It’s more about where the market and product are going than where they are today. Think about a complementary system of components:
- 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.
- 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.
- 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.
- Hype – Don’t underestimate the marvel that is Musk’s ability to get attention. The man is a rock star of event unveiling.
- 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.
- 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.
- 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).
- 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.

The Hubble Space Telescope this week celebrates 25 years in Earth's orbit. In that time the telescope has studied distant galaxies, star nurseries, planets in our solar system and planets orbiting other stars.
But, even with all that, you could argue that the astronomer for whom the telescope is named made even more important discoveries — with far less sophisticated equipment.

In the 1920s, Edwin Hubble was working with the 100-inch Hooker telescope on Mount Wilson, just outside Los Angeles. At the time, it was the largest telescope in the world.
On a chilly evening, I climb up to the dome of that telescope with operator Nik Arkimovich and ask him to show me where Hubble would sit when he was using the telescope. Arkimovich points to a platform near the top of the telescope frame.
"He's got an eyepiece with crosshairs on it," Arkimovich explains. The telescope has gears and motors that let it track a star as it moves across the sky. "He's got a paddle that allows him to make minor adjustments. And his job is to keep the star in the crosshairs for maybe eight hours."
"It's certainly much, much easier today," says John Mulchaey, acting director of the observatories at Carnegie Institution of Science. "Now we sit in control rooms. The telescopes operate brilliantly on their own, so we don't have to worry about tracking and things like this."
The headquarters of the Carnegie observatories is at the foot of Mount Wilson, in the city of Pasadena. It's where Hubble worked during the day.
A century's worth of plates are stored here in the basement. Mulchaey opens a large steel door and ushers me into a room filled with dozens of file cabinets.
"Why don't we go take a look at Hubble's famous Andromeda plates," Mulchaey suggests.
The plates are famous for a reason: They completely changed our view of the universe. Mulchaey points to a plate mounted on a light stand.
"This is a rare treat for you," he says. "This plate doesn't see the light of day very often."
This glass side of a photographic plate shows where Hubble marked novas. The red VAR! in the upper right corner marks his discovery of the first Cepheid variable star — a star that told him the Andromeda galaxy isn't part of our Milky Way.

The plate shows the spiral shape of the Andromeda galaxy. Hubble was looking for exploding stars called novas in Andromeda. Hubble marked these on the plate with the letter "N."
"The really interesting thing here," Mulchaey says, "is there's one with the N crossed out in red — and he's changed the N to VAR with an exclamation point."
Hubble had realized that what he was seeing wasn't a nova. VAR stands for a type of star known as a Cepheid variable. It's a kind of star that allows you to make an accurate determination of how far away something is. This Cepheid variable showed that the Andromeda galaxy isn't a part of our galaxy.
At the time, most people thought the Milky Way was it — the only galaxy in existence.
"And what this really shows is that the universe is much, much bigger than anybody realizes," Mulchaey says.
It was another blow to our human conceit that we are the center of the universe.
Hubble went on to use the Mount Wilson telescope to show the universe was expanding, a discovery so astonishing that Hubble had a hard time believing it himself.
If Hubble could make such important discoveries with century-old equipment, it makes you wonder what he might have turned up if he'd had a chance to use the space telescope that bears his name.

Just look up! Monday night, you’ll be able to see a beautiful sight. Jupiter and the moon will be the brightest objects in the sky. And, with some basic binoculars, you’ll be able to see even more.
The largest planet in our solar system, Jupiter, will be pairing up with the moon Monday night. The moon makes a pass by Jupiter, and every planet, at some point each month during its orbit. Monday night, the moon will appear fairly large, called a waxing gibbous moon, and that only happens every few years, according to Jim Lattis, Director of UW Space Place at the University of Wisconsin-Madison.
“But the interest need not be in whether it’s unusual. Rather, it’s a beautiful sight and leads people to look up and think about astronomical things and our place among them,” Lattis said.
After Venus sets, Jupiter and the moon will be the two brightest objects in the sky. Jupiter and the moon will reach the high point in our skies in late evening. With binoculars or a telescope, you’ll even be able to see some of Jupiter’s Galilean moons. They’ll look like little points of light.

