I think before the big bang, you had a sphere of all matter in the universe, or 1U of matter, and the density built heat through gravity and friction, and it exploded into what we have now.Mikey_s wrote:Chris,
it is entirely possible that there are some exceptions to the laws of thermodynamics and, indeed, some of our general rules start to break down at the sub-atomic level. However, one of the things that gives us confidence that they are more or less correct is the universe itself; which is obeying the laws of thermodynamics as we speak; it is cooling down (evening out the temperature) and becoming less ordered, thereby obeying the conservation of energy and increase in entropy. Of course, just prior to the big bang it was probably not obeying the laws, but pretty soon after a few microseconds) it started to do just as one would predict - and, as the universe didn't exist prior to the big bang, it's probably academic to consider whether the laws applied then in any case .
Meanwhile, back in the real world there is a vanishingly small probability that we will manage to get even close to perpetual motion... but I'm not sure that we need to; there is plenty of energy pouring into our planet from the sun - it isn't really renewable, but for the purposes of our likely time as human beings on the planet we can consider it so. We can also use other (non renewable, but pretty long lasting) sources of energy such as tidal power from the moon's gravitational pull.... or less polluting sources of energy such as nuclear. However, until someone can provide one example of where the laws of thermodynamics don't work in a practical sense I think we can accept them as being applicable to the planet in general and Formula 1 in particular.
For the record, I'm not wedded to fossil fuels, nor anti-progress; I'm wide open to new technologies and astonished that the internal combustion engine is still so revered by car makers... it's hopelessly inefficient from the thermal energy perspective, it also brings to mind a saying I particularly like; you can polish a turd, but even when you've finished it's still a turd! Some internal combustion engines are things of beauty, but they ain't efficient...
As the old joke goes about the village idiot giving some directions to a fellow who was lost; "in fact the best way to get to your destination is not to start from here!" - never a truer word spoken in my opinion (and perhaps the village idiot wasn't such an idiot!).
Yes, the FIA are allowing 200kW systems in 2011, along with whatever the new engine regulations will be.Carlos wrote:From my local paper:

"The British-built flybrids which will be used in F1 develop 80 horsepower from a five-kg (11-lb) wheel which measures 20 cm in diameter (7.9 inches) by 10 cm wide (3.9 inches).
The F1 units, which weigh only 44 lbs (20 kg) in total, are capable of storing up to 400 kilojoules of energy per lap, releasing it in quick bursts that can boost acceleration for up to seven seconds at a time to aid passing.
Not yet convinced that flybrids have a future? Consider this: they weigh half as much as an electric hybrid system, take up half the space, are twice as efficient and cost 75 per cent less. And there is no battery memory to worry about.
The F1 flybrids are being built by U.K. transmission maker Torotrak Plc, which calls its system KERS, for kinetic energy recovery system. They're also working on a 268-horsepower system for the 2011 F1 season."
268 HP flywheel KERS in 2011? Anyone else read anything about this?
Still, a very good vid!WhiteBlue wrote:The are some fundamental problems to hydraulic KERS. One is the relatively low efficiency of rotary pumps and motors. Second is the high weight of incompressible fluids. And third is the big space requirement of hydraulic accumulators and their akward form factor. All of this is less relvant when you come to heavy commercial vehicles but it seriously impacts on road cars and racing cars. So I do not see this resolved in a short period of time. We discussed this when Ciro presented the hydristor. I hav not heard about progress of this device for the last year.
It [KERS] can be quite a strategic advantage. There are a number of tracks when the gain at the start could be two or three car lengths between a car with KERS and a car without KERS.
Some tracks will provide no benefit because they don't have long enough straights before the first corner, but there are a number of tracks where KERS will be very relevant for the start, and could mean two or three car places."
The MLC technology .... incorporates the permanent magnets of the integral motor/generator into the composite structure of the flywheel itself by mixing magnetic powder into the resin matrix.
