| When
Siang was an architectural student in university, he spent his summer
holidays trekking in Nepal, where he was offered to design a hotel
in Pokhara. As the construction progressed, Siang encountered major
obstacles. One was the lack of electricity for heating water. Solar
energy was in abundance up in the Himalayans. He was compelled to
come up with a more efficient solar-powered water heater. He worked
on many ideas and design until he perfected one that uses a multi-valve
system. It proved to be quite revolutionary, and Time Magazine honoured
him as one of the Heroes for the Planet in 1999. |
