Nobody ever poops at my party, I wouldn't allow it.
100% self-sufficiency (totally) is possible but not probable and is to some extent inconvenient. I would like to be a dependent as possible but I do want my washer and dryer.
honda has a water powered car, check out the website. There has been commercials for it too.
Another company makes a totally electric one called a Tesla, it's faster than a Porche.Not cheap though, but they are working on one that is around $20,000. Again look at the website. Google: Tesla electric car.
Already built a earth sheltered home for an other couple in Oklahoma. Worked out great for them. House is almost completely underground and they do not have a/c or heat unit. Stays 65-70 degrees year round. They do not have to worry about tornados (we get them). They have a well and septic. They are on the grid but with the wind here, whey will be switching over to wind power soon. At that point, no utility bills either, except satellite for internet cable and phone service. Cost for just the house was about 20,000 and another 20,000 for 10 acres. House and land are paid for in full with the proceeds of their previous house. No house payment, credit card bill, car payments, outrageous utility bills at age 42, not bad in my book.
it is Iceland that has completely banned anything but HYDROGEN cars in their country. My mistake. It was on the National news. Go to ABC they still have the story on there, I just checked

i love the internet. info at your fingertips!
So, is has indeed been done and is working wonderfully for them. Can't imagine the oilman we call Bush would have anything to do with the snails pace in the independence from foreign oil.
Biodiesel is stupid on many levels.
Sorry about the grammer, punctuation, etc in my posts. I am usually doing 20 things at once and really didn't think the conversation in the forum was that formal.
I live in a town of 70,000, where the median house is 250, 000 (pretty high for Oklahoma standards) and more than half of the adults are college grads, including my husband and I.
We are trying now to live as much as possible as self reliant and still be sane. Recycling, reusing, etc and NOT trying to keep up with the "Jones". No credit debit, no car payments, etc. Hard to explain to those who don't have the desire to not work your butt off all your life just to have the basics or to have enough "stuff" that you don't feel like the freak show of the town.
I noticed you are from Canada, this explains alot of your "infeasibility" issues. You don't give human kind credit where credit is due.
Cheers to you!
