Electric vehicles during a disaster

[ponytug]

Tesla batteries are flooded in liquid coolant. So if coolant can not get out then flood water can not get in.

The Tesla battery packs are sealed, but they still have pass through for the poles of the battery pack. So, yes, the coolant does circulate in the pack, keeping warm/cool, without shorting anything, but you still have the connector.

Enclosed, yes, but not exactly waterproof. On the bright side, there is a fuse in the Tesla battery pack.

Still, I would be out of there if the water got to six inches...

And you know this how?

Sun Hours Map says you effectively get 3.5 hours/day.

You could get a pretty good estimate rather than simply guess: Solar Cost Estimator

More to consider than just a map. Many homes have a lot of shade from trees, buildings, etc. It my case, I'd have to take out a quarter acre of trees to put in solar panels near enough to the house.

No guessing, Five years ago, I got estimates from three different companies for solar installations. I was told by all three that the only way was to put the panels on my new roof which would have voided the shingle warranty. These systems were designed to offset SOME of my electricity use and would not provide all my needs. This is not taking into consideration the additional load of 3 EV's. These systems would also by law, be inoperative during a power failure and would do me no good during an outage.

BTW, all three companies are now out of business. The guy down the road can't get anyone to service his 5 year old system.

I understand these systems I investigated are not PV and provide no local storage but the problem still remains. The number of panels & batteries needed to supply my needs during a week long outage would change the landscape around the house and put such a system out of my price range.

Don't get me wrong. I'm not saying solar is a bad thing, it just isn't practical for everyone at this time. Hopefully, the technology will improve in the future. If I'm still around then, I might take a second look.

I put my solar in my field, 500+' of trench and 4/0 wire. Definitely increased the cost - ground mount is more expensive than roof mounting plus trenching and cable run - but the panels are optimally oriented, can't mess with my roof, and I've got room to expand (2/0 would've been enough for what I have now, but I spent a couple hundred extra dollars on bigger cable to be able to patch in another 5kW when it's needed).

Thats pretty common when companies bill $35k for a couple of man-days of work to install $15k of components. Eventually customers figure out the racket.

Purely for medicinal purposes.

No…

Where do you get those ingredients during this disaster?

For some reason I always have plenty of those ingredients on hand.

I was listening to the radio today. An interesting topic came up. How would the people in Florida evacuate for hurricane in electric vehicles. it wouldn’t take much for the charging stations to be overwhelmed leaving thousands of motorists stranded as the storm approached.

The second part of the problem would be how do you function without a power grid to charge your electric vehicles. As of now I’ve seen the gas stations bring in generators to run the gas pumps. I don’t think there’s enough generators to recharge all the cars.

I then got to thinking about up north in the winter time and an ice storm/snow storm could also disable the power grid for a long time. One could also add in the problems with tornadoes and floods.

I thought it was an interesting question for all the greenies out there.

Or, the water could get a foot deep and your little green ride shorts out and burns your house down.

I think you're confusing my little green boots for shorts.

I wasn't talking about anyone specific. You or anyone else. If I had a bedroom over my carport, I wouldn't park my battery car in the carport. Bad enough with regular vehicles.

The small generator works well for the service station till the refinery stocks run dry which happens faster than we realize.
Refineries have back up systems for limited operation but their supply sources usually require electricity in their operation.
