Where does it say these are electric?
I assumed a maximum power consumption of 30 watts and I think that is pushing it. If the printer for some reason is in graphics mode you are looking at a minute or two per page and event at 30 watts you risk depleting batteries.
Line printers??? Do you realize how much power those things take? I'm assuming he has a power budget of 30 watts or less. If it wasn't for that restriction I'd tell him to go with a good dot matrix printer.
I don't think there is a modern printing technology that can meet the requirements. Lets take a look.
Dot Matrix Impact is out due to excessive power.
Thermal is out due to longevity issues of both supplies and the actual printouts.
Laser/LED is out, again due to excessive power.
Daisy Wheel is out due to lack or printer availability. Not sure about power.
Ink Jet would only be feasible if you can find one that takes cheap ink, these take little power.
WWVH also operates on those frequencies. It is possible to hear both at the same time with good conditions and a good antenna. As a user of HF spectrum this is a valuable resource.
Adjustable desk lamps can't take the weight of LED bulbs due to the heat sink. They always droop over from weight of the bulb.
Simple, a mass SMS would overload the network in a situation where the network is stressed. Plus it takes longer to determine all the numbers that need to receive the message.
Modern Incandescent lamps no longer use lead in manufacturing. If you include the energy used during manufacturing and transport incandescent lamps are rather energy efficient as little aluminum is used in the base and there are no plastics, semiconductors or other materials that use a large amount of energy (or are made from crude oil) used in the manufacturing of incandescent lamps.
Mod Parent +5 funny! Anyway as of the last time I was in my auto I was getting 532,224 rods per hogshead which is low compared to 544320. Of course I've been driving where the speed limit ranges from 27,200 furlongs per fortnight to 107,520 furlongs per fortnight. However when the school zone lights are flashing it is a piddly ass 40320 furlongs per fortnight even in a 107,520 furlongs per fortnight zone.
If I was allowed to leave a gun in my car at work I would get one too. Problem is it is against FEDERAL LAW to have a gun where I work unless you are authorized (military installation).
I don't know, but whoever was wanking around on my slashdot account and trolling around will have a more difficult time. I just changed my password.
After an instrument has been assembled, extra components will be found on the bench.
