Motor is 3300KW @ 6.6kV
I know this does not make sense but :
Motor does not run up but reported to behave as though single or 2 phasing
Switchboard voltage drops by around 500V, even when motor was started uncoupled from its pump
Motor PI, IR & winding balance tests all ok
We've seen batteries charged by outlets and by cranks, but this concept from designers Song Teaho and Hyejin Lee is the first that charges with a twirl.
However, like all things tagged concept, this battery doesn't *technically* exist yet.
Still, Teaho and Lee both hypothesize that this battery, should it become the real deal, would require about 130 twirls for two-minutes talk time.
From what I've seen of crank-charged batteries, that seems relatively plausible (and tiring). Get to work, fellas. [design(dot)fr via Engadget]

The few times I go bowling each year are more about pitchers of cheap beer than they are satiating some desire for the perfect game, but nevertheless I'm intrigued by this "smart ball" from the Royal Melbourne Institute of Technology.
Developed by sports scientist Franz Fuss, the smart bowling ball contains aluminum tubes in the finger holes that track the force a bowler applies to each roll. Fuss had ten bowlers of different skill levels bowl various shots down the lane, measured the force, and used it to try and find the perfect shot.
The simple system found that the better bowlers were consistent (surprise!), in that they always pinched the ball with "much greater force prior to release." This allowed for a much faster delivery than the newbs, and of course higher scores. [New Scientist]
STS-130 Shuttle flight facing delay due to Payload technical glitch, Universe Today
"The launch of Shuttle Endeavour on the STS 130 flight now faces a potential delay due to technical problems with the external ammonia connecting lines which are designed to provide critical cooling capability to the new Tranquility module. Tranquility is a pressurized module being brought aloft as payload in the cargo bay of Endeavour on the STS 130 mission. Launch of Endeavour is currently set for 4:39 AM on Feb. 7."

The Westminster Chiming Grandfather clock is an obelisk of discarded toys. At 2.2 meters tall, it's also a monstrous, functioning timepiece that now resides in, where else, Dubai.
But how was it created? Well, just a little Buzz Lightyear here, Hulk action figure there, and then a coat of high gloss polyurethane white paint to seal everyone in.
There are more out there, says designer Ryan Mc Elhinney, with the toys used symbolizing the client's childhood memories. This leads me to believe some clocks are far scarier than others. [Dezeen]

Is there a cheap and dirty way to prevent back-flow from an improperly plumbed washing machine drain? It goes up about 8 feet to a DW line with a check valve in between. The check valve gets clogged up from washer waste (seems obvious) and fails to prevent contaminated waste drain from flowing do

The Microvision pico-projector video game gun controller we profiled last month might actually see the light of day—and soon. Who's ready for some murky, awkward angle FPS fun?
I mean, I kid Microvision about the fact that you'd need a cylindrical room with nothing on the walls and no light to use this controller properly, really, but nevertheless—my angst aside—there seems to be enough demand in place that their CEO is going to market this thing sooner rather than later.
CEO Alexander Tokman said manufacturer samples are slated to be sent out later this year, with cellphone, video game and other markets creating real, live products sometime in 2011. Because random, screaming kids playing Gears of War 2 on the side of the subway during the morning rush would be totally cool with me... [Projector Info]

Much like the multi-million dollar jet systems that inspired it, the Saitek Pro Flight X65F joystick/throttle system for PCs doesn't move at all. That's right, not an inch, and yet the controls were compared to mind control. [ars technica]
The X65F uses "force sensing" tech, just like military planes today. In layman's terms, that means no moving parts.
Apply subtle pressure to the 'stick, and your plane banks and turns on a dime.
Twist the controller for precise rudder control, writes ars technica, and then before you know it the joystick is performing almost like an extension of your hand.
Dual engine control for games that support it, or lock them together for games that don't.
Saitek claims that with the X65F there are 608 possible commands a player can issue without ever taking their hands off the controls.
And while the X65F won't cost you millions, it certainly isn't cheap at $400. This is not including the optional "Saitek Pro Flight Instrument Panels" that you can bolt on the back for a crazy amount of realism. [Saitek via ars technica]
Anyone feeling extra geeky today? Well you should. Today's date, when written in a six digit format (MMDDYY), is a binary style number. Updated.
Writes reader Eric, who tipped us off about the date earlier this morning:
It just occurred to me that today's six digit date format (MMDDYY or YYMMDD) is in binary style. Thought this was interesting and wanted to share it with the Gizmodo team. From what I can tell, this looks like it will be the only year it happens and will happen four times (January 1st and 10th and October 1st and 10th).
As you can see, this neat little phenomenon will happen a few more times throughout this year and next. 2010: Geekiest year ever? Update: As noted below, "Oct. 10th 2011 November 11, 2011 will be the last binary day of this century."
Legendary Gods of Rock lived up to their libertine reputation
James Jackson of The Times on-line recently conducted an interview with Led Zeppelin lead guitarist, the legenday Jimmy Page. The lengthy piece, "Jimmy Page on Led Zeppelin's good times, bad times and reunion rumours" ran in The Times, Jan. 8.
Jackson discovered Page might be planning an autobiography. On a possible Zeppelin reunion tour in the coming months, Page took a somewhat pessimistic line:
"I don’t have any real answer, apart from that it doesn’t look like it."
Then Jackson delved into the past. Continuing:
However much he frowns about the more exotic speculations laid on him — that he was an occultist, that he carried a collection of whips for use on gleeful groupies, that he spent a tour living on nothing but daiquiris and heroin — they play a formidable role in Page’s irresistible mythos.
How much of those, ahem, libertarian days of yore can he even remember? “When I look back at it it’s still in focus. Most of it is clear.”
Stories of the band’s groupie-tastic, coke-fuelled, booze-binging exploits on tour have captivated the imagination of rock fans ever since. If their excess wasn’t really anything their peers weren’t doing too, then Led Zeppelin’s imperious, untouchable manner, their private jet, the accompanying chaos set them apart, evoking to this day the ultimate rock-stars-on-the-road fantasy. Anecdotes concerning Page being served on a room-service trolley to a room of nubile young women sound like any lusty young man’s dream. But Page has never and won’t substantiate — or deny, it should be said — any of the wild tales.
But Page said in the end "what's most important about Zeppelin is the music."
