comment What is a power meter and why do I need one?
@ChrisCleeland I sort of disagree. I've never been much of an athlete on a bike and a power meter has helped me quite a bit. I got one before I had a TT bike, and this answer, while good in general, mostly addresses the idea that a power meter is only good for training FTP. Power meters can also be used for other things than training FTP -- in fact, training is one of the least demanding things one can do with a power meter.

comment what power did alex dowsett put out during his hour record?
The rider is allowed to receive very limited information, according to UCI rules: pace, distance covered, or time. If the velodrome is quiet you can shout out lap times but generally for record attempts you use a chalkboard -- though of course more recently teams have been using iPads or other tablets. You don't want to give the rider too much distracting information.

A power meter was mounted on the bicycle but according to UCI rules no visible display is allowed so the data are either for review post-ride or can be transmitted to a track side computer for real-time analysis.

comment How many miles of riding require the same effort as one mile of running?
@StephenTouset, I've done a similar thing for short duathlons, where you have a bike leg in-between two run legs. Here's an example of the splits: anonymous.coward.free.fr/wattage/duath-splits.png

comment How can we calculate the efficiency of the Siva Cycle Atom generator?
Crr scales exactly like slope, so an increase in slope of 0.3% is exactly like saying the Crr increases by .003. Regular road tires (not knobbies) typically have a Crr in the range of perhaps .004 to .008 on smooth roads, so using the Siva would feel like switching from low rolling resistance racing tires to Continental Gatorskins (or from Gatorskins to heavy-duty belted hybrid tires).

If you're interested in this question because of its relationship to cadence, perhaps you will want to read this: bicycles.stackexchange.com/questions/12518/…

comment Why am I not seeing improvement in my bike split time?
There isn't enough information in your question to provide a good answer. How did you place on the various legs this year compared to last year? Is the bike leg mostly flat or quite hilly? Except for the aerobars did you use the same bike, same tires/tubes, and same clothing/helmet? Going into T2, where you about as tired both years, or did you feel you had more in the tank starting the run? Overall time improved by 36 minutes, most of which was in running. Did better pacing on the bike improve the run? All of these can affect the SBR splits.

comment Accurately replicating the resistance felt whilst riding via a resistance fan diy turbo trainer
@DanielRHicks, Alex is familiar with the inertial load. Here is his home-built resistance trainer and its flywheel. User95786, here are some estimates of the drag parameters (the "virtual" CdA and Crr) for the Lemond Revolution. Perhaps that will help you in building your own.
