Bài khóa

Could your garden power your mobile phone?

Scientists at Cambridge University are investigating how plants can give us sustainable energy.

They do this by collecting electrons released naturally by plants and turning them into electricity. You can even create your own algae solar panel.

But a lot of work needs to be done to make the process more efficient.

Liệu vườn của bạn có thể nạp điện cho điện thoại di động?

Các khoa học gia tại Đại học Tổng hợp Cambridge đang tìm hiểu cây cối có thể cung cấp cho chúng ta năng lượng bền vững như thế nào.

Họ thực hiện việc này bằng cách thu thập điện tử do cây cối phát ra tự nhiên và biến chúng thành điện. Bạn thậm chí có thể tạo ra bảng năng lượng mặt trời từ tảo.

Nhưng còn cần phải làm rất nhiều để cho quá trình này trở nên có hiệu quả hơn.
