All it takes is a lot of duct tape, some ducting, PVC pipe, 50 gallon drum, a pile of wood and an old furnace to beat today’s high gas prices.
A man identified only as Bob contributed this story to Coast to Coast, saying the owner told him the wood burning oven catches combustible fuels from wood coals which condenses any moisture. The dried fumes are fed to the engine, and it […]
General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion.
The undisclosed equity share aims to contribute to joint research and development along with technology exchange, plant siting, and rapid commercialization of cellulosic ethanol technology and infrastructure. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January.
Americans are feeling the pain of high gas prices; I just paid $4.20 a gallon at the pump in northern California. Needless to say, the presidential candidates are scrambling to be the savior of the gas guzzling voter. Both McCain and Clinton support suspending federal excise tax on gasoline and diesel fuel over the summer, but is this the right solution? Barack Obama disagrees, and I can’t help but think this is a band-aid solution.
The federal excise tax on gasoline was first implemented in 1932, although the states began taxing fuel in 1919. It is estimated that suspending this tax, as proposed by Clinto and McCain, would result in a loss of revenue of nine billion dollars for the Highway Trust Fund, which is used for interstate maintenance. McCain says he would shift revenue from other sources, and Clinton proposes enacting windfall-profits tax on big oil companies to make up for the loss. Both candidates are making Obama look like the bad guy for not wanting to save consumers 18 cents per gallon, but would this temporary suspension of the federal excise tax on gasoline really be the catalyst to change our current oil dependency and the harm it causes to the environment?
Residents of Washington, Oregon, and Idaho are outpacing the national average decline in gas consumption, according to a new report by the Sightline Instutute.
In the last 8 years, residents of these states have cut back by about a gallon per week, for a total gas consumption reduction of 11%. In the Pacific Northwest, gas usage has fallen to its lowest level since 1966, while CO2 emissions from gasoline have fallen by six-tenths of a ton per capita since 1999.
By heating cellulosic plant material to between 750 and 1,100 degrees Fahrenheit in the presence of a catalyst, then quickly cooling it, the team of graduate students led by associate professor George W. Huber was able to produce a mixture of hydrocarbons identical to gasoline in less than two minutes. The conversion is a relatively simple, one-step process that could create biogasoline for as little as $1 per gallon.
Range Fuels says their facility will break down any type of plant material (eg agricultural waste or wood chips) by a two-step thermochemical process. This differs from competing methods of producing cellulosic ethanol, which involve breakdown of plant material with heat and/or acid, and treating it with costly ($0.50/gallon) enzymes.
This week’s report from Oak Ridge National Laboratory, which evaluated the impact of a substantial increase in PHEV ownership, found that nighttime charging of PHEV’s would not increase electricity demand over baseline levels. In other words, no (or very few) new power plants would need to be constructed if plug-in owners only charged their vehicles at night.
Not everyone is waiting until 2010 to get their first plug-in hybrid. As I reported previously, Hybrids Plus out of Boulder, CO, is offering conversions for the Toyota Prius and Ford Escape hybrids, turning them into 100 MPG+ superstars.
I’ve collected a little more background on Prius hybrid hacks, and a few more resources. Check out this video, which should give you a good feeling for what getting 100 MPG would be like:
55 MPG isn’t good enough for you? Then try adding a plug to your hybrid.
The electric-car company ZAP, in conjunction with Hybrids Plus, has announced it will offer plug-in hybrid conversions for the Toyota Prius and the Ford Escape Hybrid:
Hybrid vehicles retrofitted with systems from Hybrids Plus of Boulder, Colorado can achieve a significantly greater fuel economy. In tests these systems increased hybrid fuel economy up to 120 miles per gallon in the city and up to 90 mpg on the highway. The cost for the conversion ranges from $24,000 to $36,000 depending on the vehicle and size of battery pack.
