Dear MEL School’s Topic Readers,
Potato power: the
spuds that could light the world.
What is the most
practical and economical way to light a LED bulb or charge your mobile phone in
a place where no electricity is available? One of the answers is the potato.
Scientists have
been studying the most effective way to generate organic power from various
kinds of potatoes in various ways of processing. They've found that a single
potato can power enough LED lamps for a room for 40 days. That sounds more
economical than using dry batteries, doesn't it?
However, there are
other aspects to look at this issue. Which should be more prioritized, food or
energy? In some places of the world, potatoes are the major source of diet. So,
feed people first then light bulbs afterwards. Another aspect to look at is emotion.
Do you want to light your house with leftover potatoes or by solar panels?
Enjoy reading and
learning about this new way of using this ordinary food for energy.
