Nestlé is draining public lands dry in California and worldwide. | Story of Stuff | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it

Nestle, known for bullying local communities worldwide, is pumping out millions of gallons from locations in the heart of the state's disaster-level drought. The company then ships the water out of state, or sells Californians back their own tap water for up to 2,000 times its cost. Worse, processing water this way wastes more water than it bottles -- it takes 1.39 liters of water to fill a one-liter bottle, and it takes twice that to make the plastic bottle itself!

Testing shows using microwaves to propel a craft into space might work

Testing shows using microwaves to propel a craft into space might work | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
A team of researchers at Colorado based Escape Dynamics is reporting that initial tests indicate that it might really be possible to launch space-planes into space using microwaves sent from the ground, to allow for a single stage spacecraft. If the idea pans out, the cost savings for sending satellites (or perhaps humans) into orbit could be considerable.


Today's rockets are all based on the same idea, a multi-stage rocket is used, each part filled with propellant that pushes the rocket into space as the propellant is burned. It is a really expensive way to go because the propellant is extremely heavy. ED's idea is to use microwaves beamed from the ground to heat hydrogen carried by the space-plane to push the craft into space, a much more efficient approach. They are reporting that testing done at their facility shows that the idea might be possible.
The testing involved building a thruster that operates on the ground and then testing to see how much thrust is generated—the team is reporting that they achieved a specific impulse of 500 seconds when using helium, and believe that when they switch to hydrogen that number will jump to 600 seconds—enough, they claim, to push a small craft into space.
With a real space plane, the microwaves would strike the heat shield on the bottom of the craft (both at liftoff and as it made its way into space) powering an electromagnetic motor which in turn would heat hydrogen as it was released from a tank—the result would be pushed through a nozzle, resulting in thrust. Once in orbit the plane would stay aloft long enough to deploy a satellite, then glide back down to Earth. The trick here is that the entire system does not have to be efficient, just the craft itself. The microwave array would be powered by electricity, generated by any number of means, down here on Earth.
There are of course still a number of hurdles to pass before the idea can be deemed viable—the microwave array would have to prove strong enough and able to maintain tracking of the craft as it climbed into space, likely the main ones. There might also be safety issues surrounding the firing of such a massive amount of microwaves into space. On the other hand, if the idea proves viable, it could mean sending satellites into orbit for a fraction of the cost of today's systems.

Europe’s real problem: France can’t sell cars

Europe’s real problem: France can’t sell cars | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
It’s not Greece you should worry about.

The way Greece is hogging headlines and tormenting heads of state, you’d think a “Grexit” is the biggest threat to the eurozone’s future. It isn’t. The greatest danger—and it’s being mostly ignored—is the shocking slide in competitiveness of the single currency’s second- and third-largest economies, France and Italy. One ailment encapsulates Europe’s énorme problème: France can’t sell cars.

Put simply, the cost of making products in France is far higher than in the nations it competes with. The hourly labor expense of manufacturing a car or steel beam in France rose 17% over the past decade, more than twice the increase in Germany. And even though wages have merely tracked inflation since 2008, costs keep climbing because workers are getting less and less productive. That’s chiefly because France’s manufacturers are so starved for profits that they can’t afford to replace or refurbish antiquated plants and IT systems.

By contrast, Ireland, Spain, and Portugal have all acted while France fiddled, liberalizing their labor markets and lowering unit costs over the past six years by 7% to 12%. The results have been disastrous for France’s competitiveness. In the past 10 years its share of all EU exports dropped from 12% to 9.5%, the worst performance of any major country in Western Europe.

NASA: This planet is the closest thing to Earth yet - CNET

NASA: This planet is the closest thing to Earth yet - CNET | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
If any of the planet-ending tropes of sci-fi come to pass in real life, we could now have a place to point our not-yet-real starships toward. NASA announced on Thursday that it has found the first near-Earth-size planet orbiting in the habitable zone of a star that is similar to our own sun.

Scientists don't yet know for sure if the planet spotted by the Kepler space telescope, dubbed Kepler-452b, can support life. It's in a region where temperatures are right for liquid water and is only about 60 percent larger than Earth, giving it a decent chance of being rocky like our own planet. NASA scientists also expect that Kepler-452b would have a slightly thicker atmosphere than Earth and probably still have active volcanoes, making it a pretty lively place even if it doesn't have life.

A year on the new planet is just 20 days longer than a year here and while its star is quite a long trek from home for humans at 1,400 light-years away in the constellation Cygnus, its sun is about the same size and temperature as our own. It's about 1.5 billion years older than our sun at 6 billion years, but it has nearly the same temperature and mass.

Ream develops storage cell for solar energy storage, nighttime conversion

Ream develops storage cell for solar energy storage, nighttime conversion | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark. The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source. Those systems are hindered by not being able to use that solar energy at night or when cloudy conditions exist.

