Good point.

Maybe, an investment in Depends undergarments, or airsick bags might be a good idea.

In Dave's case, maybe just seal him up in a body bag.

Name a place and time, big guy.

I'm not anonymous. Anyone can come visit me. I live in East 4th between Second and the Bowery. Should take five minutes to find out my address. Indeed, I've taken Marty to lunch. Of course Marty's a nice guy, not a Troll like those two, or an A-hole like you.

I'm officially in your ignore list, remember? How on earth could you fall for this!

You really need to take a break, bro.

I took you off about a week ago. Are you saying I should have made a public announcement? PM'ed you?

A card would've been nice.

You're an A-hole, the others are trolls.

Anyone who wants to find out if I'm BSing has two choices. They can either visit me, or make a bet with me, that I can't do what I claim to be able to do. Loser quits the forums forever. And I can post newspaper articles about myself in a flash - So take me up on one of these alternatives.

Even on the little thing of you bench pressing 300 lb?

I thought this story about an idea developed by Elon Musk (Telsa) was interesting. From the link:

"Serial entrepreneur and billionaire Elon Musk unveiled design plans for his Hyperloop -- a superfast transport system that could cut the travel time from Los Angeles to San Francisco to 30 minutes, and cost a fraction of the currently proposed high speed rail project.

Musk, a co-founder of PayPal and the man behind commercial space transport firm Space-X and electric car maker Tesla (TSLA), said up to 1,000 employees from both Tesla and Space X worked to come up with the idea, which is basically an elevated tube which moves travel pods at nearly the speed of sound.

In a technical paper published Monday, Musk said his idea is similar to the "old pneumatic tubes used to send mail and packages within and between buildings," but would operate under much less pressure to save on energy.

The cars would be pushed or pulled through the tube by a series of electric motors, possibly similar to the ones used by the Tesla Model S. Each car would be mounted with a fan in front to move the air out of the way. The air itself would then be directed underneath the car, forming a cushion on which it would ride. The entire thing would be powered by solar panels mounted on top of the tube.

Related: Elon Musk's greatest hits.

The tube itself could be built above ground, roughly following California's Interstate 5 highway from Los Angeles to San Francisco.

Musk said it could cost less than one-tenth of the planed high speed rail system in California -- a project that's estimated to cost $70 billion. It would also be six times faster.

In fact, it was the high cost of the California train that prompted Musk to research the Hyperloop in the first place."How could it be that the home of Silicon Valley and JPL -- doing incredible things like indexing all the world's knowledge and putting rovers on Mars -- would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world," he wrote.

Experts say Musk's idea is technically feasible, but will be hard to implement primarily due to the cots of developing a demonstration project and the time it will take to get all the permits."

Looks interesting, especially if it can be done for the cost and the specs he has laid out.

Thoughts................

As a technical exercise its very cool, but not much use if it cannot handle the traffic density of a high speed rail. Also the long term maintenance and running costs are not really mentioned.

I totally agree that there are a lot of things to work out and that this is more of a concept used to sell an idea than anything else at this stage.  It is good, however, that someone is thinking outside the box.  That is how we sometimes get some great inventions, commercial applications, etc.

Rail is a major up-front investment, but it has a very long lifespan to pay it back, and trains can be upgraded continuously during that period.

True, but it seems to me that this approach has some of those favorable attributes as well.

The real issue is cost per passenger mile over 20 years. I don't see the figures for that.

On p. 6 of 'The Technical paper' linked above the go into it a bit "In this study, the initial route, preliminary design, and logistics of the Hyperloop transportation system have been derived. The system consists of capsules that travel between Los Angeles, California and San Francisco, California. The total trip time is approximately half an hour, with capsules departing as often as every 30 seconds from each terminal and carrying 28 people each. This gives a total of 7.4 million people each way that can be transported each year on Hyperloop. The total cost of Hyperloop in this analysis is under $6 billion USD. Amortizing this capital cost over 20 years and adding daily operational costs gives a total of about $20 USD (in current year dollars) plus operating costs per one-way ticket on the passenger Hyperloop."

It's tough to plunk down new rail lines. That's why existing rights of way are never discarded. Won't this require new paths to follow.

I wonder if they gave any thought to an adaptation of the systems in that show, "Punkin Chunkin'".

If a train blows it's motor, you coast to a stop. What kind of back up measures are there for this concept? Traveling at the speed of sound, and then suddenly "bottoming out" is gonna be a mutha...

There's no motor in the pods. Magnetic levitation will use permanent magnets, so a power outage won't cause them to bottom out.

Still, a scenario where the loop is stopped, is worrying. The pods need emergency brakes in case the pipe is compromised (a plane came down on it, or a sinkhole opened under it, or somobody's customized sneaker blew up a pod, or a lightning strike demagnetized a portion of the track, etc, etc, etc.). They also need a way to evacuate people from the stopped pods.

Neither emergency brakes nor evacuation manholes seem like insurmountable obstacles though.

Whoops, it's not magnetic levitation. Read a wrong article. Never mind

I don't have an answer. I have no idea. But when I read "speed of sound" the possibility of something "going wrong" seems to be a valid question...

Sooner or later something WILL go wrong, and I'd like to know how the emergency systems work, AND do they cover all possibilities.

There's no way they'd cover "all" possibilities, but it should be possible to make the system significantly safer than the normal high-speed rail.

