Tesla Cybertruck

Most here have undoubtedly seen Elon Musk's new Tesla Cybertruck; in case you haven't, here's the link to the promo: https://www.tesla.com/cybertruck

More interesting than the Cybertruck has been a recent Tweet, stating that there's another model under development with a sealed atmosphere and pressure doors--designed for use on Mars!

Re: Tesla Cybertruck

Yes I heard that...that should protect against micrometeorites!  Clearly the tires would have to be redesigned.

Re: Tesla Cybertruck

Yes. The tires certainly aren't compatible with Martian conditions. Ultimately, a tracked vehicle would be in order.

Re: Tesla Cybertruck

I'm with you on that - tracked feels right.

Re: Tesla Cybertruck

The big thing for the truck is that it does away with those large gasoline and desiel engines that have a high particulate output of carbon in the exhaust.

Re: Tesla Cybertruck

Don't know if anyone else picked up on the comment by Elon, that they were working on a model for use on Mars? One that could be pressurized internally.

Re: Tesla Cybertruck

I hope the glass gets more testing before we go in it without a space suit.....
Its about time that Nasa gets some egg on there face....

Re: Tesla Cybertruck

For SpaceNut re #9

Your observation deserves follow up ...

I'm pretty sure the window DID NOT BREAK  .... That was safety glass, and the demonstration showed that a person inside the cab would have been protected from a projectile of the mass and the velocity used for the demo.  Safety glass is designed to shatter while the plastic layers hold the pieces together.

A quick Google search confirmed that the safety glass I'm thinking of is indeed made with a plastic layer between glass.  However, I learned that there is another type of safety glass that is made only of glass, which is designed to shatter into non-lethal chunks.

From my observation of the Tesla truck demo, since the window appeared to hold together, I'd assume it was made with one or more plastic layers.
The person inside the cab would NOT have lost air pressure, if the plastic layer held.  More details about the performance of the window would be helpful, and if someone can provide them I would appreciate seeing them.

Re: Tesla Cybertruck

The front windshields do have safety glass but most auto windows on the sides are tempered glass but in the regards to safety it adheres to the glass but still can puncture and allow the internal atmosphere in a vehicle on mars to escape. The mars vehicle would want a secondary layer of safety glass with a gap to keep full failure from happening.

Re: Tesla Cybertruck

For SpaceNut re #11 ...

I ** think ** the point of Elon's demo was to show that unlike (as you say) most auto windows, the truck side windows are made of safety glass.

Your design of double safety glass seems to me to be an ideal candidate for rigorous testing, to be sure that the extra expense and extra mass are actually needed.

However, it is EXACTLY that kind of forward thinking that is needed to arrive at a practical solution.

I'd like to see test results in a vacuum chamber with "normal/Earth" atmosphere on the inside of a test article.

The goal would be to accept some level of punishment before pressure is lost.

Science fiction writers have been imagining diamond windows for several decades now.  In the current age of rapid nanotechology advancement, it would not surprise me to learn that someone somewhere is working hard on a fabrication technique for that particular branch of carbon capability.

Re: Tesla Cybertruck

The outside glass would have gorilla glass plastic adherred to the outside to add an addition layer of protection such as what we use on a cell phone. Obsorbtion of impact is important to deterring breaking of the glass.
