Algae and China’s Olympics

The AP reports that competitors in Beijing may face environmental challenges:

To host the Olympic sailing events, the Chinese port city of Qingdao moved a massive boat yard, relocated industries and spent about $850 million on transport links, parks, pollution controls and coastal green belts.

But with little more than a month to go until the Games, a different challenge is cropping up: A forest of blue-green algae is choking the coastal waters, suffocating beaches and lying in thick layers along sailing routes.

The Olympic committee should bar any country from applying to host the games if they can not achieve environmental guidelines such as air and water quality.

The New York Times had an interesting look at cause:

Water quality has been a concern for the Olympic sailing events, given that many coastal Chinese cities dump untreated sewage into the sea. At the same time, rivers and tributaries emptying into coastal waters are often contaminated with high levels of nitrates from agricultural and industrial runoff. These nitrates contribute to the red tides of algae that often bloom along sections of China’s coastline.

But officials in Qingdao this week said pollution and poor water quality did not have a “substantial link” to the current outbreak, according to Xinhua. Instead, scientists blamed the bloom on increased rainfall and warmer waters in the Yellow Sea. Algae blooms now affect more than 5,000 square miles of sea water, according to Xinhua.

Regardless of cause, the real question is impact. I guess the 10,000 people who are cleaning up all the algae could be tested for ill effects, as well as all the animals fed the stuff:

Photographs in the Chinese media showed rickety wooden boats overflowing with green mounds of algae collected from the sea. One photo showed a young boy crouched on a beach beside piles of the leafy glop as a dump truck carried off a large load of algae. State media reported that 100,000 tons of the algae had already been taken out of the water. Much of it was being transported to farms as feed for pigs and other animals, according to news reports.

Maybe the Chinese could convert the Algae into biodiesel? It is great the Olympics are forcing China to clean up, but the clean up should come long before the games so these risky and questionable quick-fix solutions would not be necessary.

Biometric Surveillance Proven on Penguins

Uniqueness and patterns in penguin breast feathers have been used by a video surveillance system to monitor tens of thousands of the birds, according to the BBC:

Professor Barham said: “We set a camera up in a location where the penguins will regularly walk past on their way to or from the sea.

“Every image that the camera processes is then sent back to a computer.”

The software has been trained to recognise if there are any penguins in the camera’s field of vision. If there are, it looks at the spot patterns to determine whether it is a bird that it recognises or new penguin. It then records and ID number and the date, time and location of the sighting.

How do the scientists prove uniqueness? Naturally the system will be soon discussed in terms of leopards, zebras, cheetahs and other patterned animals. Even if humans do not have uniquely patterned feathers or fur, it seems to me this technology will eventually make its way into correlation engines that can track a suspect with certain features and provide a single storyline across multiple cameras. On the other end of the spectrum, pun not intended, humans are getting more savvy at using infrared LED to completely disguise themselves from night-vision surveillance. This defensive maneuver might prevent identification of the person, but a pattern-matching system perhaps would still be able to track and report on that person’s movements.

While the privacy debate continues around video surveillance, the BBC also reports that audio surveillance has started to be integrated into camera systems:

Dr David Brown, from the University of Portsmouth, said: “The visual-recognition software will be able to identify visual patterns but for the next stage we want to get the camera to pivot if it hears a certain type of sound.

“So, if in a car park someone smashes a window, the camera would turn to look at them and the camera operator would be alerted.

This seems a reduction of usefulness, in some ways, as sounds are often a distraction more than an aid. If you read the article you will find some optimism for pattern-matching technology. For example, the researchers plan to be able to detect breaking glass versus other sounds. They do not mention if someone throwing a bottle would actually be a simple defensive measure to divert the camera. And what if you throw the bottle at the same time that you break a window?

I would love to test these systems.

The future market of energy

This story is what the future of energy is all about:

The company stuck solar panels on UCSF’s Genentech Hall as well as a nearby parking garage. MMA owns the panels and sells the power to the school, under a contract that locks in electricity prices for the next 20 years. The rates are lower than Pacific Gas & Electric’s, and the school didn’t have to pay for the panels up front.

“It’s very simple – we got someone else to take on the headaches, and we get the power,” said Maric Munn, the school’s director of facilities management.

In other words, generation of energy needs to become more localized and democratized in the same way that PCs changed the information generation model from mainframe and slaves to networked peers.

The advantage of diesel in this model is that it has many more options than most power generators — the input can come from virtually anywhere. Thus if the output is standardized, the market for micro-generation could explode.

Excellent story.

Mobile Brothel Busted

An undercover investigation by the Florida police, as told on Officer.com, has revealed a brothel operating in a strange location:

A sleek, black limousine bus parked just a block from Miami Beach Police Department headquarters was being used as a brothel on wheels, a place where clients could come to solicit sex from prostitutes, police said.

Ok, so that was obviously a bad idea, but does anyone know if Krispy Kreme has thought about a bus full of donuts…?
