During the interview it's mentioned several times that this should be more efficient than a conventional CVT. Conventional CVTs are already more efficient than automatic or even standard transmissions as they IC engine can be run at its most efficient RPM given the load, and even run at a more efficient cycle. I look forward to seeing it implemented in consumer automobiles, some time in the 2030's.

The Prius that was in the news recently, here in San Diego, the conventional brakes were useless, and shifting to neutral wouldn't work, as it wouldn't allow it. What was successful, according to the CHP, was a very zealous tug on the hand brake (definitely an "emergency" brake in this case) as well as the foot pedal. The officer positioned his car in front, not to slow it down, but to prevent it from shooting forward after the driver finally got the car to a stop, despite it still wanting to move forward. Essentially the squad car was acting as a brick wall, but not a brake assist.

In this case, the car would not shift into neutral, nor did foot braking alone make a difference. It was muscle on the hand brake that ever so slowly dropped the speed.

You are correct about the first casualty. It was a Lexus and it happened in Santee, CA (part of San Diego County). The brake and neutral attempt were useless. The situation is described thus:

---
California Highway Patrol Officer Mark Saylor, 45, his wife, Cleofe, 45, their daughter Mahala, 13, and Cleofe's brother Chris Lastrella, 39, were traveling on a freeway near Santee on Aug. 28 when their vehicle reached speeds of more than 120 mph, hit a sport utility vehicle, launched off an embankment, rolled several times and burst into flames.

Investigators found that a wrong-sized floor mat that trapped the accelerator was the cause of the crash. (Note, this has not been forensically proven, and is in dispute at the moment.)

A haunting 911 call captured Lastrella telling the others to pray before the car launched off the embankment.

...the Lexus ES350 "began to accelerate on its own." Saylor attempted to apply the brakes and do everything possible to stop the car, but he was unable to do so...
---

The video demonstrated the "technique" on a relatively low horse power (and low torque) four cylinder engine. A Lexus ES350 has a 272HP V6 (at full throttle) and the Prius has a high torque electric motor. Good luck with that braking.

What this article fails to include are the unique issues with the hybrid cars. Oddly enough, two have gone out of control in my home city, San Diego. The first being a death, which started the publicity. This one was driven by an off duty cop! I would think his training would have given him these skills to stop the car. However, as more and more facts have come out, the brakes it seems are useless. The Prius uses a combination of electrical and mechanical braking. Unfortunately the mechanical only kicks in under a certain speed.
Many people have reported burying the brake pedal to the floor and it having little effect. They also seem to not be able to shift into neutral, as it's a drive by wire system. Many cars don't let you shut off the engine if it's in gear too.
The Prius, while being a butt ugly eye sore and gutless wonder, also has an electric motor. These have 100% of their torque at any RPM. This means a gas engine can be fought and stalled with functional brakes, but you fight the full torgue of an electric motor all the way down to stopping, if you're lucky.
No, a fail-safe override needs to be considered for all drive by wire vehicles. Something that actually physically disconnects power from the system as a last resort.

My understanding is that the car driven by the off duty officer was a 2009 Lexus ES 350. That is not a hybrid. That said, I tried the 'move the shift to neutral' trick yesterday in my Windstar and it worked just fine.
However, the link I provided also noted: Last month, Consumer Reports found that models that don't have so-called smart-throttle technology, which allows the brake to take precedence over the throttle, a vehicle might not have adequate brakes to overcome a stuck throttle at 60 mph.
So, jam your foot down on the brake and kick it into neutral, pray like hell that you hit a truckload of Snuggies.
As for the electric cars, maybe a nuclear air burst that issues an effective electromagnetic pulse would do the trick.

