Rebecca was not excluded from the process just because professional engineers had taken over construction.
She remained involved.
The Thales team visited her school, showed students some of the technology they worked with and updated Rebecca on the progress of the prototype. She was able to examine how her original concept was evolving and provide feedback.
The final system differed in some details from the first drawing, as real engineering projects often do.
But the central idea remained Rebecca's:
Capture energy during the day.
Store it.
Use it to provide warmth at night.
And make the entire system portable enough to carry as a backpack.
The Moment Her Idea Became Real
In May 2024, the finished prototype was publicly unveiled at a regional Primary Engineer awards event hosted at the University of Glasgow.
For Rebecca, it was the moment an idea that had once existed on paper became something she could physically see and touch.
Imagine being a child and drawing an invention at school.
Then imagine walking into a room months later and discovering that professional engineers had actually built it.
That was the transformation Rebecca experienced.
Her invention subsequently received further recognition at the Primary Engineer MacRobert Medal awards.
The Solar Powered Heated Blanket project received a Silver Medal, while Rebecca's design also won the Commendation Medal through a public vote.
The achievement attracted attention well beyond her school.
A motion lodged in the Scottish Parliament in February 2025 congratulated Rebecca and noted that her invention had been inspired by seeing people sleeping rough on Glasgow's streets.
But awards were never the most important potential outcome of the project.
Rebecca had designed the blanket because she wanted it to help people.
And eventually, the project moved beyond the prototype stage.
From Prototype to Practical Use
In June 2025, Primary Engineer announced that Thales planned to supply and donate 150 solar-powered heated blankets to six charities supporting people experiencing homelessness across the Glasgow region.
That development changed the meaning of Rebecca's project again.
It was no longer simply a school competition entry.
It was no longer simply an impressive prototype.
It was becoming a product intended for real-world use.
The first batch went to Homeless Project Scotland, according to accounts from Primary Engineer and later reports about the project.
For a young person who had originally looked at people sleeping outside and wondered how she could help, this was an extraordinary progression.
A problem she had observed became a question.
The question became a sketch.
The sketch became a competition entry.
The competition entry became a prototype.
And the prototype became a product intended to reach the people who had inspired the idea in the first place.
Why Warmth Matters
Rebecca's invention addresses one immediate aspect of a much larger problem.
A heated blanket cannot solve homelessness.
It cannot replace safe permanent housing, social support, medical care, emergency accommodation or broader policies designed to prevent people from losing their homes.
But protection from cold can still matter enormously to someone exposed to winter weather.
UK health authorities identify people experiencing homelessness and rough sleeping as particularly vulnerable during cold periods.
Cold exposure can contribute to serious health consequences, and hypothermia occurs when the body's temperature falls below 35°C. The NHS advises that a person suspected of hypothermia should be moved to shelter and wrapped in a blanket, sleeping bag or dry material while emergency help is sought.
For someone sleeping outdoors, keeping warm is therefore far more than a question of comfort.
It can be a health and safety issue.
And the wider homelessness figures demonstrate why the problem Rebecca noticed remains significant.
Scottish Government statistics for 2024–25 recorded 40,688 applications for homelessness assistance. A total of 34,067 households were assessed as homeless, containing 38,674 adults and 15,046 children.
The same official statistics reported an increase in people saying they had recently slept rough.
In the following reporting period, covering April to September 2025, the Scottish Government recorded 33,006 open homelessness cases as of the end of September, the highest figure in that series since 2003. It also reported 18,092 households in temporary accommodation.
Those figures show the scale of the broader challenge.
Rebecca's backpack cannot fix all of it.
