CHP Officer not happy when you go 90 mph

newtboy says...

I sure am. Spent between 83 and 96 in the bay. So glad to be out of that now.

73 Charger….nice. A good friend spent all high school and then some building one of those, massive motor with blower, spool in back, etc. It was gorgeous and mean. I think he wanted to street race it, but the first day he ever drove it the rear end went around the front on an off ramp and he stuffed it into a freeway column totaling it. Tragedy.

I followed suit with my legend, fishtailing head on into a K rail at 60 in the rain….but I drove it for almost a decade first. Now I drive my mom’s old Acura TSX much more responsibly too.

Getting old REALLY sucks when you break yourself while you’re young! Oof!

It looks like we're all Bay Area refugees!

My Camaro was a shark-nose '97.

For classics, I owned a '73 Charger SE and I loved me the hell out of that car, too. It was the size of an aircraft carrier and the engine compartment was bigger than my condo. The scariest thing about that car was how easily the back end would come around in a sharp turn. The first rains of the year were a horror show when the pavement was like oiled glass. "Am I gonna beat that red? Gun it! ... uh-oh."

Now I drive a Mazda 3 and responsibly. Getting old sucks.

Arresting Cable Snaps During E-2 Landing - USS Eisenhower

oritteropo says...

The pilots interviewed afterwards:



As for what happened, H/T to Ohforfoxache from LiveLeak for the following:

What went wrong
The one-inch wire ropes laid out across a carrier's flight deck — known as cross deck pendants — are programmed to release a set amount of cable as the aircraft's tail hook drags them behind the plane, to absorb the force of a landing before spooling back up.
Below deck, a purchase cable is attached to each side of the deck pendant to absorb the force of the landing plane, controlled by an arresting gear engine.
On March 18, the engine was miscalibrated and couldn't absorb the energy caused by the landing, which transferred the load to the deck pendant, snapping the left side and sending it whipping across the flight deck.

Real Time - Dr. Michael Mann on Climate Change

Asmo says...

The inference being that I have a choice..? =) We don't in Aus.

But you're missing the point, X >= 1 feed in tariffs are being subsidised by other users on the grid. You upload your power regardless of demand peaks (so you could be sending power when it really isn't required). Electricity companies are not going to massively drop production of regular power as it takes a considerable amount of time to spool up/down baseload production, and they are still going to switch on high cost gas turbines during peak load just in case a big old cloud blocks out the sun for an hour or so and solar production falls in a heap...

And peak usage times are usually ~8-9am (schools and business start up, switch computers and air con on etc) before solar production really kicks in, and later in the afternoon when it get's hotter, people are getting ready for dinner. If you have significant daylight savings time shifts, then you can certainly get better production when peak demand in the early evening is occurring. If the panels are facing west rather than east or north (because that's where you maximise production and make the most money... =)

As for "the idea that it might take more energy to produce a panel than it will produce itself is ridiculous", I didn't say that it did, just that it's return on that energy invested is comparatively poor. You coal analogy is patently wrong though. Depending on which source you go to, coal is anywhere from 30:1 to 50:1 for EROEI (energy returned on energy invested). It's cheap to obtain, burn and dispose of the waste, despite being toxic/radioactive.

eg. http://bravenewclimate.com/2014/08/22/catch-22-of-energy-storage/

When you talk about solar PV and the energy required to make it, you're not just talking about the production line, you're talking mining the silicon, purifying, the wasted wafers which aren't up to snuff, the cost of the workers and the power that goes in to building, transporting etc, lifetime maintenance, loss of production over time and disposal. The above link puts PV at the low 1.5-3:1 which is well beneath the roughly 7:1 required to sustain our modern society (and does not cover the massive increases in energy demand and consumption from developing countries). And as the author of the article notes, these are unbuffered values. If you add buffering to load shift, the sums get even worse.

"Put simply, if solar PV is such a bad deal, how are they saving me so much money even without any rebates?"

I didn't say solar was a bad deal, I said it's a poor way to reduce carbon pollution. If the electricity company you are connected to is willing to pay high feed in tariffs to you and you save cash, that's great, but that doesn't automagically (intentional typo mean that solar PV is making any sort of serious inroads in to reducing carbon pollution.

If we're going to fix man made climate change, we need to be prepared to pay a far higher cost and worry less about our hip pockets. Nuke might not be economically viable without causing jumps in bills, but in terms of the energy output it provides over it's life time, it is one of the highest returns in energy for the energy invested in building it, paired with very low carbon emissions.

Obviously, the figures on EROEI depend on which article you read, as it's a very complex number to work out (and will always be an approximation), but it's fairly commonly acknowledged by people who do not have a vested interest in solar PV (vs low carbon power sources in general) that PV is a feel good technology that doesn't actually do a hell of a lot in terms of carbon reduction.

muscle car is so powerful it wrecks itself

newtboy says...

