Glaskowsky takes on the latest loony idea for energy generation.
Glaskowsky takes on the latest loony idea for energy generation.
Web sites launch all the time, but they also shut their doors. We highlight 15 that bit the dust this year.
Let the debate begin: Was the iPhone more important than iTunes? Was anything bigger than Google finding a great business model? CNET offers its list of the 10 most important stories of the '00s.
Silicon Valley-based computer architect and chip analyst Peter N. Glaskowsky attends a variety of industry conferences throughout the year to meet with industry thought leaders and dig into the future of computing technology. In Speeds and Feeds, he analyzes trends in system architecture and interface design, as well as market and political pressures surrounding those trends. He is a member of the CNET Blog Network and is not an employee of CNET. Disclosure.

I know you from Jerry's site. I'm "Phil". You asked about cameras a while back. I've been using the EOS20D for 3 years. I've got little ones and the DSLR's capture those "moments" that the point and shoots can't. Canon just released a new pair of pro and pro-sumer DSLR's. The EOS 1D Mark III and the EOS40D respectively. You can get EOS 1D Mark II's on Ebay for about 2300.00. If you look carefully, you can find another avid amateur trying to sell up to the Mark III who has a low shutter use Mark II for sell. You should be able to find one with 10K shutter actuations or so verses the Pro's selling up with 100K actuations. I did. After receiving my Mark II, I can tell you that it is what you want. Fast and built like a tank.
On lenses. Get Canon L glass. The 24-105 F4 L is a great start.
My 3.14 cents worth.

- Without arguing the specific merits of the windbelt idea, Peter's dismissal of the technology is a bit misleading... he says that "It would take at least 5 watts of power to produce enough LED light to replace a kerosene lamp". While this may be true, the fact is that all that power doesn't have to be produced at the same time. Just as Peter recommends solar cells, which collect power throughout the day to be used at night, the windbelt (or any other wind powered micro-generation unit ) only has to collect enough energy to be used for the few hours before the family goes to bed. And if the wind continues blowing at night, then all the better! Also, a single kerosene lamp is not a particularly efficient light source in the sense that it's light coverage is indiscriminate and single-source. Rechargable LED headlamps for each member of the family would consume LESS power than the kerosene lamp since all the light produced would go toward lighting each individuals specific needs..
