Hitting the Books: Why America once leaded its gasoline
Automakers have been fighting to eliminate Engine knock since the days of the Model T. Their initial attempts to fix it, as University of Manitoba's Professor Vaclav Smil explains in "Invention and Innovation," went over like a lead balloon.
Study suggests EVs really are cleaner than gas-powered cars over their lifespan
A new study compares the life-cycle of EVs with gas-guzzlers in four of the biggest car markets in the world.
Mazda's engine breakthrough promises big fuel efficiency gains
Mazda has made the announcement car manufacturers have been working towards for years: it's releasing the first commercial compression-ignition gasoline engine. Dubbed SkyActiv-X, the engine will be available in 2019 and promises up to 20-30% more engine efficiency than the current SkyActiv-G, and up to 45% more than Mazda's 2008 petrol engine. Current gasoline engines rely on a spark plug to ignite their air-fuel mix. The SkyActiv-X will ignite the air-fuel mix spark-free through compression, like a diesel engine. This, according to the Japanese manufacturer, combines the advantages of petrol and diesel engines to achieve "outstanding" environmental and power performance.
Infiniti's latest engine is a last hurrah for gas-powered cars
Hybrid and pure electric cars may be the future of transportation, but Nissan's Infiniti badge has found a way to make the most out of gas engines while they're still relevant. When the next-generation QX50 crossover arrives in 2017, it'll carry the first-ever production variable compression turbo (VC-T) engine -- a technology that promises to dramatically improve fuel efficiency without compromising on performance. By automatically adjusting the height the engine's pistons reach, the VC-T motor can optimize its compression ratio for the task at hand. It'll lower the ratio if you're mashing the throttle (to prevent premature detonation and make the most of the turbo), but raise it when you're putting around town and need to wring out better mileage.
Honda: we won't be able to sell gas-only engines in China by 2025
We're fortunate that most auto companies are embracing an alternate energy future, with all manner of electric cars hitting the streets lately -- and that's not to mention hydrogen-powered vehicles like the Toyota Mirai and Honda's Clarity. The latter manufacturer just gave a pretty frank appraisal of its future selling gasoline-powered vehicles, and it feels like those days will be numbered sooner than we might expect, at least in China. In an interview with Wards Auto, Honda's chief technology strategy officer Keiji Ohtsu predicted that by 2025, Honda wouldn't be selling any cars with traditional internal combustion engines in the world's most populous country.
Volkswagen also lied about its gas-powered cars
Volkswagen admitted in September that it used defeat devices aimed at fooling emissions tests in 11 million of its diesel vehicles -- but now its gasoline models are implicated in the scandal as well. On Tuesday, Volkswagen reported that it understated the level of carbon dioxide emissions of about 800,000 vehicles, including gasoline-powered models. This is the first confirmation that some of Volkswagen's gasoline-run vehicles do in fact exceed carbon dioxide emissions. The company didn't provide details in today's revelation, but it said the conclusion comes after conducting internal emissions tests.
Jay Leno's Chevy Volt still has original tank of gas, 11,000 miles later
What daily driver do you pick when you're rockin' a warehouse with over a hundred enviable whips? Well, if you happen to be a famous comedian named Jay Leno, apparently it's the Chevy Volt. Since procuring the plug-in chariot last year, the late night star has "yet to put gas in it," despite accumulating over 11,000 miles driving to and from what we'll assume is The Tonight Show. Not all of that has been gasoline-free automotive bliss, as Leno's exceeded the car's electric 40-ish mile range more than a few times, burning through around half of the vehicle's original tank. At that rate, the Volt will need refueling by this time next year -- or not, barring any further timeslot kerfuffles.