Exactly, at her fastest she was moving at 308 rpm

so he had the car in park? break pedal down with the parking break engaged? Did he think his car had line locks or maybe that to peel out one had to hold the breaks down first to get the RPMs up? Maybe a front wheel drive car that was lowered too low and the wheels were stuck in the wells? In the end, you can't question stupidity.

what ...the....FUCK did i just watch?
this video had me mouthing off like don rickles on a crystal meth bender but i'll curb my urge to eviscerate this....*cough*.....music?
talent aside...and lets be up front..these guys have some talent but the whole "arpeggio/melodic/overload with lyrical operatic overtones" was already done by jason becker and marty friedman in the 80's.if you like these guys you will most likely enjoy CACOPHONY.
i'll upvote on the bizzar factor but not on content.this song is...yeesh.../cringes.
meh../shrugs..maybe its just me but it seems they should be played at 33 RPM's and not 44 RPM's.
and i am by no means a purists,my music tastes are extremely eclectic but i'll listen to death metal before being subjected to this.
sorry guitarwolf but i cant join ya in appreciating this band.
seems you really like them.

I think there's a pretty clear and obvious reason why "where no one has gone before" describes this gizmo. You'd be hard put to find a less efficient method of propulsion, which implies that you need to have an incredibly overpowered motor and prop to get anywhere (as he found out).

RC props turn at ungodly speeds (11-20K rpm), and I just don't see how you could possibly use one that close to your body in a safe manner. On a plane, they'll literally shred anything resembling flesh, and there's just no way that flimsy little wire cage is going to be any protection when a blade breaks for any reason.

Why did the technology die with him? Surely more could be built?


One person with extraordinary vision, coupled with technological know-how, engineering brilliance and the ability to get his hands dirty and plain-and-simple build what he imagines is a rare thing.

In the case of the Britten bike, this is a partial list of what made his bike special:

1) Partial girder-link front suspension with adjustable anti-dive properties.
-fork-type suspensions compress under braking and extend during acceleration, changing the geometry and handling characteristics of the machine quite drastically during the different driving modes. Britten's suspension design allowed him to control pretty much all variables of suspension geometry under changing load, making the bike behave however the rider wished.
- The rear suspension, while perhaps not as revolutionary, was a beautiful piece. It was essentially a carbon-fibre banana swing-arm with a linkage to the adjustable shock/spring assembly. If you look at the bike you'll see that there's no spring/shock assembly near the rear suspension, rather note the spring/shock assembly directly behind the front wheel- this is for the rear suspension! The front shock assembly is hidden in the front suspension linkage and cowling.

2) The engine itself was a stressed-member.
-While certainly not unheard of, Britten took the concept to an extreme, essentially eliminating the frame from the motorcycle. The front and rear suspensions essentially bolted directly to the engine, thus saving many kilos over contemporary designs. Take a look at any current MotoGP or Superbike- most use the engine as a partial stressed-member, but they all have frame members linking the engine, steering heads and seat-assemblies. Britten really only had a vestigial sub-frame for the rider's seat.

3) Well-controlled aerodynamics and fully-ducted cooling system
-Britten paid close attention to airflow over, around and through his bike. Look how cleanly the rider's body tucks into the bodywork. He paid close attention to details, notice how clean the entire assembly is- no exposed wiring, nothing dangling into the airflow, that incredibly sleek rear swing-arm and rear tire hugger. This keeps the airflow smooth and un-disturbed. Motorcycles aren't terribly aerodynamic machines in the first place, but a wise man once said God is in the details.
-The engine itself is a water cooled design, but where's the radiator? It's in a fully-sealed duct directly beneath the rider's seat. High-pressure air is inlet from the front of the bike, through the radiator and is exhausted into the low pressure area beneath the rider and above/ahead of the rear wheel. Greater cooling equals higher power potential.

4) The motor
- 999cc 60 degree V-Twin, belt-driven DOHC design, twin injectors per cylinder, sophisticated electronic ignition, hand-made carbon fibre velocity stacks, wet sump. The motor was designed to breathe hard, pumping out torque and horsepower (166 hp @ 11800 rpm- not sure about the torque figures), and run cool and reliably under racing conditions. Nothing here that any other manufacturer couldn't have figured out on their own, but Britten had the insight and the will to make the best motor in the world at the time. The 60 degree configuration was, I assume chosen for packaging reasons. Normally this configuration would have bad primary balance characteristics, but Britten engineered his to such tight tolerances that the engine ran smoothly right up to redline (12500 rpm) without using a balance shaft.
I'll also point out here that Britten wasn't above using someone else's part if it was better than he could make himself- the gearbox was from a Suzuki superbike, and the cylinder liners and voltage regulator (both of which failed at the Daytona race in '92- the latter costing Britten the win) were from Ducati.

