If they get to the theoretical capacity, it is true that they will someday be similar. Propulsive efficiency of jet engines is already very good, there is not much room for electric to improve on this - but they could conceivably be similar.

On the other hand, as the jet fuel is consumed the weight decreases. Batteries stay the same weight for the entire flight.

No question. The issue is that - under the current Verizon scheme at issue - only Verizon can pursue this business model. Anti-net-neutrality proponents would argue that Netflix should be able to pay Verizon more money for access, and Verizon could then use that money to upgrade. Net neutrality proponents would argue that Verizon should just directly charge their customers to use more bandwidth, and then use that money to upgrade.

Verizon wants a little of both to give themselves something of a monopoly (1). That doesn't benefit anyone except Verizon.

(1) Not really a monopoly, as cell phone service is fairly competitive. Verizon does have the best rural network, though, and they have something of a monopoly outside of metro areas.

Submission + - GOP loses privacy and tech credentials with departure of Rand Paul (usnews.com)

SonicSpike writes: The Republican presidential campaign lost its biggest privacy advocate on Wednesday when Sen. Rand Paul of Kentucky dropped out of the race, leaving doubt about whether the remaining candidates can resonate with the tech community or voters concerned about government surveillance.

Taking a libertarian stance on Internet issues including encryption and the National Security Agency's snooping has been a key part of Paul’s campaign effort to attract tech savvy younger voters, while other Republican candidates make hawkish statements in favor of mass surveillance. Tech policy generates less excitement from voters in presidential elections than issues like national security or the economy, however, which in part explains how Paul struggled below 10 percent in most election polls this past year.

Paul began his outreach to the tech industry even before launching his campaign with appearances including visiting the South by Southwest Interactive Conference. During an exclusive interview with U.S. News at the conference he became the first potential candidate to support the right for Google and Apple to sell encrypted smartphones, countering criticism from the FBI that the privacy software would damage law enforcement investigations.

“There is a right to privacy and the government needs to stay out,” Paul told U.S. News, expressing a stance that became a hallmark of his campaign. “If they want to look at your information, if they want to collect any of your data, they should do it with a judge’s warrant with probable cause if they think you have committed a crime.”

Silicon Valley donors cast a wide net supporting both parties during presidential elections, but Paul’s stance in favor of encryption and limits on government surveillance reflected the positions of numerous companies like Facebook, Apple and Google, and promised to attract funding if his campaign gained traction.

This works well for some people (hell, I have a basement server). But I want off-premises backup. Services like Crashplan, Dropbox, etc. are perfect for this. Sure, you could find a technically-inclined friend - but sometimes things aren't worth the hassle and unpredictable bandwidth usage.

LOL, now you are stretching.

No, I'm still using a tank of brine solution - but it only needs to contain a kilogram of actual solids. That's a small tank compared to the 1700kg worth of water that you would otherwise be carrying.

But I'm happy to concede that you could solve this with other means besides a brine tank. Either way, it's a very solvable problem and would not hold up such a project.

And just to give you some numbers to play with... MAXIMUM recommended dissolved solids in drinking water is 500mg/L. An Airbus A380 carries 1700 L onboard. Thus the weight of the water is 1700kg and if all of that water was grossly overtreated to the maximum limit, you would need to carry 0.85kg in solids with you.
