Potential Competition

Desalination is seen by some to be 'competition' and in this sense will set a price ceiling when all other factors such as security and environmental issues have been taken into account. 

Although transportation by new steel-hulled tankers ( i.e. unused and straight from the builders) is likely to cost as much as four times as much as by VLFBs and tugs it may appear to laymen as more secure until large bags have proved their reliability.  In this sense the environmental economics of new tanker transportation will set the threshold parameters which will have to be improved upon in the advocacy of large bag transportation.  

The only other bag system currently known to have been under development is Spragg of California (see http://www.waterbag.com)
