Elon Musk Says Tesla Will 'One Day' Produce 'Super Efficient Home HVAC' With HEPA Filtering (techcrunch.com) 85

Posted by BeauHD from the perfect-for-wildfire-season dept.
An anonymous reader quotes a report from TechCrunch: Elon Musk has previously touted the "Bioweapon Defense Mode" boasted by Tesla's vehicles, which are designed to provide excellent air quality inside the car even in the face of disastrous conditions without, thanks in part to high-efficiency HEPA air filtration. Now, Musk has said on Twitter that he hopes to one day provide similar air filtration along with home HVAC systems.

Tesla, while primarily an automaker, is also already in the business of home energy and power generation, thanks to its acquisition of SolarCity, its current production of solar roofing products and its business building Tesla batteries for storage of power generated from green sources at home. While it hasn't yet seemed to make any moves to enter into any other parts of home building or infrastructure, HVAC systems actually would be a logical extension of its business, since they represent a significant part of the overall energy consumption of a home, depending on its heating and cooling sources. Boosting home HVAC efficiency would have the added benefit of making Tesla's other home energy products more appealing to consumers, since it would presumably help make it easier to achieve true off-grid (or near off-grid) self-sufficiency.

        Um... Not really pumping heat/cold into the ground to store it... Just using the massive heat sink that the earth's crust is to be more efficient. The thing is that the temperature gradient between underground temperature and room temperature is nearly a constant year-round and is usually less than the outside air to inside air gradient. That makes the pumping of heat more efficiently than a system using outside air.

        So you are not storing anything really, just using the massive heat sink.

    This is a huge problem:

    An estimated 4.2 million premature deaths globally are linked to ambient air pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections in children. Worldwide ambient air pollution accounts for: 29% of all deaths and disease from lung cancer.

    However, it seems like limiting this pollution at its sources (energy production, cars...) would be far preferable to trashing the environment and forever sheltering indoors with filtered air (for those wealthy enough to get it).

      Agreed, and HVAC with HEPA filters already exist.

      There is nothing special about the Tesla "bioweapon defence" mode. It's literally just a standard HEPA filter and a button that turns the fans on to maximum.

        That was my take, too. What is so new and different about HEPA filters? I already have that in my HVAC, along with a variable fan, variable compressor, and smart thermostat. The fan runs on low speed 24/7 when not in higher speeds for cooling or heating.

However, even the low concentrations we have now are still dangerous, and the impact for a long time was somewhat underestimated.

    I think Elon is going to find disrupting the HVAC industry is considerably more difficult than the auto industry. Elon had an "easy in" with the auto industry because no one had filled the electric car segment. All of the auto manufacturers have looked at Elon's money losing venture. And lets be truthful, it has only recently started to break even, but its quality of manufacture in comparison to the established car manufacturers still has a ways to go (and they still have a fascination with touchscreens which have no place in the cockpit of a car).

    The HVAC industry is very competitive and has been undergoing horizontal and vertical consolidation in the recent years in order to improve efficiency across the board.

    Unless Elon comes out with a brand new whiz-bang air conditioning technology (and believe me, there are many many companies working that angle) that significantly improves the efficiency of cooling air to the point where water condenses out of the air, I expect that Elon trying to break into that market is going to be significantly harder.
    • He's going to need a "crack" team of HVAC installation guys, for one thing.
    • HVAC is already a solved, known issue where better = more air resistance = more energy and noise and blockages. Per sawdust mills aka where Dyson flogged the centrifugal force concept, all you can do is gang stages or add electrostatic pre filtering and self cleaning. The Japanese have nailed air ionisers/filters for the house. Musk needs to re-invent a roomba like cleaning snake to clean dirty HVAC air ducts, and maybe some solar heat exchanger mass better than aluminum fins.

      • Per sawdust mills aka where Dyson flogged the centrifugal force concept

        I was under the impression that cyclone filters in saw mills and workshops were already a thing long before Dyson "invented" it. Same for the bladeless fan and airblade hand dryer, I might add, he didn't invent those either, merely improved upon them and marketed the crap out of them.

        But that wasn't an idea that nobody had had before. It was the way rocket ships worked in science fiction all the way back to the 1920s. McDonnell Douglas had a demonstrator (DC-X) back in the 1990s, but it never went anywhere because funding ran out after sixty million (about a hundred million in today's terms).

        The trick in technology isn't having a good idea, it's knowing when the time is right to put money into an idea that's already floating around. Timing was Steve Jobs' superpower; he never *invent

        There is the pesky problem with the laws of thermodynamics and how they apply to HVAC systems. It would be very nice if Musk could break a couple of those laws, but somehow I don't think he can, even with the full force of his personality.

        HVAC systems are pretty much bumping into the theoretical maximum efficiency you can have now. There may be some improvements in compressors and heat exchangers to be had out there, but I seriously doubt any real breakthrough technologies remain in the industry. The eff

      The High Efficiency in the acronym HEPA is about the percentage of particulate matter it captures. Doing HEPA-level filtering with less ENERGY spent pushing air through the device (or whatever) gives you a whole 'nother aspect to be Highly Efficient about.

  • The control of most HVAC systems is still pretty crude. A thermostat turns the heating or cooling on or off. There might be two stages to the compressor, but that's it. With electronically commutated motors on all the compressors, fans and pumps, huge gains in efficiency are theoretically possible if you optimized the speed of and power going to each and also optimized cooling vs. dehumidification, etc. You could integrate HVAC with hot water and perhaps even refrigeration for additional energy savings.

    They're ridiculously efficient. You don't use regular HVAC duct, you just need space for the refrigerant lines. And all the heating and cooling is taken care of by air handlers in the main common spaces and bedrooms. As it's just a heat exchanger, it's power efficient, space efficient, and if you use HEPA filters, quite clean.

    You then handle the home's fresh air needs with a fresh air system, ERV/HRV and a humidifier/dehumidifier. Again, HEPA filtered.
