I have connected a normal joule thief to my earth cell in a pot. The power was not strong enough to light the led but if i touch the resistor just before the base transisor, it give a sort of spike and light the led. It works without shaking the joule thief but if i shake it, it "recharge" faster.
You can find some on every electronic website or on ebay.

Nice setup. I am interested.
Where did you buy the breadboard you have your circuit on?
