- Nanotech battery charges smartphone in 30 seconds
- A quote from another article on the battery ( http://www.eetimes.com/document.asp?doc_id=1321873& ) suggests lithium-like discharge performance: "The battery's electrodes are based on multifunctional "nanodots" derived from bio-organic material, enabling both very fast supercapacitor-like charging on one side and slow discharge -- like a lithium electrode -- on the other."

- Here is StraightWireAudioBill's comment that he was unable to post due to a commenting system bug: Hi Katgod, A few years ago Dr Sean Olive was a member of a panel I chaired for a session at AES. Sean presented the data referenced below in his formal paper on the subject of perceptual acuity of the "mp3 generation", which one can obtain from AES; Some New Evidence that Teenagers and College Students May Prefer Accurate Sound Reproduction - Sean Olive, Harman International Industries Inc. - Northridge, CA, USA A group of 18 high school and 40 college students with different expertise in sound evaluation participated in two separate controlled listening tests that measured their preference choices between music reproduced in (1) MP3 (128 kbp/s) and lossless CD-quality file formats, and (2) music reproduced through four different consumer loudspeakers. As a group, the students preferred the CD-quality reproduction in 70% of the trials and preferred music reproduced through the most accurate, neutral loudspeaker. Critical listening experience was a significant factor in the listeners' performance and preferences. Together, these tests provide some new evidence that both teenagers and college students can discern and appreciate a better quality of reproduced sound when given the opportunity to directly compare it against lower quality options.

- There is currently a bug in our commenting system where the inclusion of higher-ascii characters (such as special characters or smart quotes or apostrophes like those commonly used in Word) in a comment can cause it to disappear. The bug is being worked on. In the meantime, removing/replacing such characters or using a basic text editor like Notepad to compose comments should avoid the issue.
