According to Phononic, the fans use 50% less energy, making them more environmentally-friendly than air conditioners and bladed fans.
SINGAPORE (Nov 18) : A US start-up backed by Temasek Foundation, the non-profit arm of Singapore’s state-owned investment firm, is set to beat Singapore’s humidity with a new bladeless fan.
Temasek Foundation is investing US$1 million ($1.4 million) in Phononic to help develop the pilot project, called Outdoor Active Cooling in Singapore (OACIS). Eight OACIS fans are currently on trial in Singapore.
