@Larry: Wow, Colin, I've read a lot of your articles over the years and I can't think of any that I would describe as 'fluffy'.

How about cuddly? LOL

I agree with you -- a lot of people just want to be provided with a high-level view, not burried under mounds of techno-babble -- the purpose of thsi type of column is to make folks aware of what's going on -- so long as it then links to the main report with all the numbers, I think it's perfect -- that way the folks who want the numbers know where to go to gorge themselves :-)

Wow, Colin, I've read a lot of your articles over the years and I can't think of any that I would describe as 'fluffy'. I sympathize with the desire to get hard information, but it also has to be accessible to people that do not specialize in that field. Following an extra pointer to get to the research paper is a small step to take for those who are.

Keep up the good work!

In the story I only included the "summary" number--that they had achieved 100 F/g, but if you click on the report link you can get the rest of the numbers the researchers report. Here's a few examples from the report:

"single-walled carbon nanotube (SWCNT) thin film and achieved specific capacitance of 33 F/g and a high specific power of 250 kW/kg with an organic electrolyte...improved the graphene synthesis technique and reported a simple activation with KOH of microwave exfoliated graphite oxides and thermally exfoliated graphite oxides to achieve specific capacitance around 200 F/g in organic electrolyte...After laser reduction, the...ultracapacitor offered a specific capacitance of 265 F/g in an organic electrolyte with a wider operating voltage window of 3 V...sheet resistances of the SWCNT and composite thin films were 440.2 and 90.5  Ω /sq at room temperature, respectively...the capacitance of SWCNT and composite ultracapacitors can be estimated as 110 and 40 mF. The thin film of carbon nanostructures has the weight of 1.1 mg and surface area of 1 cm 2. Therefore, the specific capacitances of SWCNT and composites ultracapacitors were calculated as 100 and 36 F/g, respectively...According to Galvanostatic charging/discharging measurements, the specific capacitance of ultracapacitors was approximately calculated as 95 F/g for composites and 28 F/g for SWCNT...

More numbers in the report

This is the same fluffy post as everywhere else. We engineers expect numbers.
