Fujitsu To Show Off "Zero-Watt" PC At CeBIT
mobile writes "In August of last year Fujitsu announced new 'zero-watt' displays. This means the screens use absolutely no power when put into standby mode, unlike most other screens that use less than 1 watt, but still require some power. Now Fujitsu has announced they will be showing a zero-watt PC later this year at the CeBIT show. The PC is called the Esprimo Green and marks a first, in that it's able to use no power while in standby mode — but this is a feature that will be required from 2010 for new PCs released across Europe."
How would you know whether the device is in standby or turned off? Normally an LED signifies this.
Perhaps a mechanical indicator? Or, e-ink?
No the summary says they introduced zero watt displays LAST YEAR. The new thing that's going to be introduced is a zero-watt PC.
>It can be. The "wake-up" signal that the net, Wi-Fi, or Bluetooth gives it could give it enough power to switch it back on.
Nice try, but no.
Twisted-pair Ethernet requires 2-way signalng, at about 1 volt across 200 ohms, 5 milliamps, 5 milliwatts. It's mighty hard to run a 100MBPS modem and ethernet frame detector on 5 milliwatts AND send 5 milliwatts back all the time.
Wi-fi and bluetooth deliver picowatts at best. Not enough to power the receivers.
Buy, a router-HDD-WLAN combo for $180 top (can't get more expensive than the AirPort Extreme) or use a old notebook for that (which can also do audio and may cost nothing). Either one will consume about 20W (including additional HD for file-storage) instead of the 40W your computer is going to consume the least. The 40W does not account for an gaming capable graphic-cards or processor, in which case your computer easily consumes 100W-140W idle.
Assuming, that the computer consumes 100W 8h per day and 25cents per kWh, it translates to $160 saving per year.
