Correct. Also, if the system design isn't adequate, you can install a system and find that it fails to operate adequately. Then your costs can balloon astronomically. Designing the thermodynamics of the system requires an understand of the thermodynamic properties of the soil that you are installing it in, which of course, will always require models with a degree of error built in.

That's the contractor's fees, not the actual equipment. We put in a DIY system last year and the cold-climate rated system was about $3500. With additional materials, electrician, etc. the total project cost was under $5000. There aren't enough contractors willing to install them and the ones that do are significantly overcharging.

"Game-changing green tech" is here, and continues to appear. Solar and wind energy are the least expensive forms of electrical production in the US. It's often cheaper to build new renewable production than to buy fuel for existing plants. Electric cars are hugely more capable than those of 5 years ago. You are just moving the goalposts. And technology changes incrementally, not revolutionarily. -There are currently EVs that charge roughly as quickly as ICE cars refuel. They are very expensive, and that speed of charging degrades the battery much more quickly than lower voltage charging. -People without garages will charge wherever they park their cars, or they will subscribe to car services, or use electric mass transit. -You can already buy a Tesla Model S with 500+ miles of range. In 5 years that range will be found in inexpensive cars. -There are numerous ways to tax EVs, either with mileage taxes or registration or sales taxes. You should be more concerned about the billions in health care costs caused by ICE vehicles that are paid by the government or private individuals. This technology might end up widely adopted, or there might be barriers that consign it to niche use or no use at all. EVs will completely replace ICE vehicles in all but the most niche uses. Quite trying to grasp at reasons they won't and ignoring the myriad problems with ICE vehicles.
