15 Quotes on Enlightened Business Practices from Steve Jobs’ Guru

Kyle McMillan, GuestAccording to The Business Insider, Steve Jobs only downloaded one book, ever, to his iPad 2: Autobiography of a Yogi, by Paramahansa Yogananda. To those in the know, this should come as no surprise, as it was also his parting gift to all of the attendees at his funeral — the last gesture he made towards everyone closest to him on earth. Jobs’ spirituality was not widely well-known during his life, and while many will contest that certain busi [...]

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.

Tesla to unveil ‘mystery’ life changing product tonight!



Tesla's expected home battery announcement could spark energy revolution. SolarCity has already installed 300 Tesla-made batteries in California homes.


 Excerpt from CBC News 

Tesla CEO Elon Musk is set to make an announcement later tonight. There's been speculation that a large-scale battery announcement is expected, but it's not clear if that will be the case.



The man behind the electric car revolution is expected to unveil a large-scale battery capable of powering an entire house, during an announcement at Tesla Motors headquarters in Hawthorne, Calif.
While the battery will likely slash power bills for consumers, some say it's also a move toward democratizing energy systems.

Elon Musk, CEO of Tesla Motors, teased the announcement on Twitter a month ago, saying a major new Tesla product line will be unveiled at Hawthorne Design Studio at 8 p.m. local time Thursday. "Not a car," he wrote, sparking speculation that it may be a home battery.

Musk, who moved to Canada from South Africa and who briefly studied at Queen's University in Kingston, Ont., before transferring to the University of Pennsylvania, is also chairman of SolarCity, a solar power provider.

SolarCity has already run a pilot program where it installed 300 home batteries made by Tesla in California homes. Another 130 systems were being installed in early 2015, according to the company's website.

The product will be available again in late summer, the company says, as it's working on "the next phase" of the program.

Tesla is also in the midst of building its gigafactory, which has added to the speculation that the company is unveiling a home battery. Musk says that by 2020, the factory will produce more lithium-ion batteries than all the current factories producing them today. 

A home battery attaches to a home's electrical system and collects energy gathered by solar panels when the sun is out, Michael Ramsey, a Wall Street Journal automotive reporter, told CBC's The Current. That energy can then be used when the sun is no longer out.
'This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building.'-— Warren Mabee, of Queen's University
"The idea is that you purchase this system and it allows you effectively to cut the cord," he says of a consumer's ability to forgo energy from the grid. The consumer's electricity bills would be significantly reduced because they would be paying for less electricity from the grid.

This innovation could move the world toward a future where power is generated where we need it and where we use it, says Warren Mabee, director of the Queen's Institute for Energy and Environmental Policy.

"This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building," Mabee says.

In this system, centralized power generation becomes more of a backup than a driver, he says.

Costs remain high

However, the current systems are still very expensive, says Ramsey. The 300 home batteries installed in California cost upward of $20,000, he says.

"It would take years and years and years to cover the utility costs," he says. "It doesn't make sense unless the costs come down."

Ramsey views businesses as having the highest possible economic advantage from this development. The battery could offer businesses a surge of electricity when they have a high demand for power and cut their bills.

Mabee compares the cost of solar panels to cellphones. Smartphones were once very expensive, but each new generation has brought the cost down, he said.

Each year, solar panels become better and cheaper. Solar panels are getting close to their grid parity moment — when the cost of generating solar power is the same or cheaper than buying energy off the grid.

Another grid parity moment may be close, says Mabee. It won't be long before the cost of a solar panel and battery system will match the cost of purchasing electricity from the grid, he estimates.
"That magic grid parity moment is coming faster and faster," he said.

Archaeologists find two lost cities deep in Honduras jungle

Excerpt from theguardian.com


Archaeological team say they have set foot in a place untouched by humans for at least 600 years in a site that may be the ‘lost city of the monkey god’

Archaeologists have discovered two lost cities in the deep jungle of Honduras, emerging from the forest with evidence of a pyramid, plazas and artifacts that include the effigy of a half-human, half-jaguar spirit.
The team of specialists in archaeology and other fields, escorted by three British bushwhacking guides and a detail of Honduran special forces, explored on foot a remote valley of La Mosquitia where an aerial survey had found signs of ruins in 2012.
Chris Fisher, the lead US archaeologist on the team, told the Guardian that the expedition – co-coordinated by the film-makers Bill Benenson and Steve Elkins, Honduras and National Geographic (which first reported the story on its site) – had by all appearances set foot in a place that had gone untouched by humans for at least 600 years.
“Even the animals acted as if they’ve never seen people,” Fisher said. “Spider monkeys are all over place, and they’d follow us around and throw food at us and hoot and holler and do their thing.”
“To be treated not as a predator but as another primate in their space was for me the most amazing thing about this whole trip,” he said.
Fisher and the team arrived by helicopter to “groundtruth” the data revealed by surveying technology called Lidar, which projects a grid of infrared beams powerful enough to break through the dense forest canopy.