Excerpt from washingtonpost.com
By Blaine Friedlander Jr.
In winter’s waning weeks, Venus and Jupiter continue to accentuate the night heavens, we change our clocks forward and we grab spring with no intention of letting go.
Check the west-southwestern heavens at dusk to spy the vivacious Venus and the dim Mars. In late February, the two planets met for a sweet cosmic waltz, but in March, they appear to separate. Venus approaches negative fourth magnitude (very bright) while Mars makes do at magnitude 1.3 (dim, hard to find in urban light pollution). With a clear sky, Mars looks like a red pinpoint.
A young, waxing crescent moon visits Mars on the evening of March 21, and on the next evening the crescent flirts with Venus.
Robust Jupiter ascends the evening’s eastern sky. Find this gas giant at a -2.5 magnitude, very bright, in the constellation Cancer. The lion in the constellation Leo appears to stare at the planet. By the Ides of March, find it south around 10:30 p.m.
The waxing gibbous moon drops by the dazzling Jupiter on March 2, days before the moon itself becomes full on March 5.
Catch the ringed Saturn rising after midnight in the east-southeast now, hanging out near a gang of constellations, Scorpius, Ophiuchus and Libra. It’s a zero magnitude object, bright enough that it can be seen under urban skies. The waning moon loiters near Saturn before dawn on March 12. On that morning, the reddish star below them is Antares.
We adjust our clocks to Daylight Saving Time at 2 a.m. March 8. Spring forward, moving the clock ahead one hour.
Winter is almost over. Spring is weeks away. The vernal equinox brings spring’s official arrival on March 20 at 6:45 p.m.
Also on March 20 — the day a new moon — the North Atlantic and the Arctic waters get a short total eclipse. We won’t see it here, but Slooh.com will carry it live. Totality will start seconds after 5:44 a.m. and end at 5:47 a.m., according to Geoff Chester of the U.S. Naval Observatory.

| Armed with one of the largest telescopes in the world, the aptly named Very Large Telescope at the ESO Observatory in Chile, astronomers are conducting a search for what they once were certain had to be a brown dwarf star. The only problem is that now the star seems to have vanished without evidence. What happened? Brown dwarfs, compared to their better known red dwarf counterparts are significantly cooler, dimmer objects which at a glance bear more resemblance to planets than to other stars. Although they release heat and bear a chemical composition similar to that of the sun, astronomers tend to refer to them as “failed stars,” since they are too small to set off any thermonuclear reactions within their cores. This particular vanishing dwarf was thought to be part of a double-star system, the V471 Tauri, located within the Taurus constellation, only 163 light years from Earth. Within this system, the stars orbit each other in 12 hour intervals, which causes the brightness to diminish every six hours, when one star crosses directly in front of the other. |
However, the timing of this eclipse never happened at an entirely predictable pace, leading the researchers to suspect that a brown dwarf’s gravitational pull was pushing on the stars and causing the lapse – it’s the only thing consistent with the minimal lapsing patterns. With the use of a new powerful camera called SPHERE, they set out to plot out the location of the brown dwarf, but found nothing where they predicted it would be. “This is how science works,” said Adam Hardy, the study’s lead author who remains undaunted by the road ahead. The new study was published this week by the journal, Astrophysical Journal Letters. “Observations with new technology can either confirm or, as in this case, disprove earlier ideas.” Perhaps most intriguing is that while a brown dwarf appears to be hiding from them, the cluster it waxes influence over is among the brightest and largest of deep-sky objects visible in the evening sky. The binary star system is found in what astronomers call the Hyades cluster, named for the nymphs of Greek mythology who are responsible for the rain. |

