New York to LA in 45 Minutes!!
And when the power fails? Friction at 6500 kph would melt that sucker fast.
And when the vacuum fails? When something goes wrong at 6500 kph, it really goes wrong big-time. This isn't a new idea, and from what I've read, hasn't been realized because in reality, the risks are too great.
Mieders Alpine Coaster - Frustrated Guy Crashes
OK, I watched at full res/screen a few more times...they all slow down and stop again shortly after the 'crash' and she's all floppy, then her friends release their brakes but she holds hers a few seconds to give some space between her and the one in front, then she releases her brake, partly. All that time she's flopped over like she's out, but she must have some control or she would still be on the bumper of the guy ahead.
I don't mean to say I think it didn't hurt, just that I didn't think she was completely knocked out when it looked like she was. So I'll retract "faking it" and replace with "exaggerating it".
Also, I don't think she did it on purpose, but she rear ended the guys (apparently her friends) in front of her who had stopped, again.
Admittedly, right after the crash she is on his bumper, but he does not seem concerned in the least and leaves her flopped over, like he knows something. She may have really been out for a few seconds, but I think not as long as she made out. If she is really hurt, isn't her 'friend' still the real douchebag? First for stopping short in front of her without any warning, causing the crash at least in part, and second for not helping his friend when she rear ended him 'unconscious', but instead just riding on?
The guy in back was 'tailgating' a bit, but did not seem to hit her intentionally and had no chance to brake, and may have not had enough time the first time he hit her either. Those brakes are just friction brakes, they don't stop on a dime, especially if you're a full grown man. (agreed, that's a good reason to not tailgate at full speed, so they're all douchebags?)
I thought she was right on the tail of the guy ahead of her. It seemed like she was basically connected to his ride for the duration of it.
I accept I could be wrong. I'm not so suspect of people as that, and definitely didn't have that conclusion. If I were to extrapolate on that line of thinking I would still disagree because I'd expect anyone who would have the gall to do that in the first place wouldn't then get off the ride and walk meekly away knowing that the guy who rammed her that hard (and it was hard, regardless of the effect) was going to be stopping just behind her.
All types of people in this world, so could go either way, but I personally think the assumption she's faking it is absurd. The number of people who are that shitty is pretty low, at least statistically and empirically, and I doubt someone like that would enjoy a nice roller-coaster down a hillside in the first place.
How To Break Out Of Zip Ties.
You can also use a shim to release the catch on the ties, or if you have replaced your shoelaces with paracord you can use them as a friction saw by bicycling your legs.
Both of these methods are easier if you have a little slack to play with, so don't tighten your own restraints unless you are certain the zip ties are thin enough for you to break successfully, or you don't have anything available to use as a shim or saw.
Edit: To clarify, I don't mean to suggest shimming or sawing are easier than snapping (Though with very thick ties it can be). I mean it is easier to shim or saw with a little slack, than to shim or saw without slack.
Chompy the Shark
Shark didn't get that on either, at least not while it was still hooked. Scary, scary, it takes about 20-30kg fish to drag you under water if you're both swimming, on land we got friction and weight so we can take larger prices than ourselves.
So now the shark has a hook inside its belly ?
Burning Van Just Cruising Down The Road
I think he's got something caught under the front axel that's burning up from the friction. The vehicle itself isn't on fire. Yet.
Why cant non probationary, non gem, members *dead/dupe/rel (Wtf Talk Post)
Sounds like a good idea. Sometimes I post *dead or *blocked in the hope that another user will notice, and if they do they've usually upvoted my comment before doing it themselves; then I upvote them back.
Perhaps points can be given for a senior member invoking an action on behalf of someone else.
At a minimum Siftbot should let me know why, and what I can do about it. "not privileged" on its own isn't very useful, and I'm not told beforehand that that would be the result of my actions, so it's all friction.
I'm not saying Siftbot needs to change its cranky ways, but it could be a little more helpful:
Invocations (dead) cannot be called by L0cky because L0cky is not privileged - L0cky needs to get some more stars.
Would it be better if, instead of just saying user is not authorized, @siftbot said "pending review" with a link to click to allow privileged users to complete the action?
Evolution of Perpetual Motion: Free Energy Generator
*nochannel *engineering *fail *lies
This is not generating any free energy, and if left running will eventually stop due to losses from friction and (what I'm guessing is) the spring in the little bouncing arm.
[edit] That said, I should probably leave the explanation to those with a more thorough knowledge of physics and the desire to *debunk this.
Solar Roadways
yes i'm not saying the roads are consistent, only more consistent than the shoulders.
Roads are generally no less than the width of 2 cars. Some consistency cuts manufacturing costs which will eventually be a factor in EOREI (energy returned on energy invested). Can it work....uhhh dunno. Many roads are created sectionally as it is. which is good. but yeah i have to worry about chains, rocks, studded tires....
Legally you wouldn't have any "takings" issues.
But IMHO, most technical solutions are further away than the more immediate solution - education, family planning, and worldwide contraception programs. the real problem is that there are too many people on the planet. We are consuming more of the ecosystem than we replenish. we need to USE less, but that necessarily means less people...which = more resources available per person, and less emissions.
Meanwhile keep working on the tech side to create efficiency.
Conceptually however, it is interesting to look at roads in energetic terms. They do produce all sorts of heat (and friction) and kinetic energy.
The most consistent thing about the roads themselves is that there are cars on them. More so with parking lots. The Gas Station had way more than enough roof area to cover it's electricity usage, no need for putting panels underneath parked cars.
A light coat of dust on panels can decrease their efficiency by up to 50%... there would have to be a CONSTANT fleet of road washers, slowing down traffic. At least with roof/road mounted panels they can be tilted to shed most of the dust/pollen that accumulates, though they do have to be washed monthly.
And then there's the question of what happens with accidents. Sure, the tensile strength might be as strong as steel, but it's because of the enormous pressure it's under. it only takes one flaw in the surface to make the glass susceptible to shattering... just the thing to make car accidents more hazardous.
Solar Roadways
Honestly though, this idea is silly, why not just have panels that run parallel to the roadways? That way no roadway has to be closed down for replacement and the material engineering nightmare of creating a high-friction, transparent, strong material won't exist.

Chinese Farmer Creates Wind-Powered Car
That is the dumbest thing I've ever seen.
Don't people know you can't get energy from nowhere? The fan produces friction, that friction creates electricity, but it also slows the car down, the amount produced will never surpass the amount of energy spent pushing the car forward. Additionally there is inevitable loss in the generator, wiring and batteries.
It is impossible to build a wind turbine generator on a car that increases efficiency through wind generated by the vehicle's own travel.
Everyone involved in the production of that bit needs remedial physics classes.
