Filed under: Green , Tech , Ford Ford has yet to release its first EcoBoost engines but is reportedly already hard at work on the technology's next phase. Rumors indicate that the new engine technology is codenamed Bobcat and uses small amounts of ethanol injection to improve power and reduce emissions. Ethanol carries a very high octane rating, which allows an engine to be tuned for more power. An engine with ethanol injection can run a much higher compression ratio along with a small turbocharger as the ethanol would be injected directly into the engine's combustion chamber, thereby eliminating precompression, which is more commonly referred to as knock and can be extremely hazardous to your engine's health. The alcohol injection would be performed on an entirely different fuel injection system as the gasoline, complete with its own fuel tank. It would have to be closely metered, but should only need refilled once every few months since the amount used would be so small. Early...

Filed under: Green , Tech Jon Markman at MSN Money doesn't hold back when he says "Corn-based ethanol production is sure to go down as one of the greatest mistakes ever in U.S. energy policy." It's even more provoking when he writes "replacing fossil fuels with corn-based ethanol would double greenhouse gas emissions over the next three decades. The studies show that switchgrass, an alternative to ethanol that's more weed than plant, would boost emissions by 50%." The problem isn't with the cars, the problem is with what it takes to grow the biofuel in the first place. Clearing the land, harvesting, and refining the crops, plus the loss of forest and wild lands and habitats, amounts to creating a carbon footprint worse than fossil fuels. According to the Science article which, admittedly, posits an extreme scenario, it would take 423 years to even out the carbon debt if Indonesia's peat lands were converted to palm oil fields. The research is starting...

Filed under: Car Buying , Hybrids/Alternative , Green , Tech , GM In the fuel economy and future tech debate, the hybrid vs. diesel vs. hydrogen fuel cells vs. smaller cars and smaller engines always provokes a fair bit of discussion among Autoblog commentators. At this point, no one yet knows what's going to win since nobody knows how the volatile mix of products, timelines, prices, regulations, legislation, state standards, and gas prices will ultimately pan out. Bob Lutz's prediction is that diesels, at least as far as the US is concerned, won't be much of a factor. His reasoning is simple: "I think customers are going to say, 'Wait a minute. At equal fuel prices I'm paying $4,000 more for this." Unlike many countries in Europe, the US offers no incentive for people to buy diesels. In the States the price of a diesel vehicle is often more than $1,000 higher than that of a gasoline-engined car, and diesel fuel is just as expensive as gas (throughout California...

Filed under: Economy , Green , Tech Robert Zubrin thinks so. Zubrin is an aerospace engineer and long-time advocate of manned missions to Mars. While going to Mars is a highly dubious proposition given the issues we need to deal with on our planet right now, making all gasoline engines flex-fuel capable as Zubrin promotes in his new book is probably a very good idea. The incremental cost of flex-fuel capability is only about $100 per vehicle and that would provide the ability to use any alcohol fuel including methanol and butanol. The corn ethanol that we use today will make little if any dent in our oil imports. Cellulosic ethanol, methanol and butanol do hold a lot of promise, though. Glenn Reynolds of Instapundit and his wife, Helen Smith, have an interesting interview with Zubrin on their podcast that's worth a listen. Some of Zubrin's arguments for using alcohol fuels are a bit over simplistic and ignore some of the pitfalls associated with them. That includes draining fields...
