Invention - the Image Fulgurator

by Marshall Brain

This is one of those ideas that is really simple, but really unique, and when you hear it you wonder why it took someone so long to think of it.

The Brains Behind the Image Fulgurator

There is tool called a “slave flash” that has been used in photography studios for decades. When one flash goes off on the camera, a slave flash senses it it also goes off. In a studio, it means that two or three or four flashes all go off at once and provide very nice lighting. This is one reason why studio shots look better tan “normal” photographs.

The imagine fulgurator uses the slave flash idea to push out an image whenever it sees a flash goes off. That image appears in the photograph that someone else is taking. The IF does this by using a “camera in reverse” - the slave flash fires at the back of the camera, through a slide, so the image comes out through the lens of the camera.

The implications? From the article:

Now, imagine for a moment that an ad agency gets hold of this. You couldn’t take a photograph of a tourist attraction ever again without worrying that some marketing crap would be pushed into your camera.

Predicition - oil at $170 by end of 2008

by Marshall Brain

The prediction is made by OPEC President Chakib Khelil:

OPEC Leader Khelil Says Dollar Will Drive Oil to $170

Here’s the predicition:

the price of oil will climb to $170 a barrel before the end of the year, citing the dollar’s decline and political conflicts.

“Oil prices are expected to reach $170 as demand for fuel is growing in the U.S. during the summer period and the dollar continues to weaken against the euro,” Khelil said today…

Interesting - 9 Extraordinary Human Abilities

by Marshall Brain

Certain human beings have abilities that amaze the rest of us. This article talks about nine of them:

9 Extraordinary Human Abilities

Here are the nine listed in the article:
1) Supertaste
2) Absolute pitch
3) Tetrachromacy
4) Echolocation
5) Genetic Chimerism
6) Synesthesia
7) Mental calculators
8) Eidetic memory
9) Immortal cells

There are a couple of other abilities that come to mind that I would add to this list:

1) The ability to draw what you see. You can actually learn to do this pretty well with a book like “Drawing on the right side of the brain”
2) The ability to draw what you imagine
3) The ability to sculpt at all, but especially from imagination
4) The abilities of certain athletes to calculate trajectories, like a football quarterback throwing a pass while falling, or Tiger Woods hitting a golf shot.
5) The ability of muscicians to invent a song out of thin air that people like to hear.
6) The ability of interior designers to arrange objects in pleasing ways. A “normal person” using the same objects will create a boring room. A designer makes them appealing in ways that are surprising.
7) The ability to invent. There are definitely people who are better at this than others.
8) The ability to talk fluently in public off the top of your head. Talk show hosts, commedians and some politicians have this. Most people don’t.
9) Then there are the special geniuses, like chess geniuses, stock geniuses, cooking geniuses, etc.

Dragster crashes

Last week the Scott Kalitta accident was a reminder of how dangerous drag racing can be:

As you search through YouTube, you realize how common accidents are in drag racing:

Why do the dragsters look so fragile? In several of these videos they seem to fold up like paper. It’s because, to keep the weight as low as possible, there just isn’t much to a dragster. It’s a spindly space frame bolted to an immense engine. At 300 MPH the force of the wind is incredible compared to the strength of the frame. This page helps you see how fragile a dragster really is:

How the Oyster Card (for the London transit system) doesn’t work

by Marshall Brain

If you ride the transit system in London, you use an Oyster card to pay your fare. Oyster cards have an RFID chip inside to keep track of your account balance. Here’s how you recharge an Oyster card:

This video shows you what the RFID chip and its antenna looks like after you remove it from the card:

This week Dutch researchers figured out how to hack this RFID-based system and get free rides, as described in this article:

Hackers Crack London Tube’s Ticketing System

From the article:

The hackers scanned one of the Underground’s many card readers to collect the cryptographic key that purportedly keeps the system secure. The keys were uploaded to a laptop, essentially turning them into portable card readers. The hackers then brushed up against passengers to wirelessly upload the information on their Oyster cars. That information in hand, it was a simple matter of using it to program new cards.

This article goes into a little more detail about how the system works:

Oyster card security broken

The basic problem seems to be a poorly designed security system that is very easy to crack.

Interesting - The Duke microrobots

by Marshall Brain

People have been imagining tiny robots that can perform surgery inside the human body, or tiny robots that assemble themselves into something bigger. A lab at Duke university is experimenting in this realm:

Duke team creates a fleet of crawling robots

From the article:

Donald and his team of Duke University computer scientists have constructed a fleet of fully steerable microrobots small enough to move around on the head of a pin. Robots this small could some day explore brain tissue or manipulate delicate electronics.

The robots are about 250 microns long and 60 microns across. They are thinner than the width of a human hair, and you could line two of them end to end inside the period at the end of this sentence.

They look like spatulas that move around on a charged surface using small, spring-like steps similar to an inchworm’s crawl. The microrobots have a long thin arm that can be lowered and used as a pivot for turning, allowing the machines to steer freely in any direction.

This video shows the robots at work:

Prediction - the computer mouse is dead

by Marshall Brain

The Mouse Is Dead

From the article:

The evolution of user interfaces, in fact, can be viewed as a process of getting the user “closer” to objects on-screen. In the beginning, we interfaced with computers on the other side of the glass, handing punch-cards to an operator for processing. Then we typed abstract commands, but directly on a keyboard. Then we used a mouse to simulate the grabbing and selecting, the dragging and dropping of on-screen objects. In the coming fourth phase, we’ll reach out and touch documents, photos and folders directly using iPhone-like user interfaces.

