Sounds like Musk is a real peach to work for.

Legion, I worked at several greenfield plants as part of the project and then later start up teams. One of them very similar to what was going on at Tesla.
It was 1985 and it was a 300 million dollar plant with all new technology. The goal was "A perfect start up" Nearly a year behind schedule in the end. Some process machines ended up getting the deep six and old technology brought in. It was hell. I remember one conference call when the prez of manufacturing asked us if we were incompetent or just didn't give a damn. Threatened to can us all. Several in the room were relieved of duty that week. Needless to say the atmosphere in the facility was in the dumpster |

Is there an electric car in the world that is profitable? Just wondering. I'm pretty sure the Taycan will be but it ain't here yet. And GM shut down the Volt after losing millions- even with all the subsidies.

Also, we are probably one 60 minutes episode away from E-disaster.. When people see the 4y old kids in congo or wherever mining the earth for their lithium ion batteries, and dying in the process, electric will become the next dirty diesel... Never thought I'd say that but hydrogen might make more sense, if you can stand driving with a grenade under your seats...
My E-car is going back in 60 days, I've enjoyed immensely it as a proof of concept. Probably not getting another until the tech improves however (more battery density, less weight, cheaper). |

If you are going to do Hydrogen, you might as well do Electric/fuel cells. They are less energy efficient than Li-Ion, but you can store the equal of 20 gallons of gas in about 50 lbs! This is equal to the storage of 360 kWh. Fuel cells don't weigh much, so I expect that even with the Compressed Hydrogen tank, Fuel cell, etc., the car will weigh less.
360 kWh would give you a range of 800 miles with a Tesla, and probably lighter. I do expect you will need a small battery (10-20 kWh) for high power. 90kWh battery weighs 1,200 lbs. Replace with a 15kWh battery (weight 200), 100 lbs for the fuel cell, 50 lbs hydrogen. That is 350. I doubt the hydrogen fuel tanks will weigh more than a few hundred pounds for 50 lbs of hydrogen.

Here is a person who installed a Power Wall 2. Cost $32,500 with 5kW of solar. So a 10kW install will cost around $65,000. Also, look at his roof install. Goofy! Not all of the panels are installed the same direction. Finally, 10 months to install.
https://youtu.be/6s6kN9Ezws0 We just did a Mi-Grid install. 10kW, with ground mount array (more expensive than roof) for $44,500. And Mi-Grid includes a 20kW backup generator. Signed contract in mid November and they were online before Christmas. Oh, and in the video, he notes the system will not work in the event of loss of INTERNET access. So, won't work off-grid.

James hits on the most promising hybrid technology thus far, the hydrogen fuel cell. Consume the most prevalent element in our universe, emit water, and very good energy density. Unfortunately hydrogen is difficult, dangerous, and expensive to transport and process. Also, every hydrogen fuel cell vehicle made thus far has cost dramatically more to build than people would ever pay.

Hydrogen power is like Nuclear fusion. A dream that is always “just twenty years away” and not likely anytime soon.
I hope I am wrong about that.

1.1 Percent of German vehicles are fueled by liquefied petroleum gas (LPG).. it cost about 1/3 the petrol price. The emissions are favorable compared to normal gasoline, 15% lower... nothing to really write home about.
