Billion-Pixel View of Mars Comes From Curiosity Rover This is a reduced version of panorama from NASA’s Mars rover Curiosity with 1.3 billion pixels in the full-resolution version. It shows Curiosity at the “Rocknest” site where the rover scooped up samples of windblown dust and sand. Curiosity used three cameras to take the component images on several different days between Oct. 5 and Nov. 16, 2012. Viewers can explore this image with pan and zoom controls at http://mars.nasa.gov/bp1/. Image credit: NASA/JPL-Caltech/MSSS

“Dead” Satellites Can Be The Newest (And Nearest) Valuable Resource To Harvest From Space [VIDEO]

In an era when companies are seriously talking about mining asteroids, there is an enormous untapped resource in space which is as close as low Earth orbit (LEO), and which is otherwise classified as ‘space junk’: Dead satellites. Continue reading

People of the Lake – Al Jazeera English [VIDEO]

The Aral Sea, located between Uzbekistan and Kazakhstan, was once the fourth-largest lake in the world – an immense body of fresh water covering a surface area of 68,000 square kilometres.

Two port cities were located on it – Aralsk in Kazakhstan and Moynaq in Uzbekistan. Both featured thriving fishing communities and the lake itself held some 22 different varieties of fish – four of which could only be found in the Aral.

“This is a crime against nature. The drought of the Aral Sea is a man-made tragedy.– Sergei Azimov, a film producer

But then the Soviet Union decided to boost cotton farming by constructing dams

on the two large rivers that flowed into the Aral Sea, the Amu Darya and the Syr Darya rivers.

This diverted these two giant rivers away from the sea into the deserts further south to irrigate large tracts of land. It proved disastrous for the Aral Sea.

KITTYCAM: What Your Sweet, Harmless Little Kitty Is Doing When You’re Not Watching [VIDEO]

 Your cat has a secret life when it’s outside. The Kitty Cam project is an attempt to see the world they way your cat does when you’re not watching. The videos are ‘rough’ (cats make poor cinematographers), but as a peek into an unknown feline world, are fascinating.

Looks Like Nuclear Weather… Men watch 2-kiloton nuke detonation, from underneath it! [VIDEO]

George Yoshitake, Don Luttrell, and four other officers stood directly  underneath an exploding nuclear warhead 55 years ago — and lived to tell their  tale.

The blast was just a test, a bit of Cold War marketing designed to make the  concept of nuclear war less scary for the public, but the 2-kiloton atomic  explosion set off over the Nevada nuclear test site (and over the heads of those  six men) was very real.

Florida Government Complicit in Negligent Homicide?: Worst TB outbreak in 20 years kept secret

Worst TB outbreak in 20 years kept secret

State rushes closure of its only TB hospital in Lantana

JACKSONVILLE — The CDC officer had a serious warning for Florida health officials in April: A tuberculosis outbreak in Jacksonville was one of the worst his group had investigated in 20 years. Linked to 13 deaths and 99 illnesses, including six children, it would require concerted action to stop.

That report had been penned on April 5, exactly nine days after Florida Gov. Rick Scott signed the bill that shrank the Department of Health and required the closure of the A.G. Holley State Hospital in Lantana, where tough tuberculosis cases have been treated for more than 60 years.

Microwave Ovens vs. Microwave/Convection Ovens vs. Microwave/Halogen Ovens

[12/8/2013: This article was modified for clarity.]

For about 10 years, I sold appliances, among other things. While model-specific knowledge has passed me by, I’m still familiar with many points relating to technology, applications, useful features, features to avoid, and user errors which create some problems.

For my Chinese in-laws, I sometimes suggest appliances which may be helpful to them, but which may not be common in the People’s Republic of China (PRC). In such cases, I write ‘helpful hints’ emails to assist them in finding equivalents. In many cases, they must educate the Chinese sales people with whom they deal, who themselves may not be familiar with Western-style appliances which we take for granted. (As an example, only 1% of Chinese households have automatic dishwashers, and sales people are usually unfamiliar with how to use them  effectively and safely, let alone what features are useful for solving a customer’s  needs or desires.)

Below my bullet points, I’ve pasted some examples. If you live outside the United States, you will probably have to look for comparable domestically-available units.

Wind Turbines: “It’s always something” [VIDEO]

UPDATE, 4/30/2012: Along the lines described in this piece: NASA Satellite Measurements Imply Texas Wind Farm Impact On Surface Temperature

UPDATE: 4/9/2012: On Wednesday, April 11th, I’ll be doing a show on Energy Independence on KPFT-FM 90.1 (Houston). You can read about the show and how to hear it here.

Since wind energy will be a topic of discussion, it seemed like a good time to re-post this piece, originally written by me in April of 2010.

It seems that wind turbines change how heat dissipates in the areas downwind of them, because they slow the wind as it spins their propellers. Once one begins to think about it, this domino effect makes perfect sense.
