Motorola assembly programmers had the HCF (Halt and Catch Fire) commands for a decade prior to Intel's shitty knock-off that was a bug, whereas it was a FEATURE in the Moto chips!;-)
Yeah, what's the later life cycle of the abused electrical system of a hybrid going to be like to maintain? That'll be fun. Backyard mechanics and high current zaps.
Yeah, plug in at work. You haven't met my employer's HR manager, CatBert -- have you? These are people who keep redesigning the cubicle layout hoping for more productivity, when the easiest way to get me to do 2 more hours of work a day would be to let me avoid the 27 mile commute and do my job from home.
Most "memory" effects have been debunked for many years in systems designed to properly charge and discharge the batteries utilized.
Ask NASA how long some of the NiCd packs on-orbit have lasted.
Seriously -- most "memory" in consumer products isn't "memory" at all. It's over-charging by crappy cheap wall-worts, which leads to overheating and venting of gaseous electrolyte, from NiCd.
NiMH is more fussy about how it's charged, but most product's chargers cook those too.
LiPoly and similar can be unstable if charged wrong. They've almost always come with fancy charge controllers that take all the possible ways (other than storing them discharged which kills them fast) away from the end-user.
I have NiCD's here that I have taken care of properly, NOT using the factory chargers in many cases, and they've lasted a decade or more.
REALLY GOOD chargers and chipsets to handle charging all sorts of battery types are out there for manufactures, but they want to save a few bucks and just sell you an unregulated wall wort for charging they bought for less than a buck apiece from China.
When was the last time you saw someone in a real technical or consumer review FIND OUT how the charging circuit works? Shouldn't we demand such information?
The alternator puts out 100A @ 13.8 VDC, typically. NOMINAL voltage of an automotive system is 12 VDC. So bump that number. It also puts out that current only at some speed above idle, typically.
You then tried to use KwH as a transfer of power measurement, which won't work because you've left out all the charger efficiencies/inefficiencies.
Instead of trying to make this difficult, why not get the following information:
- You know you have a power source that's 13.8 VDC and capable of supplying roughly 100A continuously as needed.
What you need to know is from the electric car's manufacturer. How long to charge at that rate to go X miles. Their electrical engineers will know.
There are losses in the cabling, the charging circuit itself, etc. The raw power numbers don't matter without the engineering data on the rest of the charging system being used.
Actually it only helps "us" in future generations. If you have no plans to reproduce, consume all you like. If you have plans to replace yourselves with ankle-biters, then you can play the "What about the children?" game. And if you plan on more than replacing yourselves, you're the biggest problem of all.
Kinda like vegetarians getting to choose specific foods they want to eat, and often bother their friends with stories of how their lives are miraculously better (or whatever banter about food they might have) in a country where starvation is rarely a killer, and hunger is virtually unknown.
I'd like you to defend your "minimal environmental damage" statement at the very beginning. If you had a magic wand, and we were all driving electric cars tomorrow, what would the additional load be on the electric grid, and how much more pollution would that load cause when fed (mostly) by coal-fired power plants?
I contend that energy consumption is energy consumption, and moving everyone from hydrocarbon burning to burning coal isn't really fixing anything in the long-run.
People buying/doing shit they don't need to isn't a problem. If you're so worried about it, unplug your computers, stop wasting electricity posting on Slashdot. Rubber, meet road.
Since Chevron-Texaco was broken up by the SEC, and BP bought Texaco instead, I'm finding your facts weak enough that you'll need to do some homework and get it right before anyone will believe you.
Like wanting the "northern asses" to send FEMA and money to fix damage from a hurricane? Maybe those cops should think about that.
I don't see Missouri bitching on national TV for FEMA to fix everything after their floods. They just get out the heavy equipment and fix their own problems.
Please feel free to have kids, enjoy all the things you say they bring into your lives, and not take a discount on your taxes every year for having them.
With the world looking at ways to lower energy consumption, our industry is retarded if we're going to keep pushing to higher and higher CPU core numbers, higher and higher power consumption, etc.
Is this just the industry's way of giving up and realizing they can't get control of so-called "software engineers"?
Put some leashes on some people, measure PERFORMANCE of code again like we did when we didn't HAVE massive CPU horsepower, and actually work hard on sysadmin goals like properly prioritizing processes running on the hardware?
Think any of that would help a whole lot toward being able to close down a whole lot of data centers?
Won't happen though -- we're humans. We want it now, we want it fast, and we don't care if we have to leave a steaming pile of shit in someone's yard to accomplish it!
Create non-crappy code (even if you have to get underneath the compilers and high level languages to do it) that do the core things people need REALLY WELL perhaps, and say to hell with buying more and more cores from Intel?
I know it's a pipe-dream at this point. Multiple generations of coders haven't analyzed their code for speed/CPU efficience in almost two decades now. Those folks will never learn how, either. No business motivation to do so.
(Hint: Stop buying hardware and make people use what they have for a while, fall back off the leading edge and wait a bit. Those ideas/words scare Intel to death. They HAVE to sell you "more cores!" or "more GHz!" or "more MIPS!" every year to stay in business, now don't they?)
Ask him if he likes spam in his inbox, and arrange for some "extra" to arrive in a timely fashion.
If he continues to think it's a good idea, arrange for his Inbox to have a "spam filtering accident" that includes copies to his bosses of all the porn spam he gets.
Slashdot Mirror
You must be new here.
Ahh whippersnappers.

Yeah if you call a port-a-potty a toilet and a cot from WalMart a bed.
Yeah, what's the later life cycle of the abused electrical system of a hybrid going to be like to maintain? That'll be fun. Backyard mechanics and high current zaps.
Good lord... someone else here did pay attention in math class! Yay.
Yeah, plug in at work. You haven't met my employer's HR manager, CatBert -- have you?

When I first looked I thought you had typed X10.
Awesome head-typo during reading that was...

And how much energy is used, and CO2 is released, by Toshiba into the atmosphere when they make them?
We haven't built any NEW oil refineries in almost 40 years either.
Coincidence, or just good "maximization of profit" planning on the energy company's part?

There are still a lot of babies born in NYC and Bombay.

It won't be bankrupt. Those too lazy to save for retirement will make sure to tax the fuck out of those of us who do to "fix" it for them.
Show us your numbers. They don't lie. It's far more likely that you do.
Since Chevron-Texaco was broken up by the SEC, and BP bought Texaco instead, I'm finding your facts weak enough that you'll need to do some homework and get it right before anyone will believe you.
Ah yes, thanks.

Dear parent,
Please feel free to have kids, enjoy all the things you say they bring into your lives, and not take a discount on your taxes every year for having them.
