Battery based electric vehicles of today and tomorrow.

because nobody has put up the cost to invent a reprocessing solution.

France reprocesses very successfully and has contracted to build 6 new reactors to replace old designs.

we don't do it because reprocessing creates material you could use to make a bomb. its stupid, and we should be reprocessing and building more plants.

Was watching a documentary on what a farce renewable energy is. Apparently there is another kind of nuclear energy (not based on uranium) that India is using, that is much safer but wasn't chosen in the west because it's not good for making weapons. That freaking figures! Humans! Sorry, the name escapes me.

they use uranium reactors of Russian and French designs. nearly every country claims to be working on thorium reactors, but none have been used commercially.

renewables have their place along with Nuclear and other sources.

Just shoot it into space it will travel trillions of miles away from earth.
Problem solved!

taking mass away from the earth eventually leads to some issues. also, we still strap a flame thrower connected to a bomb to a big tube to get us into space. if it fails with a bunch of nuke waste on top? bad day. maybe someday when we have a space elevator.

Our Mustart 40 amp 220 volt cable for the Nissan Leaf built in battery charger came in Friday. Since the location where I am keeping the charger is not its final home I used this board laying around and lagged the boxes to it to make a move to another location go faster. Now the 6.6 kw charger gets triggers. The 120 volt factory charger takes 20+ hours. I went with 8 gauge wire just because 40 amp is the trend for newer EV's.

At this point I am pleased with the Mustart 40 AMP smart 220 volt cord at connects the grid power to the battery chargers that come inside the Nissan Leaf. I knew it was going to be much faster than 120 volt smart extension cord that runs from grid to charging system built inside the Leaf. I plan to run it to a Zero percent of battery charge today and see how many kWh are needed to bring it it back up to 100%. I read Nissan as the meter to read 100% after the battery is charged to 95% of actual charge. Charges over 80% that set in 90+F temps seem to damage the battery.

What never registered on me was how much feedback it gave. Now I can run front and rear seat heaters plus the steering wheel heater, heat and AC set on 90F and blower on high without losing any range miles. I was at 50% battery charge last night when I finally got the Mustart online and plugged it and the max draw was 26 amps because it was working off of the built in 6.6 kw charger vs the 3.3 kw charger.

In the Leaf the chargers are located top of the normal Nissan engine bay set up under the top cover that is similar to a cam cover. After a couple hours of hard charging last night with the 26 amp draw the cover was getting warm but not hot. The coolant system fans never kicked on that I heard.

Grumpycat I bought my 2016 in part because it is showing the 30 kWh battery rapid degradation issue that you mentioned in your two long posts the other day. Anyone that is trying to understand EV's I recommend you read them for info and to get a handle on Grumpcat's sense of humor.

Now that the Mustart tells the amount of the charge that it puts into the battery I can do some real work testing how much it states it added to the battery and how much the car reports it has used. About a year ago Nissan figured out the computer needed to be updated in some cars. It seems the software was still expecting the 24 kWh that was used in 2016 S models but the 30's were put in the SV and SL in 2016. In 2017 all Leafs got the larger 30 kWh batteries. I have read the 30 kWh rapid degradation only occurs in USA built Leafs and not from Japan or the UK which is interesting.

The issue was found in NZ where Nissan never sold the Leaf or had pulled out of that market for some reason because there were 8000 gray market Leafs with no Leaf service centers. Nissan drilled down to the issue and found the software programming issue. The software is free to all authorized Leaf owners but the gray market owners in NZ have to pay $115 I read. In most cases the battery is not at issue but the computer will stop the charging and discharging too quickly because that is what the computer is telling it to do.

My April build 2016 reports a range of 70 miles when charged to 100% instead of 107 mile range that the manual states. It still will hit 94 MPH when the charge is down to 20% as the manual states it should so I expect the battery is OK to be able to discharge at that rate. Our car has been in service 3 years and 1 month and just hit 22K miles a couple days ago. Now with the Mustart data I can start to better understand how many kwh hours that I am actually putting into it. I want to prove to myself the battery may be fine before I go for the free software update.

How do modern nuclear plants with modern controls and standards stack up?

Very very good, actually. Problem is the USA has mostly early designs which are past their original design life. Westinghouse is building state of the art modular nuclear power plants in China just as fast as they can. We should too.

Why can't we have a reprocessing plant to re-use the "spent" fuel from current plants and reduce it's volume while converting it to something that has a much shorter span while it's dangerous?

The intermediate product too closely resembles bomb material. Jimmy Carter nixed the breeder reactor program for reprocessing spent fuel.

Is my understanding Nissan's 8 or 10 year battery warranty kicks in when capacity falls to 70%.

Our 2016 Leaf with the 30kWh battery is covered for 8 years or 100K miles which ever comes first. On losing the 4th capacity bar you can start a claim I was told at the Nissan dealer where I got ours but first you have to take it in for a software fix that should give you back one or more bars delaying being able to request a new battery.

Looks like Nissan is testing an AWD Leaf. The screen was large.

It seems to me that EV just move the pollution around, they don't actually solve any pollution issues.
