About a year ago, I first talked about the Aeromine rooftop wind turbine and its unique “motionless” design. Now, a new rooftop turbine is hitting the scene. Norwegian company Ventum Dynamics just released its shrouded wind turbine, the VX175, to the market in February.1 It’s also deployed in
Where I live in New England in the winter it can get as low as -13 F (-25 C). During summer heatwaves, it can reach over 100 F (40 C). Many of our houses and homes weren’t built for that, and in the United States, we aren’t exactly
Did I get ripped off and scammed with my solar? According to the comments on my recent solar panel video, where I compared a Tesla Solar Roof to my more modular solar panel system, I surely did get scammed and ripped off. … but did I? The critical comments really boiled
Perovskites are often hailed as the next big thing for solar panels. They’re more efficient than silicon PVs could ever be, and they have higher yields. However, their fragility and short lifespans have relegated them to the lab…so far. But 2024 is looking to be the year of
If your taste in TV is anything like mine, then most of your familiarity with what analog computing looks like probably comes from the backdrops of Columbo. Since digital took over the world, analog has been sidelined into what seems like a niche interest at best. But this retro approach
Sand. It’s coarse, it’s rough, and it can make for a great battery. And as weird as that might sound, it’s just one example of the many earthy materials currently used for thermal energy storage (or TES). A while back, we covered the debut of the world’
Some of you may have seen Marques Brownlee’s video from a few months back about how he hasn’t paid for electricity in a year because of his Tesla Solar Roof. But…this got me wondering why I’m still not seeing a lot of Tesla Solar Roofs around.
Hydropower is a great source of energy that doesn’t suffer the same intermittency problems as other renewables. But dams fail. A lot. About 95% of the existing hydropower systems in the States were built before 1995, and over half operate using equipment designed over 80 years ago.1 This
Today is a really hot topic: water heaters. No, it’s not sexy, but water heater technology is kind of ingenious with its simplicity. A typical electric water heater has two heating elements; one near the bottom and one near the top, all housed in a very well insulated cylinder.
Airships: the number one sign that you’re in an alternate universe, or a Miyazaki movie. While they may seem like a bad idea, because they’re not as fast as planes or as powerful as freighters, airships actually sit in a goldilocks zone in between them. There are some
The Apple Vision Pro has a lot of hype, a lot of negativity, and a lot of snarky hot takes on social media surrounding it. Depending on who you listen to, it’s either the AR/VR headset that’s going to revolutionize the industry and the way we work,
You’re probably used to solar installations that look like this – solar panels facing up towards the sky, which makes sense. You want a wider area to catch more of that sweet solar energy, right? However, bifacial vertical solar panels have started to gain traction recently. Their more flexible-footprint has
