An idea from computer science known as Landauer's principle provides a useful way to think about relations between metabolic energy and the information in biological systems. Landauer's principle ...

Based on the the heat pump-organic rankine cycle, scientists in Portugal have created six different models of Carnot batteries for stationary storage. They investigated 16 different combinations of ...

Based on a Peterbilt 579 commercial semi truck, the ReVolt EREV hybrid electric semi truck promises 40% better fuel economy and more than twice the torque of a conventional, diesel-powered semi. The ...

THE cycle proposed by Dr. J. S. Haldane (NATURE, August 29, p. 326) as a standard of comparison for steam engine performance can be shown quite readily on a temperature-entropy chart, and thus be ...

Simple cycle gas turbines provide efficiency levels of around 35% to 40%. Combined cycle units boost efficiency to 60% and beyond. But another option is emerging that combines the attributes of simple ...

Sadi Carnot was a child of the Industrial Revolution. Steam power was widely used in manufacturing and mining by his birth in 1796, and the first steamboat and first steam railroad locomotive were ...
