Biochar is produced through pyrolysis, not incineration. That's a very different, and odorless, technology. (Basically, you burn the smells as an integral part of the process.)
As pointed out several times already, there would be no odor from biochar production: what would produce the odors is burned as part of the process.
Not emphasized, but of great importance, is that biochar sequesters carbon for thousands of years.
Also not emphasized, but also of great importance, biochar is a potent soil amendment. It can recover the health of soils depleted by monoculture farming practices, for instance.
Well, yes, but with this difference: incineration pumps all the carbon in the poop into the atmosphere. Biochar production uses the heat to run a pyrolytic, anaerobic reaction where a good portion of the carbon is turned to charcoal and sequestered away for several thousand years. Since the charcoal retains the microscopic physical structures of cell walls, etc, it also has some very good soil building qualities, such as retaining fertilizers for slow release and increasing the moisture holding capability of the soil.
Biochar production from garden debris burns the gasses it produces; I would expect the same of a biochar toilet. It just makes sense: you have a source of ignition and the burning adds more heat to the pyrolysis process.
In all fairness, though, traditional composting toilets can't handle the volume produced in urban settings. They may be great for homes, but not so much for apartment housing, dormitories, airport terminals, etc. Biochar toilets can be adapted to meet at least some of these needs.
Another point: biochar acts something like a catalyst to improve soil but is not consumed in the process. The carbon is effectively sequestered for thousands of years, but biocharred enriched soils are better at appropriate release of moisture and nutrients while also diluting many soil toxins.
This might seem like the magic cure-all to all post-modern ills, but it isn't all blue sky hype. Each gram of biochar adds the surface area of a tennis court to the soil; a little bit of it goes a long way.
One last point: composting toilets only work well if they are properly managed. I had the misfortune of having a country neighbor for several years who was learning how to manage her composting toilet, and there were definitely episodes of odor problems.
Next year's Pi Day will make all other Pi Days any of us will experience pale in comparison. For it will be
Not only that, but it will contain TWO Pi minutes! The first at 9:26 in the morning, and the second at 9:26 in the evening.
So it is not yet too late to begin preparing for the momentous events. But do not delay! These precious minutes will never come around again!
Every once in a while an AC says something salient. Case in point:
the spying was on the committee who are supposed to oversee and authorize the spies. The committee can hardly effectively oversee the spying when they are turned into a target of spying themselves.
It seems like Feinstein has adequately demonstrated that she is incapable of doing her current Senate assignments. Is there a procedure to force her out of her chairmanship for cause, where cause is obvious incompetence?
Can a Senator like Feinstein be impeached?
Some people cuss a lot. Others swear. Some use foul language.
But some are just potty-mouthed. Their attempts to sound tough are just so infantile.
I've always felt that "potty-mouthed, chair-throwing, murder-threatening, monkey dancer" was an adequate moniker.
The sensible thing to do would be to migrate to a Linux distro with good business support, and install WinXP on VMs within that Linux. That's as secure and future proof as you can get.
It is impossible to get any hard data on Linux usage. It is completely unpossible to get any hard data on the number of WinXP installations that are running along side or within a Linux distro. Anecdotal information is as good as it gets.
I bother to participate in these discussions because I'm an old curmudgeon who thinks the world would be a better place if all the marketeers were slapped upside the head until they barfed out their intrinsic idiocy where everyone could see it. I much prefer to live in a society where people are using good computer systems to build their neighborhood associations, clubs, church groups, and so on, than to see them waste all that time and money on a bunch of Microsoft or Apple crap that costs too much and often gets in the way of doing the actual work.
My anecdotal information is from my experiences setting up and using Windows systems since day one (I started installing and managing early DOS networks in the 1980s), and using Linux distros as soon as they became effective, around 2000 - 2003. I stay in touch with Windows developments, and I actively follow several forums, etc, in the Ubuntu universe.
You are focused on a dwindling minority of the market and not looking at the larger picture.
Try talking to Linux distro users. Most have either set up dual boot systems with some kind of Windows in one of the partitions, or are running virtual machines inside Linux, with one of them being a Windows version, or are thinking through which of these they should do. Mostly WinXP is used for these secondary OSs. It is stable, it is easily available, and when run as a secondary OS its vulnerabilities don't matter so much.
At this point, the numbers of Linux users who also have WinXP installed is comparable in size to the number of ancient WinXP only machines that are being used by little old grannies.
Upgrading an ancient version of Ubuntu to current status would be a serial process: you could not do it directly but if you wanted to, you could upgrade through the intermediate releases until you were current: 4.10 to 5.04 to 6.06 (1st LTS) to 8.04 (LTS) to 10.4 (LTS) to 12.04 (latest LTS). The next Long Term Support version is in beta now and will be released as 14.04 next month. I'd skip 13.10: either wait for 14.04 final or install 14.04 beta, which is pretty stable from what I hear.
However the easier way would be to back up
The process is much easier than upgrading from any version of Windows to any newer version of Windows. I think Microsoft is still purposefully breaking upgrades. The only ones I have ever done that were mostly seamless was from Win3.0 to Win3.1 to Win3.11. Going from Win3.11 to Win98 was not too bad, either (I skipped the horrible Win95 crap).
I expect a lot of the machines that are still running WinXP are dual booting with one of the newer Linux distros. WinXP is still the greatest for legacy apps and good enough for many of the classic games. Everyday work can be done more easily and safely in a Linux distro.
RTFA. Bugatti hid the plane before the Germans invaded. If they had found it, and made use of the technology Bugatti had developed, the Germans would probably have succeeded in their attacks on London.
