Can't use lithium ion as a replacement for AAs. Lots of things still run on AAs. Flashlights, game controllers, kid's toys, remote controls, some of the "fairy lights" that are so popular for decorating these days (strings of LED lights). I've got a beard trimmer that runs on a single AA battery, I use rechargeable for that.
Admittedly, I've been out of the rechargable AA market for 15 years or so, but I could have sworn I had...
The chart seems to bear that out. It has somewhere from 33% to 100% more Wh/kg than NiMh.
You know, I looked for it on the chart, but didn’t see it...probably because it was the FIRST THING ON THE LIST.
I was debating about saying how NiCad still has a ton of industrial uses, and that it stuck around as the choice for RC planes well after NiMh became popular because of its ability to take punishing charge/discharge cycles. (I'm assuming that the weight savings of LiPo has finally won out, but I don't know for certain.)NiCD is very much alive and well. It's cheap, and it lasts forever, as long as it's maintained. Each chemistry has its advantages, but while NiCd has largely exited the consumer market, it'll be around for a long, long time.
Isn't lower toxicity also on the list? I know NiCad has been banned from consumer product use in some countries, but I'm not sure how lithium chemistries compare to NiMh.
If they reach a landfill, flammability is no longer a concern.
Now that I'm not on tablet:
How will they sign up???Do you need help figuring out basic 30 year old, outdated technology? If so, one of my local libraries has just the course for you!
A mouse is the weapon of a desktop user. Not as clumsy or random as a trackpad. An elegant tool, for a more civilized age.
Tapping? Whatever the heck the official term is for using touch-screen technology. Smart phones, tablets, even some laptops have touch screens (though I hope fewer and fewer of those will be made, stupid Windows). Most of the people around here who "don't use computers," are retirees who skipped the entire generation of desktop home computer tech and went straight to iPhones. Though, to be fair, after living around here and listening to some of the older members of the population talk about their phones, the ad with the three old ladies where one plays Candy Crush by smashing candies with a hammer may not be such a caricature after all.
At present, tablets and phones are not a replacement for desktops/laptops. For entertainment, they're pretty capable; for accessing essential websites, especially government forms and applications, banking, insurance, etc. they're still kinda hit-or-miss. Chances are a class like this is meant to help with that type of computer literacy more than entertainment. While I would agree that a class like that should be offered for touchscreen computing, mouse/trackpad has yet to be made obsolete.
It seems my enthusiasm was premature. The chromecast support on VLC 3.0 isn't working for me, or a lot of other people, either. Doh.
