    Hello :)

    I woke up with a question today... as we are in the green age and everybody is focussed on low power consumption and low emissions.... what can we do with tomato to reduce power consumption & maintenance costs?

    The things I can thing about to the top of my mind are:

    - underclock the cpu
    - decrese the wifi transmission power

    Is there anything else to consider?

    p.s. is CPU dynamic frequency scaling possible?

    Thanks :)

    The RT-N16 comes in at a whopping 10 watts. I'm not sure it's a factor here. =)

    If that's the case then why are the folks at the "other firmware" forum recommending a 2amp or bigger power supply? :biggrin:

    Kidding aside, mine is running cool with an external hard drive attached without external power, and the stock power supply.

    Because those folks mistakenly believed that 2 amps couldn't possibly power the router plus two powered USB ports.

    Now when you consider that the *maximum* draw on a USB port is 500mA...well, let's just say that lack of power wasn't the issue.

    In fairness, the majority of people have no clue about the most basic of power calculations or electricity in general. That's why we've got moulded plugs these days :)

    My RT-N16 apparently draws 10W continuously.

    Origin energy here in QLD (Australia) have a standard tariff of 21.351 cents/kWH

    365 days per year * 24 hours per day * .010 KW * .21351 $/kWH (Origin Energy) = $18.70 per year to run.

    PG&E in the US .. Electric Schedule E1 (Residential Service) - tariff is $0.12233 $/kWH
    365 days per year * 24 hours per day * .010 KW * .12233 $/kWH (PG&E) = $10.71 per year to run.

    These routers work better with a 1 Gigawatt nuclear generator, an arctic cooler heatsink, and the biggest fan you can find (at least 7500 rpm). Everyone knows that :biggrin:
