When I used to ride track, one of the promoters said the Intermediate (B) group is where all the carnage happens. About 1 in 14 riders will crash on any given track day. I did a total of 28 track days, and crashed... twice, so he was spot on!

It's good you're feeling the rear wheel begin to slide. I didn't seem to have that skill, or my bike with excessively large Brembos may have interfered, because twice I slid out the rear wheel. One of those times totaled my bike and broke a collar bone. It was fun while it lasted.

A guy at work would take his Tesla to track days. The limiting factor was always the motor or battery overheating. The car would throttle itself down after only a couple of laps. That was 10 years ago though, so maybe the cooling is improved by now.

All articles like that are super fluffy, so the context and spin must be taken into account. Often, a null concept depicted with fancy graphics is super duper ridiculously dreamily fluffy with all sorts of buy-in from allegedly respectable institutions.

It's believable that storage of heat could be done with 98% efficiency, as long as that heat is then used directly in a factory or home, and not used to generate electricity. If it will be used to generate electricity, it must be cheaper and/or smaller than an equivalent battery.

Everyone knows that in a power outage, a refrigerator will be OK for 12 to 24 hours if you keep the door closed. I could see a refrigerator designed with a large thermal mass that only needs to run the compressor for a few hours each day, and the rest of the time only needs a few small fans. But electric companies, despite all their airing of grievances with consumer power production, don't charge less during peak solar.

I would say that no matter what storage technology we get, we must maintain sufficient (full) production capacity (natural gas backup) to carry on in case of extended periods (days, weeks, months) of low production due to weather, natural disaster, war, etc.

BTW, gravity storage (the cranes with bricks fluff) is trivial to debunk. Back-of-the-envelope calculations (mass * gravity * height) easily show that very little energy is stored, even with truly massive bricks and heights. Hydro storage only works because it does the same thing with a BILLION times more weight, and even then, it's incredibly inefficient and only suitable for conserving small amounts in situations where there is massive overproduction.

The roof was absolutely solid and beautiful until the buffoons drilled 28 holes in it and failed to seal them correctly. I can see that it has been leaking and rotting for years. This is a pretty standard problem. There are ways to use purpose-made flashing over the mount points, but they just don't. That takes time and thought. When it stops raining, I'm going to go up and see if I can figure out what they did.

The moment you install solar, your roof warranty is VOID. They don't tell you this. My 50 year warranty is VOID. Often a solar company won't install a system until a new roof is installed -- and then instant VOID. But I think you are right, the warranty might just be for the shingles anyway.

I have to look into my solar paperwork because it was a 25 year warranty, but I'm not sure what that covered -- probably just parts and not labor. The company looks rude and evasive on BBB, does not respond to calls or emails. I have a call into State Farm, who will almost certainly reject it because (1) the first line of the policy says rain damage is not covered, and (2) faulty installations are not covered. I hope they might at least handle it through subrogation to the installer's insurance.

It's likely all of the panels have to be removed, so that all the racks can be removed, so that entire side of the house can be re-roofed. The only roofers who can respond in a timely fashion don't touch solar, so they need to bring in a third party.

I feel pretty silly spending tens of thousands to ruin my roof, which will then cost more to repair than 25 years worth of generation could save.

One thing I do know is, there are good reasons not to get roof solar panels. PG&E and CPUC have sucked a lot of value out of it, generation has been minimal for months, and the ceiling in one of my bedrooms just fell in because the buffoons who installed them drilled holes in my new 50 year warranty roof.

If you were near me (CA Bay Area), I have a spare charger you could try.

So "balancing" has to do with millivolt differences between cells within a battery pack, while "variance" is voltage difference between two battery packs?

If you were experiencing the latter, it seems like Zero raised an error unnecessarily, and in a particularly bad way telling you to go to a dealer. All it had to do was operate normally, give a reasonable charge estimate (72%). At some point it would be plugged in and get "unvarianced".

I've got a 2017 DS 6.5 that is slowly losing its charge.
I don't get to ride much, so it's been garaged most of its life, on/off charger. Exactly 850 miles on the odo.
I noticed on a recent ride that the estimated available miles decreases disproportionately to the actual distance traveled. I've topped it off a few times in the last month, and have discovered that it drops 1/2 or more each day.

Any thoughts on what this means?

(I'd pop down to the dealer for an inspection, however my nearest two dealers shutdown in the last 6 months, so I'm now nearly 200 miles from a dealer. )

That's a huge waste of a magnificent machine that basically has a 10-year life span.

My 2016 FX now drops off very quickly to 50%, sometimes in less than 10 miles. However, if I keep riding, I can still get 50 miles. I think the firmware range estimate calculation is just primitive, non-linear and overly pessimistic as the battery ages. Could this also be the case with yours? Or does it lose half the charge while just sitting there?