5) Carbon Fibre
- While Carbon Fibre had been around for 2 decades or so at this point, nobody had used it so extensively. Britten used the material for bodywork, wheels, engine parts, suspension girders and the rear swing-arm. There is still no other bike, not even the current Ducati Desmosedici MotoGP bike, that uses so much of this exotic material. The stuff then, as it is now, was hugely expensive and challenging to engineer for different applications. Britten made everything himself, in his garage, figuring it out as he went. This kept the total weight of the bike to a hugely impressive 138 kg.

Keep in mind that he did all of the above in 1991 and 1992, with the help of several neighbors and one part-time machinist, in his backyard shed! He made the bodywork by hand, using a wire frame and hot melt glue, crafting the wind-cheating shape and cooling ducting purely by eye. He cast the aluminum engine parts himself, heat-treating them in his wife's pottery kiln, and cooling the heat-treated parts with water from his swimming pool!

Ducati, Honda, Kawasaki, Suzuki... any one of these manufactures could today reproduce and expand on what Britten accomplished almost single-handedly. None of them will- there's too much at stake for them. It's far safer to stick with the tried-and-true, making small evolutionary changes over the years. A true visionary achiever (to coin a term) like Britten comes along only every once in a great while.

I suppose that this is what was really lost when John Britten died... vision, engineering acuity, hands-on knowledge, and pure will. Touched with a little craziness.

small blades require much higher rpm and noise. and normal fans also "multiply the air" by creating negative pressure behind the fan.

i'm sure it would be safer than a normal fan if fan injuries were common but they aren't.

i don't really see a purpose for this device

Oh, now I remember!

This machine was created by artist/engineer Arthur Ganson. It consists of a 200 rpm motor turning a series of 12 gears, each with a 50:1 reduction. The implications of this are that the final gear will make a complete revolution in approximately 2 TRILLION years. Another implication is that a force of 1 lb/ft of torque input will result in a monumentally staggering 244 QUINTILLION lb/ft of force or 244 billion billion! The final drive is formed into a solid concrete block- which will surely shater from the staggering forces generated in a few hundred billion years, if the universe hasn't ceased to exist by that point.

Keep in mind that the age of the universe itself is estimated at 13.5- 14 Billion years, and the mass of the known universe is estimated at 38*10^49 metric tons. In other words, you would have to wait several dozen lifetimes of the universe for one complete revolution, and while you wouldn't be able to move the whole universe with this machine, a few galaxies wouldn't be out of the question!

Edit: Another thought I've had regarding this remarkable machine is the amount of horsepower being generated- effectively zero as there is no work being done in time-periods would normally be used for calculations. Give me a lever long enough...

And he does it without wearing safety glasses.

The bandsaw goes at lower RPM than a circular saw so it's less likely to send chips flying and also less likely to kick the work back at you. Bandsaws rock.

If he could just crank it up another few RPM, he could travel back in time.

Grinter is right, EDD is not.

F1 cars are capable of going straight slowly without spinning; otherwise this would happen to everyone at the start of every race, when they first start.

Most likely he mis-timed the shift. It's like when you are driving a normal car aggressively, and you dump the clutch at an RPM that's slightly too high, the tires will chirp. This can happen even if you're already moving, and just shifting to 2nd or 3rd gear. In a normal car it's not too bad, but when you have that high a power to weight ratio the rear end just snaps loose from the road and goes where it wants to.

Ever since they took traction control off the F1 cars, even the pros do this sometimes. Usually they're exiting a corner when they do it, but it's happened on a straight too.
