So engineers are roughly half as unemployed as compared to the whole country. Sounds like you need more of them. Unemployment rate 4.5% is also approaching the viable minimum rate. It's just not possible to have a 0 percent unemployment rate since there are always people moving to different parts of country or somesuch. It's called frictional unemployment. So yeah, you need more.

He was, and he wasn't. If you specify a stop-start system when ordering a new car you also get a beefier battery automatically. The systems also monitor engine temperature and current running time and do not stop the engine if the engine hasn't been running continuously for at least 10 minutes after the start of the drive, or the engine temperature isn't high enough.

Rovaani (20023) writes "(via The Nokia Blog). Here is a video of a Nokia N900 smartphone running the full desktop Mac OS X 10.3 From the author, Tomi Nikkanen: "I believe this makes the N900 the first smartphone EVER to run the full version of Mac OS X (at any speed, slow or otherwise). As you can see from the heavily edited video, it took almost 2 hours to reach the "About my Mac..." window. Keep your eye on the time display as that will give you an impression of just how uselessly slow it is. ""

+ - Roman Army Knife predates Swiss by 1800 years-> 2

Submitted by Anonymous Coward
An anonymous reader writes "The Daily Mail describes an "intricately designed Roman implement, which dates back to 200AD... made from silver but has an iron blade. It features a spoon, fork as well as a retractable spike, spatula and small tooth-pick. Experts believe the spike may have been used by the Romans to extract meat from snails." But is it a Roman Army Knife, or an Army Knife of Rome?"

The obvious solution to this is to separate the distribution to a separate company, as in district heating. The power grid company already deals with hundreds of residencies and maintains the grid.

And if you are doing the infrastructure from scratch you can do trigeneration relatively cheaply for district cooling.

Cogeneration (or combined heat and power) can increase the efficiency of fossil fuel plants by a factor of 2 (from 50% to 93% efficiency mention in this Times article). The downside is that the the piping infrastructure investment needed is huge. Maybe this data center powered heating scheme can give it a leg up.
