A "Carrington-level" event nowadays would most likely be much less disruptive, as back then all the early radio and spark gap stuff was well under 50 MHz, which is where almost all of the natural noise winds up in the spectrum. Ever notice, for example you can hear your shaver motor on an AM radio but not an FM one. This is not due to AM vs. FM, (well, it is a little) but mostly due to the fact that AM is about 1 MHz and FM is about 100 MHz, well above the "static line" around 50 MHz.

It would take a much stronger signal than back then to cause the same level of disruption. Not saying that can't happen, but modern radio communications are quite a bit more robust than they were back over 100 years ago.

The concern is not so much about the disruption of radio communications, but the power grid. Our society might not survive a massive, long-term (months or even years) blackout (a huge number of transformers might be destroyed all at once by the induced EMF).

You still need very pure water or you poison the process. Where's that water coming from? How do you collect the gaseous hydrogen? You still need to liquify it and all the emrittlement and cryogenic issues are still there.

Even if hydrogen gas is free, it makes no sense as an energy carrier for cars.

They don't collect the gaseous hydrogen in the electrolyzer; they soak it up with a "liquid sponge" ("a recyclable redox mediator (silicotungstic acid) " according to the article's abstract. In principle at least, hydrogen could be stored and transported in this form (a liquid sponge soaked with hydrogen).; the hydrogen can be catalytically released (wrung out of the liquid sponge) when needed. Whether such a system could be built with a practical size, weight, and cost for use in vehicles is another matter.

In order for a Northern European to evolve fair skin and hair, there has to be something that will kill a human of dark skin and hair. Since people with dark skin can survive in Northern Europe, it is not through evolution.

The "something" doesn't have to kill, just reduce the probability of reproductive success. Vitamin D deficiency fills the bill.

+ - China must import more water than the US imports oil->

Submitted by Anonymous Coward
An anonymous reader writes "China does not have the capacity to feed itself. By the estimates of one state official, the country’s agricultural imports require more land to grow than the entire land mass of California.

The reasons are simple. For one, China doesn’t have enough fertile land in production to support its population’s growing food demand.

Theoretically this is fixable. With a bit of time, patience, and technology, barren soil can be rehabilitated In other words, China doesn’t have enough enough productive land capacity to support its population.

But the far greater issue is China’s massive freshwater deficiency. Chief Economist Qian Keming of China’s Agriculture Ministry summed it up by telling the audience at the Third China International Agribusiness Forum:

“Fresh water resources are only 2100 cubic meters per capita, which is only 28% of the world’s average level.”

and

“The shortage of [water for agricultural irrigation] each year is about 30 billion cubic meters. China imported about 148.6 billion cubic meters of water in 2013, which was equivalent to 38% of China’s agricultural water.”

Here’s that number in perspective: China water imports of 148.6 billion cubic meters last year handily exceeded the 569 MILLION (0.569 billion) cubic meters of oil that the United States imported."

BillCable (1464383) writes "

In a major blow to the Washington Redskins, the U.S. Patent and Trademark Office on Wednesday canceled six federal trademarks of the “Washington Redskins” team name because it was found to be “disparaging” to Native Americans.

“We decide, based on the evidence properly before us, that these registrations must be cancelled because they were disparaging to Native Americans at the respective times they were registered,” the PTO’s Trademark Trial and Appeal Board wrote. The panel voted 2-1 in favor of the decision.

Perhaps this move will speed up the inevitable name change which was expected within the next few years."

+ - This Is How Formula 1 Brakes Work

Submitted by cartechboy
cartechboy (2660665) writes "For the most part, you probably have a simple understanding of how your car's brakes work. But a race car, that's a whole different beast. Brembo's the biggest name in the brake industry, and it just released a video explaining the technology that goes into the brakes on a Formula 1 race car from pedal to caliper. Obviously it starts with every component being beefed up from a normal braking system, but there's also aluminum monoblock calipers, carbon rotors and pads, a brake-by-wire system with a redundancy in case of an electronic failure, and a kinetic energy recovery system (KERS). Of course, KERS is the most interesting bit as the it allows for smaller rear calipers than before which of course reduces mass. Believe it or not, all of this stuff ends up trickling down to mass-market cars eventually, it's just a matter of time. So the next time you tap your brakes, remember, that technology was likely proven on a race car at some point."

What I'm wondering is why I want to carry around 2 months worth of fuel in my car and be sitting on top of that amount of potential energy in a crash?

Maybe because of the unlikelihood that all of that energy would be released rapidly enough to cause a safety concern?

Instead of learning a new programming language Makers can draw circuits right away using open source building blocks such as stepper controllers, audio chips, video chips, and even a bitcoin miner. Circuits are loaded to the FPGA and then controlled by the Arduino. It's a very simple arrangement with mind boggling possibilities — everything from bitcoin mining, embedded vision, robotics, to reconfigurable System on Chip designs."
