Here is what i have so far.

http://www.evforum.net/forums/attachmen … 1193175477

it will be all electric, i see no reason to use any other means of power that is so limited on a distant planet...

hydrogen fuel cells are completely stupid if you research them at all, and see how limited they are. they only produce about 2/3's of the power of gasoline, require lots of power to make, and are limited in range.

in an electric vehicle, there are many methods of powering and running it.

in my vehicle i have a custom made electric motor in there (those cylindars) and the diameter for the main part of the vehicle is 48" so it is a decent ammount of room for 2 people. the wheels are 36" in diameter.

top speed is roughly 60-70mph, range is unlimited (again not going into detail yet), can cary 2 people under a standard situation, and up to 4 under any type of emergency situation. there will be lots of storage compartments on the sides as well. (those bars sticking out the sides will support the "saddle bags"

What about a vehicle based on the same principle?

that might be a bit better, but it would be very unstable given some of mars's storms and the terrain. look at the rover pics and you will see MANY rocks all over the place on the planets surface.

i'd say your best bet is to have a very basic plow on the front of a simple vehicle.

or even have rovers go arround and clear paths of rocks before going somewhere out there.

#53 Re: Planetary transportation » Get a Spring in Your Step » 2007-10-29 08:23:03

that would be great for quick little jaunts, but for the majority of travel on mars it would be almost a bad idea... your thinking about a majority of scientists that will be mostlikely not all that corridanated jumpping possibly up to about 5-10' off the ground. that could lead to some very bad injuries.

I'd suggest a simple vehicle of sorts over something like that.

#54 Re: Planetary transportation » Bikes on Mars? - Don't laugh! » 2007-10-29 08:02:48

I REALLY like the idea of using bikes on the surface especially since you can go pretty long ranges with the same energy as a it would take here on earth with a short trip all because there is less gravity there.

there are a few things though that i wouldn't agree with using them on the surface though, one would be that you would need a BEEFY bilke to hold both you and all of your equpitment since i'm assuming you would be using the bike not just for a "ride"

more things i would also wory about is the misc rocks all over the surface. riding will be slow since you have to dodge them constantly.

#55 Re: Planetary transportation » Who would be intrested? -Design a set of vehicles for mars- » 2007-10-29 06:18:31

yea they are really cramped, that is a good design for use out there, but it would be better to give it a bit more clearance, and you have to think about the tires since the tires will be a big issue. i've actually been working on a design that would work out there but i'm going to wait to announce any more info on it until i have more work done on it, thus far i have the motors set in it, the frame (all tube frame) and the basic locations of the wheels and the seating area. otherwise i still need to insert all the basic driving components... im' actually going to build it too so i'm designing it pretty accurately.

Now is the frame going to be steel or aluminum or titanium? With the frame structure don't forget about deciding if the frame  will be welded or bolted together.

for the version i'm making, it will be made of composits since i have to pay attention to weight. but for that version on mars, i'm not sure yet, i'd immagine either aluminum or steel, no reason for it to be made out of titanium.

as far as a vehicle that would "pave" the surface.... honestly the best way to take care of something like that would be to send numerous simple robots with "plow" capabilities. and in all honesty... on mars it isnt exactly a smart thing to stay on the surface, but to actually be underground since those storms are both VERY strong, and last a LONG time. it would only make sense to be able to store everything under ground so perhaps have some vehicles shipped out there pervious to anyone getting out there to dig a hole or at least clean up a previous one for staying in.

#56 Re: Planetary transportation » Who would be intrested? -Design a set of vehicles for mars- » 2007-10-28 16:50:45

Good that more than paper is being created with the proces of building the design. I have lots of questions about your design Dragoneye, with respect to how many crew members will it carry, is it presurized, method of powering as well as fuel used, maximum driving distance plus speed, intended life support if any for crew in case of spacesuit damage.....

as far as how many crew members, it will hold 2 in a standard situation but can hold as many as 4 in a case of emergency. yes it is pressureized. as far as the method of powering/fuel being used, that is one of the parts of the vehicle that i wont reveal till later because its still being worked on. as far as driving distance it is capable of unlimited distance, and as far as speed figure a top speed of arround 70-80mph.

#58 Re: Planetary transportation » Martian Whirlwinds - A Threat..Possibly » 2005-09-02 12:01:08

hummm i like what cindy posted... that article mentioning that there could be multiple in one day.... well if we found a way to harness the power from the storm... we could lay off using specific sources of power like some solar and what not. we could build machines that take in the static that it produces and stores it....