Wasteland Diaries: Apocalypse DIY
A few weeks back I did a piece on crafting, covering the basics of Fallen Earth's crafting system. In this article I want to focus on the early part of a crafter's career. If you only play one clone, I strongly suggest you make that clone a crafter. If you are an altaholic like I am, you should have a dedicated crafter, and that dedicated crafter should have his Social skill maxed out (eventually). If you don't have a crafter and you have an empty character slot, you need to create one post-haste. It's a little extra work that will pay off a lot later. In Fallen Earth, if you put in the time, you can make everything. If your crafter and your main happen to be the same, be sure to grab every resource within reach while you run missions. If you find a good spot, mark it with a waypoint (ALT+P) for future reference. Scavenging profusely will help keep you from being perpetually broke. If you have a dedicated crafter, don't bother running missions with him; just harvest and craft. He should level slowly but surely by simply harvesting and crafting. Send all of the materials that your other clone(s) harvest if you have the vault space. That covers the basics. The road to self-sufficiency continues after the cut.
Nissan Leaf blessed with 99MPG 'equivalent' sticker, roundtable arguments ensue
Cue the pundits. Nissan's incoming Leaf has just nabbed an official EPA sticker, with a mind-melting 99MPG "equivalent" rating set to grace every single window. That'll undoubtedly catch eyes, but it's also likely to spur a huge debate on what "miles per gallon" truly means when you're throwing a battery into the mix. We actually had the pleasure of driving one ourselves late last month, but we weren't able to take off on any extended joyrides to really put MPG claims to the test. At any rate, the 99 rating breaks down to 106MPG in the city and 92MPG on the highway, but there's quite a bit of fuzzy math here that gas guzzlers aren't accustomed to considering. Nissan claims that the EPA uses a formula where 33.7 kWhs are equivalent to one gallon of gasoline energy, and that the entity also found the Leaf's efficiency to be 3.4 miles per kWh. Given that the car has a 24 kWh battery pack and can go 73 miles officially, then the EPA says it could theoretically go 99 miles if it had a 33.7 kWh pack. Still, the Leaf has to await its other label from the FTC, but it's apt to show a range of 96 to 110 miles of range. Head on past the break for the full presser.
Segway sales hit all time high, thanks OPEC!
We get that rising gas prices are putting folks in a world of hurt, but has it really gotten so bad that we're resorting to losing our dignity riding Segways? According to a recent writeup in The Wall Street Journal, "sales at Segway Inc. have risen to an all-time high," and CEO Jim Norrod fully expects sales this quarter to "jump 50% from a year earlier." Not surprisingly, many of its new customers are universities and public service divisions who are replacing traditional vehicles with the all-electric scooters, but we still get the impression that individuals are steering clear due to its remarkably high price and laughable design. At least, that's what we'll continue to tell ourselves.
Chicago Shell stations trialing biometric payment systems
Simply swiping one's credit / debit card at the pump is probably sufficient for the bulk of us, but for certain Shell customers in Chicago, paying for gasoline is getting even quicker. Ten stations in the Windy City are trialing biometric payment systems -- crafted by California-based Pay By Touch, which has units in a variety of other stores already -- that enable customers to scan their fingerprints, fill up and cruise off. The machines are purportedly linked directly to checking or credit card accounts, which customers initiate at the store or online. Unfortunately, we've no idea if Shell plans on expanding this to other locales after the pilot program has concluded, but Chris Susse, Shell's manager of global refueling innovations (nice title, eh?) did note that he hoped the initiative would increase customer loyalty at the very least.
Hydrogen separator could power fuel cells from city gas
We've seen power hacks that allow hybrid vehicles to energize your domicile, but even that isn't enough to change how entire cities receive electricity. Now, however, the Japan Fine Ceramics Center (JFCC) has collaborated with Noritake Co. and a few other firms to develop "a high-performance hydrogen separation membrane made from ceramic materials" that can purportedly "attach directly to a gas pipeline to supply hydrogen for fuel cells using city gas as the source." Additionally, the the reaction to generate hydrogen can be carried out at a temperature of around "300-degrees lower than normal," and while current estimations are suggesting that cities won't be powered via this method until closer to 2020, there's always the option for a gigantic solar field to fill the void in the time being.

