The Nissan Leaf

August 3rd, 2010

Nissan’s unveiling of the LEAF jolted green car fans on the web. No longer an amorphous concept, Nissan’s electric car is stacked up against other plug-in cars and hybrids for its look and feel and features. The reviews from the blogosphere—usually an irreverent crowd—have been mixed.

The Nissan LEAF’s closest comparable future all-electric car is the Ford Focus EV. The two vehicles are remarkably similar in size and capabilities. Both vehicles are expected to offer 100 miles in driving range. The Nissan LEAF’s lithium ion battery pack has a capacity of 24 kilowatt hours, while the Focus EV holds 23 kilowatt hours of energy. Both vehicles will carry five passengers and measure 175 inches in length, while the Nissan LEAF has a longer wheelbase by about three inches.

Although the Nissan LEAF is expected to beat the Ford Focus EV to the market by about one year, LEAF’s first customers will be fleets and consumers participating in Department of Energy evaluations. The LEAF’s distinguishing characteristic could be design. When we spoke last November with Mark Perry, Nissan’s director of product planning, he said, “We want to make sure [the design] is iconic, as something different, unique and futuristic. But not in a Blade Runner, George Jetson kind of way.”

The Nissan LEAF will be arriving almost exactly when the Chevy Volt is introduced in late 2010—although it appears that the Volt will be priced several thousand dollars higher than the Nissan LEAF. While more expensive, the Chevy Volt is a plug-in hybrid offering a driving range equal to or beyond most gas-powered cars, while the Nissan LEAF, Ford Focus EV, and other electric cars will be limited to approximately 100 miles in range. The new plug-in cars will also be competing against conventional hybrids, like the Toyota Prius and Honda Insight, which are priced in the low- to mid-$20,000s.

When all these choices become available, consumers interested in cutting-edge fuel-efficient technologies will have to make sense of the new automotive landscape—balancing considerations for driving range, price, fuel efficiency, drivetrain technologies, and design.

It’s hard for me to deny that I wish this automotive future could kick in sooner than later. I’m growing disgusted of the amount of pollution that’s literally changing the looks and feel of every town/city. I still remember when 10/15 years ago traffic was non existent in the country side, and I have a pretty clear picture of the difference from then and today. Driving up-hill is a revolting experience nowadays, shall I find a gasoline fueled vehicle pumping its nauseating gases in front of me. One day, soon I hope, this MUST be the future of city cars. I am pretty sure my next car (whenever I’ll happen to be buying a new one) will be electric.

12 Facts About ‘StarCraft’ You Might Not Have Known

July 23rd, 2010

Asylum.com has posted an interesting article regarding one of Blizzard’s most awaited sequels:

For a franchise that’s finally getting its first full-fledged sequel more than 10 years after its original game was released, real-time strategy hit “StarCraft” has managed to stay on the radars of gamers worldwide through numerous expansion packs and expertly crafted gameplay. Now that’s staying power.

With the release of “StarCraft II: Wings of Liberty” a mere week away, and the anticipation reaching a breaking point, we’ve decided to geek out ourselves and launch a fact-finding mission even the series’ Terrans would appreciate. You do know what a Terran is, right? If not, you’ll find the answer (and more) as we divulge 12 interesting and weird “StarCraft” facts.

1) Koreans Fly First-Class “StarCraft”
“StarCraft” is kind of a big deal in South Korea. As a result, Korean Air branded two of its jets with “StarCraft II” art. Science has yet to prove whether flying is safer when there is a giant space marine painted on an airplane, but it can’t hurt, right?

2) Professional “StarCraft” Players Have Something in Common With Professional Athletes: They Cheat
Losing intentionally and illegally betting on games are no longer limited to actual sports, thanks to a South Korean scandal that saw nearly a dozen professional players implicated in illicit activities surrounding “StarCraft” matches. Sorry, 1919 Chicago White Sox and Pete Rose, you’ve got some nerdy Korean company.

3) “StarCraft” Is Home-Console-Unfriendly
The only home video game console to get a “StarCraft” title was the Nintendo 64, with the appropriately yet unimaginatively titled “StarCraft 64.” Besides that one tryst, the series has remained exclusive to the PC and Mac platforms. As of now there are no plans to bring “StarCraft II: Wings of Liberty” to the Xbox360, PS3 or Wii.

4) “StarCraft” Has Seen the Vast Emptiness of Space
Astronaut Daniel Barry took one giant leap for nerd-kind by bringing a copy of “StarCraft” with him into space. Reveling in the inherent irony of bringing a video game about killing evil space bugs along while you actually circle Earth in a spaceship, the developers requested the intergalactic game CD and now keep it at Blizzard HQ.

Quantum entanglement in photosynthesis and evolution

July 23rd, 2010

Recently, academic debate has been swirling around the existence of unusual quantum mechanical effects in the most ubiquitous of phenomena, including photosynthesis, the process by which organisms convert light into chemical energy. In particular, physicists have suggested that entanglement (the quantum interconnection of two or more objects like photons, electrons, or atoms that are separated in physical space) could be occurring in the photosynthetic complexes of plants, particularly in the pigment molecules, or chromophores. The quantum effects may explain why the structures are so efficient at converting light into energy — doing so at 95 percent or more.

In a paper in The Journal of Chemical Physics, which is published by the American Institute of Physics, these ideas are put to the test in a novel computer simulation of energy transport in a photosynthetic reaction center. Using the simulation, professor Shaul Mukamel and senior research associate Darius Abramavicius at the University of California, Irvine show that long-lived quantum coherence is an “essential ingredient for quantum information storage and manipulation,” according to Mukamel. It is possible between chromophores even at room temperature, he says, and it “can strongly affect the light-harvesting efficiency.”

If the existence of such effects can be substantiated experimentally, he says, this understanding of quantum energy transfer and charge separation pathways may help the design of solar cells that take their inspiration from nature.

How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved.
