Since the launch of World of Warcraft, players have been waiting for and longing to have housing. It still has not happened. The reasons given range from being adjacent to plausible to just feeling outright silly, but the details don’t particularly matter in context; what matters is that we’re still sitting here without housing in […]

As the price of silicon panels has continued to come down, we've reached the point where they're a small and shrinking cost of building a solar farm. That means that it might be worth spending more to get a panel that converts more of the incoming sunlight to electricity, since it allows you to get more out of the price paid to get each panel installed. But silicon panels are already pushing up against physical limits on efficiency. Which means our best chance for a major boost in panel efficiency may be to combine silicon with an additional photovoltaic material.
Right now, most of the focus is on pairing silicon with a class of materials called perovskites. Perovskite crystals can be layered on top of silicon, creating a panel with two materials that absorb different areas of the spectrum—plus, perovskites can be made from relatively cheap raw materials. Unfortunately, it has been difficult to make perovskites that are both high-efficiency and last for the decades that the silicon portion will.
Lots of labs are attempting to change that, though. And two of them reported some progress this week, including a perovskite/silicon system that achieved 34 percent efficiency.

Noted energy expert Marjorie Taylor Greene took to the stage today to deliver one of her famous sermons on the mount of ignorance. This time Greene shared an important message for the MAGA patriots who attended her lecture. "If you think gas prices are high now, just wait until you're forced to drive an electric vee-hick-ull," she said. — Read the rest
With OLED-equipped TVs, monitors, and other gadgets slowly becoming more readily available at lower prices, attention is turning to what the next landmark consumer display tech will be.
Micro LED often features in such discussions, but the tech is not expected to start hitting consumer devices until the 2030s. Display makers are also playing with other futuristic ideas, like transparent and foldable screens. But when it comes to technology that could seriously address top user concerns—like image quality, price, and longevity—quantum dots seem the most pertinent at the moment.
