I really think science can uncover other energy sources as they did this artificial’ leaf with basic research as mentioned in this article about the possibility of more efficient photosynthesis. Read it an see if you agree.
“Improving natural photosynthesis to make new fuels and boost crop production is the focus of new research presented at the American Association for the Advancement of Science (AAAS) Annual Meeting today.
It could see us one step closer to bottling the sun’s energy or turbocharging plants to produce bumper crops. Photosynthesis allows biological systems to take energy from the sun and use it to produce food and fuel. It is one of the most important biological processes on earth but it’s not as efficient as it could be. Natural trade-offs results in less than 1% efficiency in many important crops and so there is significant scope for improvement.
Scientists from the UK and US are working to engineer or enhance photosynthesis to benefit food and fuel production. Professor Douglas Kell, Chief Executive of BBRSC, explains why funding this research is vital: “We are facing global challenges in food and energy security that must be addressed. Improving photosynthesis within plants, or externally using synthetic biology, would bring huge benefits.”
