Grab bag of links

Been thumbing through Alexander's pdf book and found some useful links.  Not all of them are current and not all of them have good customer reviews.  However, I did find some good reviews for the following items:

• RTS Home Accents 50-Gallon Rain Water Collection Barrel with Brass Spigot, Brown
• WaterWorker HT20HB Horizontal Pressure Well Tank, 20-Gallon Capacity, Blue
• Nature's Head Dry Composting Toilet / Standard Crank Handle
• - Northern Industrial Easy-to-Assemble Utility Trailer Kit - 40in. x 48in
• - Ironton Heavy-Duty Trailer Kit - 5Ft. x 8Ft., 5.30-12in. Tires
• one more I just found  :   Fresnel lenses by Greenpowerscience

This one should be linked to the prior one ( or in this case two because that one is linked also) in order to keep a series of like minded posts.

I bought a passive solar water heater today.  Not that much, about 50 bucks.  I'll use it in combination with my freezer and a water pump plus transmission cooler in order to passively heat/cool my trailer.

If you didn't notice, there was yet another trailer link in there.  This time for a 5x8, and this one looks like the best one yet.  A slight modification to the 5x8 concept D floor plan, and we could be in business.

Update:

Sewage treatment system.
