Spain extended its free train travel program through December 2023, allowing summer visitors to ride commuter and medium-distance Renfe trains for free by purchasing multi-journey tickets (minimum 10 return trips) with a small deposit of €10–€20 that must be earned back through 16 completed journeys. High-speed routes like Madrid-Barcelona are excluded from the scheme, which has proven popular among locals and may be made permanent due to its environmental benefits and €764 million cost funded by a windfall tax on banks and energy companies.

Electric Roads — Marginal Revolution

Researchers are developing buried charging pads in roads that would wirelessly transfer electricity to vehicles as they drive, potentially reducing EV battery sizes by 80 percent and eliminating the need for frequent charging stops. This approach shifts the energy storage burden from the vehicle to the grid infrastructure, allowing EVs to operate with much smaller, cheaper batteries while maintaining long-distance driving capability. The technology, pioneered in New Zealand, could fundamentally change EV design and economics by making vehicles lighter and more affordable.
