No.

Sand to wafers… Fortunately, there is no shortage of raw material. Silicon is the second most common element in the earth’s crust, comprising about 26% and exceeded only by oxygen at 49%. But silicon does not occur naturally in the pure form needed for electronic applications, for which it must contain less than one in a billion non-silicon atoms. The starting material really is sand. Not just any sand, but silica sand, specially quarried for this purpose and having concentrations of quartz (silicon dioxide) as high as 95%.

Probably not a well received opinion but the amount of China promoting drivel that goes on here in lemmy is astounding.


The bottleneck is the extrusion and the cooling of the extrusion. Not the transport system.


Prevent sensor sync when not connected to wifi?
As the title says, I currently don't have a reliable method to connect to my home network due to pivpn having issues. In the mean time my phone trys to synced sensors constantly and is one of the power sinks. Is there a way to turn off sync when I am not connected to wifi or even better when I'm not at home?
