Hydrogen fuel cell bikes - Biofuel Debate Forum - Bio Fuel, BioDiesel, Bio Oil & Bio Ethanol Discussion
fuelcell bikes
-
Several companies in the past have showcased their plans to use hydrogen fuel cell technology to power a bicycle. Recently, Chinese company Pearl Hydrogen became the latest company to showcase the idea, at a recent technology convention in Shanghaimart. The 20” wheel prototype weighs 32kg and is powered by a PEM fuel cell and brushless electric motor. The top speed is 25km/hour and the 600L twin cylinder fuel cells have a maximum range of 100km. Some trial orders have already been placed for 20,000 Yuan (about US$2,650). The company is optimistic that their hydrogen bike will be successful enough to begin mass producing bikes for the mainstream Chinese market, for a more affordable 4,000 Yuan (US$530). There are no current plans to ship the fuel cell bicycles overseas.

New report reveals real price of agrofuels in Latin America
Brussels (Belgium) / Porto Alegre (Brazil) / Montevideo (Uruguay), 10 September 2008 - The rapid development of agrofuels in Latin America looks set to increase big business profits but it is not benefiting local people, according to a new report released today September 10 by Friends of the Earth International. [1] The report is published one day before key MEPs vote on the future demand for agrofuels in Europe.
The new report - 'Fuelling Destruction in Latin America' - looks at current and proposed developments in a number of Southern and Central American countries, all of which are scaling up agrofuel production at alarming rates to meet domestic and, increasingly, export demand to supply diesel and gasoline to Europe and the US.
The report states that increasing the amount of land destined to grow crops for agrofuels means increasing deforestation and wildlife destruction, increased land conflicts, eviction of rural people, poor working conditions and environmental pollution.
Paul de Clerck, Corporates Campaigner for Friends of the Earth International, said: "Growing agrofuels on a large scale in Latin America is totally unsustainable and it is not helping ordinary people or the environment. More agrofuels means that agribusiness companies, financial speculators and big landowners will make vast profits at the expense of people and the environment".
The report highlights that:

GreenShift Corporation - Technologies - Animal Fat Extraction
About 100 million pigs, 35 million cattle, 1.6 billion turkeys and 8 billion chickens are slaughtered and processed each year in the United States. The USDA requires facilities that process these meats to use large volumes of clean water to continuously rinse the meats as they are cut and packaged. These large volumes of water contain extremely high levels of protein and fat that are later removed by using conventional but highly efficient wastewater processing methods. The result of these processes is a cleansed wastewater and a co

hile the global debate rages on whether the biofuel revolution is causing imbalances in food security systems and increasing the greenhouse gas emissions the ‘smart’ biofuel crops developed, utilized and promoted by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh, ensure energy and environmental security.
According to Dr William Dar, Director General of ICRISAT, the time has come to ensure that only smart biofuel crops are developed and utilized so that they can link poor dryland farmers with the biofuel market, without compromising on their food security, or causing environmental damage.

Roundup: The “biodiesel miracle,” bargain-priced “green” gasoline and a sweet new biofuel source
Jeremy Jacquot | April 26th, 2008 | 3 Comments
Here are a few of the latest startups we’ve spotted promising cheaper, easier ways to turn organic material into fuel:
Minnesota undergraduates use “Mcgyan Process” to produce cheap biodiesel — Ever Cat Fuels claims its proprietary technology, dubbed the “Mcgyan Process” (after the names of the inventors McNeff, Gyberg and Yan), can convert most feedstocks into biodiesel without producing too must waste or consuming much water — a technology loftily deemed “one of modern day’s great discoveries” by Augsburg President Paul Pribbenow. A highly efficient metal oxide catalyst accelerates the continuous, or “flow,” process, in a fixed bed (tubelike) reactor.
Unlike conventional biodiesel production, which can take several hours to complete and often produces waste, the Mcgyan Process only takes a few seconds to complete. Ever Cat Fuels is building a $5 million plant in Isanti, Minnesota, that could eventually generate over 3 million gallons of biodiesel each year. The ambitious start-up is eyeing algae as its first potential source of feedstock oils.
UMass researchers develop cheaper, “green” gasoline — No, that’s not a typo: A team of researchers at UMass, Amherst, led by chemical engineer George Huber, has developed a new process to refine hydrocarbons from cellulose. This “green” petroleum can be produced from a variety of biomass sources, including feed stocks, wood scraps and corn husks, and, because it’s made of hydrocarbons, can be pumped directly into existing car engines. To produce this gasoline variant, Huber heats cellulose in the presence of solid catalysts and rapidly cools the products — leaving behind a liquid containing most of the compounds found in gasoline, such as toluene and naphthalene. It needs only a moderate amount of heat and takes less than 2 minutes to complete. Once the process hits a 100% yield — it’s at 50% now — Huber estimates that it coul

According to our inventive process the advantages of alkaline transesterification of triglycerides and esterification and transesterification of triglycerides with homogenous catalyst were joined together. This is reached by carrying out conversion of oils into one or maybe two steps. (See enclosed scheme.)