#59 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-09-01 07:33:26

Telescopes built that can see earth like planets at near stars, giant drink coke signs visible from earth, precious metal mining with easy to earth transport, shuttle services, magnetic rail guns, transport, hotels, construction companies, moon based satellite repeaters stations, etc etc.

A big company with vision could own it all now, and be the first to do the same at Mars.

exactly....

you need money to make money...

I am more than willing to help this effort in full force, but like i just said, I dont have the money for it.

#60 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-31 11:39:36

it would be a gold rush, heck, just think of the possibilities.... people would be thinking up of new ways to get to and from space easier, cheaper, faster. research labritories set up on the moon, possibily hospitals for rich cancer patients that want to live out their days in a super clean environment, and so on... there are lots of things to do up there as well as mine the moon....

#61 Re: Human missions » Space Elevator, Ho! » 2005-08-25 10:06:23

And I've steered him toward that article today because, when he brought up the subject of Space Elevators at school recently, his teacher made a mockery of the concept in front of the whole class.

I don't understand teachers like that.  :!:   :?

*Geez, how sad.  It proves the stereotype of uneducated people as being little-minded is false. 

It's one thing to disagree, but to ridicule a concept in a manner which humiliates a child before his or her peers?  Unfortunately I've known a couple of teachers like that.  Educated fools.

Back on topic. 

--Cindy

no that raises a good point, all it means is that people dont like creativity... space travel in the present is all about creativity... "how can we get arround this", or "how can we do that?"

to get people more intrested we need to get things on a level of people wanting space to hurry up so they can beniffit from it.

#62 Re: Interplanetary transportation » Magnetic Launching Points » 2005-08-24 10:39:25

what do you mean by space elevator though? just a huge satelite in space with long cables reaching down to haul something up into space? I was thinking something more along the lines of just making new technology so that we can bypass the bypassing ways of it all....

#63 Re: Planetary transportation » Airplanes on Mars » 2005-08-24 08:36:24

Personally the best idea idealy would be a blimp....

basicly all it would be is a box with a battery, lots of monitoring equiptment, fan, and a huge bag with Hydgrogen.

heck if you dropped it off just like they did with the rover, they could make the surface conducting so the blimp could land back in its spot, and recgarge with some of the solar panals that are out there on the initial unit of the ground unit.

heck, if you wanted to see something far off, you could always have a rocket that launches off of it and just fire it in that direction. have the rocket relay the couple thousand pics it took, and that replaces your need for a one time use plane with something a bit more permanent.

#64 Re: Interplanetary transportation » Magnetic Launching Points » 2005-08-24 08:16:40

The problem seems to be launching from earth, not the magnetic rail system.

On the moon such a system will achieve escape velocity easily in a km or 2km track with only electrical power.
Maybe the solution is to launch and build everything for space on the moon, even the track and launch vehicle.

Just my thought though smile
Earth is just to fat.

I agree for things in space, but we really need something that can easily bring stuff into and out of space with no problems. even if it means distorting gravitational fields...

#65 Re: Human missions » Space Elevator, Ho! » 2005-08-22 09:07:51

space elevator would be cool, but we honestly need to work with nano technology alot more and start getting nano machines out there helping out with building processes and what not...  just immagine making diamond encased reactor cores out of a pile of coal, ropes that are highly flexible, lite, and strong.

heck you can use nano machines in bodies too. clean up any problems with the heart clogging, bad cells, fix more specific problems in the body and what not.. lots you can do.

#66 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-22 08:17:55

we could always do weighted clothing... so it feels like your moving arround on earth...

then when you go to do stuff on the moon, like mine or what ever, take it off and you will be like 6x stronger than normal being able to move stuff with alot less gravity pulling it down...

#67 Re: Planetary transportation » Who would be intrested? -Design a set of vehicles for mars- » 2005-08-22 07:46:37

When you say air born I assume we it doesn't go into space and since it has two people and cargo on board, that would eliminate an air plane type craft because the Martian Atmosphere is too thin. So this craft would have to be either a blimp type or a rocket type craft. That the only type that I know that could operate with those guidelines.

Larry,

yes thats correct, and unless you can figure out alternative means to making it stay aloft.

Personally im going with a decently high speed blimp... it just really makes sence for fitment, reliability, and everything...

as far as the driven vehicle im imagining something close to resemble a SUV/Plow....

if you look at the martian terrain it has a wide spread of rocks all over the surface.... you need something to clear that terrain not to mention you will need to clear the rocks so that you can make paths for other such vehicles and what not for higher speed ground travel.

