Here’s Why Tesla’s Battery Is A Big Deal


Excerpt from forbes.com

It’s more about where the market and product are going than where they are today. Think about a complementary system of components:

  1. The big grid – always on, highly reliable power which is expensive during peak demand hours, i.e. when a family actually wants to use the power. But usually the electricity is cheap at night when no one wants to use it and those big baseload plants that are hard (or very hard in the case of nuclear) to slow down are still pumping out power. And sometimes that power is provided by strong night winds.
  2. Home solar – Don’t forget that Tesla’s CEO, Musk, is also Chairman of SolarCity which provides zero down leasing. Home solar is often poorly aligned to peak usage, with installers looking for maximum generation with south-facing solar panels rather than maximum generation during peak with south-west facing panels. Then there are the homes with roofs that are poorly aligned to the sun regardless, so imperfect generation is all that is possible. And that peak generation isn’t necessarily perfectly aligned with peak cost of grid electricity either, but merely overlaps with it.
  3. Home storage – Maximum generation alignment of home solar matters less when you can carry forward the unconsumed electricity from solar panels to your evening of cooking, washing dishes, washing clothes, and streaming Netflix on your 40″ tv. And cheap electricity you can store at night and consume when electricity is really expensive is valuable as well.
So these components exist, but to be fair, they existed before Tesla got into the home storage business and have for a long time. And Tesla’s offering costs about twice as much as more typical lead-acid batteries commonly used for the purpose. So why is this particular home storage battery getting so much attention?
  1. Hype – Don’t underestimate the marvel that is Musk’s ability to get attention. The man is a rock star of event unveiling.
  2. Net metering – Right now, there is a lot of conflict between utilities and home solar users and installation companies. Net metering is the requirement that home solar generators get paid for electricity that they produce and pump into the grid, and only pay for the electricity that they draw from the grid. Output vs input is the net. Home solar used to be an advantage to utilities — reduced peak demand — but has become a liability — reduced or even negative revenue from users of the grid. Basically, utilities still have to pay for the grid which home solar generators use, then they lose revenue or outright pay the home solar generator who is getting use of the grid for free. Since utilities pay for the grid out of electricity revenue, they are starting to demand that people with home solar who aren’t paying much for electricity start paying for grid usage to make up for it. This is getting mixed reviews, as you can understand, but in the USA especially is leading to a desire by many to be completely grid free, a dubious value proposition. Tesla’s hype fell into an emerging market opportunity of people who had solar on their roof, didn’t have batteries but are worried that they’ll be forced to pay more.
  3. Time-of-use billing – Combined with smart meters, time-of-use billing is becoming much more common in utilities in the developed world. This model is simple: reduce demand during peak periods by increasing the price, typically combined with incenting shift of demand to off-peak times by lowering the price. Flattening demand curves, especially peaks, is very advantageous for grid managers because they have to have capacity for the peak. This enables storage to time-shift consumption and save at least some money.
  4. Design – Previous storage units are collections of lead acid batteries, basically the same thing you have in your car, but scaled vertically and horizontally. They aren’t pretty, they are heavy, they take up floor space, they require maintenance, and they are pretty much a toxic addition to homes if breached or even if the tops are removed. Tesla’s model is sleek, hangs on a wall and is much more chemically inert with no liquids. It’s a benign home appliance as opposed to an industrial object (much as some people like the industrial aesthetic at home, it’s less common).
  5. The Gigafactory – What Tesla has going for it is that it is building the world’s largest battery factory, and likely expanding it now that the storage line has taken off so brilliantly. Pretty much everyone paying attention knows that Tesla is already producing batteries much more cheaply on a per KWH capacity at greater volume, and the Gigafactory is going to ramp that up. Battery storage has been dropping in price per KWH of capacity for a long time, but it’s closing in on a cusp point where it’s going to be worth it for average consumers to store at least some electricity.
What all of this adds up to is that home battery storage isn’t economical today, but it’s viable for a subset of the high-consuming market, it’s desirable for its green credentials, it’s desirable due to the hype factor and it will defray its costs. And that the home storage market tomorrow will be viable for a much larger percentage of the market with increasing systemic pressures and pricing that will make it more attractive. Tesla’s home storage battery is getting attention because they are staking a major claim to a market which is expected to increase dramatically.

Shortest Total Lunar Eclipse of the Century Visible Early Saturday


 


Excerpt from space.com 
By Calia Cofield 

Don't forget to look skyward in the early hours of Saturday morning (April 4), to catch a glimpse of the shortest total lunar eclipse of the century.

The moon will be completely swallowed by Earth's shadow for just 4 minutes and 43 seconds on Saturday morning, according to NASA officials. During that time, the moon may change from its normal grayish hue to a deep, blood red. The total eclipse begins at 6:16 a.m. EDT (1016 GMT). You can watch a live webcast of the eclipse on the Slooh Observatory website, Slooh.com, or here at Space.com courtesy of Slooh, starting at 6 a.m. EDT (1000 GMT).
That color change can make for a dramatic display, especially for humans in the distant past, NASA officials said. 


"For early humans, [a lunar eclipse] was a time when they were concerned that life might end, because the moon became blood red and the light that the moon provided at night might have been taken away permanently," Mitzi Adams, an astronomer at NASA's Marshall Space Flight Center in Huntsville, Alabama, said during a news conference today (April 3). "But fortunately, [the light] always returned." 

The April 4 eclipse is the third in a series of four total lunar eclipses — known as a lunar tetrad — visible in the United States. Each of the eclipses is separated by about 6 months. The final installment of this four-eclipse series will occur on Sept. 28. Saturday's lunar eclipse follows closely behind the total solar eclipse that took place on March 20.

