A forthcoming article in The Quarterly Review of Biology provides the basis for an argument against using the Gibbs free energy equation to accurately determine the thermodynamics of microbial growth. Microbial growth is a biological process that has been previously treated as a chemical reaction operating in accord with the Gibbs free energy equation, developed during the 1870s. The heat of yeast growth was the first to be measured by direct calorimetry, in 1856. However, the full...

Researchers try to get the temperature-independent energy spectrum of some materials for obtaining all their thermodynamic properties from their experimental heat capacities alone. However, measurements are made at finite temperatures in practice, such as with phonon spectra obtained by inelastic neutron scattering, so it is very difficult to obtain a T-independent energy spectrum for any real material. One promising method to obtain such a spectrum is to solve the so-called specific...

CHICAGO, May 4, 2011 /PRNewswire/ -- Enlighten Media Inc. has released a revealing new audio course that shows how to use magnetic motors to make unlimited energy--for free. The thought-provoking audio book by the Chicago-based company compares magnetic motors and engines that run on water to current forms of polluting and renewable sources of energy such as coal, oil, nuclear power, wind, and solar. According to Jody Bruce, who authored the audio course, energy can be made for free...

How to get wind turbines to work harderHow much usable energy do wind turbines produce? It is a question that perplexes engineers and frustrates potential users, especially on windless days. A study published this month in the International Journal of Exergy provides a formula for answering this vexing question.Abolfazl Ahmadi and Mehdi Ali Ehyaei of the Department of Mechanical Engineering, at Iran University of Science and Technology-Arak Branch, in Arak, have investigated the "exergy" of...

Tapping industrial waste heat could reduce fossil fuel demands in the short term and improve efficiency of countless manufacturing processes, according to scientists in Japan writing in the International Journal of Exergy. Lihua Zhang and Tomohiro Akiyama of Hokkaido University, Sapporo, explain that heat waste from industrial processes, such as combustion and electricity generation is sometimes of low energy and diffuse. Capturing this low-quality heat for re-use elsewhere on an industrial...

DUBLIN (Reuters) - An Irish technology firm issued a challenge to the world's scientific community on Friday to give its verdict on technology it says smashes one of the basic laws of physics by producing "free energy." Dublin-based Steorn said it had placed an advertisement in The Economist magazine seeking 12 top physicists to examine the technology -- based on the interaction of magnetic fields -- and publish their results. "We fully accept there is going to be cynicism...
