First Solar Tunnel To Help Power High-Speed Trains Opens In Europe

This 3km tunnel running on solar power just switched on today. It's part of the Paris to Amsterdam line and the first in Europe, promising to save a ton of energy that would otherwise be wasted during the trip.

Now Paris and Amsterdam obviously aren't two miles apart. But this thing features a 16,000 solar panel array that could power 50 per cent of the entire Antwerp station, where the first train to pass through it departed from. Imagine if more of these popped up on other train lines. [Treehugger]
