Giant ‘sand battery’ holds a week’s heat for a whole town

A new industrial-scale ‘sand battery’ has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant … Continue reading Giant ‘sand battery’ holds a week’s heat for a whole town

Diamond nanomembranes make electronics 10x cooler, 5x faster to charge

Diamond is more than a pretty face – it knows how to keep its cool, thanks to its excellent thermal conductivity. Now, engineers at Fraunhofer have taken advantage of that, using ultra-thin diamond membranes to drastically cool electronic components an… Continue reading Diamond nanomembranes make electronics 10x cooler, 5x faster to charge

Heat caught moving like sound waves in a superfluid for first time

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.Continue ReadingCategory: Physics, ScienceTags: Heat… Continue reading Heat caught moving like sound waves in a superfluid for first time

Experimental system uses microwaves to cook crop pests in soil

Just like any other organisms, crop-destroying soil microbes die if they get too hot. With that fact in mind, scientists have developed a new system in which soil-heating microwaves are used to kill such pests. The technology could one day replace the … Continue reading Experimental system uses microwaves to cook crop pests in soil
