hyperlearning travel headgear

When people travel they frequently see lots of new things as well as gain some greater fluency at language. There are a variety of published items (DARPA, Science magazine) that suggest double or better learning or recognition from tDCS Transcranial DC Stimulation near 9v at 2 milliamps. Thus the idea is just glasses or headgear that sense if you are having a pleasant time then turn on the tDCS while travelling. That way you learn more things, yet perhaps also retain the I like it ness of travel as a result of the software only turning on the hyperlearning when you Like your surroundings. Notice more sight, gather more data as you travel, possibly also learning language much faster.

Also as TMS (transcranial magnetic stimulation) is already used to improve mood it is possible that Learn only when pleasant tDCS headgear could be an even more effective voluntary mood improving treatment.

Now I recognize that Use another persons research then make it a travel technology is not much of an idea yet the prospect of knowing twice as much Europe from a visit to Europe seemed worth the "thats not an idea!" risk. Also if I had said Put an LED on a bike so it could be seen that would be rather obvious as well, yet obviously of value.

This idea is so tremendously derivative that I am describing another idea immediately.

also at the compatability gadget area, would two people with these communicate more effectively

I wonder if you were wearing hyperlearning headgear, and people could tell, would they modify their behavior around you? If it actually works would people put a merely skin implant on the sides of their heads that could be recharged with EM?
