A team of Berkley graduate students designed a solar hot water heater for low income households. They built heaters and tested them in Guatemala. It was a success and they are hoping to have more built in Guatemala and they are looking at doing this throughout several third world countries as a means of stimulating the economy. That’s all well and good. What I want to know is, why not do this here, in the USA? Our nation is in need of job stimulation, other than Walmart, too and there are enough low income families right here that could benefit from this solar hot water heater. I don’t begrudge third world countries getting renewable energy resources. If the economy of this country doesn’t start turning around, this nation will become a third world country and perhaps then we will qualify for low cost solar hot water heaters. Why should we have to wait until then?
