Humans have been making beer for more than a millennium, but the old techniques of the monks are giving way to more modern methods. One brewery on the New South Wales central coast is avoiding charges on its excess solar energy by using it to power a bitcoin mine and using all the heat if gives off to make beer.

00:02Thinking outside the box on energy efficiency.
00:05The key for us was to find a way of producing hot water to be able to make our beer
00:09the
00:09cheapest way we can make it.
00:10For this brewery, the cheapest way involves using excess solar energy to power a Bitcoin
00:16mine, which competes to verify transactions and unlock more of the cryptocurrency.
00:22A Bitcoin miner is just a high powered computer, a processor, and it works at such a high rate
00:28that it runs really hot.
00:30Because you're pumping so much power through these systems, so you might be using on the
00:35order of 20 or 30 times what a regular PC would be doing.
00:39The computers are submerged in a non-conductive liquid to stop them from overheating.
00:44That liquid absorbs the temperature and in turn warms up the water to make the beer.
00:49All our beer is made with that hot water.
00:51Everything we produce in here, all our cleaning, our waste that we need to do with hot water
00:56is done via that process.
00:58From a Bitcoin mine in a shipping container to the final product that's come out of the
01:03taps, this unique process generates enough heat to produce 100,000 litres of beer every
01:09month.
01:10In addition to providing no-cost heating, the Bitcoin mine helps the brewery offset other
01:15operating costs by earning payments for solving complex puzzles.
01:19It's a payment for processing for those Bitcoins, creating the digital codes that they need.
01:26It's an approach that could have merit for other types of industry.
01:30If you can harness the waste product from the Bitcoin miners' heat, then why not?
01:34A process that's getting results bit by bit.
