(Trinity College Dublin) Engineers from Trinity College Dublin are leading a four-year, 500,000 European Space Agency project to fine-tune ‘Cold Spray,’ — a revolutionary, environmentally friendly technology that deposits materials onto engineering components. The fruits of their labors will be seen on spacecraft in outer space as well as on a variety of household applications and on the transport vehicles we use every day.


Looks like cool technology. No heat is needed.
