That is not end to end encryption. You would need S/MIME, PGP, or other technologies for that, where the message itself is encrypted.
The fact that the transport may be encrypted is pretty much irrelevant since neither the sender nor recipient have full control over the network hops that may be between them. If you send a message to a TLS-enabled host, and it then gets remailed using plaintext, or the recipient downloads it using plaintext, the TLS is not very useful.

Comment Re:Bandwidth? (Score 2) 445

Delta encoding and compression really doesn't help much in many cases.
My iTunes collection in Apple Lossless for example takes over 300GB. Yes, it's all paid for music I ripped from my own CDs.
That would take eons to upload at the current broadband speeds currently available from most carriers.

I am also sure as hell not going to do my video editing, code compiles, etc on a remove drive, either. Even photo editing is painful. It still takes far too long to upload RAW files. I get 50 MB/s from my UHS-1 card to the hard drive with a USB 3.0 card reader. That's 400 Mbit/s. 4 times as much as the peak download speed available from my cable provider. And I don't know how many times the upload speed.

Solar panels generate DC, and it adds a lot to the cost and complexity to convert it to AC. How about co-locating car charging stations at solar power farms, and skipping the DC-AC conversion equipment. It is a win-win.

Unfortunately, the sun doesn't shine 24/7, so this wouldn't be practical. Such a station would only really work around noon on sunny days.
If you don't tie the system to the grid, you would have to store the energy from solar into local batteries. If those were full, any excess energy from the solar farm would be wasted. If the local batteries were empty, then cars could no longer be charged.
The cost of local batteries would be quite expensive, and those would have to be replaced over time.
The only practical way to use a solar farm for charging is to tie it to the electric grid, and that means adding DC to AC inverters. The inverters don't last forever either, but they cost much less than batteries.

That is not true. If I drive the speed limit, which I have been doing the last week, my 2007 Prius actually does get 50 mpg. That is both as measured at the pump and as reported on the computer screen. In the winter, it gets slightly less, closer to 45.

And contrary to Toyota's claims, the Prius gets better higher and more consistent MPG on the freeway than in the city. That was also my experience with the 2001 Prius.

You don't need any costly and failure prone batteries, just connect to the grid and use net metering.
I did a solar install 18 months ago and it came to $6 per watt DC including labor, Enphase micro-inverters, and US made solar panels (Sharp). Total bill was $40k. This was before any state or federal incentives. It was $26k after incentives.
Due to high tiered electricity costs in California and the fact that I live in a large home, that cost will be recouped in 7.5 years.

The total cost to install might be about 20% less now or $8000, but if I had waited I would also have paid more than $4000 electricity costs by now .
