BLUE-PLUME - Blue Laser Planetary and Lunar Management of Electrical Power

NASA#39;s Moon to Mars Objectives underscore the need for a novel lunar amp; Martian power grid, essential for continuous human, robotic operations, and scalable to industrial power levels. Traditional electrical grid designs usenbsp;heavy copper or aluminum wires and are neither economically nor logistically practical. The ability to power moving rovers or short-term stations enhances exploration scenarios, crucial for diverse tasks across missions. The technology also enables a centralized approach, eliminating the need for complex cable networks associated with traditional grids.nbsp; The Phase I project showcased the feasibility of NUBURU#39;s blue laser power beaming solution. The technology was advanced to TRL level 4 with a laboratory prototype. Phase II builds on this success, focusing on high-power receiver development and extending the range of the blue laser transmitter. This approach is a breakthrough in laser power beaming, offering an efficient, adaptable, and cost-effective solution. Phase II will advance the technology in three key areas: 1) Validation of thin-film solar cell technology at high power densities, 2) Demonstration of multi-kilometer long-range power beaming, and 3) Scaling up the blue single-mode laser source. NUBURU will demonstrate a high-power receiver at 200-500W at 1-3 km range and a long-range laser source at 5-50W capable of 10+ km range, collectively elevating the TRL level to 5. Blue laser power beaming is a transformative innovation for lunar and planetary power distribution, offering distinct advantages over competitors reliant on inferior infrared (IR) or green laser technologies. Blue lasers present low Size, Weight, and Power (SWaP) design, clear visibility aiding navigation, and efficient direct diode technology. The blue wavelength allows us of advanced direct bandgap, thin filmnbsp;solar cells, ensuring higher conversion efficiency compared to IR. The visible blue laser additionally provides navigational benefits to remote sites.