For instance, a problem with one pod (or with a terminal) won't cause a "domino" effect of other pods crashing into it - they'll have emergency brakes and deployable wheels.

The tubes will have emergency access and pressurization ports.

(Breathing 0.1% atm inside a steel tube heated by California sun can be detremental to one's sinuses).

The "magnetic levitation" was a common speculation, before the plans were revealed. Turns out, it's "air bearings" - a compressor/fan system that pulls the (very thin) air from the front of the pod and blows it underneath the pod (creating an air cushion like in hovercraft) - and partially behind the pod (relieving the pressure built up in front of it by its high speed).

Here's the proposal (pdf)

They actually put a lot of thought into safety - just search the .pdf for the word "safe".

Thanks, I missed that bit. However a 30s gap at aircraft speed doesn't sound particularly safe.

For a fully-automated system, that's a lot of time.  It takes 20 seconds of 1.4 G deceleration (mild discomfort) to go from 600mph to zero.  In a true emergency, 3G deceleration (not comfortable, but survivable) would stop a pod in under 10 seconds.

I'm surprised at the reaction to a simple statement of fact. Now it may be that I CAN'T press 300 pounds now. Long time since I worked out with weights. On the other hand, last Winter, I had to lift a 223 pound motor over my head, slip it into it's housing, and then while holding it up with one arm, catch the bolts to hold it in place.

I suppose you doubt that as well? Yet it's part of my job.

I'm not sure, after being the top poster for a decace and all. Oh, wait, that was you?

If you wont take the bet, than you really ought to STFU. Don't you think that would be appropriate?

Ok let's do this thing! Since you're too scared to name a time and place, I will.

Tompkins park. in front of the basketball court. Thursday. 01:00 AM.

I mean I offered to post PROOF, not merely my words. Of course you WON'T STFU, and you WON'T take the bet - And thus you prove that you ARE a A-hole.

How old.... did you guys say you were - 110- 125 or so collectively.  Kinda old for this stuff perhaps?

Yeah, it might be that you can't. Nothing wrong with that, though. If you could, you'd be competing with American recordsmen of your category:

Yeah, I was pretty sure that's close to a record. Of course it's NOT a record.

Particularly if it never happened.

Long time since I worked out with weights. On the other hand, last Winter, I had to lift a 223 pound motor over my head, slip it into it's housing, and then while holding it up with one arm, catch the bolts to hold it in place.I suppose you doubt that as well?

How could I? that is totally believable too.

Yet it's part of my job

Sure. Here's a suggestion: make this part of your equipment. It's a game changer.

Shows how little you know about repair work. Good for you. You know nothing about many subjects but are an expert in all of them.

But do me a favor, and take me up on my bet.

Anything for you, Dave. What's the bet? Because, it certainly ain't anything related with bench pressing, is it?

No, just proof about how tough I am.

Re: The Hyperloop

I thought this story about an idea developed by Elon Musk (Telsa) was interesting. From the link:

"Serial entrepreneur and billionaire Elon Musk unveiled design plans for his Hyperloop -- a superfast transport system that could cut the travel time from Los Angeles to San Francisco to 30 minutes, and cost a fraction of the currently proposed high speed rail project.

Musk, a co-founder of PayPal and the man behind commercial space transport firm Space-X and electric car maker Tesla (TSLA), said up to 1,000 employees from both Tesla and Space X worked to come up with the idea, which is basically an elevated tube which moves travel pods at nearly the speed of sound.

In a technical paper published Monday, Musk said his idea is similar to the "old pneumatic tubes used to send mail and packages within and between buildings," but would operate under much less pressure to save on energy.

The cars would be pushed or pulled through the tube by a series of electric motors, possibly similar to the ones used by the Tesla Model S. Each car would be mounted with a fan in front to move the air out of the way. The air itself would then be directed underneath the car, forming a cushion on which it would ride. The entire thing would be powered by solar panels mounted on top of the tube.

Related: Elon Musk's greatest hits.

The tube itself could be built above ground, roughly following California's Interstate 5 highway from Los Angeles to San Francisco.

Musk said it could cost less than one-tenth of the planed high speed rail system in California -- a project that's estimated to cost $70 billion. It would also be six times faster.

In fact, it was the high cost of the California train that prompted Musk to research the Hyperloop in the first place."How could it be that the home of Silicon Valley and JPL -- doing incredible things like indexing all the world's knowledge and putting rovers on Mars -- would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world," he wrote.

Experts say Musk's idea is technically feasible, but will be hard to implement primarily due to the cots of developing a demonstration project and the time it will take to get all the permits."

Looks interesting, especially if it can be done for the cost and the specs he has laid out.

Thoughts................

Yeah, I'm thinking...

I wouldn't like to be on the first one that crashes

Good paper study and some hand-waving but I'd like to the cost breakdown study. As I understand it the high costs of the California High Speed Train are driven by expensive right-of-way purchase and the stations costs that are in the cities and not out in the orchards. I don't see that putting the train  in a tube or on tracks make much difference in those costs.

Moreover the tube technology is not even developed yet, AFAIK, and I'm sure those development costs won't be cheap.The 800 mph might be just be a pipe dream which so far it is. Has anyone seen one run that fast?

An already developed and operating Magnetic Levitation System like the 280 mph Shanghai Maglev Train seems like a better choice over the current California High Speed design.