Excerpt from ufoevidence.org
On the evening of 23 November 1953, an Air Force radar controller became alerted to an "unidentified target" over Lake Superior, and an F-89C Scorpion jet was scrambled from Kinross AFB. Radar controllers watched as the F-89 closed in on the UFO, and then sat stunned in amazement as the two blips merged on the screen, and the UFO left. The F-89 and it’s two man crew, pilot Felix Moncla and radar operator Robert Wilson, were never found, even after a thorough search of the area.
Press article, regarding the incident, in the Wisconsin State Journal (Madison, WI), Nov. 25, 1953.
1st Lt. Felix E. "Gene" Moncla, Jr., pilot of the F89C Scorpion jet. Moncla was accompanied by radar operator Robert Wilson in the rear seat.
The channel that connects Lake Superior with the other Great Lakes flows through the Soo Locks near Saulte Ste. Marie, Michigan. On one side of the channel is the U.S., and on the other side is Canada. The fact that this area is on a U.S. national border makes it a restricted airspace. As such, it was monitored by the Air Defense Command in 1953.
On the evening of 23 November 1953, an Air Defense Command Ground Intercept radar controller at Truax AFB became alerted to an "unidentified target" over Soo Locks. He sounded the alert, and an F-89C Scorpion jet was scrambled from nearby Kinross Field. The jet was piloted by 1st Lieutenant Felix Moncla, Jr., with 2nd Lieutenant Robert Wilson in the rear seat as radar operator.
Ground Control vectored the jet toward the target, noting that the target changed course as the F-89 approached it at over 500 mph. Lt. Wilson had problems tracking the target on his onboard radar, so ground control continued to direct the jet to the target. For thirty minutes, the jet pursued the radar blip and began to close the gap as the UFO accelerated out over Lake Superior.
As Ground Control watched, the gap between the two blips on the radar screen grew smaller and smaller until the two blips became one blip. Ground Control thought that Moncla had flown over the target and that the two blips would separate again as he moved past it.
That didn't happen. Suddenly, the single blip flashed off the screen and the radar screen was clear of any return at all.
Frantically, Ground Control tried to contact the F-89 by radio. There was no response. Marking the last radar position, Ground Control dispatched an emergency message to Search and Rescue. That last sighting was about seventy miles off Keweenaw Point in upper Michigan, at an altitude of 8,000 feet, approximately 160 miles northwest of Soo Locks.
After an all night air/sea rescue search, not a trace of the plane or the men was ever found. No debris, no oil slick, nothing was ever found.
Officials at Norton Air Force Base Flying Safety Division issued a statement that "the pilot probably suffered from vertigo and crashed into the lake." However, this was merely speculation and was based on hearsay reports that Moncla was prone to vertigo.
The Air Force explained the unknown radar target at first as a Canadian DC-3, then later as a RCAF jet. Canadian officials responded that there were no Canadian aircraft in the airspace over the lake at any time during the chase. The Air Force finally stated that the F-89 had exploded at high altitude, ignoring the fact that this would have left a lot of debris on the lake surface.
NICAP investigators found that mentions of Moncla's mission - chasing an unidentified target - had been obliterated from official records. Project Bluebook files simply listed the case as an "accident."
Off the record, those that were present in the Ground Control radar room that day have expressed other opinions. They think that whatever the F-89 was chasing directly caused the disappearance of the jet...

The moon pairs with the brightest star in the constellation Virgo on Tuesday. Illustration by A.Fazekas, SkySafari |
Excerpt from news.nationalgeographic.com
An eclipse of a volcanic moon by the king of planets, Jupiter, will thrill stargazers this week, as Earth's moon rides above the ringed world, Saturn.
Moon meets Maiden. On Tuesday, January 13, early birds will enjoy a particularly close encounter with the last quarter moon of the month and with the bright star Spica. All the action takes place in the constellation Virgo, the Maiden, halfway up the southern sky at dawn.
The 250-light-year-distant star appears only 2 degrees below the moon, a distance equal to about the width of your thumb held at arm's length.
It's amazing to realize that the light from Spica left on its journey to Earth back in 1765. That's the year that Great Britain passed the Stamp Act, the first direct tax levied on the American colonies and a prelude of the parliamentary oversteps that led to the American Revolution.
Mercury at its best. Look for faint Mercury about a half-hour after sunset on Wednesday, January 14, just above the southwestern horizon.
The innermost planet will appear at its farthest point away from the sun, a moment called the greatest elongation. Sitting 19 degrees east of the sun, it would be challenging to track down its faint point of light if it weren't for the nearby, superbright Venus.
The planetary duo will appear only 1.3 degrees apart, making the pair particularly impressive when viewed through binoculars or a small telescope. Look carefully and you may notice that Mercury appears to be a miniature version of the half-lit moon...
This skychart shows Venus and Mercury in close conjunction in the southwest sky after sunset on Wednesday.

Volcanic moon eclipse. Sky-watchers armed with telescopes will witness a distant eclipse of Jupiter's moon Io in the early morning hours of Friday, January 16.
At 12:27 a.m. EST, the gas giant's own shadow will glide across the tiny disk of the volcanic moon, which will be visible to the west of the planet.
Also early on Thursday night at 10:56 p.m. EST, Jupiter's massive storm, the Great Red Spot, crosses the middle of the planet's disk. Appearing as an orange-pink oval structure, this hurricane circles the planet every 12 hours or so and is three times larger than the Earth.
This wide-angle skychart shows the location of Jupiter in the southeast sky on Thursday evening and early morning Friday. The insert telescope view shows Jupiter and location of its moon Io just before it enters the planet’s shadow.

Luna and Saturn. Later on, near dawn on Friday, January 16, the waning crescent moon will appear to park itself just 2 degrees north of Lord of the Rings.
The ringed world can't be missed with the naked eye since it is the brightest object visible in the southeastern predawn sky. Its proximity to the moon will make it that much easier to identify.
Train a telescope on this yellow-tinged point of light, and it will readily reveal its stunning rings, tilted a full 25 degrees toward Earth. Currently Saturn sits nearly 994,000 miles (1.6 billion kilometers) away from Earth, which means that the reflected sunlight off its cloud tops takes 87.4 minutes to reach our eyes.Happy hunting!
