hidden_hunter Posted February 8, 2018 Share Posted February 8, 2018 Yeah I had a look at one at the local mall, looks pretty neat. It's also been good to revitalise American made cars here as we've had some shockers over the years that have given them a nasty rep in recent times.

C Carl Posted February 8, 2018 Share Posted February 8, 2018 I can give you an idea of the velocity. It would have had to hit escape velocity. Something just slighter more than about seventeen thousand (17,000) mph. Hope that helps ! Yes , the humor that surrounds this "outta this world" stunt is quite refreshing. I don't think I have been so amused by space oddity high jinks since the alien made pyramids were "discovered" on Mars. The aliens even had built a huge face so we could see what THEY had looked like , when WE finally got there. They preferred Mars to Earth , although the most astute of the "face freaks" here , believe they are among us.

Vila Posted February 8, 2018 Share Posted February 8, 2018 My question about Tesla cars and the likes is how long will the batteries last, how long will replacements of the proper battery design be available and if available for year to come then how much will replacement batteries cost. Or is this another planned absolescence scam. The makeup of gas has changed over the years, but after more then 100 years we can still run our cars on todays gas.

1912Staver Posted February 8, 2018 Share Posted February 8, 2018 (edited) I would prefer the Lotus that the Tesla sports car is based on. Current and past owner of several Lotus automobiles, not a Tesla in sight. All my Lotus cars added up cost less than a single Tesla and both of my present Lotus cars have risen quite a bit in value since I purchased them. Tesla roadster production ended when the supply of Lotus produced chassis ran out. Tesla chose to buy the best chassis it could for its roadster,...Lotus. Over 30,000 Lotus Elise cars produced {base chassis for Tesla roadster} 2500 Tesla roadsters produced. Unfortunately I can not currently afford either Gasoline or Electric version.

The distance to Alpha Centari is 4.3 light years , the brass car would have to be traveling almost 1/10 the speed of light to make the round trip in 100 year, roughly 67 Million MPH.

C Carl Posted February 9, 2018 Share Posted February 9, 2018 Quite correct , Dave. More energy than even Musk will ever be able to harness. No amount of rockets could do it. And how would you structure the trajectory to 'round the horn to come home. Course corrections and deceleration for landing need to be factored. We are talking tourism here. Maybe E. Musk can find a habitable host planet , and not have to ever deal with Earthly concerns again. No wormholes need be invoked , although I will address that after the physics reveal the required energy. - CC Link to comment Share on other sites More sharing options...

C Carl Posted February 9, 2018 Share Posted February 9, 2018 (edited) Wow , Dave ! Hey , I am very impressed. Very , VERY impressed. I have never thrown down this gauntlet before , so you and Greg have shown me I need to be more specific , and give you guys the "yardstick" , the quanta , by which one must measure the energy. The unit of energy measurement which makes sense to us lay men and ladies , is called a "Total Earth Energy Output Year , at present rate of consumption. All the ships , trucks , cars , airplanes , etc. yearly motion combined. Every meal cooked. Every climate controlled interior. Every elevator , escalator , electric motor , diesel industrial application. Every illumination from candles to arc lighting. Entertainment. Servers. Battery powered appliances. Hydro power , etc. , etc. , etc. , etc. , and on and on and on. All power. ALL of it ! TOTAL EARTH ENERGY OUTPUT YEARS AT PRESENT RATE OF CONSUMPTION. TOTAL. So let's say we want to hop aboard an express to take a vacation to tau Ceti f. That is 12 light years away. Accelerate outbound , braking deceleration , and maybe hang out long enough to make a reasonable facsimile of our Earthly mugs. All aboard ! Let's head back. Accelerate , decelerate , home sweet home ! Of course we are a little older , but what a story to tell our young progeny , they not having been born way back at liftoff. Again , let's just figure the energy for the HCCA sanctioned single Brass vehicle transport portion of the trip. We must pay OUR freight , plus life support. That will cost more , let's just quantify HCCA's obligation. I'm pretty sure we can all take care of ourselves. Right ? Whaddaya say ? 1 365th of a total Earth energy output year at present rates of consumption ? Could you muster up and concentrate that much energy ? Not likely. But , I am here to tell you it is more than even THAT ! 1 52nd ? More ! 1 12th ? Nope. It is even more than 1/4 of a total Earth energy output year at present rate of consumption. Should we just leave it at that for the moment ? I started something here before having to take off (sorry) , for the early evening. I cancelled in order to have time to do justice to what I proposed. O.K. I'll stick around. I hope Joe doesn't burst the suspense bubble growing here prematurely. If things bog down I may have to alert him by P.M. Chicken , beef , seafood , or vegan ? I am certain the dinner table banter will be interesting and stimulating , from soup to nuts. Just like the unending fun when old car enthusiasts socialize. I look foreward to meeting the winner !

