Sounds interesting. But i guess is will be a challenge fot system design? How can we decide in which way to distribute the energy across system components?

Yes...Wow is the word. This sounds like good news.

5KW/kg of this capacitor when compared to 3KW/kg of battery is attractive. A question What is the size of 5Kgs capacitors when compared to 3 kgs battery? I feel will be atleast occupy 5 times the space of the battery. One more question What is the leakage resistance of these caps?Can it retain the charge till the customer uses it?

This sounds promising for ultra low-power applications in which energy harvesting and ultracaps can provide all the power needed. The flashlight example is a good one -- probably only a couple hundred mA-hrs of energy storage needed. But I don't see how these hybrid ultracaps can store enough energy to be practical in HEV's.

Safety: Distributed energy may not be a good match for automotive applications. Presently if a vehicle is involved in a collision the fire department cuts a battery cable to remove all electrical energy as a source of ignition.

This is a welcome development in the sense that the safety system of a vehicle for instance will not rely on the conventional battery.In event of an accident any survival part of the vehicle could function and aid for resuce of the occupants. Aja Nwaeke

The ultra capacitors is not anew concept but the way Loxus is talking about distributed ultra capacitors with energy harvesting is something innovative. Apart from energy harvesting , these ultra capacitors can also be charged in seconds at a charging station as against hours required for charging batteries. The combination of energy harvesting and chargeable ultra capacitors can make a good combination for Electric vehicles. As pointed out by Selinz , the title should be better ultra capacitors and not better battery.

What is the highest voltage rating of these ultra caps? Not even 6 volts? Three volts?

It seems silly to title the article "better battery" and then talk about capacitors. The article then describes the attributes of a having a capacitor engergy storage device as if it were different than a hybrid (with battery storage).

Wow. this is probably one of the first technologies that I have read about that could really be a game changer.. simple (relatively to some emerging types) and mass producable( usable in cars and laptops and flashlights)

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
