Professor: Young People Are "Lost Generation" Who Can No Longer Fix Gadgets

wagnerrp Re:Dupe (840 comments)

Now wait a minute. I thought BMW had hardpoints on the side of their vehicles, and a special jack that fit those hardpoints, specifically to make it easier to jack up.

The Magic of Pallets

wagnerrp Re:/|\ DeVry business grad. (250 comments)

You've still got a fairly expensive asset sitting idle.

Perhaps, but look outside any active distribution center and you'll find acres of idle trailers. I know Walmart even uses them as long term storage.

Then there's the extra labour to move one box at a time

If you're already moving one box at a time, because you're building the pallet, you may as well move one box at a time directly into the container. That was the whole point I was trying to make. There is no extra labor. The container itself is the unit of transport, rather than the pallet.

with ladders. You might be eight feet tall, but most people aren't.

Large molded plastic step stools, actually.

The Magic of Pallets

wagnerrp Re:Like many inventions ... (250 comments)

My visibility may be skewed for only facilities with conveyor systems, but every high volume distribution center I've seen either does fluid loading, is in the process of transitioning to fluid loading, or is seriously considering fluid loading, rather than pallet loading.

... two trips over one,

Unless the previous trailer just waits around until the next one is dropped off.

And where is this happening?

Anywhere you're shipping freight between two of your own facilities.

The Magic of Pallets

wagnerrp Re:Like many inventions ... (250 comments)

You can unload 3,000 cases of palletised goods far faster than two or three people stuck in the back of a semi-trailer can put them on a conveyer belt. It takes a warehouse 20 minutes to unload a full 26 pallet load semi-trailer, it takes 2hrs to unload 1500 cases on a conveyer belt.

That's only relevant if the driver and truck has to stay with the trailer. In a major distribution network where it's the same company on both ends, that does not apply.

The Magic of Pallets

wagnerrp Re:Like many inventions ... (250 comments)

Sure, pallets take some vertical space, but the amount of space taken is small compared to the ability for one person to move close to two tons of cargo single-handedly across smooth floors with no more than a jack.

That requires one person and one hand truck or fork lift to shuttle each pallet of two tons of cargo back and forth. It's cheap, but it's very low throughput, and it doesn't scale up to high throughput well. If you need high throughput, you're going to use conveyor. You use pallets for storage, for items that cannot be conveyed, or for things like LTL receiving where you can't keep the trailer, and don't want to hold up the driver while you hand unload.

The Magic of Pallets

wagnerrp Re:Like many inventions ... (250 comments)

It takes time to build pallets. It takes time to break apart, resort, and rebuild pallets. It costs money to repair and replace the pallets themselves. Pallets require extra ceiling space to actually pick them up and put them into a truck or container, resulting in wasted volume in that truck or container. The logistics industry is quickly moving away from pallets for everything but long term storage.

Just make sure they're not chemically treated before tossing them in the fire.

Geoengineered Climate Cooling With Microbubbles

wagnerrp Re:What percentage... (114 comments)

Ideally, nothing. Groups are already investigating the use of cavitators along the hull to reduce surface friction and fuel consumption. If that pans out, this would basically be a bonus effect.

The Dominant Life Form In the Cosmos Is Probably Superintelligent Robots

wagnerrp Re:Well, duh (391 comments)

There's no reason biological organisms cannot have an indefinite lifespan. Stasis would only be necessary for the purposes of reducing energy consumption and preventing boredom, which would both be issues in a machine intelligence.

Sir Richard Branson Quietly Shelves Virgin Submarine Plan

wagnerrp Re:Can't say I'm surprised (47 comments)

Branson has a track record of seriously underestimating the difficulty of the challenges he picks. Plus he seems to believe he can replicate serious engineering achievements - eg space flight - on a shoestring budget.

You're overestimating the capability of SpaceShipOne/Two. It goes to space for all of a couple minutes. It does not go to orbit. The engineering requirements aren't nearly as tough. We've been sending unmanned vehicles up there since the early 40's, and manned ones up since the late 50's, back when NASA was still called NACA.

Sir Richard Branson Quietly Shelves Virgin Submarine Plan

wagnerrp Re:No so easy as throwing money at it, is it? (47 comments)

The Apollo programme was 4% of GDP, by itself

The Apollo program cost ~$20B, over the better part of a decade, during a time when the US GDP was rose from around $600B to $1T. So, it used roughly 0.3% of the GDP over that time period.

High Temperature Superconductivity Record Smashed By Sulfur Hydride

wagnerrp Re:Oh Carbon (80 comments)

There's even a type of energy storage system you can make with superconductors - one of the highest power density and efficiency energy storage methods known to man.

The ultimate capacity of one of these systems is on the par with supercapacitors, and an order of magnitude lower than traditional chemical batteries. Their high power, low capacity, and functionally unlimited cycle life make them useful as a transient power filter, rather than a meaningful energy storage mechanism. Their sudden and nearly instantaneous quench makes them downright frightening as a sizable energy storage mechanism.

Material Possiblities: A Flying Drone Built From Fungus

wagnerrp Re:Fungi as instruments (52 comments)

You're suggesting that instead of giving it some simple sensors and a radio, we task a satellite capable of real-time spectrographic imaging with sub-decimeter resolution in order to spot the changes in color of some oversized flying test strip?

Who Needs NASA? Exoplanet Detected Using a DSLR

wagnerrp Re:Billions and billions: (108 comments)

This site is based in the US. Therefore, the convention it follows should be that of the US. Any use of a comma as a decimal delimiter here is simply wrong.

Besides that, the use of six digits when only two or maybe three are actually significant is just clumsy.

Denmark Faces a Tricky Transition To 100 Percent Renewable Energy

wagnerrp Re:Use the money you save (488 comments)

Like I use energy to lift a stone, and I get 100% of that energy back if the stone drops.

No body is fully elastic. You will have infinitesimally small energy losses due to changing internal stresses in the two bodies. You get very very close to 100% recovery, but not 100% recovery. The energy is still there. It hasn't escaped your hypothetical closed system. It is simply not recoverable in a useful form. It is disordered. Reversible processes are those "special cases".

Of course doing so has the side effect that no one will give you loans because your currency is too unstable to be of any international value.
