Take the unemployed into government jobs. Forbid utilities from increasing their price (but giving them "subsidies"). In 3 or 4 years Greece will be a FINE place to live. You'll see a lot of expensive cars in the streets, lots of new buildings, overall support for the government. The president will be re-elected with an overwhelming majority. And in 10 to 15 years Greece will be struggling again. How do I know? Because as an Argentinian, this is what i live with every day.

So Argentina "Atlas Shrugged" itself into an unholy mess? Whoda thunk it?

Sounds like the Obama plan - free phones, free healthcare, free money!

It's advantageous because of the reduced weight of wiring.

The real advantage comes from using electrically-driven valves in IC engines. You can eliminate the camshaft, camshaft bearings and associated holes that penetrate the head, the lifters, rockers, timing gears/chain/belt, etc, and more importantly have infinite variable-valve timing, which is a holy grail of efficiency.

You can also have a much smaller starter motor, as well as smaller alternator (higher voltage but smaller windings due to lower current for the same power output). If you're very clever, you could combine the two into a motor around the perimeter of the flywheel.

In addition, electrically-driven AC starts looking do-able, as well as electrically-driven power steering pumps (already exist - my Mini has it) and water pumps (with this you can eliminate the thermostat - just vary the speed of the pump).

Will all that you could end up with a completely beltless engine with no crank pulley on the front of the motor - the only holes would be for spark plugs and either fuel/air (non direct-injection) or air + direct injection in the heads and the power output shaft out the rear of the block.

Comment: Which is it, artificial or synthetic? (Score 2) 57 57

The article calls the cells 'artificial' and the blood 'synthetic' - I would argue that the cells are not artificial but merely exogenous since they arise from the same stem cells 'normal' blood comes from and are simply grown external to the body (and are indistinguishable from 'real' RBCs, presumably). An artificial cell would be: 1) a cell-like nano-machine manufactured to carry O2, or 2) a living cell derived from other types of cells that has been coaxed into carrying O2 but was not grown from RBC-producing stem cells.

If the non-RBC components of the blood are not similarly derived or do not come from actual fractionated whole blood or plasma, then I agree that the blood is synthetic.

Let's be real here. Radio waves _can_ be harmful. They may seem magical but they really can be damaging if they deposit too much energy into living tissue. For 2450 MHz into a 9 dBi antenna, the 'safe' distance for a controlled environment is 0.518 meters (1.700 feet) - that's an environment where everyone is aware of the radiation and the public is not allowed. In an uncontrolled environment (where the public may be exposed) the 'safe' distance is 1.140 meters (3.739 feet). I put safe in quotes because the existing FCC rules are very conservative.

If you're not familiar with MPE, there are interesting docs available:

Interestingly, the max power you can be exposed to is very frequency-dependent. Freqs that are closer to body-sized parts are more likely to couple to the RF and absorb more power so the max permissible power is lower.
