Strain gauges or GTFO
Algorithms (such as my elite superchono fluid trainer) have little to no accuracy...no matter what algorithm or who made it. The closest would be the new system from Cyclops/Saris which takes a zero based on hr at a given measured power output, then bases power measurement off hr on the road.
Or they are totally realistic and I can do 6.6 w/kg for 2 minutes.

Because you don't REALLY think a HR-based power guess is more accurate than a power calculation actually based on physics, now do you?

Heart rate and power simply aren't that connected to make measurements that way.
There are too many unknown factors, like whether or not you had a nice Belgian Triple just before your ride or not

Phil Gaimon had a great flow chart on why you don't want to reveal your power numbers in public.
Essentially it goes something like this:
None of the end points on the flow chart tend to reflect well on the poster.
Essentially it goes something like this:
- if your FTP is lower than others; you're weak and you suck
- if your FTP is high, either you're fat, and you still suck
- or if it's high and you're not fat, then you race stupid given the lack of results with your power.
- or your FTP isn't as high as you claim

dude, you forgot to include the fact that you used your massive guads to drope the hamer on the fool somewhere in your post. Without that or getting bear hugged by a convenience store security guard, you fall short of the requirements needed to start a flameworthy thread on the 41.

Cyclops claims its within 5% of actual results, averaged over the whole ride. Obviously on a micro level it's going to be useless, but for calculating TSS acculumated over a ride I think the heartrate power strap will be very useful. I could see roadies using these when they're on their mountain bike so they can get a decent TSS figure. Time will tell how well the tech works. As long as the price is accordingly low I think it's a nice addition to the power meter lineup.

Average power over a complete ride ... okay maybe at 5%, but that's hardly a usable figure, is it?
Now that I'm getting into tri's I've started looking at heart-rate monitors with gps for speed and distance that are usable while running and cycling alike.

As I mentioned before, it'd be usable for calculating TSS which could help track training load and training stress balance. I'm guessing most people wont be using it in that way, but it's certainly a possible legit use of the tech.

Bummer to learn that the "a**hole roadie" phenomenon isn't only occurring in the US.
