Workplace has no power. Is it possible to work thin clients without power supply?

a few ideas:
- portable computers: laptops, netbooks.
- handheld devices: smartphones, tablets, Nokia N700-N810
- very low power mainboards (VIA or ARM) hooked to an UPS.
In the end, you'll always need some power:
- for the server (unless it's remote)
- for the network (switches, access points, router if server is remote)
- to recharge batteries (either internal or on UPS)
If you try to go PoE, note that the distance is limited; Ethernet UTP itself goes up to 150m, but to get PoE at high wattage more than 50-70m you need higher voltages at the source. A lot easier would be to lay your own power cable as you do the network.
tl;dr: electronic devices use electricity. might be low amounts of it, but never zero.
If you found computer with 15 Wt consumption.. PoE can give you only 15 Wt... I don't see any another way...

it's not hard to find linux-capable ARM boards that consume far less than 15W (heck, even some VIA boards fit!). the huge problem would be to power the display.– JavierFeb 25, 2011 at 14:24

@John Gardeniers: assuming the server does have power available, you could power the switch at that central location.– JavierFeb 25, 2011 at 14:26
