Hello to all; my first post here. Have been lurking for some time and the fabulous debut of the Model 3 motivated me to register and join the fray. Have not yet reserved a Model 3 as due to my height (6'4") I need to test drive one first. Will also want a service center closer to my house than 50 miles across town in heavily congested freeway corridors. But I sure like what I see in the car so far! My long term goal, as my user name implies, is to be free of fossil fuels in personal transport for my wife and I. We are also moving our house toward a minimum grid impact/net zero direction with building envelope enhancements and eventually solar. That said, I do HVAC for a living (heating and air conditioning) from teaching HVAC design to overseeing operation and installation of HVAC controls for a large state university campus. During the Model 3 debut one of the first things I noticed on interior shots of the car was the absence of conspicuous dash a/c air outlets. Nor did I immediately see slot diffusers for windshield defrost. I have heard various chatter about "Dyson" type air distribution from the dash; perhaps a continuous slot diffuser marching horizontally across the dash. With the prominent landscape oriented center screen shown, replacing the traditional location for a center stack with dash outlets, this makes me wonder how well conditioned air will move through this car. Car a/c (in cooling mode) in all other cars is largely spot cooling from concentrated blasts of air from the dash vents, with ambient (surrounding air and surfaces) cooling a secondary benefit as the car cools down on a hot day. If the Dyson diffuser has no way to direct or deflect a concentrated blast of air onto or away from a person, it makes me wonder if we're looking at a potential disappointment in HVAC performance (in cooling mode particularly). I want to believe that rather than this being the case, the Tesla design team is once again leading the way by making disruptive design changes that actually work. Personally, with some exceptions, dash vents in most car interiors are rather ugly. Since I live in hot, humid Texas, a great a/c is one must have in any car purchase I might consider (as well as being able to fit in the car! ) I look forward to someday when my local Tesla store has one parked out front that I can test drive!
