That's smart.
Very very smart!
Wow! This is so awesome! Very smart!
You know, they have a dance floor in Japan where it is powered by human/kinetic energy (dancing). My science teacher told us about it.
That's pretty smart. Using human-kinetic energy/heat is a good idea if it gives sufficient energy.
Wow! This is amazing! If this was installed in a home, it would really help the homeowner!!!
