ENERGY AT HOME Conservation of Energy: 1.Reduce 2.Reuse
3.Recycle Alternative sources (Green): 1.Solar Energy 2.Rainfall
3.Sound/Music 4.Movement Exercising (Gym equipment): Generates
electricity to power the house Hamster wheel (Hamster Cage)
Different electrical appliances: e.g. Cellphone | Lightbulb TV |
Washing Machine | Aircon/fan Using energy from one activity to
power another activity (Battery/Storage Cells)
Target Group -General public -Active people (Exercise

` Focus We have seen that temperatures and rainfall are on the
rise. Coupled with the imminent global issues of global warming and
climate change, it is important to invest in alternative cooling
methods without causing more damage to our only home. This is
especially relevant in Singapore where we experience summer all
year round and people choose to counter this weather via
air-conditioning. However, it is important that we must not neglect
the experience of the user while tackling this issue. We believe
that the two are not mutually exclusive and we can achieve both at
the same time.

` Precedence Harvesting Energy from Rainfall -Commonly used in
large scale dam projects to generate electricity -US hydroelectric
production accounts for 7.5% of total electrical production Kinetic

5.5 hours of electrical- generating sun each day, 300+ days per
year Taken from http://www.ext.colostate.edu/pubs/consumer/10624.h

` Precedence Methods to maintain the room at a comfortable
temperature Houses gain/lose heat through: 1.Air infiltration
2.Heat conduction 3.Solar radiation According to one government
study, winter heating bills may be reduced by as much as 15 % while
summer cooling energy needs may be cut by as much as 50%. Taken
