A Physical Key to Your Google Account

Mark Zuckerberg buying Oculus has laid news emphasis on virtual reality, hardly a new thing. The scale of the discussion has changed irreversibly.

Bringing Burning Man to the masses through virtual reality, now that's a thought.

Drones for a few hundred dollars. Virtual reality headgear for a few hundred dollars. "Don't underestimate the power of the common man!"

The Quest to Put More Reality in Virtual Reality

After the initial unfamiliarity wore off, chatting with Rosedale and Karpf in virtual space was much the same as it would have been in real space. ..... The impressive 3-D headset being developed by startup Oculus VR, acquired by Facebook in March for $2 billion, has spurred new work on virtual-reality hardware by startups and established companies such as Sony ...... hanging out in virtual space will become a new form of mass-market entertainment. ..... Second Life .. “We did our best and got to a million people and made half a billion dollars [in revenue] or something” ..... Rosedale still logs into Second Life from time to time (his avatar is younger and slimmer than he is, with a muscled torso). So do about 1 million other people each month, and Linden Lab remains profitable. But hanging out in a free-form virtual world didn’t become mainstream, as its founders had hoped. ........ people donning Oculus headsets to dip into quick social interactions or strange environments. ...... virtual worlds will open up a new era of human existence ..... the freedom to explore and experiment inside a virtual world generates a “social force,” creating positive interactions between people that are impossible in everyday life–much like the Burning Man festival he attends each year ...... When I met Rosedale in that virtual club, his avatar’s eyes sometimes darted wildly to the side because of glitches with the face-tracking technology. ...... popular enthusiasm about virtual worlds is surging again thanks to Oculus ...... Rift goggles, due by 2016 .. All are expected to retail for only hundreds of dollars. .... “Imagine sharing not just moments with your friends online, but entire experiences and adventures”

Energy Is The Biggest Security Issue

If Washington DC sends out the right signals, looks like defense companies do respond and start reallocating their resources.

Does Lockheed Martin Really Have a Breakthrough Fusion Machine?

Nuclear fusion could produce far more energy, far more cleanly, than the fission reactions at the heart of today’s nuclear power plants. ..... If successful, the program could produce a reactor that might fit in a tractor-trailer and produce 100 megawatts of power ...... with research partners Lockheed could develop a competed prototype within five years and a commercial application within a decade. The company is even talking about how fusion reactors could one day power ships and planes.

Clean And Expensive

There is a tipping point in the Climate Change debate where clean energy starts competing in price with dirty energy.

Why Solar Is Much More Costly Than Wind or Hydro

no surprise that if environmental costs are considered, renewables—particularly wind power—are a far better bargain than coal power. But it might surprise many that according to a new such analysis, solar power lags far behind wind and even hydroelectric power in its economic impact, at least in the European Union. ........ the economic costs of climate change, pollution, and resource depletion as well as the current capital and operating costs of the power plants ....... a metric ton of emitted carbon dioxide costs around €43 ($55). ...... many of world’s solar panels are manufactured in China, where electricity is very carbon-intensive ...... new coal and natural gas plants in the E.U. have levelized costs of just over €50 ($64) (in 2012 euros) per megawatt-hour (assuming they are running at maximum capacity); onshore wind is around €80 ($102) per megawatt-hour; utility scale solar PV is about €100 ($127); nuclear power is around €90 ($115); and hydropower is as cheap as €10.
