I think the fundamental problem with waking up has little to do with the power of the alarm clock. If the alarm clock could detect the sleep cycle pattern, it could wake you up when you're not in REM sleep so that you wouldn't wake up groggy.
When you get into a very rigid sleeping schedule, the REM cycles are more rigid as well and you'll tend to wake up less groggy since you're able to position your REM sleep cycles away from the wake up time. Waking up properly also doesn't require a clock that runs away from you.
So there's 2 ways to solve it: get a smart alarm clock that can predict/measure your sleep level, or fit yourself into a rigid sleep schedule for a long time so that your body adjusts to it.

I actually saw an alarm clock that did that (detected REM sleep), but I think it was a demo, and not a commercial product.
Maybe make use of OpenEEG and build one.
