I would like to see more development in the ultra/super capacitor arena. I used some in a project to replace a 9V battery, and they worked great. I will admit that the Joule density wasn't quite the same, but the recharge time was the balancing benefit. I would like to see extremely small 5V - 100F caps. The potential in such a cap would make it quite popular. I would have to agree, caps are the way to go for mobile devices. However, more energy elegance needs to be applied to these devices. Right now it is pretty brute force.. need more battery life?... install a bigger battery.
As others have posted, this does seem to be brochure quality. While a certain percentage of technical articles are written by those with a vested interest in promoting the technology (such as this one), most tend to be white-paper quality with a much higher percentage of background information...and then put the marketing spin on top of it to show how that particular product leads the industry. This one seems to have missed the first part.
While I appreciated learning about the uses and applications for ultracapacitors, some diagrams, description of the manufacturing process, or any other hard data would have rounded out the article for me.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