Earth's shadow has an outer ring, called the penumbra, and an inner core, called the umbra. Where the moon passes into the penumbra, it appears dark, as if a bite had been taken out of it. When the moon passes though the umbra, it turns a deep, red color.

A total lunar eclipse occurs when the moon is totally submerged in the umbra. On Saturday, the moon will begin to enter the umbra at about 6:16 a.m. EDT (1016 GMT) but will not be completely covered by the shadow until about 7:57 EDT (1157 GMT), after the moon has set in most locations east of the Mississippi River.

While the total eclipse will last less than five minutes, the moon will be partially submerged in the umbra for about one hour and 40 minutes. The dark shadow of the penumbra will first be visible on the moon's surface starting at about 5:35 a.m. EDT (0935 GMT), according to Sky and Telescope magazine.

Viewers west of the Mississippi River will be able to see the total lunar eclipse, starting at about 4:57 a.m. PDT (1157 GMT). Skywatchers in Hawaii and western Alaska will be able to watch the entire eclipse, from the moon's entrance to its exit from the penumbra.

Viewing Guide for Total Lunar Eclipse, April 4, 2015
This world maps shows the regions where the April 4 total lunar eclipse will be visible. The best viewing locations are in the Pacific Ocean.

This weekend's eclipse is extremely short because the moon is only passing through the outskirts of the umbra. (The shortest total lunar eclipse in recorded history, according to Adams, was in 1529 and lasted only 1 minute and 41 seconds).

The eclipse will not be visible in Europe or most of Africa. The partial eclipse will be visible in all except the easternmost parts of South America. The best viewing locations for the total eclipse will be in the Pacific region, including eastern Australia, New Zealand and other parts of Oceania.

What Would It Be Like to Live on Mercury?


Mercury With Subtle Colors

Excerpt from  space.com
By Joseph Castro, Space.com Contributor


Have you ever wondered what it might be like to homestead on Mars or walk on the moons of Saturn? So did we. This is the first in Space.com's 12-part series on what it might be like to live on or near planets in our solar system, and beyond. Check back each week for the next space destination.
With its extreme temperature fluctuations, Mercury is not likely a planet that humans would ever want to colonize. But if we had the technology to survive on the planet closest to the sun, what would it be like to live there?

To date, only two spacecraft have visited Mercury. The first, Mariner 10, conducted a series of Mercury flybys in 1974, but the spacecraft only saw the lit half of the planet. NASA's MESSENGER spacecraft, on the other hand, conducted flybys and then entered Mercury's orbit — in March of 2013, images from the spacecraft allowed scientists to completely map the planet for the first time.



MESSENGER photos of Mercury show that the planet has water ice at its poles, which sit in permanent darkness. Mining this ice would be a good way to live off the land, but setting up bases at the poles might not be a good idea, said David Blewett, a participating scientist with the Messenger program.

"The polar regions would give you some respite from the strength of the sun on Mercury," Blewett told Space.com. "But, of course, it's really cold in those permanently shadowed areas where the ice is, and that presents its own challenge."

A better option, he said, would probably be to set up a home base not far from one of the ice caps, perhaps on a crater rim, and have a water mining operation at the pole.

Still, dealing with extreme temperatures on Mercury would likely be unavoidable: Daytime temperatures on the planet can reach 800 degrees Fahrenheit (430 degrees Celsius), while nighttime temperatures can drop down to minus 290 degrees Fahrenheit (minus 180 degrees Celsius).

Scientists once believed Mercury was tidally locked with the sun, meaning that one side of the planet always faces the sun because it takes the same amount of time to rotate around its axis as it does to revolve around the star. But we now know that Mercury's day lasts almost 59 Earth days and its year stretches for about 88 Earth days.

Interestingly, the sun has an odd path through the planet's sky over the course of Mercury's long day, because of the interaction between Mercury's spin rate and its highly elliptical orbit around the sun.

"It [the sun] rises in the east and moves across the sky, and then it pauses and moves backwards just a tad. It then resumes its motion towards the west and sunset," said Blewett, adding that the sun appears 2.5 times larger in Mercury's sky than it does in Earth's sky.

And during the day, Mercury's sky would appear black, not blue, because the planet has virtually no atmosphere to scatter the sun's light. "Here on Earth at sea level, the molecules of air are colliding billions of times per second," Blewett said. "But on Mercury, the atmosphere, or 'exosphere,' is so very rarefied that the atoms essentially never collide with other exosphere atoms." This lack of atmosphere also means that the stars wouldn't twinkle at night.



Without an atmosphere, Mercury doesn't have any weather; so while living on the planet, you wouldn't have to worry about devastating storms. And since the planet has no bodies of liquid water or active volcanoes, you'd be safe from tsunamis and eruptions.

But Mercury isn't devoid of natural disasters. "The surface is exposed to impacts of all sizes," Blewett said. It also may suffer from earthquakes due to compressive forces that are shrinking the planet (unlike Earth, Mercury doesn't have tectonic activity).

Mercury is about two-fifths the size of Earth, with a similar gravity to Mars, or about 38 percent of Earth's gravity. This means that you could jump three times as high on Mercury, and heavy objects would be easier to pick up, Blewett said. However, everything would still have the same mass and inertia, so you could be knocked over if someone threw a heavy object at you, he added.

Finally, you can forget about a smooth Skype call home: It takes at least 5 minutes for signals from Mercury to reach Earth, and vice versa.
