Tesla’s $3,000 Powerwall Will Let Households Run Entirely On Solar Energy

You almost certainly associate Tesla with cars — very cool cars — but the company has an even grander vision beyond that. Today, CEO and founder Elon Musk unveiled ‘Tesla Energy’ — a new business arm that is focused on ending our dependence on grid power and switching instead to solar energy.

The first Tesla Energy product is ‘Powerwall Home Battery,’ a stationary battery that can power a household without requiring the grid. The battery is rechargeable lithium-ion — it uses Tesla’s existing battery tech — and can be fixed to a wall, removing much of the existing complexity around using a local power source.

“The issue with existing batteries is that they suck,” Musk said in a press conference announcing Tesla Energy. “They are expensive, unreliable and bad in every way.”

Tesla’s solution, he said, is different.

For one thing, the company’s batteries cost $3,500 for 10kWh and $3,000 for 7kWh — add your snarky Apple Watch price comparison here. They are open for pre-orders in the U.S. now; the first orders will be dispatched “in late summer.”

Like regular batteries, they can be used together — up to nine can be stacked up together to create a strong and reliable power source. Musk said he believes they can help people in emerging markets or remote locations ‘leapfrog’ the need for existing power systems, in a similar way that mobile phones have become more important than landlines in remote parts of the world.

How To Hide Text In Microsoft Word 2007, Reveal It & Protect It

Sometimes what we hide is more important than what we reveal. Especially, documents with sensitive information, some things are supposed to be ‘for some eyes only’. Such scenarios are quite common, even for the more un-secretive among us. You want to show someone a letter composed in MS Word, but want to keep some of the content private; or it’s an official letter with some part of it having critical data. As important as these two are, the most common use could involve a normal printing job. Many a time we have to print different versions of a document, one copy for one set of eyes and others for other sets. Rather than creating multiple copies and therefore multiple printing jobs, what if we could just do it from the same document? That too, without the hassle of repeated cut and paste. We can, with a simple feature in MS Word – it’s just called Hidden and let me show you how to use it to hide text in Microsoft Word 2007. It’s a simple single click process. Open the docum...

Boom, the startup that wants to build supersonic planes, just signed a massive deal with Virgin

Have you heard about Boom? Boom is a relatively new startup that’s aiming to build something pretty crazy. They’re not building an app… or a social network… or even some new gadget for the Kickstarter crowd. Boom wants to build planes. Really, really, really fast planes. Specifically, they’re trying to design and build a supersonic passenger plane that goes 2.2x the speed of sound. If all goes to plan, they’ll be able to shuttle people from New York to London in 3.5 hours, and SF to Tokyo in 4.5. Sound crazy? I wouldn’t disagree. It’s worth noting that the company is in the very early days for something as intensive, massive, and hugely expensive as designing and producing a passenger aircraft. They’re still working on their first prototype, and hope to fly it by late next year. But it’s also worth noting that the team behind the plane has some serious talent in its blood: the company’s 11 employees have collectively contributed to over 30 aircrafts — having worked on thin...

Fun Tools to Translate Your Name into Japanese Calligraphy

Japanese calligraphy is an artistic writing style of the Japanese language. Its Chinese origins can be traced back to the twenty-eighth century BCE. Calligraphy found its way into Japanese culture in 600 CE and is known as the karayo tradition. For Westerners, calligraphy is forever fascinating. However, it takes years to learn how to properly draw the signs. Two basic principles must be known to understand Japanese writing: there are different writing styles and different alphabets. Kaisho for example, is a writing style most commonly used in print media. Tensho on the other hand is used in signatures. Other writing styles are Reisho, Gyosho and Sousho. The alphabets include Kanji, Hiragana, and Katakana. Katakana is used for writing foreign words. It can also serve to highlight words, in analogy to capital letters as we know them from the Roman / Latin alphabet (Romaji in Japanese). Each Kanji character has a meaning of its own, while Hiragana or Katakana characters merely repres...
