1. RAS technology has been under intensive R&D for over 30 years.
  2. Many pilot systems with varying degree of efficiencies and performances have been developed.
  3. During early years of RAS development, lack of understanding of this new technology has led to many unsubstantiated and wild claims on their capacity and performance outputs.
  4. This has resulted in many early failures in transferring this technology to some countries and to investors resulting in bad publicity for the RAS technology.
  5. However, the situation is changing rapidly and in recent years, many successful and economically viable RAS have been set up in Australia, Europe and America.
  6. Commercial RAS have been proven to be successful in countries like China (70%), Australia, USA, Canada and Europe.
