Laser Coffee

[Omega]

Not sure if you guys have seen this before, i stumbled across it.
I dont care for coffee, but this is a good idea

It was a little blurry but I'm pretty sure that said 2.5 kW Continuous Wave.



Pretty sweet.

Yep, I've seen it. If it is 2.5k, That's equivalent to five microwaves.

only if you have an old microwave (mine's 1200w)

but yeah it's an old video but awesome nonetheless

very nifty way to warm up the drinks! i need to take one of those snowboarding with me so i can make hot cocoa on the go

just need a hand held one lol

I already heard around about TEA lasers ;D

A 2.5 kilowatt handheld continuous laser. Now what a brilliant idea

Of course, you have the technology to do this? Right? That's why you suggested it? Right? RIGHT?

just as soon as battery technology improves a little.. And they finish that trans-dimensional portal that can be used to evacuate all the heat from the little pointer.

Yeah, I've seen that one before - bet that "coffee maker" is way more expensive than any fancy model you'd ever find in even the ritziest department store!!! ;D

But seriously, being that's a YAG, it's a wonder it didn't just burn right thru the bottom of cup that only had the water in it - that wavelength goes right thru clear water.....though the beam didn't appear to be tightly focused, maybe that's why...

;D ;D ;D

 

[Midknight]

What wavelength do you start getting into microwaves?

haha, you get +5 awesome for that.
shame on myself for not thinking of such a good pun first

Microwaves have a wavelength of about 1mm to 10cm.

only if you have an old microwave (mine's 1200w)

Like most energy emitting devices, microwaves are rated on input power. Lasers are rated on output power because of the many many ranges of efficiencies encountered in lasers. It wouldn't make any sense to give a CO2 a rating of 300W and an argon of 10KW if the CO2 output much more. Magnetrons are about 65% efficient. Most small/medium 800W microwaves only emit 500W of energy.

But seriously, being that's a YAG, it's a wonder it didn't just burn right thru the bottom of cup that only had the water in it - that wavelength goes right thru clear water.....though the beam didn't appear to be tightly focused, maybe that's why...

I think what's happening is the beam is focused and ultimately diverged when it enters the water and heats the bottom of the (ceramic?) cup which inherently transfers the heat to the water.
