Researchers Say Neanderthals Created Cave Art

K. S. Kyosuke *Old* cave art? (15 comments)

40 kya is pretty old, even as far as cave art is considered. But Neanderthals certainly didn't pain Lascaux - too recent for that.

New Computer Model Predicts Impact of Yellowstone Volcano Eruption

Are the officials buying gold, firearms, and agricultural land on other continents at an increased rate? If the answer is "yes", start doing the same as soon as possible!

What, even the voter turnout? Have you read what Putin's people had to say to it? Their estimate is that at most 30% of Crimeans threw in a "yes" vote, not the 80% of the "official" results.

Hidden Obstacles For Delivery Drones

Obama runs a baby-Stalin dictatorial regime.

Does the baby Stalin sport a magnificent mustache? If not, I demand a refund!

Hidden Obstacles For Delivery Drones

K. S. Kyosuke Re:What problem does this solve, again? (120 comments)

You could (and perhaps should) have self-driving road delivery drones. Those even may not have to be full-car-sized - lower material use, less fuel consumption, more flexibility, and still no driver. One would need a smart package dispenser, though.

Power Grids: The Huge Battery Market You Never Knew Existed

K. S. Kyosuke Re:Flywheel spin and political spin (164 comments)

It could, but they'd be stupid to use it for that purpose. Grid losses average 7%. You get that much loss out of the AC-DC then DC-AC conversion, and possibly many times more losses out of the charging/discharging cycle losses of any battery chemistry... Meanwhile, speeding-up/slowing-down a turbine has little or no loss.

I thought the turbines (or turbine-generators, more accurately) were generally synchronous? As in, you "speed up" if you're overdelivering steam into it, and "slow down" in the opposite case. Are there any large installations with complicated invertors or convertors within power plant facilities?

Power Grids: The Huge Battery Market You Never Knew Existed

K. S. Kyosuke Re:Flywheel spin and political spin (164 comments)

I'd actually expect a modern HVDC station (in the foreseeable future, at least) to work like an energy router. Especially considering that I expect these stations in the future to be designed with the ability to cope with the power characteristics of renewable energy sources in mind, i.e., they ought to be able to do some distributed load smoothing, which is going to require the grid to be able do to power flow reversals at least on the long distance and medium distance scale. The station hardware might be costlier, but hey, at least you shave off a few percent of transmission losses and get to transfer more power over the same power line cross section, so that might reduce the costs at least a bit. (And it may yet turn out that we simply won't have any other choice anyway.)

Power Grids: The Huge Battery Market You Never Knew Existed

K. S. Kyosuke Re:Energy storage systems that are stationary..... (164 comments)

What if you were working on batteries the size of a tractor trailer that had the energy density to power large cities for a week or two. Then you wouldn't need the grid. You could just drive the battery to where it could be charged, near the wind or sun, then when it was full, move it to the place where it was needed.

Those batteries are called nuclear fuel rods. I'm sorry, reaching "just" the hydrocarbon levels of fuel density in batteries would be a tremendous accomplishment that would probably allow us to get rid of a lot of our energy headaches, but there's no chance in hell that even a tractor-trailer-sized load of hydrocarbon fuel (or its equivalent) is going to be able to power a large city for a week (more like a few minutes or something).

K. S. Kyosuke Re:Never knew existed? (164 comments)

Likewise. Also, I'm personally in favor of doing more research in the capacitor department. This is a static application, not a mobile one, so bulkiness may often be of little concern but lifetime and low maintenance are.

Battle of the Heavy Lift Rockets

K. S. Kyosuke Re:Competition is good. (197 comments)

It's also completely useless, given that the inequality mentioned quite obviously refers to the time development of the function of wealth over population percentile brackets or how is that damned thing called in English.

Ukraine Asks Zuckerberg to Discipline Kremlin Facebook Bots

K. S. Kyosuke Re:Wait.... what? (227 comments)

So how about the overwhelming majority of the citizens choosing independence in a referendum?

I don't trust any referendum I didn't rig for myself.

There is no plurality in Ukrainian media. It's all controlled by Kiev. All the opposition channels are blocked.

Including Slashdot, apparently. :D

Battle of the Heavy Lift Rockets

K. S. Kyosuke Re:No miracles (197 comments)

I believe that methane was actually chosen (among other reasons) so that the stage (and the engines) could be more easily reusable: unlike kerosene, it shouldn't create an awful residue all over the fuel system.

Battle of the Heavy Lift Rockets

K. S. Kyosuke Re:Competition is good. (197 comments)

If you look at census data, wealth inequality across gender and race has massively dropped, all while median incomes (adjusted for inflation) have nearly tripled.

Why the sudden mention of race and gender? Is that because only white males invent rockets or something?

IBM Opens Up Its Watson Supercomputer To Researchers

K. S. Kyosuke BACON? (28 comments)

a cloud-based tool that will let researchers comb through massive troves of data, looking for insights and connections

Sort of reminiscent of BACON, isn't it? (With more intelligence, I presume.)

Should police have cameras recording their work at all times?

K. S. Kyosuke Re:"Accidentally" (378 comments)

If the cameras are everywhere where cops are, they do nothing more than to add accountability to the representatives of the government. Notice that these cameras simultaneously aren't where no cops are. ;-)

Radio Contact Lost With Vostok Station

K. S. Kyosuke K. S. Kyosuke writes  |  more than 2 years ago

K. S. Kyosuke (729550) writes "Russian scientists at the Antarctic Vostok Station, who have been trying to dig into the liquid heart of Lake Vostok, have suddenly gone silent.

The conditions in the lake are presumed to be similar to those of Europa and Enceladus and there is a hope that previously unknown forms of life could have found a niche in this unusual environment. Despite having been warned that their drilling technology (using freon and kerosene to lubricate the bore hole) may not be up to the task of reaching the lake without harmful enviromental side-effects, the Russians have decided to go on with the drilling. They haven't been heard from for the past five days."

HP releases AdvFS under GPL

K. S. Kyosuke K. S. Kyosuke writes  |  more than 6 years ago

K. S. Kyosuke (729550) writes "The battle for the "next-gen Linux file system" might have just become a little fiercer. Hewlett-Packard have just released their AdvFS file system under GPL. There is a press release on the HP web site, but the Wikipedia entry sports less PHB talk. The reaction of Sun and Oracle (each with their own advanced FS initiative, ZFS and Btrfs, respectively) to this might be interesting."
