I like this article. Energy density for portable applications is a real limiting factor for many otherwise worthwhile or essential products. This is a good leadin to a look at advances in battery technology and capacitor technology. Very useful!

WRONG! In this article there is the wrong assertion: "...the supercapacitor will draw short circuit current from the solar cell when it is at 0V. As it charges, the current reduces according to the solar cell V-I characteristic, but at all times, the supercapacitor is drawing the maximum current it can, so it is charging at the fastest possible rate..." This is wrong because the power delivered from source is very small when voltage is near to 0V (see magenta line on Fig.4). If source work at MPPT then the power delivered to supercap is max and charge time is minimum. Santo Ilardo

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
