Maximilian Obwexer had a problem.
He heated his Austrian home with traditional heating oil, which was expensive. A bully by nature, the former engineer was working on hydroelectric plants, and was trying to find a better way to warm up the house.
After delving into many rounds of experimentation and rabbit holes in Bitcoin (mining), three years ago he founded a company dedicated to this effort. His company, 21 Energy, creates miners for use in the home, balanced, sturdy, incredibly beautiful (and incredibly quiet!). The initial model of OFEN 1 boasted the maximum 10th model, allowing it to reach the premium model at top speed, and was able to fully measure the 40th noise. With production expanding, hiring 12 new employees this year alone and launching the New Ofen 2 (35-42 Th/s), the Bitcoin heater will be offered in the style of a traditional radiator equipped with Bitcoin. And yes, you can solo mine with this bitcoin heater… or join in which pool you think is the best.
“Bitcoin heaters balance a decentralized grid – at home!” he declared hundreds of curious faces of the audience at the first Nordic Bitcoin Conference Btchel on the Helsinki stage on Friday. Refreshingly, he spent most of his presentation do not have He sells his excellent products and explains his story in Bitcoin, but about the many troubles that plague the European grid.
Europeans are seen by foreigners to import energy. Current electricity producers, Legacy Cole, Gas and Hydros are increasingly being asked to turn off supply to the grid in favor of current wind turbines and solar panels. Fossil fuel-based generations generate CO2 emissions and particles in a direct environment, but the proposed exchange pushes dynamic, uncontrollable power generation into the grid. At peak supply, even renewable energy providers are asked by grid managers to reduce or reduce production. No one takes up any extra electricity.
This is clearly a bad thing in terms of wasting potential electricity that can be used, but even worse, it is investing calculations for renewable energy investors. bad. Not unrelated, but European households pay exorbitant fees for electricity…and on top of that, heating is generally very expensive.
To sum up all these aspects, it is the old world shout For Bitcoin mining. Obwexer says, “Even if you don’t like or understand Bitcoin, it’s easy. Even if you don’t like or understand Bitcoin,” he says.
In fact, the majority of his customer base is “solar guy.” Climate change activists want to do something practical to dissect their energy use. It’s not the first group to think about your interest in Bitcoin, but “economics just makes sense,” Obwexer tells me.
In a recent podcast interview with Knut Svanholm and Luke de Wolf, two members of Btchel’s joint organization, Obwexer said, “Finland is really at the forefront of Bitcoin heating and Bitcoin district heating.”
“Europe needs Bitcoin mining Awfulthere is a great deal of volatility in the electric grid… there’s no need to be too afraid of politicians. Because they’ve already written it down.
On the Helsinki stage, he presented one of the most important graphs in the entire discussion of economics and energy. “If you need a clean, rich and healthy society, you need a lot of strength.”

Second, his team at Obwexer and 21 Energy contribute to flexible load limiting at the grid level. Putting mobile miners in trucks to apply production pressure, for example hydroelectric power plants, is the perfect use case for bitcoin mining. Instead of being asked to increase production due to an overloaded grid, electricity derived from the water flow can be converted to Bitcoin Miners.
Next week we will meet 21 Energy at #BTCHEL – the first major Bitcoin meeting in Nordic!

In general, home miners in particular are susceptible to the intense economics of Bitcoin mining, which is the case with large mining farms, so using dedicated or reconstructed Bitcoin miners is the most obvious way to diversify mining.
His team at Obwexer and 21 Energy are doing exactly “From Tyrol to World” while solving several real-world energy problems at once.
“I’m very bullish in Bitcoin mining in Europe,” concluded Obwexer.
