Comment Safety issues with grid tie-ins (Score 1) 579

One huge difference between attaching something to the phone network and direct back-feed connections to the grid is that the back feed can be deadly if there's an issue with the local distribution network. This is usually taken care of by the anti-islanding circuitry in an inverter designed for grid tie use, and the utility has both the right and duty to make sure that circuitry is present and working in any grid tied installation.

Comment Peak demand time (Score 2) 579

FWIW, the peak demand in California typically occurs about 6PM, well after most PV installations fall off the grid (peak production from solar occurs at 12noon and solar output is largely gone after 3PM). This data is from the California ISO website. This implies that grid tied PV solar without some sort of power storage is NOT an effective source of peak shaving.

The first thing the rural utility co-ops did was to tell prospective customers that they had to render their windchargers permanently in-operable. In a similar vein, many cable companies required new subdivisions to have CC&R's that prohibited external antennas so that the residents were forced to buy cable services.

Comment Re:Look up those words before you use them (Score 3, Interesting) 363

Obviously you have never taken a look at the California ISO website during the summer, which gives real information on demand and production. as opposed to rants of solar fanboys writing for Wikipedia. Peak production from solar occurs at 12 noon, peak demand occurs at 6PM. Solar does help with energy production during the hottest part of the days but is no help when demand is highest and thus does nothing to reduce the need for spinning reserves.

FWIW, some of the strongest stories about problems in firing teachers were published by the LA Times while it was part of the same organization that owned the Chicago Tribune. One recent case was the teacher who was giving his students cookies laced with his semen. The two propositions that were mentioned in TFA were sponsored by the Cal Teachers Union.

That won't work the way you think it would. What you're describing is a line scan, which gives a 2-D image of the container/truck, which has been deployed. A CT scan gives a 3-D image, necessitating some way of moving the x-ray source and detector around the container while the container is moved through.

There are a couple of reasons why the object being scanned is rotated on a turntable rather than the source and detector rotating around the object. First is the high energy X-ray source is friggin' heavy. The second is that having a stationary X-ray beam allows for concentrating the shielding in a relatively small volume and we're talking some pretty serious shielding.

no, thats NOT good. that means that you can be personally sued for anything that goes on with the company.

Since the lawsuit was filed by the Federal Government, let's carry this a bit further. If any employee of the Federal government (this includes judges) can be shown to have caused harm through malfeasance or negligence, then that employee can be held personally liable for the decision. Think anyone would want to work for the government under those conditions?

The Great Influenza by John M. Barrie goes into great detail how the war time censorship under the Wilson administration resulted in a significantly higher death toll in the US. The so called "Spanish flu" got its name because the Spanish press was not censored, the flu appears to have originated in western Kansas.

Comment Re:Light aircraft diesel engines (Score 1) 366

Packard built a radial diesel ca 1930, so there's no technical reason that a radial engine couldn't be built. The impediment is that the market for large (2,000 to 3,500 HP) radial diesel engines is not large enough to justify the costs to design and build such a beast. An L-1649 or a DC-7C with radial diesels would be cool, though the pax may not care for 20 hour flights...