That data showed a human-created landscape, Fisher said of sister cities not only with houses, plazas and structures, but also features “much like an English garden, with orchards and house gardens, fields of crops, and roads and paths.”
In the rainforest valley, they said they found stone structural foundations of two cities that mirrored people’s thinking of the Maya region, though these were not Mayan people. The area dates between 1000AD and 1400AD, and while very little is known without excavation of the site and surrounding region, Fisher said it was likely that European diseases had at least in part contributed to the culture’s disappearance.
The expedition also found and documented 52 artifacts that Virgilio Paredes, head of Honduras’s national anthropology and history institute, said indicated a civilisation distinct from the Mayans. Those artifacts included a bowl with an intricate carvings and semi-buried stone sculptures, including several that merged human and animal characteristics.
The cache of artifacts – “very beautiful, very fantastic,” in Fisher’s words – may have been a burial offering, he said, noting the effigies of spirit animals such as vultures and serpents.
Fisher said that while an archaeologist would likely not call these cities evidence of a lost civilisation, he would call it evidence of a culture or society. “Is it lost? Well, we don’t know anything about it,” he said.
The exploratory team did not have a permit to excavate and hopes to do so on a future expedition. “That’s the problem with archaeology is it takes a long time to get things done, another decade if we work intensively there, but then we’ll know a little more,” Fisher said.

“This wasn’t like some crazy colonial expedition of the last century,” he added.
Despite the abundance of monkeys, far too little is known of the site still to tie it to the “lost city of the monkey god” that one such expedition claimed to have discovered. In about 1940, the eccentric journalist Theodore Morde set off into the Honduran jungle in search of the legendary “white city” that Spanish conquistadors had heard tales of in the centuries before.
He broke out of the brush months later with hundreds of artifacts and extravagant stories of how ancient people worshipped their simian deity. According to Douglas Preston, the writer National Geographic sent along with its own expedition: “He refused to divulge the location out of fear, he said, that the site would be looted. He later committed suicide and his site – if it existed at all – was never identified.”
Fisher emphasised that archaeologists know extraordinarily little about the region’s ancient societies relative to the Maya civilisation, and that it would take more research and excavation. He said that although some academics might find it distasteful, expeditions financed through private means – in this case the film-makers Benenson and Elkins – would become increasingly commonplace as funding from universities and grants lessened.
Fisher also suggested that the Lidar infrared technology used to find the site would soon be as commonplace as radiocarbon dating: “People just have to get through this ‘gee-whiz’ phase and start thinking about what we can do with it.”
Paredes and Fisher also said that the pristine, densely-wooded site was dangerously close to land being deforested for beef farms that sell to fast-food chains. Global demand has driven Honduras’s beef industry, Fisher said, something that he found worrying.
“I keep thinking of those monkeys looking at me not having seen people before. To lose all this over a burger, it’s a really hard pill to swallow.”

A Major Victory for the Open Web

Excerpt from blog.mozilla.org
We just accomplished something very important together. Today, the U.S. Federal Communications Commission voted for strong net neutrality protections. This happened because millions of people — including many hundreds of thousands in Mozilla’s community — joined together as citizens of the Web to demand those strong protections.


This is an important victory for the world’s largest public resource, the open Web. Net neutrality is a key aspect of enabling innovation from everywhere, and especially from new players and unexpected places. Net neutrality allows citizens and consumers to access new innovations and judge the merit for themselves. It allows individual citizens to make decisions, without gate-keepers who decide which possibilities can become real. Today’s net neutrality rules help us protect this open and innovative potential of the Internet.

Mozilla builds our products to put this openness and opportunity into the hands of individuals. We are organized as a non-profit so that the assets we create benefit everyone. Our products go hand-in-hand with net neutrality; they need net neutrality to bring the full potential of the Internet to all of us.

Today’s net neutrality rules are an important step in protecting opportunity for all. This victory was not inevitable. It occurred because so many people took action, so many people put their voice into the process. To each of you we say “Thank you.” Thank you for taking the time to understand the issue, for recognizing it’s important, and for taking action. Thank you for helping us build openness and opportunity into the very fabric of the Internet.

