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.

Silly Americans. Everyone knows you should stick to low- OR high-endian.

Facebook's killer app: baby pictures. The 50-something women - a demographic that is big, wealthy and hard to reach in the net - just love to see their grandkids, comment on how cute they are and share the pictures with their friends.

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.
