Homelessness remains one of the UK’s toughest challenges, with thousands forced to sleep rough each year.
Now, a 12-year-old from Glasgow is showing how even the youngest innovators can spark solutions — by inventing a solar-powered backpack that unfolds into a heated blanket
From Idea to Invention
As part of the Primary Engineer’s annual UK STEM competition which drew more than 70,000 entrants, Rebecca unveiled her invention to the world with the aid of a diagram.
Her design stood out: a backpack fitted with solar panels and battery pack, storing energy during the day to power a heated blanket at night.
Engineering firm Thales saw the potential and partnered with Rebecca to turn her concept into reality. Together, they developed prototypes with adjustable heat settings and ensured it was lightweight and practical for those living rough.
By May 2024, they completed their first prototype together. Rebecca’s invention went on to earn her a Silver and a Commendation Medal judged by public vote in the Primary Engineer® MacRobert Medal competition, one of the UK’s most prestigious engineering competitions.
A Real-World Impact
According to Crisis UK, homelessness arises in the UK for many reasons.
Some people face homelessness because they can no longer afford their rent. Others have been pushed out of prison or the army, with no place to live.
Physical or mental health problems, substance abuse, the loss of a job or ending of a relationship can put people under pressure to pay the bills.
Whatever the cause, thousands of people are left on the streets, and the freezing nights are often the harshest reality.
Rebecca’s invention aims to ease that burden. Thales pledged to donate 150 backpacks to charities in Glasgow, with 35 already delivered to Homeless Project Scotland.
Colin McInnes, founder of the charity, praised Rebecca’s compassion and creativity. He told the BBC that she was a “role model for any young person,” adding that blankets would be given out on rough nights when shelters are full.
Recognition Beyond Glasgow
Rebecca’s idea has captured attention far beyond her hometown. In August 2025, she was named one of Time magazine’s inaugural “Girls of the Year.”
LEGO even created a mini-figure in her likeness, which appeared on the digital cover of Time.
More Than Just a School Project
For Rebecca, what began as a school competition entry has become a mission.
Her invention is proof that even the biggest societal issues can be challenged by small acts of empathy, imagination, and innovation.
