Physicists in the Netherlands have built a heat engine that might be the tiniest ever created. Based on “piezoresistive” silicon, and smaller than a typical biological cell, the engine could find ...

Nelson Ireson June 6, 2008 Comment Now! Novel technologies to improve the efficiency of existing vehicles and combustion processes are the quickest route to improved fuel mileage. Hybrid cars are ...

The model Stirling engine is a staple of novelty catalogues, and we daresay that were it not for their high price there might be more than one Hackaday reader or writer who might own one. All is not ...

The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...

Another day, another means of converting waste heat into something decidedly non-wasteful. This one comes to us from the folks at Cyclone, whose self-starting Waste Heat Engine can apparently be ...

February 13, 2009 Technology capable of generating electricity by extracting energy from heat that is otherwise just wasted is a fairly new branch of renewable technology. A typical co-generation ...

image: Engineers at MIT and NREL have developed a heat engine with no moving parts that is as efficient as a steam turbine. view more CAMBRIDGE, MA -- Engineers at MIT and the National Renewable ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...

Research from The University of Manchester has thrown new light on the use of miniaturised 'heat engines' that could one day help power nanoscale machines like quantum computers. Heat engines are ...

As the world battles rising inflation, a cost-of-living crisis, climate change and more, it’s clear that the fossil-fueled status quo is not working. Fossil fuels may have seemed like the crutch we ...
