Rebecca Young, a 12-year-old student from Scotland, has developed a solar-powered backpack equipped with an integrated electric blanket to protect unhoused individuals from freezing temperatures. the invention, which won the 2024 Primary Engineer annual competition, is now being manufactured through a partnership with veterans' charities and engineering firms.
The Primary Engineer competition and the 2024 silver medal
Rebecca Young's project began as an entry for the Primary Engineer annual competition, where her design for a portable heating solution secured the top spot in 2024. as reported by the source , Young's work was further recognized in May 2024 at the University of Glasgow during the Scotland West regional award ceremony, where she was awarded a silver medal for her design.
The visibility of the project has extended far beyond the classroom. Time Magazine featured Young in its Best Girls of the Year 2025 list, specifically designating her as an "Innovator." This recognition, coupled with the creation of a custom Lego minifigure in her likeness, underscores a growing cultural trend of elevating youth-led STEM solutions that address immediate humanitarian crises.
How Thales UK and RBVE scaled 120 prototypes into production
Moving a concept from a student project to a functional product required industrial expertise. According to the source, Thales UK, a partner of Primary Engineer, stepped in to prototype the first 120 blankets. thales UK worked directly with Rebecca Young to iterate on the design, introducing critical safety features and multiple heat settings to ensure the blankets were safe for prolonged use by people sleeping outdoors.
The production process has since expanded through the Royal British Veterans Enterprise (RBVE). This national charity employs veterans and individuals with disabilities to assemble the solar-powered units, effectively turning the manufacturing process into a job-creation engine for marginalized workers. To ensure a steady flow of equipment to those in need,the RBVE has implemented a matching pledge, donating one blanket to charity for every unit sold.
Addressing the brutality of Scottish winters for the unhoused
The invention targets a specific environmental hazard: the brutally cold Scottish winters. For the unhoused population in cities like Glasgow, where the first batch of blankets was distributed to a local shelter, the ability to maintain body heat is a matter of survival. By combining foldable solar panels with a battery pack for energy storage, Rebecca Young's design allows users to harvest energy during the day to survive the night.
This approach reflects a broader shift toward "appropriate technology"—the design of tools that are low-maintenance and energy-independent for users who lack access to a power grid. By integrating the blanket into a backpack , the design acknowledges the mobility requirements of the unhoused, ensuring that life-saving warmth does not become a logistical burden to carry .
The long-term durability of foldable solar panels in Glasgow
Despite the successful rollout, several technical questions remain regarding the device's efficacy in the field. Specifically, it is unclear how the foldable solar panels perform during the peak of winter in Scotland, where heavy cloud cover and short daylight hours significantly limit solar gain. The source does not detail the battery capacity or how many hours of heat the blankets provide on a single charge.
Additionally, while the partnership between Thales UK and the RBVE has streamlined production, there is little information on the long-term maintenance of these units. Because the blankets are intended for use in harsh street conditions, the durability of the electronic components and the process for replacing damaged battery packs remain unverified points in the current reporting.
