Comment Re:Small 3D transistors (Score 1) 120

You were talking about integrated microchannels for cooling, right? Or through hole vias patterned into the die? That's what I'm talking about. Digging holes in the crystal and/or depositing metal both cause the wafer to warp.

The more 3D features you pattern onto a wafer, the more mechanical stress you create. This is especially true when you integrate features with different materials and different coefficients of thermal expansion. Such features can increase the warpage and bow of the wafer to such a point, that the fabrication equipment can no longer handle the wafer. It becomes like trying to feed a potato chip into a CD changer.

The larger the wafer, the worse this problem becomes, and today they're running very large 12" wafers that are quite sensitive to mechanical stress. Also, the SOI wafers are more prone to warpage than single crystal silicon.

So, the *real* 3D integration you're taking about is very difficult.

Submission + - Google invests in 392 MW solar power tower (gizmag.com) 1

cylonlover writes: Google has chipped in a US$168 million investment in what will be the world's largest solar power tower plant. To be located on 3,600 acres of land in the Mojave Desert in southeastern California, the Ivanpah Solar Electric Generating System (ISEGS) will boast 173,000 heliostats that will concentrate the sun's rays onto a solar tower standing approximately 450 feet (137 m) tall. The plant commenced construction in October 2010 and is expected to generate 392 MW of solar energy following its projected completion in 2013.

Please stop blaming the O/S. In my experience, malware problems are 1% system + 99% uneducated user.

I've run every version of Windows since 3.11 (and a few versions of DOS before that). Never had so much as a single malware issue. I'm sure many here would say the same.

Maybe every O/S installer should end with an exam. If you pass the exam, you get admin. If not, you get a 1-800 number.

Adult fantasy can become popular, if you don't bore people out of their chairs. Watchmen was a horribly long, boring mess. Heroes is another example. It was painful to watch the last couple seasons. Folks might consider taking notes from HBO. TrueBlood = wildly popular adult fantasy. We'll see about Game of Thrones... looks cool too.