#68 Re: Human missions » Space Advocacy Fragmentation » 2005-08-19 14:05:44

I'm all for going to mars, but honestly i think its impractical to go at the current time, we just dont have the money, technology, and intrest in getting to that point from the rest of the world, or even just the rest of the US as it is...

we need to get a break through with technology to get us there in a record time, or invent something that will want people to be like "oh hey look at that, we can start traveling to other planets in 1/2 the time, i dont mind investing a few bucks to get something like this going."

its something thats outstanding that people will want to put intrest into... no one wants to invest money in something thats the same stuff we have been doing for years, but just in a new place...

we need to get others excited about things. once we do that, then the money comes, and along with money comes more research, and intelegent decision making.

#69 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-19 13:57:44

Hmm...Centrifugal workouts. I wonder if that will catch on earth. The spin Gym.  lol.

only a few problems with it though... getting your orientation, that will be hard to take care of, and honestly some people just wont be able to do it...

#70 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-19 09:07:35

well then that would be even better on the moon, for sleeping and what not.. just put them in the revolving machine to keep pressure on them and kep it like earth. when you need to go out and do work, then turn off the machine and get out, and you will be at 1/6th again... its all a matter of design to take care of things... once a day even would be better...

its like being on a trampoline all day and getting off for a while, and you can feel gravity really kick in...

#71 Re: Human missions » Space Elevator, Ho! » 2005-08-19 08:50:10

this stuff would be great for so many uses... imagine a 5 layer body molded peice... that stuff would protect you so well... or for skin on a plane to keep weight down. Wiring for vehicles since its conductive light, and thin. woven into a solar sail. and so on....

I just wonder how much this stuff will cost.... i would love to get a roll to play with it though. even if it costs $50 for a roll, i would be willing to get some just to experiment....

#72 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-19 07:18:39

I'm not talking about genetic modification mind you, thats a whole different can of worms, but rather a drug that either prevents the body from deciding that you have too much bone/muscle mass, or one that orders your body to make more without gravity or excercise.

Of course it would be a billion-dollar industry on Earth if you could get it to work... no more heavy excercise to lose weight or bulk up, just a pill or a patch, and ostioperosis will be a thing of the past. Want to run a marathon but don't want to spare the time for intensive training? No problem, just wear this patch for four months prior...

there are other ways of going about this... i dont know about you but have you seen the drugs that are out lately? like lets take one thats a decently well known drug, like pain killers... well there are various kinds. Viox is one in specific, well that one does a good job at what its supposed to do, BUT it has side affects... like increasing the chance of heart attack... so basicly it renders it no good. im not saying it doesn't get the job done, but still it has side affects...

sadly enough you will go through the same thing with medications.... SO in order to battle bone/muscle loss i would suggest something like electrotheropy (just like on the movie the matrix where he gets his muscles back into shape) or there are other ways too, but that seems to be the safest way...

as far as Bone Loss, the body addapts to its environment, so if you have less pressure on the bone structure then obviously it will loose the need to be so strong in specific areas. but if you apply more pressure then you will gain more than normal bone groth. to battle this, you NEED some sort of artificial gravity machine...

#73 Re: Interplanetary transportation » Thermal Protection » 2005-08-18 20:51:49

Over here in Scotland a private research organisation conducted a lot of research into what was called Waveriders. They used the Shockwave and where able to enter at a much steeper descent. Most designs where variations of slightly rounded triangles.

that could be something to work on too... something like a partical shield to block against stuff...

#74 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-18 20:42:08

you have to be careful with human bio-chemistry though.... could cause big problems.

I honestly think that we should dig into the ground there at least 200-300 feet deep, and build an infastructure there that revolves on an angle to increase the gravity... all you have to do is set it up on a magnetic rail system which you can import materials to the moon and magnatise it all there....

#75 Re: Interplanetary transportation » Lets walk before we run - Moon first » 2005-08-18 17:34:08

A lot can be done by control from Earth as long as we have some people there. We are getting more and more practice with the use of Telerobotics and with only a small delay of 4 seconds to the Moon, that is nothing.

Certainly I think base infrastructure should be one of the Jobs that Telerobots should do. People we send to the Moon have a lot more important jobs.

I agree that we should have robots there to take care of most of that there, but we still need to be there to take care of basic things like robot repair, heavy duty matinance, and so on...

the cool thing about stuff like this though, is the fact that once we get technology out there like this, then that means that we on earth will also have the same abilities at our disposal.
