: "Companies with just a toehold in the field of nanotechnology thus eagerly embrace their nano side.

: Please, can anyone explain what these 14 orders of magnitude are about? Thanks.

'nano' is 10 to the power of minus nine = 10n-9, whereas global is related to the size of the earth - a scale of some thousand Kilometers. a 'kilo' is a multiplier of 10n4 so between 10n-9 and 10n4 are 14 orders of magnitude.
