The slow-motion political race to build tiny stars on EarthMar 04 2014

Raffi Khatchadourian's long piece on the construction of the International Thermonuclear Experimental Reactor (ITER) is at once fascinating (for science reasons) and depressing (for political/bureaucratic reasons). Fusion reactors hold incredible promise:

But if it is truly possible to bottle up a star, and to do so economically, the technology could solve the world's energy problems for the next thirty million years, and help save the planet from environmental catastrophe. Hydrogen, a primordial element, is the most abundant atom in the universe, a potential fuel that poses little risk of scarcity. Eventually, physicists hope, commercial reactors modelled on iter will be built, too-generating terawatts of power with no carbon, virtually no pollution, and scant radioactive waste. The reactor would run on no more than seawater and lithium. It would never melt down. It would realize a yearning, as old as the story of Prometheus, to bring the light of the heavens to Earth, and bend it to humanity's will. iter, in Latin, means "the way."

But ITER is a collaborative effort between 35 different countries, which means the project is political, slow, and expensive.

For the machine's creators, this process-sparking and controlling a self-sustaining synthetic star-will be the culmination of decades of preparation, billions of dollars' worth of investment, and immeasurable ingenuity, misdirection, recalibration, infighting, heartache, and ridicule. Few engineering feats can compare, in scale, in technical complexity, in ambition or hubris. Even the iter organization, a makeshift scientific United Nations, assembled eight years ago to construct the machine, is unprecedented. Thirty-five countries, representing more than half the world's population, are invested in the project, which is so complex to finance that it requires its own currency: the iter Unit of Account.

No one knows iter's true cost, which may be incalculable, but estimates have been rising steadily, and a conservative figure rests at twenty billion dollars -- a sum that makes iter the most expensive scientific instrument on Earth.

I wonder what the project would look like if, say, Google or Apple were to take the reins instead. In that context, it's only $20 billion to build a tiny Sun on the Earth. Facebook just paid $19 billion for WhatsApp, Apple has a whopping $158.8 billion in cash, and Google & Microsoft both have more than $50 billion in cash. Google in particular, which is making a self-driving car and has been buying up robots by the company-full recently, might want their own tiny star.

But back to reality, the circumstances of ITER's international construction consortium reminded me of the building of The Machine in Carl Sagan's Contact. In the book, the countries of the world work together to make a machine of unknown function from plans beamed to them from an alien intelligence, which results in the development of several new lucrative life-enhancing technologies and generally unites humanity. In Sagan's view, that's the power of science. Hopefully the ITER can work through its difficulties to achieve something similar.
