Renewable Energy Saves Fortune 100 Companies $1.1B Annually

Muad'Dave Re:Actual savings? (116 comments)

The only downside to switching over to LED-filled fake fluorescent tubes is the cost of producing fake tubes that have to handle different input voltages. With the old ballast system the input voltage was handled by the ballast the the tube got the correct strike/run voltage/current regardless. Lots of SOHO fluorescent ballasts are designed to run off 120V and many that are installed in businesses are designed to run off 208V (high leg delta), 240V (phase to phase), 277V (phase to neutral in a 480V wye), etc.

If the LED tube power supply is intelligently designed, they should be able to accept 120V-277V much like modern wall warts do - the challenge will be making them efficient at the same time.

NASA's Orion Spaceship Passes Parachute Test

Muad'Dave Re:terminal velocity on mars (75 comments)

What's the terminal velocity on Mars?

Same as on Earth -- Zero. You're not terminal until you smack into the planet. Do you mean "Maximum screaming for your life velocity"? You hit that just before hitting terminal velocity.

It's a joke, Son.

Trio of Big Black Holes Spotted In Galaxy Smashup

Muad'Dave Re:Please explain (74 comments)

For all intents and purposes, the objects are the same distance from Earth. They're 450 light-years from each other and both are approximately 4.3 BILLION light-years from Earth. The maximum difference in distance between object A and Earth and object B and Earth is 0.000010465116% (450 / 4.3x10^9 * 100). Close enough to the same distance. For reference, the same delta applied to 1 AU (93,000,000 mile Earth-Sun distance) yields 9.73 miles.

It's Not a Car, It's a Self-Balancing Electric Motorcycle (Video)

Muad'Dave Re:No (218 comments)

I love laws that are written that way. The state of Virginia automobile inspection laws are equally as circumspect. They say things like 'Door handles must be operable from inside the car.' That does not mean that there have to be door handles installed, just that they have to be operable from inside if they exist.

Four Weeks Without Soap Or Shampoo

Muad'Dave Re:Does shower mean soap? (250 comments)

I'm also curious about your anecdote, was this gentleman aware of his odor? If so, how was he made aware? You mentioned a second opinion from an unbiased source, can you be more specific?

It depends on your definition of 'aware' - had he been told, yes. Could he sense it? I don't think so. I don't think he believes it when told there was a problem because I truly believe he couldn't smell it himself. It would be like trying to convince a pre-19th century person that disease was caused by tiny critters he couldn't see and not bad air that he could clearly smell.

As for the unbiased second opinion, I was suggesting to the OP that he ask someone who's not a friend or family (his words). Perhaps a doctor or nurse at his next checkup, or some other person who has no vested interest in telling him what they think he wants to hear; no one wants to delivery the news that "you stink".

Four Weeks Without Soap Or Shampoo

Muad'Dave Re:Does shower mean soap? (250 comments)

Using soap in general isn't something I feel is needed since a regular rinsing leaves me non smelly.

According to your nose you may be non-smelly. Perhaps you're like a coworker of mine that could not smell BO. He didn't think he needed to wash regularly or use deodorant since he couldn't smell himself. Being an avid runner, he STANK most of the time; I mean he reeked to the point of making people's eyes water.

You really don't want to be 'that guy'. You might want to get a second opinion from an unbiased source (not "friends and family").

NRO to declassify Cold-War Spy Sat Tech

Muad'Dave Muad'Dave writes  |  more than 2 years ago

Muad'Dave (255648) writes "The National Reconnaissance Office is set to reveal details of two of the cold war's most capable spy satellite programs on September 17th — the GAMBIT and HEXAGON projects, aka the keyhole KH-7, -8, and -9 satellites. These bus-sized sats provided critical imagery during the height of the cold war, and were likely the inspiration for the movie "Ice Station Zebra".

The article links midway down the first page provide a fascinating look into the world of real spy-vs-spy, cloak-and-dagger intelligence gathering."

US Air Force secret X-37B orbiter lands

Muad'Dave Muad'Dave writes  |  more than 3 years ago

Muad'Dave (255648) writes "The US Air Force's secret X-37B orbiter landed at Vandenberg AFB early this morning. Amateur satellite watchers determined the orbit and detected several orbital maneuvers. From the press release:

30th Space Wing Public Affairs

12/3/2010 — VANDENBERG AIR FORCE BASE, Calif. — The U.S. Air Force's first unmanned re-entry spacecraft landed at Vandenberg Air Force Base at 1:16 a.m. today.

