Graphene batteries that never die
Graphene batteries that never die
Graphene is a cool substance – and this particular discovery makes it even more cool: A sheet of graphene constantly produces energy. See, graphene vibrates at an atomic level. But these vibrations aren’t just random: an impulse creates waves in the sheet, which can be measured in terms of how much the carbon atoms vibrate.
That makes plenty of use cases once the technology ripens. Organic batteries that could power medical implants, batteries that don’t die, really tiny batteries for chips or tags…
…and all of that without setting off a metal detector. As we move into an age of organic technology, that might be a worrying thought for security professionals.
Oh, and one nasty incorrect statement in the linked article: This discovery doesn’t make graphene a source of unlimited free energy production. Rather, it is a conversion of energy input from outside the system (such as temperature difference that starts the ripples) to inside the system (the wave movement of the atoms in the sheet). But for all practical purposes, as long as we’re on Earth, these inputs happen often enough to keep new waves going – and so you get what seems to be an unlimited source of energy.

Half the universe’s missing matter has just been finally found

Half the universe’s missing matter has just been finally found
The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe – protons, neutrons and electrons – unaccounted for by previous observations of stars, galaxies and other bright objects in space.
