Fast trains in a solar-powered Europe

A few interesting engineering-related developments in the news today:

There is a proposal to provide most or all of Europe's energy needs with solar collector farms in the Sahara, slashing the continent's carbon emissions dramatically.
England's parliament has approved the Crossrail rail scheme; from 2017—in nine short years—London will have a fast east-west underground rail link, sort of like Paris's RER, going from Paddington, under Tottenham Court Road and Farringdon, and hitting Stratford and Canary Wharf.
