As mentioned, it handles large temperature swings better than the more common soda lime glass. This can be useful if you have say a casserole in a glass dish that you prepped and stored in the fridge or freezer. When you go to bake it, if y

RFID can still use batteries (called active vs passive RFID) for what it's worth.

Active RFID tags with integrated sensors are becoming more common. Electronic sensors of various sorts have become low enough power to enable embedding a very small battery with sensors and RFID transmitter. These can log readings every sec

Certain things get a lot more complicated when you go from AC to DC. Two of the most significant issues for home use are connects that can be disconnected under load (arcing is a serious issue here) and turning DC power on/off with mec

This has absolutely nothing to do with material build up and drought conditions that exacerbate extreme forest fires. What you linked is weird propaganda about Finnish forestry companies trying to utilize clear cut areas more effectively.

I've had major issues with the couple USB hubs I have purchased from them.I've totally written off their hubs at this point. It's been disappointing since their cables, chargers, etc have been pretty good.

Apple (and most high end tech designers) use highly specialized, very $$$ PCBs for a lot of their products. They aren't created by traditional litho + etch, but rather by a process called modified semi-additive processing (mSAP). iPho

There are plenty of things that have firmware, but run it out of RAM. FPGAs do this, and some microcontrollers. Dialog, now Renasas, has microcontrollers that run their firmware out of RAM. Commonly there is a hardware peripheral that pulls

I'm 100% certain you are mixing up poison oak and poison ivy. People do this non stop here in the midwest, but in the reverse of what you're doing funny enough. Check this page out for a map of known ranges of each species: https

If you're knowingly measuring a 50 ohm resistor with a VNA you're either calibrating it, or need to do more reading about a VNA.

Farmland in the midwest has been shrinking consistently for decades. Your comments would make sense if the opposite of this were true, and there was demand for additional farmland, but there isn't. Ohio reduced the amount of land it ne

No, but installing an maintaining diesel tanks and pumps ain't cheap either! Especially if you have to deal with any environmental destruction caused by spillage or leaking tanks (happens way, way more than most people think).

You're talking about battery cells, but you need to look at the battery _pack_ energy density. The model 3 battery pack, which uses the same cells as semi, is about 170Wh/kg. The numbers in TFA are very reasonable estimates.
