MythBusters has shown how hard it is to get a water heater to explode. Ya gotta bypass and remove a few safety releases and try hard to make it work, and they always did it with electric water heaters. They had some great water heater episodes. They got one to rocket through the roof of a two story house.

Yep, that's all I remember, their hot water heater rocket. Not that I've ever heard of it actually happening in the wild.

Seems it would take quite a bit of propellant to launch 40 gallons of water. But I ain't no rocket scientist.

The 40 gallons of water is just the propellant. Only the case is the rocket. They found a few instances of it happening in the real world. It was always someone that had done some modifications to the plumbing. If the high pressure fitting starts leaking, ya don't wanna just put in a plug in its place. And don't remove the temperature limiter, unless you like rockets.

Water isn't compressible, and there shouldn't be any air gap in a water heater, so he only time it could "rocket" is if the wa wa turns to steam.
The desire to expand would create thrust.

Seems to me that you'd have to screw up pretty bad to make steam.
Stuck open thermo-stat, failed pressure/temperature relieve valve, etc.

But murphy says is can happen.

Murphy and the Myth-Buster!

Dang Photoshop, ARGH.

I have a admittedly large image made by our mapping software.

http://forums.pelicanparts.com/uploa...1545935918.jpg

I can open it in Photoshop, but that is all. I can save it as a Photoshop large document format, but that is a format no one else uses. I will have to cut it up into 8 or so pieces, and than reassemble the parts and then make a tiff file from the mapping software. We have several packages that will open and do what is needed, but they are not image editing applications. I want to clean up a few ghost cars that are created when the multiple image are all made into a large single image mosaic.

Photoshop will not allow anything larger than a 4 GB tiff file. Like it is a law or something. The mapping software does not care. I can make em big. ARGH. Damn Adobe.

Would it help if you got a bigger monitor? ;)

I really think it is because Adobe want to keep it backwards to older version of Photoshop. We often deliver the huge images the client ordered, and a few days later get an email asking for a smaller version. It blows me away that some companies try to use a computer designed to do email and Microsoft word, and try to do mapping or engineering with it., or they are still using Window XP.

We don't upgrade our software for fun, and building a new computer is a little bit fun, but the money we spend is NOT just because it might be cool.

I was excited when I went from win 3.0 to 95.

I was excited when I switched from 95 to XP.

I was pissed when they forced me to give up XP.

I was really pissed when they forced me to install win 10.

Win 10 has taken some adjusting on my part. In the end, it is THE standard for most businesses. Today's software is written for it. Much of our mapping software requires Win 10 Pro 64 bit. We have it running and it is stable on 11 different computers.

My biggest issue with it, is they are convinced every user is a 20 something that wants to play games and sync everything to their phones. I don't have one game on my system, and it takes Google searches to kill off all the games and especially X-box crap.

And as much as they want me to sync with my phone, and use the cloud, I will fight it. The ironic thing is I have three computers on a super basic peer to peer network at my house and seven computers at my business partner's house. Every update seems to kill the simple peer to peer sharing. We have to fight to get the folders to share again. Just frustrating as heck.

Yup. I would like my phone to work more like my 'puter.

I don't want my 'puter to work like my phone.

What sucks is we use Win 7 Pro here at work and if we "upgrade" to Win 10 we have to go to the Enterprise version or lose a lot of management functionality. Not a fan of 10 at the moment but we have a few computers at home with it. Most of those at home are Win 7 Pro still.

I'm into vibration analysis, been getting more and more into modal analysis and ODS analysis. Animated and everything. Mobius institute, Category III card carrying.


I have 5 data collection/analyzer boxes that are 8 years old, and the manufacturer said are obsolete, gotta buy the new and improved version!
I said nope. They work fine.

They said the old ones aren't supported by the manufacturer anymore, gotta upgrade!
I said nope. They work fine.

They said, the new win 10 database and software is available, but it only works with the new analyzers and the old software/database ain't compatible with win 10.
Bastages.

Gun to my head, gotta submit a req. for $165,355
But that's for six 4-channel analyzers, might as well have a spare.

Sammy, that is typical for all software and hardware regardless what it does. We have one software platform that we had to have for us to make what the clients want. If we don't keep paying many thousands of dollars every year, it simply stops working at all.

One reason we have the aerial camera platform we do have, it is pretty much a one and done purchase. No repair contract. The big companies have the state of the art Leica made system that are over a million bucks to buy, and the maintenance contract is $60K per year, forever.

Yup, happens all the time but it ain't right and I don't have to like it.

Several years back we had a compressor beta analysis machine made by Dynalco.
It was older but worked well.
Their competition was a company called windrock, basically only two shows in town.
So Windrock buys dynalco, and declares the dynalco equipment obsolete, everybody gotta buy $70k worth of Windrock stuff.

I said nope, not gonna do it.
Some of the dynalco techs who were laid off by Windrock started a little service company so I had them service the equipment.
Worked out well.

We had an old scanner at my last job that was only $70 grand new. It was made by a company is Austria, and was typical German engineering. It made cool sounds, and worked great. The company was purchased by Microsoft. They reduced the service staff to one guy for the entire world. Really, all of planet earth. He was based in Italy, so we would have had to pay the airline cost, hotel cost, and the $800 per day plus any parts needed for the repair.

It was all off the shelf parts, if the Goolgle-fu was strong. We found the source for tiny electric motors and they were mounted with tiny screws and red Loctite. We started fixing it ourselves with lots of effort. We broke down and ordered a new bulb for it from Microsoft. It was $550 bucks. We used our powers of Google and found the manufacturer, and ordered them for $45 bucks each.

It was working great when the company was shut down by the idiot son of the previous owner. Best thing that ever happened to me.

Had XP, then 7, now 10. They were all just different. And yes, every once in a while I have to re-enter my username/password on shared services. Nothing changed, don't understand and it's not local sharing either Glen. And every once in a while I have to delete and re-create the network share. Also every time win10 updates my win10 computer slower and slower, especially rebooting. NOT doing a darned thing different from when i was using xp.

Think at work there is a mixture of xp, 7, and 10 depending on when they bought the computer. They are trying to replace everything over 4 years old. But really only do anything unless the user complains how slow their computer has gotten.

Ran some errands in the GTS.
Impressions...
That thing really is small and low, yet very cumfy! A bit more than the turbo.
Can fit a surprising amount of stuff in the hatchback. Not as much as the turbo.
Sure sounds good, rev, rumble rumble. Better than the turbo.
Since tuned well when accelerating from stop to over 25 mph it wants to spin tires.

It ain't the car that wants to spin the tires. It is the loose nut behind the wheel, and his right foot.

Yeas back one of my buddies had a Mopar muscle car, whit a crazy high compression engine it it, and huge intake and carbs. We were out and about in the rain, and it was terrifying. Just getting rolling at idle and touching the gas caused wheel-spin. With almost any movement on the gas, the engine was roaring. I called it the light switch, just on or off. I was glad to get home.

Interesting site. I remember going to engineering clients offices and seeing a few guys drafting. And a local reproduction shop just REEKED of ammonia for making the blueprints. I was had to go in there, the ammonia smell was so strong. Now that same shop is basically order free. Everything is digital and fast and quiet.

My former boss worked at a electrical plant in the 1950 and 1960s. He said one of the draftsmen was drawing up a plan of the place and had spent months getting it perfect. They took some black paper and cut it in the shape of a giant drip of ink, and put an empty bottle of India ink at the top of the table to make it look like the ink had spilled on his drawing. He came back from the bathroom and almost had a stroke. After it was over he admitted he had been "had" and could see the humor, but she threatened everyone with bodily harm if they ever do it again.
