Now the tethering thing would have value for me, if it would allow me to shut off the expensive DSL service to my home. Is that realistic? Who's your provider, and what kind of speed/reliability do you get?
If you're like me, it's the expense of your talk, text and data plan that you dislike, not the features of a smartphone.
I pay $20 every 90 days to Virgin Mobile (works out to $6.67 per month). I'll upgrade to a smart phone if and when the price of a plan that includes a reasonable amount of data drops to $15 per month. Until then, I'll make a mental note of what online content I'd like to consume, and wait until I get home to consume it.
Calculate the annual cost of your cell phone plan; do you find that having instant gratification of your online desires is worth that cost? Not judging; just curious.
TFA says CO2 levels are at an all-time high. That means the predicted disasters were not averted because anybody did anything to reduce CO2 emissions. The predicted disasters were averted because the predictions were wrong. Predictions such as...
* "entire nations could be wiped off the face of the earth by rising sea levels if global warming is not reversed by the year 2000.” -- U.N. official Noel Brown, in 1989
* We have only “50 days to save the world from global warming” -- UK Prime Minister Gordon Brown, in 2009
we have no guarantee we can survive in any climate other than the one we evolved in
Except historical precedent. Even low-tech humans have adapted to a huge range of climates. Think Inuit living on the edge of Baffin Bay, and Bedouins living in the deserts of Sudan.
Technology can't provide us with food when none of our crops can grow anymore.
Think veggies growing in greenhouses that are either cooled or heated -- depending on which way climate change goes -- by nuclear power plants. Is that not an example of technology providing us with food?
(Nevermind that global warming will cause the amount of arable land to increase. There are huge tracts of land in Canada, Siberia and Alaska that will be farmed if the growing season gets a little longer.)
I'm not saying mucking with the climate is a good idea. But your dire predictions of possible human extinction are right out; they're the kind of alarmism that destroys credibility.
But is it strong enough to build a space elevator? That is the killer app for high-tensile-strength materials.
Of course, then we had the prospects of global thermonuclear war hanging over our heads as well, so the idea of the world having to rebuild everything didn't seem far-fetched at all.
I wasn't aware that threat had gone away. As of 2013, Russia had 8,500 warheads and the U.S. had 7,700. China and North Korea both have more now than they did in the 1970s.
even when they're nearly bumper-to-bumper
Driver's Ed teachers always told their human students to maintain a two-second following distance. With the much faster reaction times of autonomous vehicles, a safe following distance can be redefined to a much shorter value.
This is going to tremendously increase the carrying capacity of the existing highway system.
Hydrogen is a safe lifting gas for airships. “Odorless, Colorless, Blameless” by NASA employee Richard Van Treuren (Air and Space/Smithsonian magazine, April/May 1997) provides a great explanation. Here's a summary: http://www.green-energy-news.c...
Solar energy has always "worked." But it has not always been cost-effective.
Slashdot readers who held nuanced views that mass adoption should wait until it was cost-effective, have been characterized by other, un-nuanced Slashdot readers as "angry."
And it's not "hippies" who were right about solar; credit goes to the semiconductor scientists who kept upping the efficiency of PV cell designs, while reducing manufacturing costs.
If the customer (the U.S. government) wants its auditors to be able to question individual employees, that should be clearly stipulated in the contract, and then the contractor should have no qualms about meeting the terms of that stipulation.
Lesson learned for how to draw up future contracts, I guess.
