Question I would value you your opinion on this product, the Enviro Loo. www.swsloo.com
Thanks,

Answer Interesting technology.
It appears that the thing making it work is the tall stack and the rotating ventillator cap on the surface which draws air in and helps the solids dewater.
I would guess that it is not totally odor free, however, because the stack is raised above your nose level, and there will be some odors, but like lots of other things, if you are drying something quickly enough after a time it does not smell much. I would not necessarily recommend this for an in-house installation however, unless you put the stack through the roof and vent it well to outside.
It is innovative and may be a good temporary solution for certain locations because as humans we produce only a few liters of urine per day, and a few grams of solid fecal material per day. So, it looks good.
Good luck, let me know what you decide to do with it. I must comment before I leave that it is not maintenance free as some of the other units on the market are. The typical out house goes a number of years without any maintenance, and you may find that you have to be careful when you remove the screen as it may present a special disposal problem because it has a fecal origin. it will not be bacteria free nor suitable for fertilizer. you may want to contact the manufacturer and find out what and how to dispose of the screenings and the liquids when it gets full. I suspect that I know, but I'll let you find out for yourself.
good luck.
