Maybe we can use the corn squeezens for making hand sanatizer.

That is an awesome way to learn the ins and outs of EV's for sure. Your son is creative.

I got the Leaf last fall to get my feet wet since Nissan had a good warranty on the battery that was dying fast after only 3 years. In fact if dropped below 66% of capacity 6 weeks after we got it. Nissan discontinued the 30 kWh battery so they replaced it with the 40 kWa battery so now we have a 2016 car with a 2020 battery with 43 more miles of range.

It looks like many new EV's are being corona virus delayed getting to the market. I expect in countries with high bicycle numbers will be moving over to the EV bikes as time goes forward.

I am glad Tesla is getting back on line. I do want a used Model Y 3-4 years from now.

Yeah- really wanting a model 3, Y, or even an early Model S.

I hope to own one some day.

Your quote about batteries really becomes apparent with the aftermarket Li batteries when building things like the bikes.

There was a pretty steep learning curve and some real let downs on some of the battery packs that we started out with and built,
especially the 1 st couple sets.
I talked him into the 18650's after reading so much about how Tesla chose that as their starting point.

What was not as obvious was just how much over rating of amp hour and re-chargeability was going on on some of the off brand china batteries available on ebay. The 1st set lost about 1/2 of the amp hour availability after just a very few charges, this was using a decent quality LI charger.

I did get a real kick out of riding the bike, at 1 point it was set up to do almost 50 mph.



Here is the other unit he built out of some of the other extra parts, this for mom a mothers day gift.

front wheel drive
about the same amp hour as the bike.

so ugly it's cute?

She likes It.

That is a cool Mother's Day present.

That was an awesome Mother's day gift. How did he get interested in EV bikes?

On EV cars I think the Model Y height would would be better due to my arthritis limited range of motion.

I expect EV's from markers not on the market yet will be delayed a couple years. I saw where an Lincoln EV was out right cancelled. Nissan was in steep decline even before COVID-19 appeared.

I'm thinking Tesla and better of the China EV's will make it OK and VW seems committed to the EV market. Global trade may be slower for the next few years.

That is very good. Due to my fast take offs I average about 3.5 miles per kWh but being careful I can hit 4 in the Leaf.

Running 75 MPH with AC on the other day I was getting more like 2.9 miles per kWh. The new 40 kWa battery (38 kWh in reality with about 30 kWh of for usable range to not drop below 20% of charge) is good for 100-175 miles depending on my foot. I read the Leaf gets max range at 22 MPH with max risk of getting rear ended.

On returning to the house on the last 4 miles I sometimes gain a mile of range due to low speed and being hilly.

This morning I read Nissan is talking about cutting another 20,000 employees world wide to survive their long term decline that has become critical with the 2020 Pandemic now compounding their risk of failure. Nissan really blew their EV lead and seems to be using the same motor in the Leaf for years and just beefing up the power out put of of the three phase inverter.

While Tesla is doing a great job of making EV improvements most shipping are in the $50K - $100K price range. It is going to take an EV in the $20K - $35K range I expect to reach the masses in the USA especially after this 2020 Pandemic gets through with us. Still hoping for a used Model Y in 4-5 years but the Nissan is working out OK. I got it from a Nissan dealership when it came off lease for $13,418.00 which was the buy out price for the person that leased it in 2016 but they were asking over $16K. Within 6 weeks the dying battery triggered the battery replacement warranty and they replaced the 30 kWh battery that had problems with a 2020 40 kWh battery pack at 25K miles. Nissan wants $13K cash to replace that battery so if Nissan is not paying for new EV batteries the cost does not make sense to keep the car on the road.

Battery cost is still the road block to mass EV sales. Other than wiper blades and batteries they need very little upkeep. Nissan does not have water cooled batteries or even air cooled batteries even 10 years later and hot batteries are not cool for longevity. Bolt and Tesla EV's have battery cooling technology.

I did not know Tesla (not Elon Musk but the scientist) actually invented a vehicle that was not powered by fossil fuel or batteries.

This guy is a retired ER doctor with many interests that I have read about and he seems to be serious. He may be of more interest is one has a background in science. He does think our current and on going lock down is going to lead to more secondary deaths than the cause of the lock down itself.