The X-37B, named Orbital Test Vehicle 1 (OTV-1), conducted on-orbit experiments for more than 220 days during its maiden voyage. It fired its orbital maneuver engine in low-earth orbit to perform an autonomous reentry before landing.

The X-37B is the newest and most advanced re-entry spacecraft. Managed by the Air Force Rapid Capabilities Office (AFRCO), the X-37B program performs risk reduction, experimentation and concept of operations development for reusable space vehicle technologies.

"Today's landing culminates a successful mission based on close teamwork between the 30th Space Wing, Boeing and the Air Force Rapid Capabilities Office," said Lt Col Troy Giese, X-37B program manager from the AFRCO. "We are very pleased that the program completed all the on-orbit objectives for the first mission."

OTV-1's de-orbit and landing mark the transition from the on-orbit demonstration phase to a refurbishment phase for the program.

The Air Force is preparing to launch the next X-37B, OTV-2, in Spring 2011 aboard an Atlas V booster."

Target pharmacy begins scanning driver's licences

Muad'Dave Muad'Dave writes  |  more than 4 years ago

Muad'Dave (255648) writes "This evening I picked up my regular prescriptions at my local Target pharmacy. As I was paying for them, the cashier asked to 'see my ID'. That was not typical, but I assumed she was going to verify the photo. Before I could stop her, she flipped it over without looking at the front and scanned the 2D barcode on the back. I asked her why she did that, and her answer was that the system 'required' it.

I went to the customer service desk and asked them why they thought they were entitled to scan my license. Their first answer was that it was a convenient way to validate my birthday, and that was all that was on the 2D barcode. When I mentioned that I know there's more data than that, she then said that it was a convenient way to verify that the ID was present. I mentioned that verifying the presence of an ID required more data than the DOB, and she agreed, contradicting her earlier statement that all they scanned was the DOB.

The is a Federal law addressing who can and cannot scan licenses, but it's so full of loopholes as to be useless.

Apparently I'm not the only one bothered by their attitude on privacy.

Have you been subjected to this invasion of your privacy by Target?"

Satellite debris forces ISS crew into rescue craft

Cheap, super-efficient LEDs on the horizon

Muad'Dave Muad'Dave writes  |  more than 5 years ago

Muad'Dave (255648) writes "According to this article, cheap Gallium Nitride LEDs are now possible, thanks to a process that controls the rate at which GaN shrinks when cooled, making it possible to grow GaN on silicon.

"They included layers of aluminium gallium nitride in their LED design. These layers shrink at a much slower rate during cooling and help to counteract the fast-shrinkage of pure gallium nitride. These LEDs can be grown on silicon as so many other electronics components are."

"A 15-centimetre silicon wafer costs just $15 and can accommodate 150,000 LEDs making the cost per unit tiny. That levels the playing field with CFLs, which many people only ever saw as a stopgap solution to the lighting problem.""

The Re-Entry of ATV: One Final Experiment

Muad'Dave Muad'Dave writes  |  more than 5 years ago

Muad'Dave (255648) writes "The SETI Institute, in cooperation with the European Space Agency is organizing a mission to record the fiery breakup of the ATV/Jules Verne spacecraft as it re-enters Earth's atmosphere on September 29th.

From the article:

A documentation of the breakup process could help validate the models built to study how that fragmentation evolves in a series of disruptions of major components. At reentry into the atmosphere, ATV would execute one final experiment before the mission completion. Our experience with meteor spectroscopy carried the promise of perhaps being able to identify some of the fragments from their radiation signatures. The ATV-1 "Jules Verne" Multi-Instrument Aircraft Campaign was born. "

Opportunity Takes a Dip Into Victoria Crater

Muad'Dave Muad'Dave writes  |  more than 6 years ago

Muad'Dave (255648) writes "From the NASA News Release:

Today, NASA's Mars Exploration Rover Opportunity entered Victoria Crater for the first time. It radioed home information via a relay by NASA's Mars Odyssey orbiter, reporting its activities for the day. Opportunity drove far enough in — about four meters (13 feet) — to get all six wheels past the crater rim. Then it backed uphill for about three meters (10 feet). The driving commands for the day included a precaution for the rover to stop driving if its wheels were slipping more than 40 percent. Slippage exceeded that amount on the last step of the drive, so Opportunity stopped with its front pair of wheels still inside the crater.

This marks the beginning of perhaps the greatest 'Opportunity' for new discoveries on Mars."
