To be clear, I was just pointing out that the energy density of solar panels is too low to make them practical for powering a laptop computer. And of course the cost is prohibitive.

I am of course aware of such systems. We use solar trickle chargers on sailboats all the time. They fill an important niche, and are fine if you're willing and able to charge the battery for relatively long daytime in order to get relatively short runtime.

I was talking indefinite power during the day, with enough reserve to charge the battery for use during the night. For that you need a very big and very expensive RV-type system.

So 60Hz is the freq. of the lithium ion? Got any references for that statement? Sounds like you've been to the Tesla conference.

See his citation. And note:

"DRAFT--DO NOT QUOTE OR CITE"

"The human evidence, as described in the next section, suggests that magnetic fields, rather than electric fields, are associated with cancer incidence..."

"Electric fields were not found to be a critical factor thus far."

This is the old unproven bugaboo of proximity to high-voltage electric transmission lines, not low-voltage residential electric service.

I know, and I honestly wasn'ttrying to offend- my warped sence of humor just found a delicious irony when you pointing out the (very real) shortcomings of an existing technology while waxing poetic about one that is still (mostly?) theoretical!

Point taken.

Yes, I searched after I opened my mouth ( insert foot ). However I still maintain that most of the current operating long distance transmission lines are HVAC. The articles I found listed a handful of HVDC lines, one even originating in my home state of Utah. I learn new things every day. Of course I forget them tomorrow so I can learn it again later, but that's another story.

Kind of like *extended GSM"..huh?

So, you're giving someone a hard time because you googled stuff you don't understand and they didn't bother?

Polly want a cracker?

Nonsense, I use solar power often when out in the field for extended periods. Cost effectiveness isn't an issue when there aren't other viable power sources.

Four hours of good sunlight gives me almost 30 kilowatts of stored power. Its not that expensive. Tad under $5,000.

LOL!

Way less expensive than an RV-type solar system. Way more powerful.

Yeah, but the $450 shipping was ridiculous.

Let me rephrase that...

Kind of like "extended GSM" by US wireless carriers.
