LCD pwnz-o-rama: Sony ships first OLED - constrast ratio: 1 million to 1.



It's here friends, Sony's Drive teaser is none other than their 3-mm thin, 1,000,000:1 OLED TV, just announced official with a December 1st Japanese retail date. The 11-inch SonyDrive XEL-1 set features a 960 x 540 pixel resolution, terrestrial digital tuner, 2x 1W speaker, and HDMI, USB, and Ethernet jacks in a package measuring 287 x 140 x 253-mm and 2-kg (3.3-pounds). How much? Well, ¥200,000 or about $1,740 - That's about $160 per inch of OLED. Rich indeed, but so it goes for first generation technology.

Prices will come down. And when they do... oh boy are LCDs gonna die like the crap they are.

Betavoltaic batteries - so your laptop really will glow in the dark!



The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years. Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell.

The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world's most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.

That is pretty spiffy! The kind of tech I want to see in the year 2k7. I wonder what the energy density of these betavoltaics is? The article throws up a lot of green-washing BS ("they're not nuclear" - oh yes they are; "disposal is not a problem!" - most likely it will be) but still, pretty cool tech. This is kinda like a better version of the radioisotope thermoelectric cells they use to power satellites.

LOLI HAET JAVASCRIPT


Sometimes people say to me: "Ben, why is it that your hatred of JavaScript burns with the white-hot plasmatic fury of 10,000 supernovae?"

And I say, "($PERSON), I'm glad you asked. Let me give you an example..."
