Micro-Shocks (and QRP Power?) from Nearby High Voltage Lines (video)

I spotted this on Hack-A-Day.  It caught my attention because many time, while riding my bike along the Washington and Old Dominion bike path, I have felt electrical shocks from the handlebars. 
Now, before you all conclude that OM Bill is losing it and start suggesting that I wear an aluminum foil hat, realize that the bike path is directly under some seriously high voltage power lines.  And that esteemed UK newspaper "The Daily Mail"  confirms that these shocks are, as the kids say, a thing.

So think these Russian dudes are onto something.  How long will it be before the QRP community starts exploiting this power source?   (Please be careful about where you put the antenna!)