Costco sells gasoline powered PS3
California is one of our great states that stays abreast of environmental issues and presents propositions to ensure a greener society. One proposition in particular, promotes clean drinking water with legislation to keep toxic chemicals out of consumer products. Well apparently, someone forgot to inform Costco that the PS3 console doesn't use gasoline and is packaged as a solid, which makes it impossible to consume as a liquid or get mixed in with the drinking water. According to this advertisement, Costco has included a reference to California's Proposition 65 in order to inform any prospective PS3 buyer that the console could be toxic because of its use of gasoline, a highly flammable (and not very tasty) fossil fuel. We've looked (twice) and haven't yet found a gas tank or opening marked "fuel" on our PS3. Now, we suppose there might be some funky materials under that sleek hood, but even so, the PS3 doesn't appeal to us as being edible. Anyone else find a gas tank included in their PS3, or dreamt of a PS3 between two slices of rye with lettuce? Please, do tell.[Via digg]
Software patch could boost MPG in gas-powered vehicles
No doubt, we've seen more than a few sensational sounding gizmos aiming to provide (nearly) limitless power and create energy out of thin air, but a simple software patch could enable the vast majority of the world that's still stuck in gasoline-powered vehicles to get better gas mileage. John Kessels at the University of Eindhoven has partnered with Ford to develop software to improve engine performance and save "up to 2.6-percent" in terms of miles per gallon. Quite simply, the patch dynamically switches the dynamo, (which charges the car battery) on and off when it is "particularly inefficient for the engine to power it, thus improving the overall efficiency of the engine." Mr. Kessels even stated that "a simple cable and a software upgrade" was all that would be necessary to boost MPG, and thankfully it's not exclusive to Ford motors. Notably, a fuel savings closer to six-percent could likely be achieved if a "powerful starter motor" was installed to allow your engine to cut off entirely and restart quickly in between long traffic jams, but both methods have a good bit of testing to go through before being deemed non-abrasive to batteries and engine components. But hey, there's nothing a firmware upgrade can't fix, right?
MIT gasoline / ethanol engine to up gas mileage by "30 percent"
Anyone with enough coin to not concern themselves with fuel prices anyway can throw down $100,000 (or more) for an uber-green Tesla Roadster, or you can tack a few extra grand onto the price of your next vehicle to ensure it has some sort of hybrid engine underneath the hood, but MIT researchers are developing yet another alternative to our oh-so-troublesome fuel dilemma without looking to fuel cells. The gasoline / ethanol prototype is about "half the size" of a conventional gas engine, and would only add "about $1,000" to the price of a vehicle -- much less than current battery / gasoline options. The gasoline and ethanol are housed in separate tanks, with the ethanol "suppressing the spontaneous combustion inside the cylinder," allowing for a "higher compression ratio" and a "30 percent increase" in overall gas mileage. Ford is currently testing the system with Ethanol Boosting Systems, and while we're unsure how these engineering minds will solve the problem of double-pumping each time you need a fill up, they're reportedly working hard to "minimize any inconvenience to the driver."
EnerAge plans to power your laptop with a hydrocarbon fuel cell
If all goes well for fuel cell designer EnerAge, you may soon be able to fill up your laptop at the same time that you fill up your car's gas tank. CNET is reporting that by early 2007, the Los Angeles-area company claims that it will demo a 25-watt fuel cell that will keep your laptop juiced. While we've already seen a few fuel cell hopefuls, this new one is potentially among the most innovative. EnerAge's fuel cell allegedly will burn any hydrocarbon fuel, including methane, butane, methanol or ethanol -- so it would seem that burning diesel or gasoline is within the realm of possibility as well. While there have been countless previous attempts at fuel cells, EnerAge's design is a "direct oxidation fuel cell," which CNET explains as such: "It mixes air with a hydrocarbon. When the materials come in contact with the membrane, electrons are released. The reaction also results in byproducts like water and CO2." However, there still remains a huge engineering puzzle to get around, which is that the fuel cell itself can reach temperatures of as high as 600 degrees Celsius (that's 1,112 degrees Fahrenheit). Yikes. And let's not forget the carbon dioxide factor -- exactly what we're trying to get rid of from automobile and coal emissions (to name a couple). As you can imagine, we're skeptical at best, but any solution that might enable increasingly plugless computing is worthy of a second glance by us.