Elon Musk drops space plans into Seattle’s lap




Excerpt from seattletimes.com

Elon Musk thought three major trends would drive the future: the Internet, the quest for sustainable energy and space exploration. He’s got skin in all three games.

Of all the newcomers we’ve seen here lately, one of the more interesting is Elon Musk.

The famous entrepreneur isn’t going to live here, at least not yet. But earlier this month he did announce plans to bulk up an engineering center near Seattle for his SpaceX venture. The invitation-only event was held in the shadow of the Space Needle.
If the plan happens, SpaceX would join Planetary Resources and Blue Origin in a budding Puget Sound space hub. With talent from Boeing, the aerospace cluster and University of Washington, this offers fascinating potential for the region’s future.

Elon Musk sounds like the name of a character from a novel that would invariably include the sentence, “he had not yet decided whether to use his powers for good or for evil.”

He is said to have been the inspiration for the character Tony Stark, played by Robert Downey Jr. in the “Iron Man” movies. He’s also been compared to Steve Jobs and even Thomas Edison.

The real Musk seems like a nice-enough chap, at least based on his ubiquitous appearances in TED talks and other venues.

Even the semidishy essay in Marie Claire magazine by his first wife, Justine, is mostly about the challenge to the marriage as Musk became very rich, very young, started running with a celebrity crowd and exhibited the monomaniacal behavior common to the entrepreneurial tribe.

A native of South Africa, Musk emigrated to Canada and finally to the United States, where he received degrees from the University of Pennsylvania’s prestigious Wharton School. He left Stanford’s Ph.D. program in applied physics after two days to start a business.
In 1995, he co-founded Zip2, an early Internet venture for newspapers. Four years later, he co-founded what would become PayPal. With money from eBay’s acquisition of PayPal, he started SpaceX. He also invested in Tesla Motors, the electric-car company, eventually becoming chief executive. Then there’s Solar City, a major provider of solar-power systems.

Musk has said that early on he sensed three major trends would drive the future: the Internet, the quest for sustainable energy and space exploration. He’s got skin in all three games.

At age 43, Musk is seven years younger than Jeff Bezos and more than 15 years younger than Bill Gates.

His achievements haven’t come without controversy. Tesla played off several states against each other for a battery factory. Nevada, desperate to diversify its low-wage economy, won, if you can call it that.

The price tag was $1.4 billion in incentives and whether it ever pays off for the state is a big question. A Fortune magazine investigation showed Musk not merely as a visionary but also a master manipulator with a shaky deal. Musk, no shrinking violet, fired back on his blog.

SpaceX is a combination of the practical and the hyperambitious, some would say dreamy.

On the practical side, the company is one of those chosen by the U.S. government to resupply the International Space Station. Musk also hopes to put 4,000 satellites in low-Earth orbit to provide inexpensive Internet access worldwide.

The satellite venture will be based here, with no financial incentives from the state.

But he also wants to make space travel less expensive, generate “a lot of money” through SpaceX, and eventually establish a Mars colony.

“SpaceX, or some combination of companies and governments, needs to make progress in the direction of making life multiplanetary, of establishing a base on another planet, on Mars — being the only realistic option — and then building that base up until we’re a true multiplanet species,” he said during a TED presentation.

It’s heady stuff. And attractive enough to lead Google and Fidelity Investments to commit $1 billion to SpaceX.

Also, in contrast with the “rent-seeking” and financial plays of so many of the superwealthy, Musk actually wants to create jobs and solve practical problems.

If there’s a cautionary note, it is that market forces alone can’t address many of our most serious challenges. Indeed, in some cases they make them worse.

Worsening income inequality is the work of the hidden hand, unfettered by antitrust regulation, progressive taxation, unions and protections against race-to-the-bottom globalization.

If the hidden costs of spewing more carbon into the atmosphere are not priced in, we have today’s market failure exacerbating climate change. Electric cars won’t fix that as long as the distortions favoring fossil fuels remain.

So a broken, compromised government that’s cutting research dollars and failing to invest in education and forward-leaning infrastructure is a major impediment.

The United States did not reach the moon because of a clever billionaire, but through a national endeavor to serve the public good. I know, that’s “so 20th century.” 

Also, as Northwestern University economist Robert Gordon might argue, visionaries such as Thomas Edison grabbed relatively low-hanging fruit, with electrification creating huge numbers of jobs. 

Merely recovering the lost demand of the Great Recession has proved difficult. Another electrificationlike revolution that lifts all boats seems improbable.

I’m not sure that’s true. But it will take more than Iron Man to rescue the many Americans still suffering.

