Perovskite solar cells are the best candidate for solving the problem that you pointed out. The best perovskite/silicon tandem cells in the laboratory have 33% efficiency, and the theoretical limit for this type of cell is 43%.

There’s nothing misleading in the study, because they very clearly state the methodology for intangibles, and even provide an alternate calculation excluding it: Finally, net benefits were significantly reduced when benefits were limited t

I don’t usually post a middlebrow dismissal, but using an electric compressor is a fairly obvious idea which often gets discussed and immediately dismissed, so there’s not much interesting here until they reveal more of their design. Typica

Great write-up! Does your pricing plan (“Lifetime Deal”) mean that you will make more money up front, but potentially have to spend more years later to maintain the service even after new signups have declined?

I agree 100%, I think the potential is in a future Vision device which is smaller, lighter, and cheaper, while having an even better display.

The potential of the display is what convinces me that Vision will be a breakthrough device. If Apple has a roadmap to keep scaling up the resolution, while only incurring a fixed manufacturing cost of producing a small 2cm display, there w

From what I’ve read, panels are sometimes only a quarter of the price of a residential solar installation. In that case, if the panel cost twice the price for only 25% more power, it might be worth it.

Does anyone know how good the PowerPC chips from that era actually were compared to the competing chips from Intel? I remember reading a lot of marketing claims, but back in those days there wasn’t so many review sites that would test them

The entire world is going to switch away from using fossil fuels for home heating within the next 20 years, so you should expect to hear a lot about heat pumps going forward. In places like Europe, where gas prices have skyrocketed, the ch
