In Sustainable Energy - without the hot air, one of my main conclusions is "electrify everything" - in particular, I recommend electric vehicles. At a recent talk, someone in the audience said, yes, maybe electric cars are now viable. But surely you couldn't electrify freight? Leaving aside two possible answers (namely 1: for local freight deliveries, electric trucks are already genuinely in use, and are manufactured by a couple of companies in the UK; 2: we could make electric freight like eletric trolley buses, using overhead lines), I thought it would be interesting to investigate, using the same model I used for cars in my book, the possibility of making long-distance freight vehicles with on-board batteries.

Providing electricity to people in countries where either the grid is not reliable, or nonexistent and unlikely ever to be built, can make a huge difference in people’s quality of life in very practical ways. We’ve written before about companies such as D.Light Design which have solar-powered replacements for kerosene lanterns , and efforts to bring small-scale solar panels to off-grid villages in Laos. Hand cranked cell phone chargers, radios and flashlights are other proven options that have received attention.

They cost around $1100 and are available at Pioneerelectronics. They use 6% less electricity that standard models. The Power consumption is 90Watts when running and just 1 Watt when not. The driver has a 30cm bass driver, the frequency is 25 to 4000Hz.

The world runs on electricity. Demand for electron power in emerging economies is often 3-4 times greater than demand for oil. Because the old model of the electricity grid does not seem adequate in meeting the new demands of the 21st century, many energy pundits argue that access to electricity is the world’s biggest strategic energy issue.

Appearing on PRI’s The Takeaway with John Hockenberry, Golden was asked how he would advise Congress and the upcoming Obama administration on the proposed U.S. multi-billion dollar auto industry bailout. He responded by unequivocally advocating the avoidance of “any further investments into the old combustion engine model” arguing that the country needs to quickly move past hybrids by leap-frogging “to an all-electric platform.”

The Tindo bus is the stuff of car-free, green, geeky dreams: It epitomizes efficient urban transportation and energy use, and to top it all off, it’s free. Our friends at EcoGeek first tipped up off to the story.

Such a capacitor gauge could become a common sight on the dashboards of the future. A capacitor can discharge and recharge far faster than a battery, making it ideal both for generating bursts of speed and for soaking up the energy collected by regenerative braking. AFS Trinity, a company based in Washington state, has turned that insight into a piece of equipment that it has fitted into an otherwise standard production model as an experiment. The result—the XH-150—was unveiled at this year's Detroit motor show.

Natural Gas and Hybrid Vehicles Lead Annual Green Rankings The natural gas-powered Honda Civic GX is once again the greenest new car sold in the United States, according to the American Council for an Energy Efficient Economy (ACEEE). The ACEEE's Green Book Online, released on February 19, places the Honda Civic GX on top for the second year in a row, followed by the Toyota Prius and Honda Civic Hybrid. Other hybrids in the top-twelve list include the Nissan Altima Hybrid in sixth place and the Toyota Camry Hybrid in tenth. The ACEEE's annual evaluation of the current model year vehicles ranks them primarily in terms of air emissions and fuel economy.

With all the talk recently of EV’s being tested in various countries and three models (Subaru R1e, Mitsubishi iMIEV, Nissan Denki Cube) potentially arriving in the US in just a few years, it’s worth revisiting once more the notion of how well such a product would be received here. My longtime position has been that if you make even minimally reasonable assumptions about the vehicles–they’re safe, they’re as efficient as one would expect a small, all-electric vehicle to be, they’re affordable, and they don’t have any weird “gotcha” details–they’ll find millions of happy owners.

A new approach to selling and recharging electric cars could overcome some of the basic issues that have kept them from being widely adopted. A startup called Project Better Place, which had the largest of any venture-funding round in 2007, raising $200 million, recently announced plans to install recharging infrastructure in Israel and Denmark and to sell electric cars using a business model much like that used today with cell phones.

Here's a nice example of the vital distinction between consumption and efficiency. If I told you that a company was about to introduce a new car model that was expected to average 56 miles per gallon, and that it was going to be so cheap that nearly anyone could afford one, that would sound like great news, wouldn't it? Perhaps it depends on the context in which that car is introduced, and our assumptions about what it will displace. The car in question is Tata Motors' eagerly-awaited "1-Lakh" car--referring to its 100,000 Rupees price equating to $2546 at yesterday's exchange rate--and the target market is millions of Indians who haven't been able to afford a car yet. Even at an expected efficiency of 56 mpg, though, the Nano, to give its proper name, will create incremental consumption of petroleum products and new greenhouse gases emissions.

It's been awhile since we heard anything about the HumanCar, but it looks like the Flintstones-inspired vehicle is now rapidly becoming a reality, with it finally getting a price, release date and a even slightly sleeker new look. Apparently now more specifically known as the Imagine LMV, the vehicle will appropriately be available this coming Earth Day (April 22nd), when it'll set you back a hefty $15,000 for the "base" model. For that price you'll apparently get a top speed of 30 mph from the vehicle's dual electric motors and, most importantly, "variable human power input," which should soon make you the most popular member of your car pool group. If that's not enough luxury for you, you'll also apparently be add various navigation and internet options, iPod connectivity, and various biometric devices to see just how much of a workout you're getting.

After working on the air powered car concept for the past 15 years French engineer Guy Negre is about to bring this revolutionary vehicle to the masses thanks to a contract with India’s main car manufacturer; Tata Motors. Not only is this the worlds cleanest car but it is also functional with MDI offering various designs to suite your life style. The Pickup, Van, Taxi, Mini CAT, and family car models will all be made available for less than $15,000.

Qualcomm has developed a new energy-efficient display technology based on lightwave interference. Their technology, an interferometric modulator (IMOD) display, works by setting up interference patterns in light. If light reflects off two surfaces that are within one light wavelength apart, a destructive interference pattern sets up that cancels out that wavelength of light.

We examined the world production of 57 minerals reported in the database of the United States Geological Survey (USGS). Of these, we found 11 cases where production has clearly peaked and is now declining. Several more may be peaking or be close to peaking. Fitting the production curve with a logistic function we see that, in most cases, the ultimate amount extrapolated from the fitting corresponds well to the amount obtained summing the cumulative production so far and the reserves estimated by the USGS. These results are a clear indication that the Hubbert model is valid for the worldwide production of minerals and not just for regional cases. It strongly supports the concept that “Peak oil” is just one of several cases of worldwide peaking and decline of a depletable resource. Many more mineral resources may peak worldwide and start their decline in the near future.
