Gandalf, seeing this thread makes me oddly happy. I have been advocating Tai Chi and Qigong for a few months now hardcore, and I was hoping you would take an interest in it. When I do sitting Qigong meditations in my apartment, I usually sit next to the AC vent and turn it up. I exude so much energy that the AC actually ends up blasting non stop, but the whole apartment manages to stay hot. It will cool down again if I stop meditating, and then blast the AC for like 20 to 40 minutes, but thats still amazing. Id like to see a birds-eye thermal view of my entire one-floor apartment building. I am willing to bet during the winter, during periods of meditation, I could save on heating bills by sucking the energy from surrounding units.
