Coal-based jet fuel poised for next step

A jet fuel comparable to Jet A or military JP 8, but derived from at least 50 percent bituminous coal, has successfully powered a helicopter jet engine, according to a Penn State fuel scientist.

“Because the fuel is 50 percent derived from coal, it could reduce our use of imported petroleum for this purpose by half,” says Dr. Harold H. Schobert, professor of fuel science and director of Penn State’s Energy Institute. “We have shown in tests that the mix can go to at least 75

New sensor technology detects chemical, biological, nuclear and explosive materials

Applications for homeland security, emergency planning

Engineers at the U.S. Department of Energy’s Argonne National Laboratory, using an emerging sensing technology, have developed a suite of sensors for national security applications that can quickly and effectively detect chemical, biological, nuclear and explosive materials.

“We can use this technology to detect chemical and biological agents and also to determine if a country is using its nuclear reactors to pro

Energy prices, uncertainty and energy saving by companies

Why do so many companies fail to make use of the energy-saving technologies which are available? Dutch researcher Mark Koetse used a meta-analysis of various empirical studies to assess the relevance of two possible explanations.

Meta-analysis is a research method that has been gradually gaining ground within economics since the mid-1980s. The doctoral research of Mark Koetse focused on the problems associated with this methodology. That is why in his thesis he described the ne

Objective View On Hydrogen

“Hydrogen power engineering — is energy of the future”, efforts are being undertaken in the US, Europe and Russia to implement the above postulate. We have tried to calculate the quantity of hydrogen needed to transfer to it all transport of big cities, i.e. the quantity that will be required to replace engine fuels. All calculations were based on maximum coefficients of efficiency and the most optimistic figures. The conclusions made from the obtained figures seem interesting not only for scientis

New wrinkle in the mystery of high-Tc superconductors

In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. “We are still at the beginning,” says Tonica Valla, a physicist at the U.S. Department of Energy’s Brookhaven National Laboratory, who will give a talk on his group’s latest results at the American Physical Society meeting in Baltimore, Maryland on Thursday,

Student entrepreneurs: New sensor will help guarantee freshness

Grocers, florists and even pharmacists may soon have a better way to monitor the quality of the products they get from suppliers: a sensor that will tell how long before a product spoils or passes its expiration date.

A team of University of Florida engineering students has designed and built a prototype of the new smart sensor, which can also record and wirelessly transmit information to retailers about when and where glitches occur as a product is being shipped.

“We t