C Carl Posted February 9, 2018 Share Posted February 9, 2018 (edited) Sorry , Dave. Thanks for bringing this to my attention. The energy requirements for sending mass interstellar distances within a lifetime are more than any society would dedicate. And that even assumes one could concentrate and package that energy. Which is preposterous. That is why we are not including the energy requirements for transporting the fuel. Even for such a high priority payload as the 3000 pound Brass car. You must have some way to express this amount of energy in an understandable format. Let's pick a meaningful, easy to picture and compare , unit of measure. Why not express it as a fraction , or multiple , of : ALL the energy used for all purposes by all of Earths inhabitants and societies during the course of one year. THAT amount is a TOTAL EARTH ENERGY OUTPUT YEAR AT PRESENT RATE OF CONSUMPTION. How many , or what piece of all that GO POWER would be needed to visit a planet around a nearby star ? Lets say a round trip of one hundred years , with a little R&R time. You know , maybe have a barbecue with the E.T.s who have been just "Sitting 'round and waiting for some us folks to drop in". But we will just consider the energy required to send the dry weight of the Brass car we will ride in. READING BEYOND THIS POINT IS UNNECESSARY. MERELY SOMEWHAT RELEVANT RAMBLINGS. THE ABOVE SHOULD SERVE TO SIMPLIFY THE BRASS CAR TO A NEARBY STAR PROPOSITION. E. Musk is capable now of hurling a small payload to a nearby star , one way. After reaching escape velocity from the solar system , I would think he could get there in just a very few tens of thousands of years. Maybe just simply ten thousand years. Pack a VERY large lunch. We can accelerate inconceivably small amounts of matter , protons , to astonishingly close to the speed of light. CERN does it. But MAN does that take some energy. Of that , more later. The high piston speeds in a Brass car are insignificant to the discussion here. Just gotta keep this relevant to antique cars. I wouldn't want to bore everyone. It would even take astonishing amounts of energy to send massless particles interstellar distances. Let's say a civilization wants to watch the broadcast of Super Bowl 53 , while we are watching Super Bowl 100 live. We better get right on the technical task to build a transmitter powerful enough to get a signal there. I think maybe 150,000 - 200,000 megawatts could pull the DX. I don't know. Maybe a quarter of a million - 300,000 megawatts. I don't really know for sure. I could be WAY wrong. This is just a very slightly educated guess. Anyway , it could require a significant percentage of the grid capacity of the entire U.S. Way out there , 47 light years away , they will NOT get to see the Phi Eagles do their just accomplished thing. I see my neighbor , Bloo , is eyeing this thread. He is more astute than I am , certainly could work out the radio transmitter thing. Just extrapolate from the power used by the pirate radio station Wolfman Jack used to entertain us old timers way back when. Remember "The X" , "The MIGHTY X" , XERB just south of the border ? I seem to remember the great reception at times. I am pretty sure Canada could tune in if skip was right. Even farther certainly from time to time. Am I right in remembering 50 kW? Something massive like that. I think they were running 100 kW for a while. Now Bloo would be easy to feed. Just on the other side of a small hill from me. Energy requirements for that round trip are easily within budgetary necessities. Thank you guys/gals who are interested in this aspect of the Brass Car Era. Particular thanks to Bob for initiating this fascinating thread ! If I remember correctly , Joe is a Ph.D rocket engineer. He might have thought about this aspect of Brass cars. I hope he drops in to give a reality check. - Carl Edited February 9, 2018 by C Carl Clarification (see edit history) Link to comment Share on other sites More sharing options...
Spinneyhill Posted February 9, 2018 Share Posted February 9, 2018 (edited) The usual way is to use nearby planetary bodies to sling the vehicle off at speed, using centripetal acceleration. It one could do that a couple or several times, the amount of energy required would be reduced considerably. The other alternative is to get Scotty to beam it there.
