Electric vehicles. Battery reboot
Graphene, supercapacitors, static energy, and your cat as power station
Today, our electric cars (and electric equipment in general) are powered by lithium-ion chemical batteries. In future, we may speculate, that supercapacitors will become the most popular energy carriers.
Supercapacitors are a type of power units which store energy in electric fields. They charge and discharge very fast. They have the same properties as the fur of your cat in winter: sometimes you may get an electric shock when touching it.
The article discusses how li-ion batteries and supercapacitors (ultracapacitors) work. It explains the nature of static electricity. It mentions the Chariot Motors Company and its high-tech buses. It touches upon the possible contribution of graphene material to the automotive business. Finally, it admires the engineering though behind the Pininfarina-designed HKG H600 concept-car.
This video is a popular science author-narrated story about static electricity and its application in the contemporary world. The original story was published in 2019 and may contain some outdated data. The video is full of curious insights, interesting facts, science trivia, and electric shocks (joke).
Also, I ask for your forgiveness and understanding each time I mispronounce names, terms, and other tricky words.
Curious fact. At the beginning of the video, you see how sunbeams exert electromagnetic force on in-car dust making it... kinda statically charged? First I thought this ruined the video, but now... the lazy float of dust through the "electrified" air serves as a perfect illustration to what I'm talking about!
This video is one of many from my "Advanced Academic Driving" book. Consider having a look:
