The electronic components that create microwaves (magnetron, transformer etc.) are only 50-70% efficient at making microwaves the rest being lost to waste heat. In order for this device to be 96% efficient they must be capturing waste heat

Again the discussion being resistive versus microwave, restive should be better even in an instant water heater, again microwave has no advantage that I see. And when talking about efficiency you must specify context. In this case heating w

Not going to heat instantly using a heat pump, it would be tank based and it needs solar heated air (warm outside or warm garage).

Why is it less prone to scale buildup? Scale comes from heating the water, which both do. I have a gas instant hot water heater, with a water softener it basically never builds up scale, otherwise a yearly acid flush is recommended and it h

Resistive heating is 100% efficient, they are saying 96% for microwave, meaning you will need 4% more power to achieve the same heating either in a tank or no tank.

Right, trying to see some reason why heating water with microwaves would be preferable to standard resistive heating elements other than for marketing purposes.

Which is why I added the edit. The thing I consider most defining of life is its ability to adapt to its environment both through evolution and later through intelligence and learning.

Direct injection two-strokes like ETEC's avoid the burnt fuel in the exhaust by not injecting any fuel until the exhaust port is closed. They also typically have specific oil injection points reduce the amount of oil needed to be burne

You might be conflating how an injector turns on and if with how the fuel is pressurized. Unit injectors create the high pressure for injection in the injector, combining the high pressure pump and injector in one, fed by a low pressure rai

In many languages like those used to compile to WebAssembly (c++, c#, rust) enumerating standard dictionaries is non-deterministic. A javascript object is a dictionary, it is not surprising that it had an undefined order. If you need order

Many engines have scripting languages allowing modding using full turing complete languages rather config files LUA is a common one in games. Its kinda like the config file vs code as config debate. If I where modding something I would rath

Lasers damage biological tissue in 2 ways, thermal (heat damage) and photochemical which is similar to sunburn caused by guess what high frequency light. There is also acoustical damage which is essentially thermal causing shockwaves from t

This is thermal heating which is the very well known mechanism for non ionizing radiation to affect the body (microwave oven cooking). Cell phones put out about 1000 times less power than your 100w ham radio. Which in itself is not enough

Yeah sorry just not getting it, you can't use SVG's with image tags due to not being able to manipulate them however you then go to PNG's which are even harder to manipulate and are img tags right? At least SVG as images can

IMG tags pointing to SVG's don't have ID collsions since the SVG is in a isolated context, it's opaque to the referencing page because it's treated like any other img reference. We use some server side code to recolor sv
