In the early years of the nineteenth century, steam engines were at work in a variety of practical uses. However, they were still imperfect in many ways. One particular problem were the boilers, that ...

E-bikes and motorcycles are great, but what if there were another way to get moving? What if there were a motor that didn't require the combustion of Odin's juice to get moving? Well, there are plenty ...

Nov. 30 -- In order to develop more fuel-efficient, environmentally friendly power sources of the future, some researchers are turning to a technology of the past. Several companies and developers ...

One of the basic truths learned in college thermodynamics courses is that no heat-activated cycle can be devised that is more efficient than a Carnot cycle operating between the same temperature ...

Dean Kamen – the multimillionaire inventor behind the Segway personal transporter – is well down the road in the development of a new bike that combines electric power and a radical generator which ...

Instead of relying on the expansion of high-pressure steam, the Stirling engine is a closed system with a working gas, usually air, that generates power by having one part of the engine cycle ...

Have you ever imagined a bike powered not by gasoline or electricity, but by the simple act of heating and cooling air? It might sound like something out of a science fiction novel, but the concept is ...
