Europe is going to be a hotbed for Bitcoin mining at home

Maximilian Obwexer faced a dilemma. 

Heating his Austrian home with heating oil was very expensive. He was a tinkerer and former hydroelectric plant engineer who wanted to figure out a cheaper way to heat his house. 

He founded his company three years back after many attempts at mining bitcoins. 21energy makes beautiful, well-balanced and sturdy (and very quiet!) miners. The home version of miners. Early models of Ofen 1 The standard model reached speeds of up to 10 TH/s while the high-end version could achieve, with a lot of speed, and noise levels, 40 TH/s. After hiring only 12 new workers this year, and launching a new product line in 2016, the company has increased production. Ofen 2 (35-42 TH/s), the Bitcoin heater comes in the style of a conventional radiator — powered by Bitcoin. You can. solo mine with this bitcoin heater… or join whichever pool What do you think would be best?

“Bitcoin heaters are decentralized grid balancing — at home!” On Friday, he announced this on stage before the curious faces of the hundreds in attendance at the first Nordic Bitcoin conference BTCHel. He spent the majority of his speech on a positive note. You can also check out our other blog posts. By demonstrating his product or selling it, he can explain his story in Bitcoin, but the numerous problems that plague the European grid.

Europeans are reliant on foreigners to import energy. Its current electricity producers — legacy coal, gas and hydro — are increasingly asked to turn off their supply to the grid, in favor of the ever-more present wind turbines and solar panels. The fossil-fuel based power generation emits CO2 and particles into the environment. But its replacements are more dynamic. uncontrollable electricity Generation onto the grid. Even renewable energy producers are required by the grid to reduce or stop production when demand is at its peak. There simply isn’t anyone to accept excess electricity and nowhere else to store it.

It is bad that electricity is wasted, but it is even worse that the calculations of renewable energy investors are affected. Then, you can learn more about the problem.. Not unrelated, households in Europe pay exorbitant rates for their electricity… and on top of that, heating in general is quite expensive.

The old world seems to be a relic when all these aspects are combined Out for Bitcoin mining. Obwexer is in agreement. “It’s a no-brainer — even if you don’t like or understand Bitcoin,” Standing next to his green shiny booth, and the radiators which keep the Expo hall of Helsinki warm. 

In fact, many of his clients are “solar guys” — devoted climate change activists wanting to do something hands-on to de-fossilize their own energy use. Bitcoin may not be the first thing that comes to mind when thinking of groups interested in Bitcoin. “The economics just make sense,” Obwexer tells me. 

Recent studies have shown that the number of people who are able to speak English is increasing. podcast interview Obwexer commented that Knut Svanholm, Luke de Wolf are two of BTCHel’s co-organizers. “Finland is really at the forefront of bitcoin heating and bitcoin district heating”:

“Europe needs Bitcoin mining so badly, with the high volatility in the electricity grids… we don’t have to fear the politicians too much, because… they already wrote it down — they just don’t see that they wrote Bitcoin mining everywhere.”

In Helsinki, the graph he displayed was one of the key ones in the economics debate. This illustrates how important energy is in a modern society. “If you want a clean, rich, healthy society you need a lot of power.”

Obwexer, and the team of 21energy’s will be contributing to flexible grid load shedding. Putting mobile miners in a truck and take production pressure off, e.g., hydro plants, is a perfect use case for Bitcoin mining: Instead of being asked to ramp down production because of an overloaded grid, they can divert the electricity stemming from their water flow to Bitcoin miners — which also changes their response time from minutes to seconds.

Next week, 21energy will be at #BTCHEL – the First Large-Scale Bitcoin Conference in the Nordics! ⚡
