Calorie expenditure calculations?

[kfergos]

There's some calculator online somewhere that lets you plug in your weight, the bike's weight, the wind speed, elevation gain, power output, whether you've shaved (just kidding)... and it makes an estimate for you... this might not be much less accurate than a GPS/hrm, given how many variables and fudge factors it seems there are...

Anybody know where this online calculator might be?

I find lots of vague ones that ask for your weight, how long, and generally what activity. They're not really very helpful because it doesn't take into account your amount of effort and so forth.
