My dad's contact in Gaviotas has a son exactly my age, Ricardo. He speaks English very well, so for the next week, he was my guide to this amazing place. The first thing he pointed out to me was all the fantastic technology that had been invented there. That was why my dad was there, I could see why he was excited. They have these and great windmills to generate power and solar panels to heat They even use cow dung power hospital told me that they produce of all their own energy and food, and they produce very little waste. The trees they planted more than compensate for greenhouse gases they emit. What's more, the technology they've developed here is used in several other places Central and South America, and they don't charge peso. It's free for everyone.
