@neno2010ist1 Absolutly…in places like Latinamerica, India, South East Asia, the Middle East and Africa, family planing should be a top public policy..overpopulation means having to distribute more resources to a larger population feeding misery…In places like Venezuela or Brazil it becomes obvious

i think the greenest idea out there is using china as an example and only having one or two children, i belie that overpopulation is the real problem

simple batch solar water heaters can be built for very low cost…50 to 100 dollars..but american electric and gas companies will tell you they dont work….they cant make money off free hot water…..btw water heating is aproximately 1/3 your utility consumption….lots of free plans on ytube…

@Gr8stuffis I’m thinking that they do not want us to use these heaters in the usa. There are soo many lobbiests in dc that it won’t happen here until they bleed all the money from us that they can. (gas and elect.) I think its better to make your own unit and use in your system. a batch heater is probably the easiest way to go or poly pipe.

I come from Rizhao. People there are using solar water heaters extensively only because it’s cheaper than gas or electrical heating alternatives. That’s it.

@rrXIII Well how can the government here subsidize us to have clean energy, when they take our money to give to failed auto companies, banks, AIG execs and GMO corn and soy to make all of us sick to give their buddies at the pharmaceutical companies a lift?

@rrXIII Hi, I am wondering where you get the $500 figure? Earth Policy Org has the figures at 4000 Chinese Manufacturers that have supplied 27 million Chinese homes for around $200 per unit.
I am wondering how much the 90% or Israeli homes units cost?

Yes, but how do you get one of these in the united states? so far the lowest cost I have found for a system is $2500. and requires solar panels

That machine can be subsidized here in Canada. I also heard they use it in a massive scale in London.
