Well, got back from my boots on the ground trip with a SBUX in hand. Drove by miles of solar farms going up near my home. Doing this exercise reminds me of the huge potential here...BRK does not put money into things that are losers...big money is in this, but not all big players understand this potential..
That is why I am holding long my solar sector and some day, it will be one of the best sectors...
Think of it...sun power turns into electricity...it is what is running this comuputer right now...pretty cool.
