Power Meters Heartrate Monitor
I came across the Powercal Power Meter device when I was looking around for a power meter. It is a heartrate monitor strap that extrapolates power based on (I can only assume) change in heart rate using some form of algorithm. There is no direct power meter on a hub, ledal or crank - its only input is heart rate.
What a load of rubbish I thought.
Then I read the comparison below where the Powercal heartrate power monitor was compared with a real power meter.
Stationary bike power
Because of injury i've been training on a stationary bike at the gym. Just wondering if there is any guide for power or if its pretty irrelevant?
Due to my supreme lack of fitness i can hold around about 125 watts for about 10minutes at rpm of 90-95.
Power Output
Warning: Nerd content (and probably inaccurate at that) below!
Just now I was pondering efforts at the Quarry Climb and was curious as to what amount of power is being put out on that climb. Yes, yes, have some time this morning... 
Anyhow, so I start with basic fizziks:
1. Power = work done / time taken
2. Work done = force on object x distance object is moved
3. Forget anything fancy (as I don't know)... force on object = mass x gravity if you lift it in a straight line.