The UT Arlington team developed an all-vanadium photo-electrochemical flow cell that allows for efficient and large-scale solar energy storage even at nighttime. The team is now working on a larger prototype.

"This research has a chance to rewrite how we store and use solar power," said Fuqiang Liu, an assistant professor in the Materials Science and Engineering Department who led the research team. "As renewable energy becomes more prevalent, the ability to store solar energy and use it as a renewable alternative provides a sustainable solution to the problem of energy shortage. It also can effectively harness the inexhaustible energy from the sun."

The Morgan Motor Company Ltd. - News

The Morgan Motor Company Ltd. - News | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it

The Morgan Motor Company Ltd. was established in 1909 by H.F.S. Morgan with the design of the Morgan three-wheeler. A four-wheeled model began production in 1936, and Morgan cars have long become famous the world over for their unique blend of charisma, quality materials, craftsmanship and performance.

The ethos at Morgan remains unchanged: all our cars are coach built and subjected to continual development in order to meet current standards of safety and to offer the responsive thoroughbred performance with which our name is associated. The development of our model-range has taken the marque into the 21st Century, and today Morgan builds in excess of 1300 cars per year. The Aero 8, a major achievement for a small Company, was launched in 2000, and continual evolution of the Aero Range has seen the 8 joined by the dramatic Aero SuperSports and its fixed-head sibling, the Aero Coupe. In 2011 we re-launched the Morgan 3 Wheeler, a modern interpretation of H.F.S. Morgan’s classic design. Our ‘Classic’ range continues to be our flagship vehicle – with models including the 4/4, the world’s longest-running production vehicle, and engine sizes ranging from 1600cc to 4800cc, these famous icons are the models perhaps most associated with Morgan.

10 Strategies to Reverse Autoimmune Disease - Dr. Mark Hyman

Autoimmune diseases, when taken all together, become a HUGE health burden. Among these are rheumatoid arthritis, lupus, multiple sclerosis, psoriasis, Celiac disease, and thyroid disease. In fact, over 80 diseases have been classified as autoimmune and the list is growing.

Autoimmune disease now affects over 24 million Americans and five percent of the population in Western countries. They often include weird, hard-to-classify syndromes like inflammation, pain, swelling, and general misery.

What are autoimmune diseases? Well, your immune system is your defense against invaders. Imagine your immune system as an army that must clearly distinguish friend from foe.

Autoimmunity occurs when your immune system gets confused and your own tissue get caught in friendly crossfire.

Put another way, your body is always fighting something, whether it’s battling infections, toxins, allergens, or a response to stress. Sometimes, your immune army redirects its hostile attack against you. Your joints, brain, skin, and sometimes your whole body become casualties.

This whole concept is called molecular mimicry. Conventional medicine accepts this problem, but they stop there and no one LOOKS for what might be creating the problem.  They don’t dig to find out which molecule your cells are MIMICKING.

China is building a massive solar plant in the Gobi desert

China is building a massive solar plant in the Gobi desert | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
Construction has begun on China’s first large-scale commercial solar plant, designed to eventually supply electricity for approximately one million households in Qinghai province. It’s a concentrating solar power (CSP) system, which uses a vast array of mirrors spread across 2,550 hectares (6,300 acres) in the Gobi desert to send thermal energy into a small, focused area.
The plant is being jointly developed by BrightSource Energy, based in Oakland, California, and Shanghai Electric Group. The project’s first phase, involving two 135 megawatt solar towers—enough energy for about half a million homes, according to BrightSource (pdf). There will eventually be six towers.
BrightSource is also a partner in the world’s largest CSP plant, in California’s Mojave desert, which can generate up to 392 megawatts.

Nanowires give 'solar fuel cell' efficiency a tenfold boost

Nanowires give 'solar fuel cell' efficiency a tenfold boost | Discover Sigalon Valley - Where the Tags are the Topics | Scoop.it
A solar cell that produces fuel rather than electricity. Researchers at Eindhoven University of Technology (TU/e) and FOM Foundation today present a very promising prototype of this in the journal Nature Communications.

The material gallium phosphide enables their solar cell to produce the clean fuel hydrogen gas from liquid water. Processing the gallium phosphide in the form of very small nanowires is novel and helps to boost the yield by a factor of ten. And does so using ten thousand times less precious material.

The electricity produced by a solar cell can be used to set off chemical reactions. If this generates a fuel, then one speaks of solar fuels - a hugely promising replacement for polluting fuels.

One of the possibilities is to split liquid water using the electricity that is generated (electrolysis). Among oxygen, this produces hydrogen gas that can be used as a clean fuel in the chemical industry or combusted in fuel cells - in cars for example - to drive engines.

To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution now but it is a very expensive one. Many researchers are therefore targeting their search at a semiconductor material that is able to both convert sunlight into an electrical charge and split the water, all in one; a kind of 'solar fuel cell'.
