Actually, composting toilets are a 'thing' : http://www.humanurehandbook.com/downloads/humanure_sanitation_paper.pdf (sanitary engineering/science whitepaper; main website: http://www.humanurehandbook.com/)

They can even be used in mobile installations e.g. class b (medium/small) RVs.https://www.thefitrv.com/rv-tips/the-straight-poop-on-our-composting-toilet/

I've read about that. Downloaded the book (2nd edition at https://humanurehandbook.com/)

Sorry, but why do you shit in drinking water to begin with? Just use a compost toilet. The composting process kills almost every known disease, and if it is your own toilet, you know what diseases went in, so you know what can come out (it probably won't, and if it does, your body has learned to cope with it). It's literally dirt cheap, low-tech, and can be implemented almost anywhere. And you get better compost as well. See the Humanure Handbook for all the details.

Sounds like something straight out of the humanure book.

IIRC, the compost in a properly setup and maintained system will destroy pathogens, at least according to the tests the author did.

IMO, the technology/cost of this biochar system seems like it could, in most circumstances, be spent better elsewhere, since a humanure setup should cost less and be able to be built with mostly local materials.

I suppose you mean humanure. See the Humanure Handbook. Not exactly rocket science, and it is widely tested on earth.

Please do. Western people use their own manure to pollute the seas and then spend money on chemicals to give the soil what the manure should have given it. If you use a compost toilet, you save the environment in a lot of ways and also a lot of money (like the money spent on sewage treatment). There's a nice book about it. You can download it for free at http://humanurehandbook.com/ (link on the left of the page).

Greywater only contains a little poo, hair, and used toothpaste. See also: Humanure

if the ultimate consumers were to make it themselves rather than outsource its growth or manufacture.

There are some good solutions in The Humanure Handbook. That does not change corporate agriculture, but a little awareness on our behaviour is a good thing.

As Mark Boyle (The Moneyless Man) once said: if we knew how hard it was to purify our drinking water, we sure as hell wouldn't shit in it.

How about teaching people how to use a 5 gallon plastic bucket, some sawdust and their kitchen scraps to compost their poop.

No water needed. Your poop and kitchen scraps already contain all the water needed for a thermophilic reaction. Furthermore, you get nice compost that these people can use to fertilize their land. If not for growing things they can keep their land from turning into desert.

Also, *everything* organic goes into the compost pile: fats, oils, bone, meats, fish, urine, etc., etc.

There's thousands of folks already doing this in the US. We need to stop using purified drinking water to whisk away our poop.

What about Composting sawdust toilet I'm sure the locals have something they can use in lieu of sawdust.

You could even create a dehydration toilet Urine is collected separate (where it could easily be evaporated off and the urea used as fertilizer). After dehydrated the human waste could take place of animal dung used for heat.

I think a bigger and better use of this money would be something to sanitize. Something as simple as soap or the 'waterless' alcohol based sanitizers.

Organic vegan agriculture can and is being done.

These are the same methods that I currently practice in my garden.

Animal derived inputs are not required to grow plants. If you do want to add some animal inputs there are animals on the site of most gardens/farms, they are typically running them. You might also want to read this:

Joseph Jenkins --author of the Humanure Handbook-- has been doing this for close to thirty years. His concept also has the benefit of being patent free and simpler. Look see here:http://www.jenkinspublishing.com/humanure.html

All you need is a 5 gallon bucket, some cover material (rice hulls, sawdust, shredded newspaper, or coffee grounds), and teensy bit of brain power.

You can get the book on Amazon or download it for free from his site: http://humanurehandbook.com/downloads/Humanure_Handbook_all.pdf

After reading Joseph Jenkin's excellent book, The Humanure Handbook (http://www.jenkinspublishing.com/humanure.html and available for free here: http://humanurehandbook.com/downloads/Humanure_Handbook_all.pdf), I've been doing a lot of thinking recently about not just human waste but the waste that comes from everyday computing.

I think what you and I want is the combination of a Beagle Board and a Pixel Qi display (http://www.pixelqi.com/). That display has been mentioned on Slashdot before. You could also start developing super efficient programs on something like a PC Engines ALIX board (http://www.pcengines.ch/alix3d3.htm) or a Technologic Systems ARM based board: http://www.embeddedarm.com/products/arm-sbc.php#ts-7800-series The TX boards come with Debian pre-installed and boot up in less that2-3 seconds. They seem to be very hacker friendly.

Of course, the other side of the equation is the WWW that we connect to. Is there anyone giving any consideration to efficient computing on the server side? Web forums vs. mailing lists; fancy web sites vs. lean, mean, and candid web design? Are there resources online where I can learn how to design a lean, mean, yet somewhat modern looking web site and run it off something like the aforementioned ALIX (500 Mhz AMD Geode) board? Does HTML help at all in this regard?

I even miss the old but lean Slashdot of long ago.
