A battery can hold a lot of energy, but it takes a long time to charge it. A capacitor can be charged very quickly, but doesn't hold a comparable amount of energy.
A graphene supercharger is the best of both: it takes just seconds to charge, yet stores a lot of energy. Imagine being able to charge your spent laptop or phone battery in 30 seconds, and your electric car in a few minutes. Also, unlike batteries, Graphene supercapacitors are non-toxic.
The Nobel Prize was awarded to the inventors of Graphene in 2010. Wikipedia defines Graphene as a "substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams."

California assemblyman Jim Cooper (D-9th) has copy-pasted New York assemblyman Matthew Titone’s (D-61st) insane, reality-denying bill that bans companies from selling smartphones with working crypto on them, introducing nearly identical measures in the California legislature.
Trumpscript — a python variant — only allows numbers over 1,000,000; has no import statements (all declarations must be homegrown); only has integers because floating-point numbers are un-American (America never does anything halfway); only allows popular words and the names of politicians as variable names; limits error messages to direct Trump quotes; and requires that […]
“Radical ecology” has come to mean a kind of left-wing back-to-the-landism that throws off consumer culture and mass production for a pastoral low-tech lifestyle. But as the brilliant science journalist and Marxist Leigh Phillips writes in Austerity Ecology & the Collapse-Porn Addicts: A Defence Of Growth, Progress, Industry And Stuff, if the left has a future, it has to reclaim its Promethean commitment to elevating every human being to a condition of luxurious, material abundance and leisure through technological progress.
Remember back to the time when people thought java was just a hip way to talk about coffee? Or you vaguely remembered from geography class that it’s an island in the South Pacific? We’ve come a long way since then and now that we’ve rocket blasted into the tech future, you’re going to need to […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
