Thanks for your efforts. I spite of how irritating Remy can be, he does offer a lot of good advice. Now I have to read up on Gregski's evaporator idea! I'm still surprised by one factor on this, and other similar forums...very little discussion about various legal and financial ramifications of building and operating these vehicle creations in public. I used to participate on other forums, like DIY solar power, until I was completely flamed for bringing to peoples attention the FACTS about some of the 2020 NEC requirements, and what that might mean for people trying to install DIY batteries in their homes. I got fed up reading comments from people who would reply "f..k the insurance companies, I'll do what-ever I want". So, I just quit participating.
Insurance companies are scrambling to cut their losses in every way possible. Keeping that in mind, it would make a lot of sense to protect your investment, your project, your neighbors, and yourself by paying attention to things that many of us would never think of. The internet is a wonderful tool for learning, the problem being separating fact from fiction. Based on some scathing, withering comments Remy posted at various times, I choose to ignore "why" he does that, and look for things I can learn from his posts. As a result, I've elected to take time, and get some real world experience with an EV by searching for an inexpensive gen 1 Leaf I can actually drive. I already bought a 2011 Leaf with 27 miles on it, wrecked. So, lots of parts to keep a car on the road while I figure out how some of these systems work.
Hobbies are great, and for a lot of people, it might not matter if they ever get an EV conversion on the road. There is an old school hot rodder in my neighborhood that just loves to have people stop by his shop and shoot the breeze. For him, the fun part is going to swap meets, making something unique, helping others, etc. But his cars are not likely to burst into flames going up a hill, or leave him stranded in the middle of nowhere. He is also not likely to be sued by someone who took his advice, and then built something that is dangerous, and he won't die because he didn't use safety precautions while dealing with high voltage. Your mileage may vary.
