If you thought the Fukushima disaster derailed nuclear power worldwide, look again.

Evacuations and the havoc caused by meltdowns at four reactor cores at the Fukushima power plant earlier this year prompted Japan to shift away from nuclear power and recatalyzed a nuclear phase-out in Germany. But many countries remain enthusiastic about nuclear power, and interest in newer technologies has increased because they are safer, according to a panel of industry professionals here at the MIT Energy Finance Forum on Friday.

“Our investors have a very long time horizon and the reason they supported it is the long-term societal implications and the potentially significant returns from that (so) we haven’t seen any wavering of support,” said Tyler Ellis, a project manager at TerraPower. “Our development partners are trying to accelerate the time scale (of building plants) due to the energy security and safety.”

India's New Nuclear Build


Protest at Jaitapur over planned construction of two new nuclear reactors.

A series of protests that began in October have delayed the hot start of two Russian 1000- MW VVER reactors in the Tamil Nadu state on India’s southernmost coastline. Additional protests, some of them violent, have set back the start of construction of two French 1650-MW EPR reactors in the Maharashtra state on India’s west coast some 400 km (250 miles) south of Mumbai.

Imagine if nuclear power was safe, terror-proof, and fueled by a plentiful, ubiquitous element. Sound like a pipe dream? Maybe it is. Maybe not.

A couple nights ago, I dropped by the Vice magazine offices in Brooklyn to check out a new documentary on thorium put together by Motherboard.tv. (Full disclosure: the video was produced by Alex Pasternack, a former contributor here at TH.) The film, The Thorium Dream, examines the history of an alternative kind of nuclear power, one tested decades ago but never embraced.

Airborne Metro A Giant Nuclear-Powered Airport That Flies 3,000 Passengers Across the Sky

When it comes to aircraft, bigger is better. As size increases, so does efficiency, which is the thinking behind the monstrous Airbus A-380. But to be really efficient, you’d need to go bigger. Way bigger. We’re talking an aircraft so large that other aircraft could land on it, in-flight.

The “Airborne Metro” concept is just that: it’s like an express train in the sky. As part of a general metro or train system, though, you don’t get to take the express line directly from start to finish. Instead, you take a smaller bus or train to get to the express train, and then probably another smaller bus or train to get to your final destination once you get off the express. In the case of the Airborne Metro, you’d catch a regular aircraft at a regional airport, zip up to a giant flying airport, and then ride that for a couple thousand miles before taking another regular aircraft back down.
