If they are going to grow cars in arbitrary boxes, they might as well make the boxes more interesting. Next year, cars should be powered by a 49 degree V7, follow a trike configuration with one front and two back wheels, and only the front wheel can be driven. There, that should be interesting to watch.

What other manufacturer sat on a deadly recall for over a decade, knowing that people already died? For bonus points what other manufacturer has recalled more cars than they made over a 6 year period? Sorry dude, looks like GM is in a league of its own.

Why the trellis frame, when you can get more from a hydroformed unit? Is it just for looks?

Dude, GM made a safety system that didn't function as designed. That is not in question. Now people can argue all they want about who was responsible for those deaths, and it will never change the fact that GM designed and built a bad safety system, knew about it, and did nothing to fix the problem for a decade. So…

The ignition switches were broken by alcohol?

When Toyota is recalling more cars than they are making, get back to us.

Who was the camera man?

Who was filming? Because they certainly knew what the target was. Was ISIS informed of the target of our airstrike? Or was it not the least bit suspicious about some guy pointing a camera at a cannon a minute before it is bombed, and then walking away whistling? Something doesn't seem right here.

A typical highside happens on pavement, during corner exit, when the rear tire looses traction. In this case he ran out of track on corner entry. It's almost not the same thing at all

Wouldn't it be relatively easy and inexpensive to install an alarm that monitors the pressure inside of an aircraft, and alerts the pilot of the need to descend? As I understand it, the biggest problem with hypoxia is how long it take someone to realize that something is wrong, while an absolute pressure gauge is a…

Do you know of anyone that manages to print a mold to run polycarbonate, abs or nylon? I'm struggling with that right now, even if I completely disregard longevity concerns, I can't quiet figure out how to make sure the mold seals properly on the parting line, around the shutoffs, and ejection pins. Got any advice?

It may well be the neatest, but in a ways its one of their least useful features. 3d printers are unlikely to take over mass production anytime soon. If you design an engine block that has unique geometry that can only be produced by a 3d printer, that engine will never end up in most of the cars on the road.

Today's low end printers are around $2,000 and produce parts that have neither the precision not the mechanical properties to be something other than a demonstration piece. However, if I can get a printer for less than $500 with the same capability, I'd get it just so the kids can have something to play around with.…

Ah, but being able to print the mold or the machining fixture would sure shake up the game, wouldn't you say?

You still need to factor in design time/cost, testing time/cost, and the necessity for iterations. So while a rocket engine can be printed in any size, each size will probably have to undergo considerable and expensive testing, so it will make sense to only have a few tested sizes to pick from. Or in the case of a…

I've been wanting to prints a mold cavity for a while. DMLS leaves behind so much machining work that the savings are negligible. Next project is to try to print cavities from PEEK to make very short run injection molding tools at low cost. We'll see how it goes, the precision of printed parts is still lacking making…

Of course it is going to be most beneficial in the factory, and that's hardly understated. Let me elaborate:

You can bet these thing will be extremely expensive to maintain... You'd think the town would be better off with an extra officer.

Why, do you think hundreds of terrorist soldiers are going to sneak into NY harbor in stealth submarines like a bad Chuck Norris movie? Even if anything does happen, it will be one or at most 3 guys blowing themselves up in a subway somewhere. First anyone will hear of it, the whole thing will be over. The MRAP will…

While it is a very clever and elegant solution, the amount of power that can be harnessed is pitifully low.
