After devouring nearly as much energy as all of Iceland’s households combined, bitcoin miners may be about to return something to the community that’s housed them.

Iceland is looking past the faddishness of cryptocurrencies and toward other projects that need the same kind of infrastructure bitcoin miners rely on. These include areas like deep learning applications for self-driving cars or automatic translators.

Bitcoin “probably won’t be here far into the future” said Johann Snorri Sigurbergsson, business development manager at the HS Orka power plant in Iceland, which provides electricity to the data centers that miners use. But the centers themselves will become new technology incubators, and “that’s the bet we’re making,” he said.

Mining for bitcoin requires lots of energy, both to do the actual mining but also to cool the enormous computers used to crack the codes that release the limited supply of bitcoin. Iceland estimates the industry will consume more than 100 megawatts by the end of the year.

The island became a magnet for the practice once miners figured out that the place is very cold and that electricity there -- geothermal and hydropower -- costs a lot less than in most other places. Iceland’s cheap energy has already drawn other power intensive industries, such as aluminum smelting.

PAINFUL MEMORIES 

Iceland is more sensitive than most to the risk of supporting an industry that may be headed for bust. It still has painful memories of the 2008 banking meltdown, which drove the island into the arms of the International Monetary Fund and resulted in capital controls that have only just been lifted.

The future of bitcoin, and other cryptocurrencies, is far from clear. After soaring close to US$19,000 late last year, it crashed to less than US$6,000 last week. Many other forms of cryptocurrency -- Dead Coins lists about 800 now effectively worth nothing -- have collapsed entirely.

But Iceland also needs to diversify its economy to rely less on fishing, tourism and aluminum smelting. And that’s where the data centers created to enable bitcoin mining could play a key role.

BUILDING KNOWLEDGE 

Gisli Kr. Katrinarson, chief commercial officer at Iceland’s biggest data center operator, Advania, says it has “developed immense knowledge about the most efficient ways to operate and maintain these blockchain systems" and is now using this knowledge and experience "to increase the quality of service for our customers.”

For Iceland, that means a much clearer path to reaping the benefits of the digital age. Katrinarson says Advania is already working with Stanford University and HP Enterprise on simulating how a virtual human heart might respond to experimental medication.

“The fourth revolution is starting,” said Asgeir Margeirsson, chief executive officer of the HS Orka power plant. “It would be terrible for us in Iceland not to follow that development. If we were not to take part in the next development into the future, we would slide back.”

Kristinn R. Thorisson, director of the Icelandic Institute for Intelligent Machines, says the data centers currently being used by bitcoin miners are “central to the industrial revolution that is still under way.” Artificial intelligence today still requires “way more data than computing power.”

“There is less supply than demand right now,” said Thorisson, who predicts "a significant reliance on data centers" for "at least the next 50 years."
