Good idea; let's hope someone is working on this right now.......

You can't stop Google logging your searches, it seems, unless I've not read between the lines correctly? See the "However" caveat:

"You can remove all Web History from your Google Account at any time. While signed in to your Google Account:

NB The banning of lead in solder is another example of EU over-reaction IMHO. The likely consequences ( higher failure-rates in electronic products) represent a possible ticking bomb.

Who will rid me of these obsolete PCs?

Re Nup on AC

Sadly, your pithy "Power is Power" explanation is a tad over-simplistic : in AC circuits we have reactive currents as well as resistive: the former do not result in power dissipation. Hence the importance of power factor when specifying many higher-power electrical devices. Of more relevance to the SMPS example given here is the nature of the mains current waveform, which is highly non-sinusoidal, and thus the rms current x rms voltage equation does not yield true (i.e billed) power consumption. The typical error factor is in the range +50 to +100% .
