I'm curious if anybody here would have any thoughts on a counter-intuitive device which I am considering figuring out. No this isn't an exercise in practicality. How would one construct a device that plugs into an AC outlet that would waste 1500w of power?

What does the device do? If it does nothing, probably it is a heater.

power=sq(Voltage)/R
calculate Resistance(R),
and then dissipate..this is the trickier part..if it doesn't get dissipated say goodbye to the resistor or fuse.

Nice but how would I dissipate that amount of juice? That's essentially what I'm trying to figure out. LOL. Is there any way to dissipate that amount of juice as EM radiation as opposed to heat? I'm aiming for (in order of preference):
cheap as possible
compactness
durability

It's hard to believe making something that doesn't work well could be so friggin hard!!!

A 1500 watt lamp puts some energy out in EM radiation. The heat generated is another form of EM radiation. From that, a 1500 watt heating element would be good.

It dissipates in the form of heat. If it doesn't produces sound, light or other forms of usable energy, then all the energy is wasted to produce heat. It is a heater, basically.

It could be a toaster (a very powerful one).

It is more correct to say that a form of EM produces heat by the means of radiation (or that a form of EM radiation is also a form of heat). There are three types of heat transfer: radiation (EM), convection and and conduction.

Plug in a couple of 750W hotplates.

Once you have 'em warmed up, fix me some coffee and make me some chow.

I have a 1500W oil heater in my house, as a matter of fact. There is no need to use it outside, as it is not that dangerous!

What are you going to do with this device? For how long will it be on?