Future Tech Watch ~ High-tech mirrors to beam heat from buildings into space ~ May replace air conditioning



illustration of reflective panel on building

news.stanford.edu 

By Chris Cesare

A new ultrathin multilayered material can cool buildings without air conditioning by radiating warmth from inside the buildings into space while also reflecting sunlight to reduce incoming heat.

Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation (represented by reddish rays).

Stanford engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space.

A team led by electrical engineering Professor Shanhui Fan and research associate Aaswath Raman reported this energy-saving breakthrough in the journal Nature.

The heart of the invention is an ultrathin, multilayered material that deals with light, both invisible and visible, in a new way.

Invisible light in the form of infrared radiation is one of the ways that all objects and living things throw off heat. When we stand in front of a closed oven without touching it, the heat we feel is infrared light. This invisible, heat-bearing light is what the Stanford invention shunts away from buildings and sends into space.

Of course, sunshine also warms buildings. The new material, in addition dealing with infrared light, is also a stunningly efficient mirror that reflects virtually all of the incoming sunlight that strikes it.

The result is what the Stanford team calls photonic radiative cooling – a one-two punch that offloads infrared heat from within a building while also reflecting the sunlight that would otherwise warm it up. The result is cooler buildings that require less air conditioning.

"This is very novel and an extraordinarily simple idea," said Eli Yablonovitch, a professor of engineering at the University of California, Berkeley, and a pioneer of photonics who directs the Center for Energy Efficient Electronics Science. "As a result of professor Fan's work, we can now [use radiative cooling], not only at night but counter-intuitively in the daytime as well."

The researchers say they designed the material to be cost-effective for large-scale deployment on building rooftops. Though still a young technology, they believe it could one day reduce demand for electricity. As much as 15 percent of the energy used in buildings in the United States is spent powering air conditioning systems.

In practice the researchers think the coating might be sprayed on a more solid material to make it suitable for withstanding the elements.

"This team has shown how to passively cool structures by simply radiating heat into the cold darkness of space," said Nobel Prize-winning physicist Burton Richter, professor emeritus at Stanford and former director of the research facility now called the SLAC National Accelerator Laboratory.

A warming world needs cooling technologies that don't require power, according to Raman, lead author of the Nature paper. 

"Across the developing world, photonic radiative cooling makes off-grid cooling a possibility in rural regions, in addition to meeting skyrocketing demand for air conditioning in urban areas," he said.

Using a window into space

The real breakthrough is how the Stanford material radiates heat away from buildings.

Aaswath Raman are members of the team that invented the breakthrough energy-saving material.
As science students know, heat can be transferred in three ways: conduction, convection and radiation. Conduction transfers heat by touch. That's why you don't touch an oven pan without wearing a mitt. Convection transfers heat by movement of fluids or air. It's the warm rush of air when the oven is opened. Radiation transfers heat in the form of infrared light that emanates outward from objects, sight unseen.
The first part of the coating's one-two punch radiates heat-bearing infrared light directly into space. The ultrathin coating was carefully constructed to send this infrared light away from buildings at the precise frequency that allows it to pass through the atmosphere without warming the air, a key feature given the dangers of global warming.

"Think about it like having a window into space," said Fan.

Aiming the mirror

But transmitting heat into space is not enough on its own.
This multilayered coating also acts as a highly efficient mirror, preventing 97 percent of sunlight from striking the building and heating it up.

"We've created something that's a radiator that also happens to be an excellent mirror," said Raman.

Together, the radiation and reflection make the photonic radiative cooler nearly 9 degrees Fahrenheit cooler than the surrounding air during the day.

From prototype to building panel

Making photonic radiative cooling practical requires solving at least two technical problems.

The first is how to conduct the heat inside the building to this exterior coating. Once it gets there, the coating can direct the heat into space, but engineers must first figure out how to efficiently deliver the building heat to the coating.

The second problem is production. Right now the Stanford team's prototype is the size of a personal pizza. Cooling buildings will require large panels. The researchers say there exist large-area fabrication facilities that can make their panels at the scales needed.

The cosmic fridge

More broadly, the team sees this project as a first step toward using the cold of space as a resource. In the same way that sunlight provides a renewable source of solar energy, the cold universe supplies a nearly unlimited expanse to dump heat.

"Every object that produces heat has to dump that heat into a heat sink," Fan said. "What we've done is to create a way that should allow us to use the coldness of the universe as a heat sink during the day."

In addition to Fan, Raman and Zhu, this paper has two additional co-authors: Marc Abou Anoma, a master's student in mechanical engineering who has graduated; and Eden Rephaeli, a doctoral student in applied physics who has graduated.
