unless you are certain that it will run dual voltage. I just moved from the US to Germany. I had no problems with the power supplies in my equipment (4 laptops, 6 PCs, 1 UltraSparc) HOWEVER - two very annoying bits that I had not considered:
US purchased printer would not work on 220V without a power supply replacement (which can only be purchased from printer parts suppliers and swapping it out voids your warranty). Not an issue if you don't print I suppose.
UPS. After many power outages in the US in several different East Coast locations (Boston, Washington D.C., and southern Virginia) I had come to rely on my UPS (from APS). After shipping the 50 pound battery across the Atlantic, only then did I realise that it was not compatible with 220V! Quite a surprise that you should not have to deal with (not the power outage which you should expect, but the lugging around of a 50 lb battery)
By the way - don't forget to check the voltages on your networking equipment. Most of the modern network hubs, switches, etc. will be ok for 110-220V, but you'll need several adapter plugs or power cords (if you're lucky and the cord can be swapped). Or replace the power supplies with "universal adapters" - something like this is inexpensive ($14).
Regarding extension cords and "power strips": I had brought my "high quality" power strips from the US - the ones with built in surge protectors - in hindsight it's no surprise that the "extra" 110 V is considered a surge.
So now I have a pile of extension cords and power strips that are completely useless.:(
One more tip: Before you go and purchase conversion plugs for your equipment, you may just want to purchase new power cords ($2.50) that are usually cheaper that the conversion plug ($15), plus it will be the proper size for US outlets. The UK plugs will usually make every-other outlet on a US power strip unusable due to the size difference.
In 1978 the Rand Organization was commissioned to create a "new" transportation method, and they published this exact topic. Their publication is available from their site: Rand Org.
A *very* high speed maglev train that travels through tubes where the air has been evacuated to eliminate air friction.
Here is the abstract from that page:
Abstract: Describes a subway concept called "Planetran" comprising electromagnetically supported and propelled cars traveling in underground evacuated tubes, able to cross the United States in one hour. It is designed to interface with local transit systems, and the tunnel complex also contains utility transmission and auxiliary freight-carrying systems. Tunnels represent a major problem area and most of the cost. They will be placed several hundred feet underground in solid rock formations. It will require advanced tunnel-boring machines, such as hypersonic projectile spallation, laser beam devices, and the "Subterrene" heated tungsten probe that melts through igneous rocks. Planetran is rated as a system high in conservation of energy. For every car being accelerated, there is one decelerating in an adjoining tube. The decelerating cars return energy to the system. The tubes have a reduced atmosphere, making drag losses much smaller than for aircraft. Coast-to-coast energy costs are expected to be less than $1.00 per passenger.
Yes, companies really do this, and it gains the big ones that implement intelligently millions of dollars per year.
How about a few analogies to explain the "supposed" benefits:
It's like using a network file server instead of using floppies to move files between computers.
It's like using NIS to sync all your users instead of adding every user manually.
There are many benefits to using an ERP system, with most people finding the most benefits in a manufaturing company. It would be swell if there were only two fields to fill in to run ERP software (employees and sodas), but there are usually hundreds.
I used to implement ERP software(SYMIX,Glovia (CHESS),Baan), and then programmed for Baan...The software is big and does so many things. "Enterprise Resource Planning" _is_ descriptive. For your entire enterprise(business) - whether one site or a hundred sites of hundreds of employees, machines, departments - you can manage/decide/plan how each of those resources (including money) should be allocated and assigned to achieve your business objectives.
