yes , its ok and will charge a battery when the whirleewhirlee breaks
the mains supply

 

Yeah but you can't create power so you can only ever get nearly the output
of the input.
Say you're burning 1000 watts energy in your internal combustion engine
you're maybe creating 500 watts of output power and 500 watts of heat and
noise.
The alternator then takes the 500 watts of energy and turns that into 200
watts of electrical power and the rest is turned into heat and (perhaps)
light.
So yes; your 25cc whippersnipper could probably run a 150 candle-power
lightbulb or similar.

 

Holy mother of god; get the women and children off the street!!

 

Hmmm [rechecks thread].... YES.
Air-con too!

 

I should've known 45kph was pushing into "Totally Ludicrous Speed"!

 

800 revs.

In the words of Bugs Bunny....

"I know this defies the laws of physics, but I never studied law."

 

I'd have thought that the doors being locked might be good if folk were
trying to pull occupants out of car, or, OTOH, bad... for the same reason.

Many years ago, in britain, it used to be illegal to drive a car with
the doors locked.

The logic was that if you stacked it, locked doors made it harder for
people to pull you out of the remains.

Bugga me! Being a simple lad, I thought they were just to make it
easier to get the end of the air hose connected.

Interesting thought, although many times in crashes where significant damage to the vehicle occurs, the doors cannot be opened
anyway, regardless of whether the doors were locked or not.

 

Maybe once, but we have very big can-openers nowadays...

Burst-proof (-resistant might be a better term) door locks are now
ubiquitous and do not impede a properly equipped rescue team.

Then again modern cars such as BMWs are very hard to get into, even for
Road Accident Rescue teams because of materials tougher than our tools
and pyrotechnic devices but the flip side is that you'd have to be
trying very, very, very hard to get hurt in one...

 

Aye, but, Joe Public doesn't have them, and Joe is the most likely
person to be first on the scene.

Agreed, but see above.

Some people put a serious amount of effort into it. :-|

In the past, I have been the first on scene.... four people in a _very_
twisted, mangled mess of a car, wrapped round a power pole... petrol
everywhere.

At the time it made sense to me to remove those that I could from what
seemed like a potential fire bomb. (My mate was sent off to get the
experts.)

In similar circumstances today, I'd really hate to just have to sit and
watch what happens because the doors are locked. <shrug>

Yes, you're right. Every prang is different, some doors, though mangled
can be easily opened, others may look undamaged but will be jammed into
bodywork.

A seatbelt cutter, like a fire extinguisher is a good investment and is
more likely to be used on someone else's car other than your own.

You'd be surprised at how quickly a hacksaw can cut through roof and
door pillars and frames...

All valid points, which reinforce my opinion that motorcycles are much
safer than cars, both for the occupants/riders and the things they might
run into...

 

Typical ! Ignores invite to attend drinks at North Sydney Hotel while
it was my local and 800metres stagger away, waits until I move back to
the inner west and NOW he wants to catch up ! Hmmpph !

(yeah all good, maybe it's time for some sort of ausmoto drinks or
sumthin' ? Maybe a ride ? Anyone interested ? Bueller, Bueller ?)

 

Ummm... As previously stated, I know little about electrics, but even
less about physics - I leave that up to the physicians - so I have no
idea what the **** you're going on about... but some others seemed to
agree with me.. so I my guesswork couldn't have been too far off the
mark.

I hope you're not suggesting that it will move, because that will blow
the original "uses more fuel" argument out of the water...

I know in new Commodores (and I presume other production cars as well),
whenever the airbags are deployed, the doors all automatically unlock,
and the interior light turns on.

In BMWs, the windows also drop two inches so the pressure increase
inside the car when the airbags deploy doesn't blow them (or your
eardrums) out, the battery leads sever themselves with a pyrotechnic
charge and the car calls BMW for help.

Also, If there's no passenger, the passenger side airbags don't deploy.

There's probably a few other things that I've forgotten as well.

 

Eh?

Paul is correct. Feel free to point out where he is wrong.

You go and "quantify" the "waste of petrol".

Thanks
