Một công nghệ sạch mới để biến ánh sáng mặt trời thành nhiên liệu lỏng có thể thu nhỏ nhu cầu cho các đồn điền lớn trồng cây nhiên liệu sinh học, các nhà nghiên cứu trường Đại học Harvard cho biết hôm thứ Năm.
Điều đó có thể giúp bảo vệ nguồn cung cấp thực phẩm và quyền sử dụng đất của người dân, họ đề nghị.
Được mệnh danh là "bionic lá 2.0", công nghệ sử dụng năng lượng mặt trời để tách các phân tử nước thành oxy và hydro, các nhà khoa học cho biết trong một nghiên cứu công bố trên tạp chí Science.
Khi tách ra, hydro được chuyển vào một căn phòng, nơi nó được tiêu thụ bởi các vi khuẩn, và với sự giúp đỡ từ một đặc biệt kim loại xúc tác và carbon dioxide, quá trình tạo ra nhiên liệu lỏng.
Phương pháp này là một phiên bản nhân tạo của quá trình quang hợp thực vật sử dụng để tạo ra năng lượng từ ánh sáng mặt trời, nước và carbon dioxide, các nhà khoa học cho biết.
Nếu nó trở nên hiệu quả kinh tế, công nghệ này có thể thay thế các giếng dầu hoặc các đồn điền nơi cây lương thực được trồng để lấy nhiên liệu, tác giả chính của nghiên cứu cho biết.
