TLPTPW - The I think the end is near edition

Like i understand that through thermodynamic reactions in the different levels of our atmosphere is how the cumulonimbus is formed, due the the isotopic reactions of the hydrogen and  oxygen  molecules being heated from wind temperatures, creating enough of a reaction to cause the area of effect to form the vapour to collect and then fall back down. But my curiosity is if this same thermodynamic reaction could be manipulated  through say, the gathering of a crowd at a venue, I got this idea while at a concert once,  I was sitting there on a nice bright sunning day, and while having a meal between sets, I was watching the sheer number of people creating a vapour like smog, and I thought to myself, imagine if all that energy could be harnessed, collected and accumulated, and this thought was buzzing in my head thinking about the different scales of said reactions through the formulation of cumulonimbi, low and behold, not long after a cloud emerged and then a beautiful moment of a very short lived very quick sun shower hit us. And I just lost myself for a moment. My contemplation with this is due to the nature of water having vibration properties could not that same notion very well be the manipulation of the heat variance creating just the right situation for such an event to take place??