In these four phases of human-computer interaction, the mouse was of use in only one of them. And that era is about to draw to a close.

He’s right on handheld devices and laptops. I happen to be skeptical of this on desktop computers. If you go way, way back (like the 1970s), there used to be something called light pens that did let you directly interact with the screen (see a photo of a light pen here). But light pens were replaced by mice because mice are a lot more comfortable to use. Even if your desk was made of a glass screen acting as the tabletop, you would still have to hold your arms out in front of you and move them around a lot. A mouse lets your arm rest on the table and a little flick of the wrist carries the cursor from one edge of the screen to the other.

We will see how long the desktop mouse survives.

As you look at the site, on the left you have two rows of sphinxes that line the entrance walkway. Then you enter the temple courtyard (center of the image) by walking between two giant walls. Off to one side of the courtyard is the Temple of Ramses III. And then there is a sea of columns on the right. You can get a sense of the scale of this structure from these two videos:

This page offers a very nice walk-thru of the temple, with 360-degree views and descriptions:

Public Service Announcement - Lead may be poisoning you

by Marshall Brain

Are you suffering from the effects of lead poisoning? Apparently there is a 40% probability that you are. This video talks about the effects of low-level lead poisoning:

From the video:

But this new study and others like it bring the idea of ANY safe level of this toxic metal into question. What this study found was that any level over 2 - not 10 or 40 - 2 in the blood, caused dramatic increases in heart attacks, strokes and death. In fact, after controlling for all the other risk factors, including cholesterol, high blood pressure, smoking, inflammation, that the risk of death from all causes increased by 25%. Deaths by heart disease increased by 55%. The risk of heart attacks increased by 151% and the risk of stroke increased by 89%. What was more remarkable is that 40% of Americans had toxic levels of lead - enough to cause these problems.

There’s a simple blood test that can tell you your lead levels. The video offers a number of suggestions for dealing with the problem.

Good question - Can a Million Tons of Sulfur Dioxide Combat Climate Change?

by Marshall Brain

If the planet is warming because of greenhouse gases, then the problems that we will see over the next several decades are profound. We’ve all seen the disaster scenarios - everything from flooded coastal cities to stronger inland storms.

Assuming we are unable to get greenhouse gases under control, how do we cool the planet? The most obvious way is to reflect away some of the sunlight that the planet normally receives. One way is to put mirrors in space that directly reflect sunlight. Another is to add clouds to the atmosphere, as explained here:

A third way is to pump millions of tons of sulfur dioxide into the stratosphere in the same way that volcanoes do. Would it work? Here’s the answer:

Can a Million Tons of Sulfur Dioxide Combat Climate Change?

From the article:

The stratospheric sulfate experiment has already had its proof of concept — courtesy of planet Earth. On June 15, 1991, Mount Pinatubo, which for months had been rumbling, belching, and terrorizing the main Philippine island of Luzon, finally blew its top in an explosion so powerful that it carried 500 feet of the mountain’s peak along with it. It was the second-largest volcanic eruption of the 20th century, 10 times the size of the Mount Saint Helens explosion in 1980 and the first of its scale to occur with modern scientific technologies in place — especially satellites — to measure the global environmental and climatic effect.

Pinatubo’s eruption didn’t just unleash huge mud slides and lava flows; it also fired an ash stream 22 miles into the air, injecting 20 million tons of sulfur dioxide into the stratosphere. Over the following months, a massive haze gradually dispersed across the globe. Meanwhile, the sulfur dioxide component underwent chemical reactions to form a particulate known as sulfate aerosol (in essence, droplets of water and sulfuric acid), which absorbs sunlight and reflects some of it back into space.

The climatic effect of this volcanic eruption was rapid, dramatic, and planetary in scale. In a year, the global average temperature declined by half a degree Celsius, and researchers observed less summer melt atop the Greenland ice sheet.

How the water-powered car doesn’t work

by Marshall Brain

Reuters released this story about a water powered car. It is a top-5 most watched video on YouTube today:

Supposedly the car is powered by nothing but water, and “a liter of water will keep the car running at a speed of 80 kilometers for about an hour.”

How does this work? According to the video:

Once water is poured into the cars tank, an energy generator takes hydrogen from the water, releasing electrons that power the car. “The main characteristic of this car is that no external input is needed. The car will continue to run for as long as you have a bottle of water inside for you to add from tme to time.”

This sounds great. You can get water from your tap for a penny per gallon and power your car with it. Is this for real? Of course not. As we discussed in Ode to Stanley Meyer, either it is a pure hoax or something else is going on.

If something else is going on, this article explains what is probably happening:

Genepax Water Car: Too Good to be True? Yeah

From the article:

The way it’s usually done is with metal hydrides. These react with water to produce hydrogen, which is then used to power the car. But since these hydrides will deplete with time, they need to be replaced and so they are actually the fuel, not the water. And you can be sure that more energy will go into producing them than will be taken out, making them an energy carrier, just like a battery…

Sodium Borohydride is one of these metals, and it could become a great energy carrier. It is fairly easy to recycle Sodium Borohydride after you use it in your car. Mainstream car manufacturers have demonstrated fuel cell cars that use sodium borohydride:

Chrysler Natrium: The Power of Na

Here is a nice explanation of how it works:

Hydrogen Storage via Sodium Borohydride

The key thing to understand is that you have to put energy into the process of recycling sodium borohydride. That is why it is an “energy carrier” rather than a “fuel”.
