think it's practical to move it from a moon ? You're a real piece of class stupidity.

SOLAR FLARE !

And that's supposed to be safe ?

Exposure (rem) Health Effect Time to Onset

50 nausea hours

70 vomiting

90 diarrhea

So you'll have one *very* sick crew !

Bloody brilliant !

Graham

I know.

No damn good at the poles though.

Does your tap at home run iceberg water ?

Graham

Oh ! you mean it won't kill them outright ?

Very nice.

GO BOIL YOUR STUPID HEAD !

Graham

Buy a Saab.

No 'wires' to replace.

Graham

If you reckon a 100 rem dose of radiation is acceptable then you're even more berserk than I first thought!

Hello Ken,

Not around here. Most are belching some oil because of worn piston rings (major job). Valves are clattering because the stems are worn, a lil' oil leaks out the transmission side bearing, you can rock the distributor shaft to which the points are linked back and forth by hand. And oh, there is also some oil leaking into that assembly ;-)

Some of these are just very poor designs. Others have suffered excessive wear because the owners thought that changing the oil after 15,000 miles when it is pitch black would be enough. I have seen one guy whose engine ran hot. Old Catalina or something like that. There was plenty of water in the radiator and the pump belt was kinda ok, so that couldn't be it. Pulled the dip stick and whoops, the oil was nearly gone...

I wouldn't mind 90 minutes if it is safe and away from traffic. But out here there are too many crosses next to the road for people who have tried.

I am not so sure. In Europe almost any city or suburb is completely mixed use. Real estate agents make a similar sales volume. Except that people over there don't sell that often and commissions are about half (used to be about 3.4% in Germany versus 6% in the US).

I bet if they'd try to market a residential area where jobs are within biking distance and shops are less than a block of walking people would literally rip it out of their hands.

Hello Graham,

Nice car, nothing flopping around in the engine compartment. In California they call them "the engineer's cars".

But when you do need a spare part brace yourself. Once I was helping out a guy restore the main brake cylinder. It was in Scotland and since his car was out of commission while he took out the cylinder I drove to the store. They wanted a whopping 90 pounds for two O-rings, one cup and some simple metal clamps. And that was back in the 80's. That kind of made me decide not to buy one.

Toyota and Mitsubishi aren't bad either. Nice and tidy engines, not much loose stuff at all.

Regards, Joerg

See the context !

" allowed dose is 5 rem/yr " - indeed and that should be regarded as an upper limit.

Repeated exposure to radiation is not considered healthy.

Graham

To visit a dead rock ?

I 'm sure the sense of that is clear to all.

Graham

Actually the NRX series of nuclear thermal rocket engines, done in the

Actually, the previous poster was talking about ~ 100 rems.

Additional exposure from space flight is another source indeed.

I see you consider a Mars mission dangerous in this respect. Kinda where I was coming from.

Graham

There are still cars around with points ?????? !!!!!!!!

Goodness.

Mine doesn't even have a distributor.

Graham

I wouldn't be caught dead buying a Saab or any other GM crap, particularly now. There isn't a European car I'd buy on a bet because they cost too much to keep on the road. Then there's the GM connection.

Graham,

Notice that he didn't say just how far in the future that will be.

But maybe you're one of those people who thinks technological advancement will end in the near future.

Paul

Perhaps you mean "as long as someone is paying them to be mad at the world". I say, let 'em freeze in the dark.

"Irrigate Mars?" Sheesh!

Um, perhaps there is a reason there is no longer water on Mars? ...like the escape velocity is too low to keep it there? mars might be interesting if it were about 4x bigger, but then we might have competition.
