BEST BATTERY EVER: All lithium, all the time, plus a dash of carbon nano-stuff

WTF?

Vehicle range

You need around 100KWh for s decent car motive battery

I cant quite make the numbers add up, but at 3.8Ah per gram., that's (at a cell voltage of 3.7v) around 10Wh per gram or 10kWh per kg.

That is so far from actual battery weights that I simply don't believe it.

Wiki suggest lithium is less than 0.5Wh per gram

WEll what I do personally and what I suspect is happening in any company that values its data, is that as the kit changes, the old archive data gets pushed onto the new technology.

The OS is rubbish on GP desktops..most people there have gone BYOD anyway.

The OS is rubbish as industrial strength server. Most people have gone Linux.

...might as well get a train or a bus...

Well yes an that actually points to the way in which if you have to do transport without carbon based fuels, you go about it.

BEV from house to station, plug it in and get on electric train, fare including car at the far end.

Use the BEVs for the 'last 50 miles'

WE already have motorways built: convert them to train tracks.

Never watched Formula Ford or Ginetta racing? With less power overall the aero has to be reduced and that means slipstreaming becomes the way to get past... and it is a lot less processional than F1 can be.

Benefits from racing..

I can only half agree that its a waste of time.

What will filter through into road uses eventually will be batteries that can be fast charged and discharged, better energy recovery systems and ultimately better batteries.

Two things stand between now and widespread adoption of electric road cars, range and cost.

Range will always be a problem with BEVs as even the theoretical best energy density of lithium ion simply isn't good enough and lithium air is so early in the development stage its uncertain as to whether a safe cheap battery will ever be made using that technology.

Cost should come down as production engineering gets under way. Lithium is not expensive nor any of the materials involved and they are more or less recyclable. So te gig issue is range and how that can be extended by energy recovery and as good as it gets battery design and also by developments into faster charging.

Right now the majority of road trips are short and a BEV should make an ideal 'second car' for those that can organise off street charging. Overnight charging at 3KW levels - or more with an adapted circuit - is enough for about 100 miles/day or a potential 35,000 miles a year car.

Personally if a BEV was economic lifetime wise over a fuel car I'd get one for the shorter trips. The performance is JUST good enough for that: What holds me back is cost.

acceleration..

Actually peak power is not an issue with electric. Many model plane fliers are happy to flatten their batteries in 2 minutes flat to get astounding power to weight ratios and top speeds.

If you compare power train weights and power outputs fuel is about the same.

Energy density is the killer. Its simply carp (anag.) for batteries. Not power density.

Re: The ear can't hear square waves.

If you put a square wave through a suitably designed high order 20Khz LP Bessel filter it still looks square, just with sloping sides and a bit of corner rounding.

The point is that what is at stake here is how much we hear in the time domain and how much in the frequency.

My experience suggests both. 'Clicky' sounds abound in the environment, and the information content and especially the location is not just assessed by how the relative volume is affected, between ears but by time delay. Mess with that and it doesn't sound 'real' any more.

'Classical' music is relatively free of sharp transients: Rock music is full of them. If all you listen to is opera, go for low distortion labyrinth.

but stick to IB for Led Zeppelin.. ;-)

Thumb Down

Re: Actually, it's irrelevant for 90% of recorded music

Sadly this is in fact true. Well nearly.

I can think of three occasions on which I can say (I used to design Hifi and other audio gear) that I really understood what true HiFi was.

1/. Testing out radio 3 classical concert on the sort of speakers I could never afford, and hearing not 'applause' but individual people clapping. Clapping is exactly where the time domain is important. Otherwise its sounds like white noise.

2/. Listening to an album called 'Bass Culture' - probably the heaviest and most political reggae album ever made over a 2KW setup featuring 4x15" woofers in closed cabinets. I did manage to crack the studio ceiling. BUT every bass slap was a punch in the guts ..superb.

3/. Standing in the middle of a disco dance floor where we had rigged medium and HF horns to focus the sound exactly there, and actually pull the level down at least 30dB off floor where there was a restaurant. SPL up around 110DB with no distortion and it wasn't painful, just unbelievably clear treble with an amazing stereo image.

Yes, you can do good sound systems, but generally the cost is in 5 figures.

However, post processing does not murder the sound of hi hats and snare drums. Or an acoustic guitar.

Its worth while having the kit if you really can hear the difference. Most people cant.

Re: Ancient technology

I gave up designing audio amps when essentially they got to be about 100-1000 times more accurate than the speakers and microphones that drove/were driven by/ them.

Valves distort in interesting ways without needing to be designed to do that thing: With transistors if you want that sort of overdrive you need to design it specifically. Having done so, they sound like valves. Apart from the microphony that is. But you can add that in as well.

I'll endorse just about everything the author says in the article. Time delay on a bass reflex or transmission line makes a total mockery of a bass drum or bass guitar slap.

You need IB and a damned big one. Preferably Infinite :-)

Oddlly enough a wall of speakers with open backs approximates..

Re: One of these things is not the same as the other...

Umm. IIRC light can be refracted by gravitational masses, but neutrinos...what path do they take?

Well they have mass so should also be bent by strong gravitational fields en passant, but to the same extent?

My A-level physics gives up at this point.

Also light slows down when passing through matter, but neutrinos do not I believe?

Yes and no...

In the sense that I use the net. It does not use me.

And a lot of my USE of computers is not dependent on network access.

In the last 5 years since I have been primarily Linux, I have nit been caught by malware. Of any sort. I run no AV software.

Yes, several of my (potentially infinite) email addresses have been leaked by sites I have given them to, of course, so spam management is a daily chore.

But that's the full extent of the problem.

Re: unlikely

Yes. The whole thing is massively so unlikely as to almost guarantee that it was planned. The questions are of course, Why? By whom?

Of the two questions, the second is most easily answered. Occam's razor has to have it that the pilot or co-pilot did it.

The search is really to confirm that and eliminate as far as possible mechanical failure - and to provide closure for the relatives of those on board.

WE may never know why. It is and extraordinarily complex way to commit suicide...none of the tinfoil hat theories of geopolitical conspiracies make any sense either. I love a good tinfoil hat hypothesis as much as the next man, but there simply aren't any good ones in this case.
