I looked into international laws regarding vehicle sizing. The best I could find was UN Convention on Road Traffic from 1949. Following its rules should allow movement in the 97 countries that signed it except for Switzerland that did not ratify it. There is at least one rule that goes against...

I'm talking volume. It's not big, but whether it's efficient depends heavily on usage pattern. Here I calculated that for the volume of the best pannels I could find, one would be able to camp with diesel fuel for nearly 9 days. Good when you spend a lot of time in a single place, bad otherwise...

How about wind power? The first turbine specs that I found: http://primuswindpower.com/wind-power-products/air-breeze-turbine/ Sample wind map 80 meters above the ground: http://apps2.eere.energy.gov/wind/windexchange/pdfs/wind_maps/us_windmap_80meters.pdf Good majority of is above 4.5 m/s. The...

59 W/kg, 86 W/l, 145.9 W/m^2 Diesel has 9.94 kWh/l, after generation that's 2.98. Solar of equivalent volume needs 8 days and 16 hours to generate so much. If I make no mistake, I don't see a good justification for solar in a vehicle that needs to have a generator anyway. At least as long as...

Summary of claimed power consumption of incinerating toilets, electric or diesel: Ecojohn uses 0.3 l of diesel for waste incineration which equals to 3 kWh and 0.113 l for urine (1.13 kWh). Incinolet uses 1.5-2 kWh of electricity. Cinderella - 0.8-1.5 kWh Usenburn uses 0.076 l of diesel (0.75...

I added another few water makers to the list at http://www.expeditionportal.com/forum/threads/124789-Fully-Integrated-MAN-or-TATRA-6x6-or-8x8-Expedition-RV-w-Rigid-Torsion-Free-Frame?p=1859975#post1859975 I'd like to point out some of the most interesting ones, judging just by numbers: 1...

I made a compilation of specs of various water makers based on Bio's list of producers: http://www.spectrawatermakers.com/documents/Ventura%20150-200T%20Specifications.pdf RO, 27.2 kg, 30 l/h, 4.5 Wh/l http://skwatermakers.net/wp-content/uploads/2012/11/DB_Manual.pdf...

So it's not like you can filter the same over and over; instead the water recovery ratio is the thing that varies. Understood.

After single cycle, waste water is concentrated by 10%. I don't believe marine RO would fail after 10% increase in salt content. https://en.wikipedia.org/wiki/Seawater#Salinity says: That's 20% already. Overall, your waste content increases with each cycle, just like you say. One can't sustain...

Great thread. Some thoughts: 1. Height-adjusting suspension can provide extra vehicle volume. You don't have to meet legal height limits with the suspension lifted to the offroad height. Keeping it just high enough for the road at 4m will give you several extra square meters of space and lower...
