Ground-level power supply, also known as surface current collection and Alimentation par le Sol (APS), is a modern method of third-rail electrical pick-up for street trams. It was invented for the Bordeaux tramway, which was constructed from 2000 and opened in 2003. Until 2011, this was the only place it was used, with proposals to install it elsewhere. Reims has adopted this technology for its new tramway, which was opened in 2011, as has Angers.

“Either you think—or else others have to think for you and take power from you, pervert and discipline your natural tastes, civilize and sterilize you.”
—F. Scott Fitzgerald (1896–1940)
“Dear to us are those who love us ... but dearer are those who reject us as unworthy, for they add another life; they build a heaven before us whereof we had not dreamed, and thereby supply to us new powers out of the recesses of the spirit, and urge us to new and unattempted performances.”
—Ralph Waldo Emerson (1803–1882)
