that's why we need to invest in R&D, to make it more efficient, Germany has a solar grid that works wonderfully, and they have half the useable sunlight per square mile as the US If you don't believe education is an investment, then you probably get your news from the dropouts. We don't need to spend more than the next 26 countries combined, how about we spend just a little more than our closest ally and call it a day? We also don't need to be in endless eternal war all over the world, get our troops home, get them real jobs. If someone tries to INVADE us or declare war on us, then let's actually declare war on them, blow them to smithereens, and then bring our people and our shit back home. enough with the world policing, enough with the nation building abroad. Bomb the shit out of them, go the fuck home.
