[edit] Efficiency

Added some details on efficiency. Some air engines are promoted as environmentally friendly and highly efficient in the media, but it is important to look at the system efficiency. In some cases, the air engines may prove to have a favourable system efficiency against competing technologies, but is never going to be better than 35 to 40%, and probably less than 25% if fossil fuels are used to derive the energy for compression.

[edit] Commented You Tube link.

1 link commented out - Status unclear - No clear indication that uploader is associated with the footage concerned, however it might be worth someone checking what the status of the clip is as it's not obvious copyvio. Sfan00 IMG (talk) 00:22, 19 November 2007 (UTC)

[edit] Might be nice

Might be nice, if you are going to criticize the efficiency in this obviously biased article, to actually have some numbers to show that it is less efficient than other technologies. —Preceding unsigned comment added by 74.226.76.132 (talk) 07:43, 13 February 2008 (UTC)
