Yep, mining for cryptocurrency can now heat your home

French startup Quarnot recently unveiled a space heater that could potentially pay for itself — someday. By harnessing the massive amounts of heat GPUs generate while mining cryptocurrency, Quarnot’s QC1 heater will not only keep you toasty during the winter months, it could very well earn you a little extra cash.

“The heat of your QC-1 is generated by the two graphics cards embedded in the device and mining cryptocurrencies or blockchain transactions: While heating, you create money,” the QC1 product description reads. “You can watch in real time how crypto markets are trending, on your mobile app and on your QC-1 LEDs.”

Really though, the QC1 heater is a slick-looking device, and it packs some serious power — two AMD Radeon RX 580s — but it retails for $3,600. That is a huge amount of money for what amounts to a space heater, even if it can mine cryptocurrency. Keep mind, that is all it can do, it doesn’t include a hard drive or an operating system. You control it from your phone. It can’t run games, it can’t be used to check your email. For that price, you could just buy a high-end gaming PC with two comparable cards inside and set them up for cryptocurrency mining yourself.

Let’s do a little math. You would have to run the QC1 all day every day for five and a half years mining Ethereum before it paid for itself, at the most recent Ethereum exchange rate. The real story here isn’t the QC1, it’s the fact that it exists at all. Using excess heat from cryptocurrency mining to heat your home is actually a really great idea. Mining cryptocurrency generates a tremendous amount of heat and putting it to good use could make passively mining cryptocurrency more approachable.

Nobody is going to buy one of these things and strike it rich, that part of the cryptocurrency boom is probably over, but as a proof of concept, the QC 1 is a fascinating product. Waste heat has always been a huge issue for server farms, and even offices that run a lot of desktop computers, putting it to use in the home isn’t a bad idea. But at $3,600, it’s not a good one either.

SimpliSafe is now using AI to prevent burglars from entering your home

SimpliSafe rolled out the Smart Alarm Indoor Camera in 2023, which coupled AI technology with live monitoring to better protect the inside of your home. The company is now looking to expand those features to outdoor cameras, with Live Guard Outdoor Protection rolling out to early access users before seeing a full-scale launch later this year.

Live Guard Outdoor Protection works much like the Smart Alarm Indoor Camera does, though it's been modified to work outside. When your system is armed, cameras equipped with Live Guard Outdoor Protection will use AI to identify threats on your property. If AI finds something suspicious, the event will be escalated to SimpliSafe's professional monitoring team, who can then intervene via two-way audio to let the intruder know they're being filmed. They can also trigger a siren or request police dispatch.

Horizon Forbidden West is a marvel — if your PC can handle the heat
Aloy shooting a bow in Horizon Forbidden West.

More than two years after its release on PS5, Horizon Forbidden West is now available on PC. The original game, Horizon Zero Dawn, has become a mainstay for performance testing on PC, and it's one of the pillars of our GPU reviews. The sequel ups the ante in a big way with more graphics options and a more demanding world overall.

I've been playing the game over the past week, drilling down on the best settings, comparing DLSS, FSR, and XeSS, and testing the bounds of performance. Horizon Forbidden West lives up to the standard set by the original release, though weaker GPUs with only 8GB of memory will struggle with high graphics settings and resolutions.

Apparently, ants can eat your GPU now
Nvidia GPU core.

Every few months, a post pops up on one of the various subreddits I follow with a desperate user showing off horrific photos of ants crawling around inside their gaming PC. That's exactly what happened to u/Thejus_Parol, who posted on r/pcmasterrace with some true nightmare fuel (spotted by Tom's Hardware).

In this case, pesky fire ants made their way through the dense componentry of the graphics card, ending up at the GPU itself. As is usually the case with these stories, the ants started eating the thermal paste on the GPU core and the thermal pads on the VRAM, causing temperatures to spike. This is usually the first indication of a problem. As the user says, "I noticed that my max GPU temps were rising a bit. When I checked if the fans were spinning correctly, I saw ants marching on my GPU and on top of my case."
