Hi, everyone! I want to tell you about a really cool type of energy.
You guys know about clean energy from the sun and wind, right? But do you know about energy from algae?
你有聽說過藻類也可以發電嗎？
Algae are those green things you see in water sometimes. You can find them in all kinds of water, like lakes and the ocean.
你常常可以在湖面上或是海面上看到綠色的藻類。
It is kind of yucky if you swim in algae, it's so slimy! But, algae can also be used to make clean energy.
藻類黏糊糊的，在裡面游泳很噁心。不過它們可以提供乾淨的能源！
Algae are plants. All plants use photosynthesis.
藻類是植物，會行光合作用。
Plants use photosynthesis to make energy, which helps them grow. Now people are using this energy to make electricity. Wow! It's like a battery that keeps making power!
植物經由光合作用產生能量，幫助生長。現在人們可以用這種能量來發電！
The scientists have used this algae battery for more than a year. And it's still making enough energy to power a small computer!
科學家用藻類發電已經一年多了，電力足夠供應一台小電腦。
This is so exciting! Why? Well, algae doesn't cost anything, you can get it almost everywhere!
而且藻類到處都有！
We use a lot of energy every day. This algae battery can help us a lot. It can help make the world a cleaner place!
