Who would have thought that microchips would become so cheap? And they are built on silicon crystals. The economies of scale for batteries for cars, phones, computers, will kick in in a way that they don’t for aerospace. Car or phone battery tech will end up in airplanes!
- deepnotderp 7y agoThe amount of silicon in a microchip is tiny. By contrast, single crystal metal alloys for modern turbo fans comprise a significant portion of their cost.
- generatorguy 7y agowell microchips are small compared to turbo fans. Turbo fans are also hollow and inflated via some crazy trade secret process which the Chinese haven't figured out yet, hence them not making their own engines. So the anode or cathode on a battery, or even a whole AA size battery cell, is more on the scale of a microchip than a turbofan blade I think. plus the battery won't have to be subject to the same QA process of x-raying to ensure there are no microscopic cracks or defects. If one cell in your battery pack isn't as good as the rest it will just be managed around instead of subjecting all the cells to insane QA.
