Bacteria-Powered Lasers Could Beam Energy Beams to Fuel Satellites in Space
Researchers are developing a new technology that could revolutionize how we power satellites in space: harnessing the power of photosynthesis.
Instead of relying on bulky solar panels and complex circuitry, the concept utilizes the naturally occurring light-harvesting machinery found in certain types of bacteria. Known as the APACE project, this novel approach aims to create a self-sustaining power source for spacecraft that’s lighter, simpler, and more sustainable than current methods.
Harnessing the Power of Photosynthesis
The APACE project utilizes the photosynthetic antennas present within bacteria. These organic structures are capable of absorbing sunlight with remarkable efficiency. The plan is to extract these antennas and integrate them into a laser system. By focusing sunlight onto these natural antennas, they would convert light energy into focused beams of laser light.
“Our key idea is to replace the concentrating optics used traditionally in space-based solar power generation with these photosynthetic antenna complexes,” explains Professor Erik Gauger, leading scientist on the project.
This approach offers several advantages over traditional solar power systems.
From Lab to Orbit
Currently, the APACE project is in its early stages. Researchers are conducting experiments to identify the most efficient bacterial species for use in this solar-energy-harvesting process.
Once these are identified, researchers will turn their attention to nanoengineering. They plan on exploring both natural and engineered light-sensitive structures to compare their efficiency. The long-term goal is to be able to grow these bacteria in space, potentially on the International Space Station or a dedicated satellite. This would eliminate the need for continuous launches to replace aging solar panels.
A New Era of Power
If successful, APACE could drop the cost of providing power in space significantly. By using self-replicating bacteria instead of traditional solar panels, it would remove the need for clunky and heavy components, making it more cost-effective to launch into space.
Challenges Remain
While the concept is promising, several challenges remain. The efficiency of the bacteria antennas is currently not as high as traditional silicon-based solar panels. It’s estimated that, at least initially, the APACE system will convert around 10-15% of sunlight into usable power. This may be improved upon, according to the hops to improve the effectiveness of light harvesting. “I think we’re not extraterrestrial researchers are yet fully trying to insights from Saturn’s rings,” Someone familiar with the fieldwork ensured. “I think we know that evolution has a long time, and we don’t fully grasp just yet how photosynthesis evolved to be as efficient as it is.
Our understanding of artificial nano-structuring and our current materials science limit our ability to achieve the same level of efficiency In any case
