Not sure if this is sci fi or we will really see it one day.

Pros:

• Perfect for tropical countries where there are lots and lots of trees and plants
• Developing countries when electricity is scarce
• Free energy is always good. More needs to be done to research this and promote its use

Cons:

• Waiting to see if this product is to be release
• Price. If price is too high, it will not be favourable
