We will know if GM built a bettter car battery in 8 years or so. I am sort of dubious, because it's more like your cell phone battery than a lithium car battery. It uses cobalt. GM brags that their EV battery uses less cobalt "than other EV batteries", but Tesla uses none. We know that Tesla batteries last. It will take a while to know that about GM batteries.
Musk is great. He took a lot of things that everyone knew about and nobody would dare to do, and made them work from a business perspective. We need lots more people like that.
Blast wind: At the explosion site, a vacuum is created by the rapid outward movement of the blast. This vacuum will almost immediately refill itself with the surrounding atmosphere. This creates a very strong pull on any nearby person or structural surface after the initial push effect of the blast has been delivered. As this void is refilled, it creates a high-intensity wind that causes fragmented objects, glass and debris to be drawn back in toward the source of the explosion.
I would think that welds are quite chaotic in nature. The heat changes the crystal structure of the steel, the welds are not uniform, etc.
Steel is really complicated stuff. It's a matrix of iron alloy and hard nonmetallic crystals like carbides. The iron alloy can have five different crystal structures, and can transition between them through heating - which welding does. There is also thermal stress from welding, which you can relax by annealing, but annealing the entire vehicle is not practical.
A blowout on the remains may correspond to this.
Obviously, we need storage for conventional power uses. But desalination that runs on sporadic power? That would be fine.
And backups are not an issue for desalinization. You only need to desalinate when there is power
So it happens that solar and wind crossed the line of being less expensive to sell to California municipalities than fossil-fuel-based power over the past several years. And the perovskite-based cells are looking very promising, and approaching 30% efficiency for tandem perovskite and silicon cells.
Of course desalinization does not have the storage problem that home power does. If you've got more solar power in the daytime, only desalinate in the daytime. And we have lots of desert in which to make that power.
So yes, there is desalinization in the future. I think the real problem, though, is that California has both more people, and more acres farmed, than it can support.
This assumes that the device with the microphone is sensitive to frequencies above the hearing range. Most devices have a low-pass filter for the purpose of avoiding any input above 1/2 the sample rate of the DAC, since these will create artifacts, aliasing, and distortion. Even in the case that current devices have left out the low-pass filter, it costs pennies to add.
The signal does not have to go through an A/D converter at all. Most competently designed microphone systems have a low-pass filter before the A/D, to prevent aliasing and artifacts, and no signal whatsoever will reach the A/D.
Maybe. We've heard the same phrases for Josephson junctions, magnetic bubbles, insert your favorite once-nascent technology here. There is still a big distance between demonstration and practicality.
