It has been a while since I posted a vehicle here. Mainly because most of them are concept only and there are no prototypes. I prefer to include vehicles that have a real world version as it is more likely that some of the technology will work its way in to our next cars. However, this is a work of art and not unrealistic.

Deriving inspiration from kite boarding, the TEN11 has a motor placed in each wheel. The concept car derives its name from Bentley's logo itself, which sports ten feathers on the left and eleven on the right, Ten11. As this is designed to be an all electric vehicle, it is as environmentally friendly as the power source.

Ok, I couldn't quite come up with a headline on this one. The thing is, in order to make bricks we cut down trees. This new recipe uses sand, bacteria, calcium chloride and urea, all easy-to-come-by materials. The process does not require an outside heat source, so the trees are protected.

It seems like urea, is becoming quite a sustainable ingredient. Beyond being tapped as a good source of hydrogen used in fuel cell batteries it is now being used to make sustainable bricks.

Architect Ginger Krieg Dosier has designed a process to "grow" bricks by combining the materials listed above. Traditional brick-making is very energy-intensive, producing more pollution than global air travel each year. It also consumes a lot of resources: 400 trees are burned to make 25,000 bricks.

The new sustainable bricks are as strong as traditional bricks, maybe stronger depending on the recipe used for the traditional bricks. We need to keep an open mind about resources, I know some people will have a hard time with the idea of handling a brick made with urea, but keep in mind in chemistry it is just an acid.

Please take this statement to heart. I have two small children myself and I know it is difficult at times to sift through alarmist information to really know what is a potential hazard. One thing we know for certain is Lead poisoning is very real. We also know that Cadmium is a neurotoxin that can cause permanent brain damage if young children are exposed.

It took the CPSC nearly five months to act on AP tests, which identified the Claire's children's jewelry as a concern, since they are made with as much as 90% Cadmium. With this information, a ban on Cadmium in children's jewelry has been made. However, we can not be too careful because the damage is permanent. Please recycle any metal jewelry fitting this description if you are not 100% positive it is safe.

You can check recall information on the CPSC website.

CPSC Chairman Inez Tenenbaum warned manufacturers against using cadmium in January, while speaking in Hong Kong, but she had a more direct warning for parents:

"Because of these recent developments, I have a message for parents, grandparents and caregivers: Do not allow young children to be given or to play with cheap metal jewelry, especially when they are unsupervised," she wrote. "We have proof that lead in children's jewelry is dangerous and was pervasive in the marketplace. To prevent young children from possibly being exposed to lead, cadmium or any other hazardous heavy metal, take the jewelry away.... The key message that I want parents to know is: We will act to protect young children, but take the metal jewelry away from children who will swallow, suck or chew on it while our work continues."

At first glance, an article about Sony that implicates them with a little issue regarding their firmware upgrades hardly seems appropriate for an environmental blog. However, decisions like this by Sony and other companies can have far reaching impacts going all the way to the waste of materials and all that is involved with their life cycle.

Imagine for a moment, a company produces an electronic device, runs it to market in large quantities, the product is made obsolete within a year and those devices are processed straight to e-waste before their second birthday. What is the impact on the environment? This is hugely wasteful.

What Sony is doing is not intended to hurt the environment. However, their decision may have significant impact if the current issue is not cleared up. Let me summarize the situation and then I will do my best to explain it.

The Air Force originally purchased 300 PS3s for a special project. Next an order came through for 2,200 more, it seemed something serious was afoot, and sure enough the armed force was aiming to use them as a cluster for high-def video processing. Naturally that's quite dependent on the machine's Linux capabilities, capabilities that Sony has since disabled. You might think this doesn't matter, since the units will never play games and so don't need the crippling firmware update. But, hardware fails, especially when stacked as close as these units are and according to the Air Force's Research Laboratory, Sony takes the liberty of applying the latest firmware even to refurbished units.

As shown in the photo above, a cluster of computers can be wired together to work as one big computer. This is done with an advanced operating system like UNIX or Linux. As Linux is a widely used operating system in advanced systems and devices with specific functions it is used as the backbone of our military forces. So Linux is the choice for this project and in itself presents no problems that can't be resolved by the techs working on the project. However, Sony, in an attempt to protect their game machines from running software that is not Sony approved, has disabled very specifically the ability to run an operating system other than the one they supply with the machine. This means the Air Force will not be able to use their own software on the computers even though they own the computers after the point of purchase.

You can imagine why this is a complicated argument for both sides. As the owner, you should have the right to do as you like with what you own but as the producer, you have the right to modify the product to better suit its intended purpose and market.

If this is not resolved, we know there are 2,500 PS3's that will have a very short useful life. I don't want to see perfectly good electronic hardware go to waste over situations like this. In my opinion, Sony should embrace the military customer and recognize the added revenue stream as well as advertising zeal it may provide. At the same time, doing this and allowing the use of outside software for special cases would ensure the long useful life of the machines keeping the waste to a minimum.

If you are in the market for rechargeable batteries, there is very little difference in performance. The life of the batteries is claimed to be 2x by one manufacturer but the article did not have a long run test to verify they would outlast competitors by that amount. By the way, that is the number of recharge cycles, not how many hours they will run a device.

Average prices:

PowerGenix Batteries: $11
PowerGenix Charger Bundle: $23

Energizer Batteries: $12
Energizer Charger Bundle: $20

Eneloop Batteries: $10
Eneloop Charger Bundle: $21

As the article said, a safe bet is whichever is on special.
