I didn't buy in to TNG as a true believer. Pure speculation. I can't say that the investment has gone as well as I would have liked and I'm currently down 60%. Is that a reflection of my investment style?
I was recently investigating solar storage batteries for my energy set up at home. Storage batteries will be the next thing as long as the govt is un-green and the energy companies only give you a measly 0.08c per kw grid feed IMO.
Batteries are very expensive at the moment and don't last that long Vanadium looks the answer. The fallacy of solar energy is it only works for you if you can store the extra energy generated.Some no doubt will have checked this out before:
