wwong tai sin temple and CUHK's energy saving project

the most famous temple in hong kong...wong tai sin temple...we went on the 17th of the lunar month and it was still pretty crowded. hmm...we didn't find anything extraordinary about the temple...the architecture was normal and it looks like any normal temple. i guess what's special about the temple is that many people says the deity here is very 'ling'... i drew a lot here and got an uncle to help me 'jie qian'...it was amazing, there were 2 stories full of small shops, each shop have an auntie or uncle to help you jie qian, read your palm, tell your fortune and all these stuff...it got us so confused too...

today's environmental science lesson was pretty interesting...halfway through the lesson, the lecturer took us out to lady shaw building and united college to see the solar panels and solar powered lights and hot water heaters.

this lamp is a very clever invention...it's solar powered and it lights us when there is no light shining on the solar cells at the top.

now, there's no light,
now, there is!! hahaha...and this fountain is powered by a solar panel at the back (refer to the photo below)...
and these are the hot water heaters...there are 11 sets altogether and they cost a total of 200000HKD, which i think is quite reasonable. there is little maintainence required and it does not cause any pollution...
a zoomed up photo of one of the solar powered heaters...each heater can hold up to 160L of water and the water can be heated up to 90 degrees...amazing isn't it? and the panel is so cleverly designed, with all the vacuums, metals, reflectors, angles etc...
my environmental science class...