My motorhead's guess, no differential but instead a spool in the rear and still turning while adding power caused differing loads in the rear tires, causing a terrible wobble as the tires fought each other (and the suspension), ending by ripping out the rear suspension.
EDIT: That's why I use a Detroit locker in my Jeep, it's a spool when you add power, and a differential when you let off power.

So mechanically what happened? Differential failure?

Carbon fibre braiding machine

Sagemind says...

And for what purpose? Are they making really strong socks?
That's an awfully wide/hollow braid.
And from the design of the machine, they couldn't make it very long as that bar is pulling outwards, it couldn't go out forever, a meter or two at the most. (Not to mention the small spools.)

Transforming Formula One: 2014 Rules Explained by Red Bull

oritteropo says...

If there is a button the the steering wheel that gives an extra 100hp for overtaking by whatever method, I'm willing to call it push to pass. I expect that hitting the button would switch the engine to a high power torque mapping, use the MGU-H to spool up the turbo faster, and give a MGU-K boost exactly like last year's KERS button. I would also expect that not every team uses a steering wheel button for this function, but if Williams called it "push to pass" over the radio, I expect that they do. You could also have a separate engine mapping to do the same thing, and I expect that probably some teams do.

The RBR infringement was a bit more complicated than that. The FIA sensor was giving them inaccurate readings (it was reading high), and the FIA told them to apply an offset to the sensor values. They chose to use another method to ensure they weren't exceeding the 100kg/hr limit, and were excluded on the grounds that they had not sought permission from the FIA to do so and that it is not within their discretion to run a different fuel flow measurement method without the permission of the FIA.

I expect their appeal will be on the grounds that they did not in fact exceed the limit, and gained no advantage from their actions... and despite Christian Horner's level of confidence it could go either way. The last report I heard was that although they have lodged their intention to appeal, they have not yet actually tabled the appeal (but have a few more hours to do so).

Actually Mercedes were warned about the same issue. They chose to turn down their engines a bit to avoid the problem.

Formula one has been about getting around the rules at least since the 80s, and RBR have been very good at it. The camera mounting is very much in the category of satisfies the letter of the law, but very much goes against the spirit. I like the approach of using the camera mount as an extra wing actually (is it only the one team who did this?).

What they meant by this is to use all power available. They got 100l of fuel to go full 1½h race. The fuel flow is limited to 100l/h. That means they need to use around 67l/h on average, this of course decreases during braking and is almost at max during acceleration. Also energy recovery and the release of that energy has some leeway to be used in different ratios, it is limited to 33s per lap. How that energy is divided, is up to the team.. So they will have the full boost of 160hp from ERS and full 100l/h fuel flow when using "push to pass" button but it's nowhere near the common definition of that function. Traditional push to pass is high boost, on 2014 F1 it means few percentages of power. The correct term would be "overtake mode".

RBR infringed fuel flow rule and no other team had been even warned, FIA has guidelines that teams should calibrate with enough margins to void minor differences between sensors. RBR refused to do this and counted on FIA not counting that marginal change. FIA had stated pre-season that in no case there will be extra fuel flow allowed, it's almost zero tolerance policy.

They've done this before, made a marginal rule infringement and got away with Charlie Whitings slap on the wrist:"change it to the next race".. Their camera mountings is already one of those little things that is technically legal and at the same is not.. It all depends if the TV crews can find a suitable camera. If they say "no", the rules are clear: they need unobstructed view.. That small hole hardly allow high quality picture, the only lens that could even remotely suffice is fisheye lens with a mask: it is not their standard equipment.. RBR most likely will have to change those too (imho, so should merc camera pods and mclaren parachutes too). Compare that to Williams 360 camera pod and it's pretty clear what FIA means by "enough room to fit camera" means.

Last year they had holes on the floor in monaco: ruling was, change them to the next race.. Then there was the TC scandal, RBR used illegal engine mappings.. They used them last year too when there was a ban of feeding fuel to exhaust during zero throttle to feed the blown diffuser: RBR chuckled and used them anyway.. They still have the duct inside the nose, it violates the intention of the rule but is legal technically. Of course the severity of the punishment is a clear sign: FIA just showed that no more of that bullshit, RBR has to start respecting rules.

Huge ship ALMOST hits bridge in the Panama Canal

grinter says...

Hmmm.. Google suggests that the "Pacific Bless" is a cargo ship... it does have a lot of cranes on it. Either way, a wreck would have sucked.
Also note: That loud clattering in the video is the anchor chains spooling out. The smoke you see at the front of the ship is coming off of the anchor winches.

Intense new video of the Reno Air Show crash

GeeSussFreeK says...

@papple hehehe, trying to use reason to reason with unreasonable fears hasn't panned out for me. I can tell you the exact statistics on the death rates of commercial air flight, but it doesn't clam the panic any less when I hear those engines spool up.

Say no to drugs ! be a part of the CHICKEN club !
