Algae Biofuels Project Abandoned by Exxon Mobil due to Economic Challenges
The use of algae for biofuels has long been considered a promising solution for creating cleaner and renewable energy sources. However, efforts to commercialize the process have faced significant challenges, with Exxon Mobil recently abandoning their algae biofuels project due to economic factors.
Algae contain high levels of lipids and are more versatile than corn, but crude oil remains significantly cheaper. This economic disparity has made it difficult for companies to make the economics of algae biofuels competitive with that of crude oil.
Scientists Study Photosynthesis at Molecular Level to Discover New Energy Extraction Methods
An international team of scientists led by the University of Cambridge recently made a breakthrough in the study of photosynthesis at a molecular level. Using superfast spectroscopic techniques and lasers, they studied how ring-shaped molecules called quinones can ‘steal’ electrons from photosynthetic cyanobacteria in real-time.
This discovery is a potential gamechanger for future applications such as biofuels and developing more efficient crops for future biofuels. By mimicking photosynthetic processes, scientists can generate clean fuels from just sunlight and water to address the climate crisis.
Former Wick High School Pupil Extracts Electrons from Plant Cells to Create Renewable Energy
Tomi Baikie, a former Wick High School pupil, recently attained his PhD from the University of Cambridge. Together with his supervisor Dr Laura Wey, they came up with the idea of using lasers to look into plant cells and extract energy.
Using ultrafast spectroscopic techniques, they found chemicals that can extract electrons from the molecular structures responsible for photosynthesis. Tomi managed to extract electrons from the cell, allowing cells/plants to work as solar cells. The ability to regulate photosynthesis could mean that crops could be made more able to tolerate intense sunlight.
The team was surprised by the success of their experiment and said they now have a “new tool to understand cells”. They believe the quantum electronics of the plant world could be used to inspire new, more efficient devices such as displays and solar cells.
Ultrafast Spectroscopy Provides New Understanding of Photosynthesis
Understanding photosynthesis is a difficult task for humans due to the involvement of electrons and atomic-level physics. However, researchers from Cambridge University recently used laser pulses to take images of live plant cells to study their reaction centers and flow of energy.
Their technique allowed them to observe the movement of electrons and identify new electron transfer pathways, leading to a better understanding of photosynthesis. The team is excited about the potential of ultrafast spectroscopy to provide rich information on living systems dynamics.
This new understanding of photosynthesis could potentially be used to reengineer plants to tolerate more sun or create formulas for cleaner, light-based fuel. It provides hope for developing sustainable energy sources without harmfully impacting our environment.
In conclusion, scientists have made significant strides in extracting energy from photosynthesis, with promising implications for generating clean fuels and developing renewable energy sources. The use of innovative technologies like ultrafast spectroscopy and lasers has enabled researchers to study photosynthesis at a molecular level, leading to new discoveries about electron transfer pathways and cell functions. These findings offer hope in solving some of today’s most pressing challenges regarding climate change and energy security.
