It may be a little late for April Fool’s, but your skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the flow of entropy and heat in, it was believed, any situation. Specifically, researchers from three universities theoretically proposed then demonstrated that a nanoparticle in a state of thermal non-equilibrium does not always behave as larger particles might under the same conditions, with implications for various fields of research.
Some inventions are born of necessity while others arrive as a result of an individual having a Eureka!
moment. The Kuru-Kuru Nabe is, to some degree, a mixture of both. The name is Japanese for "Round-Round Pot" and is highly descriptive. The Kuru-Kuru Nabe is, in essence, a self-stirring saucepan, and it was invented by a humble Japanese dentist.
When most of us think of sunlight being used to generate power, we likely picture photovoltaic cells. Concentrated solar power plants
however, use lenses or mirrors to heat fluid – such as synthetic oil – which in turn is used to generate high-pressure steam to drive a conventional turbine. A new experimental solar steam generation power plant that opened last week in southern Spain is aiming to improve on the efficiency of existing systems by using water as the direct working fluid and incorporating novel methods for storing the energy, so it can be dispensed even on cloudy days or at night.
Remember that zany Irish company Steorn
, who claimed to have built a working perpetual motion machine that could produce clean, free energy out of a few magnets and some plastic discs? Well, they're back again. Undeterred by the fact that their own hand-picked jury of scientific judges unanimously agreed that the technology didn't work
, Steorn has put its Orbo perpetual motion machine out for public display, and set up web feeds through which you can watch the thing in motion. But the demonstration has failed to impress critics, and for good reasons.
When the promoters of the HH2 Hydrogen Generator Clean Air Combustion System made an appearance at last year’s LA Auto Show they attracted their fair share of skepticism. Hardly surprising given their claims of boosting the horsepower, performance, and mileage of existing vehicles through the addition of an aftermarket device that mixes hydrogen and oxygen extracted from water with existing fuel. But the naysayers haven’t discouraged the system’s developers as they are fronting up to the LA Auto Show again this year with even loftier claims thanks to improvements to their system.
