Good day all. I am a London based designer and innovator by trade who has put up his working boots for good and wants to get back to building awesome things. I have a regrettable history, having built a small armada of electrostatics, transmission lines, open baffles, isobariks and hooked up the amplifiers to drive them. My kids grew up expecting loud bangs and the smell of lightening in the room.
Now I have the time I want to get experimental, explore the edges and see what can be done. As a client once told me of one of my more lateral designs "You're really Martian."

hehe, when I first started out on Internet forums I was super paranoid about my identity so wanted to use a pseudonym. I thought what better than the all pervasive wintermute! I really enjoyed Neuromancer when I first read it in the late 80's, it obviously made an impression ;)

I saw "The Martian" on Wednesday. Really cheap "senior's" showing @ £3.29 including a coffee and pack of biscuits.

A nice bit of fiction and well portrayed.

But my question is to do with Martian physics:
How do rubber tyres work on Mars?

Great movie and very accurate. The tyres thing is an excellent question. My guess is they are liquid filled as the surface air pressure is very low- .087 psi. The other problem is the effect of ultra-violet radiation on rubber so I am guessing its some form of synthetic???

Personally I use my pseudopods.

Nanu nanu

Neuromancer set my unfulfilled SCI-FI writing career back three decades!
Bill went to the movies, saw Blade Runner and nearly gave up- really glad he didn't

I thought my 'BurntCoil" identify was really cool yesterday, but I am informed by my son it's really naff. Still, if it embarreses him that's a two for one in my book.

I'm thinking about the liquid nitrogen experiment.
Dip a rubber tyre in liguid nitrogen !
Will the tyre disintegrate when one runs over a pebble/rock/boulder?

What are the overnight temperatures on Mars?
What is the temperature on the shaded side of the tyre when there is almost no atmosphere to warm it up?
 
I live on the equator so midday its a balmy 20C so yu could visit and not freeze, but you'll need a really good camper van as it dips to -120c at night, which I imagine is brisk even for a Scot.

You'll need some antifreeze in the tyres to keep the water from freezing, but water is your best bet.

The Martian: very good movie, but here what I saw that was suspect.

The gravity was much too strong, you can't really run, more of skipping or hopping if I remember my other sci-fi /PBS specials correctly.

He makes a comment about the horizon being far away. The horizon on Mars is much closer than the earth's since it's a smaller planet.

I think but really not sure, that the dust storms do have very quick winds, but since the atmosphere is so thin, the pressure/force is much lower than shown. Can anyone comment on this? I could be really off base

But I did really like it, I'll have to read the book.

Mars is small, I think I am right is saying it's the same surface area as North America, so I agree that the horizon would look closer. It looks very close on the moon.

Gravity was always going to be a problem for them so they had to gloss over it. I thought they did zero G really well on the ship though.

The biggest problem for me was the storm ripping up the tent, until I remembered that the tent habitat was pressurised so all it needed was a small rip and the over-resume would do the rest. At least that's how I rationalised it to myself.

Obviously in real life my exoskeleton deals with the winds comfortably, all I have to do is withdraw my tentacles to prevent frost bite.

Now I gotta start posting about projects or the mods will be reaching for the bug spray.
