Unfortunately, storage of electricity is quite difficult; supply and demand therefore need to be balanced at all times. An oversupply (ie, overvoltage or excessive frequency) will damage equipment, so prices go negative to encourage those p

The NYSE is one of the stock market centers in the US (yes, there's more than one). It's a place where you (usually virtually these days) go to agree with someone on the specifics of the trade - buy 100x GME at $420. The DTC is in

Converting between different grid frequencies would need a rectifier/inverter or rotary converter - and one that can handle high power (1200W+ sustained) as well. That's quite a bit of equipment to run just a microwave... Edit: Lo
