Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

N Monkey Re:Charging amperage (395 comments)

Charge car battery up to 70% in 2 minutes? Dare you calculate the amperage needed? Somewhere in the ballpark of 10000A in 12V? That would do it, melting all wires in the connection.

You're thinking of standard lead-acid car batteries for ICEs.

Charging stations operate at "slightly" higher voltages: See Charge point basics for details on European ones.

EG, of the faster AC ones, ~40kW, for example, use 3-phase power at around (_IIRC_) 450V.

Mathematicians Solve the Topological Mystery Behind the "Brazuca" Soccer Ball

N Monkey Re:And another question (144 comments)

Yeah, wow, I didn't realize that form was so relatively recent. I had thought that's what soccer balls were "always" like. (From the Wikipedia page, they actually came out before 1970..)

They probably started as nothing more than an inflated animal bladder, but I do recall seeing one of these http://comeheretome.files.word...

Walmart Unveils Turbine-Powered WAVE Concept Truck

N Monkey Re:Why so many trucks? Why not railroads (242 comments)

No the reason is that trucks don't pay fairly for the road wear while train's have to pay for rail wear. Do you think any politicians would dare try to enforce a tax based on vehicle weight. Nor do they pay for the new roads which are built for passenger cars...

Given that road damage is apparently proportional to the 4th power of axle weight (too lazy to put in link to wikipedia), it seems unlikely anyone would be brave enough to push that legislation... but it'd make railways more attractive.

FLOSS Codecs Emerge Victorious In Wikimedia Vote

N Monkey Re:Why does Wikimedia hate batteries? (235 comments)

The hit isn't a very big one:

"with the hardware offload the battery lasted up to 36% longer"

http://blog.webmproject.org/20...

And with each faster processor generation, the difference gets smaller and smaller still.

Followed the link but couldn't see where it showed actual power consumption of the hardware decoder they used (their own I guess?) but given that an ARM CPU might consume around 500mW whereas an H.264 hardware decoder doing HD uses 10mW, either the screen is using a huge amount of power or their hardware leaves a bit to be desired.

The Man Who Created the Pencil Eraser and How Patents Have Changed

N Monkey Re:Independence of the courts ? (234 comments)

If you found a way to make a fan that blows air out of potato chips, in principle that would not be patentable, because you just "stuck together" two existing things; fans and potato chips. It doesn't do anything novel.

Funny you should mention fans given Dyson's recent innovations. Dyson had to massage the wording of the patent quite massively to get their patent for the Air-Multiplier fan, not surprising given how it was invented by Toshiba in the 80s

"Massaging"?? Having just read that news report, it seems they just needed to include other inventive features of the design in the patent, which probably just means the claims had to be 'narrowed' to include that feature.

I don't see any issue with that. There is nothing wrong with patenting an improvement to an existing invention as long as it's non-trivial.

What's Causing the Rise In Obesity? Everything.

N Monkey But they don't use less... (926 comments)

table sugar: 50% sucrose, 50% fructose
HFCS: 45% sucrose, 55% fructose
It's not really a big deal. Yes, you'll increase your fructose intake 10% if you eat the same quantity as "sugar", but HFCS tends to be considerably sweeter, so you'll probably be using less and at least partially offset the difference.

Can't remember the name of the documentary I watched but it reported that, despite it being sweeter than standard sugar, the big drinks companies put far more HFCS into their products than they need to.

UnGrounded: British Airways Attempts to Bottle Some Startup Spirit

N Monkey Re:Free publicity (128 comments)

This is about as useful as tits on a bull.

Though it'd make the bull more attractive.....

Being pedantic, it should really be interpreted as

      "as useful as the tits on a bull".

i.e. they may be there, but do b_gger all.... ...... although YMMV :-)

German Railways To Test Anti-Graffiti Drones

N Monkey Re:Techy drone-boners must stop. (208 comments)

Graffiti is a huge problem in Germany. All the graffiti is really embarrassing when I'm in Berlin with people from abroad.

Not train related, but on a visit to Koln I was saddened to see the amount of graffiti covering the cathedral.

Cause of LED Efficiency Droop Finally Revealed

N Monkey Re:Answer not in summary (308 comments)

So, you're saying that instead of an electron falling into a hole causing a photon to be given off, the electrons are all huddled together elsewhere talking about the last episode of Big Bang Theory?

No. They'd be discussing "Quantum Leap"

Six Retailers Announce Recall of Buckyballs and Buckycubes

N Monkey Re: Seriously? (343 comments)

Did you miss that if you eat them all at once, they will stick together in one clump and therefore none would be in an "adjacent track of intestine". Although, I would think that just having a, effectively solid, chunk of indigestible material the size of several buckyballs may be a problem in of itself.

Not if you test first like the monkey ;-)

How are they going to store the data?

They'll use the "Cloud".

..., Oh, wait...

No problems. Plenty of those in the UK.

Israeli Firm Makes Kilomile Claims For Electric Car Battery Tech

N Monkey Re:SI vs. US customary? (247 comments)

I love the units used in the summary title. Kilomile? A better statement would be Megameter.

Kilomile = 1000 miles.
megametre = 1000 km.

Last I checked, a kilometre is much shorter than a mile...

And a kiloleague would be even longer ... but the point I assume the GP was making is that it seems stupid to use an SI prefix with an antiquated unit of measurement.

Australian Police Warn That Apple Maps Could Get Someone Killed

N Monkey Re:Apple bashing (452 comments)

Anywhere in Australia can be dangerous if you get stranded, because it's hot and dry.

... and animals that are trying to eat you everywhere, as far as I've heard.

Do you actually know what the most dangerous animal in Australia is, i.e., the one that kills the most humans? One that killed around 100 people in one year alone? You may be surprised.

How Patent Trolls Harm the Economy

N Monkey Re:First Post (123 comments)

Has the current Slashdot readership really become so retarded than unfunny jokes like this, repeated for the n-millionth time, are still getting modded up to +5?

How the mighty are fallen.

Are you suggesting that many of the slashdot moderators use similar criteria to judging novelty and inventiveness as ....?
