Stalwart hatchback gets a plug-in: Volkswagen e-Golf

spider from mars

compared to the BMW i3

Roughly the same price point, give or take a couple of grand, and the i3 has a range-extender version. Makes the Golf a bit of a hard sell.

Japan makes Prius palatable with road map to hydrogen cars

spider from mars
Thumb Down

Oh dear

Time for the standard fuel cell rant.

The problem is FCV's horrible grid-to-wheel efficiency.

Compared to a BEV, which just needs to account for grid distribution and the round-trip efficiency of the battery, the losses incurred by producing the hydrogen, compressing (or liquefying) it, distribution, and storage all result in FCVs using between 3-5x as much electricity as a comparable BEV - hence 3-5x the CO2 emissions (given the same energy generation mix - in fact it would be even worse because clean energy sources are currently a limited resource).

And that assumes you're getting your hydrogen from electrolysis. Commercial hydrogen is produced from natural gas, releasing CO2 in the process. If you run the numbers on this, it can be shown that FCVs emit more carbon than a traditional ICE car.

'Disruptive innovation' is nonsense? Not ALWAYS, actually

spider from mars

The article's not about Google's cars, though; I would be perfectly happy with an article predicting whether they will succeed or not.

The problem is that the author is trying to use his prediction as evidence, to make a wider point about innovation.

I think it would be prudent to wait and see if Google's car succeeds or fails before you use it as the central plank of your thesis..

Japan plans SEVEN satellite launches to supercharge GPS

spider from mars

Re: Is there a rocket scientist in the house?

@Imsimil Berati-Lahn

This is my guess too. Four satellites in elliptical geosynchronous orbits, tracing out the same analemma over Japan, so one of them is always at or near zenith.

Address confusion

If you've ever tried to find a building by its street address in Japan, you'll know why everyone has GPS on their phone.

There are no street names - instead each block has a number, and each house on that block. Except that the numbers are not sequential. With just an address it can be nigh impossible to find somewhere in an unfamiliar area, short of just wandering around and hoping.

Re: Bitcoin is strongly deflationary

"Austrian economics is pretty much common sense when you think about it,"

There's your problem. "Common sense" is not a reliable guide to the functioning of complex systems.

Bitcoin is strongly deflationary

Dabbs touches on this briefly at the end of the article, but this is really the biggest problem with Bitcoin qua currency - even accounting for its vast impracticality.

Simply because it's based on a limited commodity, Bitcoin is strongly deflationary. It's like the gold standard of the turn of the 20th century - there's a reason we invented fiat currency! It's no coincidence that Bitcoin appeals to the same Austrian-economics right wing libertarian cretins as a return to the gold standard.

But I digress. Those of us that grew up in the 70s (or Germans who are permanently terrified of a return to Weimar economics - i.e. the paymasters of the ECB) are taught that inflation is a axiomatically bad thing. This is, of course, bollocks. Moderate inflation is a good thing - there's an argument that our inflation targets should be closer to 4%, not the 2% we have now.

Deflation is crippling - just ask Japan. During deflation, the best thing you can do with your money is sit on it. Investment and spending collapses, and your country enters a prolonged depression.

And if we think we have trouble with an oligarchic elite now, the problem would be so much worse without inflation there to erode inherited wealth.

In short, Bitcoin economics is awful on every level. It's almost as if it has been designed to undermine the ability of governments to control the supply of money and to heighten the power of entrenched wealth (and let's not forget all that lovely potential for tax evasion). And we, the techies, blindly buy into this agenda because it's shiny and new, and has "crypto" in the name, and we think being free from government influence is great when actually it's the only thing keeping the plutocratic wolves from the door.

Re: whack-a-mole

nice try, but no. There's a difference between cutting down the parameter space of a theory and testing the theory itself: there's no falsification going on; we're not approaching the "truth" in any meaningful sense.

Eh, chasing SUSY is like playing whack-a-mole. The parameter space is so vast that for every bit you rule out, the theorists can just move their models to a higher energy scale.

Actually

"It's one of the "difficult" bits of relativity: even if you and I are travelling in opposite directions at 55 percent of the speed of light, the sum is 100 percent, not 110 percent"

actually, .55c +.55c = .84c

Re: £6.99 ?

apple's mail client handles gmail very badly - doesn't do conversations or labels properly - both of which I can't manage my email without.

I'm pretty gutted by this, as it likely nixes the upcoming Sparrow ipad app.

Well to wheel efficiency

the well to wheel efficiency of an EV is something between 1.5 to 2x that of a petrol car. Even accounting for 20% losses, you still come out on top.

Dropbox - mainly because I've got it already

And it's already integrated with a bunch of my other apps. (PDF reader, Browser for downloading files, Flashcard app, etc.)

Saying that, I rarely if ever use the actual Dropbox *app*, partly because the bundled reader is so bad.

Absinthe 2 lifts iOS 5.1.1 gadgets over garden wall

spider from mars

Re: Absinthe makes the farts blow longer

Apparently the BigBoss repro is being hammered and keep timing out. if you keep refreshing it'll download the packages eventually. My iPad required a factory reset the first time as well, but was fine second time round.

favourite JB tweaks:

- Springtomize: allows you to make a lot of little changes to the UI, hide undeletable app icons etc.

- browserchanger: change the default browser from Safari to whatever you want (Grazing, in my case)

- manual correct: no more DYAC!

- cardswitcher: new UI for app switching

- swipeselection: can move the cursor by swiping the keyboard. SO much easier than trying to tap between the right letters

- Retinapad: makes iphone apps look nice when zoomed.

- sparrow+: makes sparrow the default email client and enables push.
