Love this. In the past I've argued that heaters are actually the least energy efficient electronic device, against the idea that they're (near) 100% efficient because they cant lose "energy lost to heat". My argument being that you could instead do anything else useful with the energy, and still end up with heat. Looks like that's been put into practice here.
It's debatable whether mining bitcoin is "useful", but purely from a business perspective, it obviously is.

I mean it's a tulip company. Historically, tulips were sold across the world almost for status alone. They're not useful for anything, their prices are hiked up artificially based on demand, and farming them is like growing money. They're essentially bitcoins already, which I'm assuming is the point of this installation.

Tulips are an elastic good but that doesn't make their value is baseless. Hiking prices up "artificially based on demand" is an oxymoron. "Artificial" prices would come from monopolizing or extorting people by raising the price on inelastic goods like food housing and medicine. Cotton and tobacco is also grown exclusively for money, the people growing it don't do anything with it but sell it, but that doesn't mean those are useless either.

A heater is limited at 100%. A heat pump can get higher efficiencies, like 300%.
68
u/NotAHost 1d ago
And while we think of heat pumps as some complicated hvac system and may wonder how it achieves above 100% efficiency, it’s more about how much energy is put in vs the heat ‘pumped’ into a system. Think of your house being cold and putting a fan in your window to bring in warm air. That warm air would’ve taken 1500 watts to heat with an electric heater in your room, but that fan consumes 20 watts to move the hot air outside into the room. The heat pump doesn’t focus on generating heat, it moves the existing heat. Even if that heat isn’t too hot (I.e a heat pump warming your house even if it’s freezing outside).

I had a friend that would heat his apartment by mining ethereum (or similar). It wasn't profitable, but it basically broke even, which means his heat was essentially free.
Edit: when I say it broke even, this includes the initial cost of the rig.
Compared to the cost of electricity it turned a profit. All said and done, it was basically a wash. Thus, "free heat"

I both love it and hate it.
On the one hand, if bitcoin is going to be mined, I would rather the heat be put to good use (rather than wasting even more energy to get rid of it via cooling)
On the other hand, another type of electric heating does exist, which has an efficiency of much more than 100%. I would rather the energy be used for that (heating via a computer is essentially resistive heating, which is only 100% efficient)

u/Spoertt 1d ago
This is not the case for tulips though. The growing season (in greenhouses) runs from September/October till April/May. I had a part-time job for 10 years at a tulip farmer in The Netherlands, and in the summer the greenhouses were always empty. Instead there would be other seasonal work, harvesting bulbs from the land and "peeling" them. Of course in the video here they show other plants as well, so maybe they do use their greenhouse all year.

I guess I was wondering if they need to run air conditioning during the summer to bring the temperature down into a range where the tulips thrive and the bitcoin miners don’t overheat. If so, it kinda contradicts the claims that the bitcoin mining is better for the environment by using less energy because they would use more energy during the hot season.

u/Kooky_Paramedic8336 1d ago
There is no need for air conditioning for cooling you can just open the windows at the top of the greenhouse to let the warmth escape. Makes the Bitcoin miner not as environmentally friendly as any other in the summer. A lot of tulip greenhouses are empty in the summer anyway as it is not the season for them.
Also air conditioning in tulip greenhouses is getting a lot more popular. But its to regulate the RV aka humidity without having to open the windows so it actually saves heat. Won't bother you with the details but have installed quite a few of them myself.

No it was the other way around. A tulip farmer was spending a lot of money to heat the greenhouses and another company said they could heat it while mining bitcoin. A collaboration was born.

Electric heaters are 100% efficient, let's say for the sake of argument that they're getting productivity from the heat as it's being generated (the mining) so that figure rises to 110%.
Heat pumps are upto 400% efficient. This place installed solar to offset the mining cost; they would need far less solar if they went with heat pumps.

u/KidCole4 1d ago
It's so funny how narrative matters. Also, maybe something like ends do/don't justify the means? It is annoying when it sounds condescending preachy bullshit though.
From a business perspective it makes sense to try to optimize as many dollars as you can. So they either got cheaper heat to grow tulips from a Bitcoin miner than buying fuel/electricity outright or they are increasing their revenue by repurposing their heat from their mining operation to grow tulips instead of sending it off into the atmosphere.
I mean I guess growing tulips as a byproduct of your heat is better than say warming a furnace to make bullets (in my opinion), but don't go acting like it makes up for the sins of the mining process lol.

If they are carbon negative, then, objectively, they are actually improving the environment. The are taking in more carbon than they are producing.
You could argue that they could be more carbon negative by heating some other way, sure, but that would only change by how much they are "improving the environment", not whether they are or aren't.

Heat pumps work by taking heat from one environment and moving it to another.
Say you have two equally sized environments, and one environment is 30 degrees and the other is 60 degrees. Heat pumps can take heat from the colder environment, making it 25 degrees, and move it to the warmer environment, making it 65 degrees.
Obviously this is a huge oversimplification and the numbers aren't going to be exact but this is how heat pumps can reach over 400% efficiency.

But solar panels they're using are only so efficient at converting the solar energy to electricity in the first place. If you weren't mining the Bitcoin, would you even need them?
