Jim, all of your lectures are great and they're among the top 5 on my chart, but this one is especially helpful because it's something not so commonly taught in such great detail. I wish I could attend your practical classes. Everyday, I watch your videos first and move to others only after completing the time I've allocated for watching yours. Thank you for all the hard work you're putting into these gems. I hope you'll be facilitated to continue and give even more!
Dude! First off, wow! Thank you so freaking much for all the time and effort you put into all of this, you have restored my faith in humanity. Secondly, I love your humour. It actually helps the material stick! You sir are a legend!
You were born to teach. This is such a well-done video - thank you for taking the time to produce this!! Great information, well-staged, clear, and funny. Damn!
Very good lectures. In batteries generally the total energy is more if measured say over a 10 hr draw vs 1hr at 10xs amp, so amp/hrs is usually expressed over an 8 hr period to get higher Ah, but you get less total energy when discharge is done faster at higher amps.
I am not well versed in this topic. But since I last studied (1996 was a long time ago), batteries were still in an infant stage where they would deteriorate over time with charge and discharge cycles. Is it still the same or has it gotten better? My current understanding of the most popular batteries (lithium-ions) is that lithium mining is highly detrimental to the environment. Is there any other material that we can use to store the charge in a battery other than lithium (at a large scale)?
Wow 😳. I had no idea that the bullet had so much less power than the battery. But what really made me think about it was the fact that you stressed ==> ENERGY OVER TIME
Yes, I spent this year updating a bunch of lectures in the the Basic Electricity and Electronics 1 series. Almost done! Once I wrap this up expect a bunch more new stuff coming your way.
True dat. Ever heard of a thorium reactor? I attended a presentation on future nuclear power a couple years ago and one of the key points was the abundance of thorium, the reduced amount of nuclear waste, and the reduced risk of weaponization. Interesting concept.
@@bigbadtech Yeah, I wonder if anyone's done the math on whether the production, installation and maintenance of solar panels or wind turbines can be done strictly with solar/wind. All the way from mining the raw materials, transporting and refining, transporting again to the factories, running said factories to delivery/installation and maintenance. Naturally, there is no mining equipment that run on batteries so you'd have to sell electricity to offset the fuels used. Speaking of batteries, same thing. At least cobalt mining has a low carbon footprint. The factory I work at has a $50k/mth electric bill. They make plastic film/bags. It's a small plastic film/bag operation relatively speaking.

thank you for the lessons.
i think rural areas can achieve this renewable energy leap but big cities have no room for that.

True dat. Check out the battery discharge characteristics lecture at: ua-cam.com/video/sM2ss-EvAco/v-deo.html

32:41 Beepbopping down the street won't know the difference between power and energy LOL.

The video before this was in 2014 and now it went all the way into 2020. urhm ok. Like how its laid out on the playlist.

Hah, I put my water heater on a timer to deliver for one shower or load of laundry. Figure I save 10 kWh/day, until I reinstall my solar thermal.
Then throw in nuclear power and the debate with renewables really heats up :)

@@bigbadtech interesting thank you for everything
