The Future Of Water Purification

water-purificationScientists at Stanford have developed a fast, water disinfecting device using nanofilms and visible light. It is relatively small, but could have a big impact on both hikers and boondockers.
The glass tablet is topped with bits of copper and “nanoflakes” of the industrial lubricant molybdenum disulfide.

“UV light only counts for 4 percent of the total solar energy. If you can also use visible light, that’s 50 percent of solar energy.”

The early results show highly efficient water disinfection against E.coli and a lactic acid bacteria. Viruses and harmful chemicals may follow. The water should not be cloudy.
It could be commercialized in 3-5 years.

Front Parking Sensor

Removal of the front bumper is the biggest drawback while installing this parking aide. The previously installed backup parking sensor, had a quickly removable rear bumper; the front bumper involves dozens of screws, bolts, clips and clasps.

The firewall is another unexpected hassle, together with the power source and switch location. The backup parking is only activated when the van is in reverse, while the sensor in the front needs a manual on/off switch. The 12V power can be drawn from a number of different sources, all in close proximity of the switch.

I did it all in about six hours, but with an extra set of hands you can finish this project much faster.

As always, I have detailed every step on the Project’s Page, and added lots of pictures, a video and a project guide, free for you to download.

A New All-Electric Tesla Cargo Van

Tesla Motors cargo vanA new all-electric Tesla cargo van is unlikely to be produced for many years, but the likelihood was first mentioned when CEO Elon Musk recently discussed his future plans with the company.
The electric van could be built on the truck chassis, used for the pickup truck that may hit the market next year.

Tesla Motors has never committed itself to an electric cargo van, yet it would make sense as it could feature electric outlets for power tools powered by the vehicle’s battery pack. For RV’ers, an integrated battery bank with optimized charging capabilities could be the real nirvana.

Today’s Snapshot

first board
hardboard-templateAfter a lot of measuring and making a template for the window frame behind the Murphy bed, the actual work started on the frame. I chose hard maple as the whitish color of the wood, complements the white Formica on the walls. The frame has no 90 degree corners and is hand-made according to the template. Ultimately, it will be firmly attached to the van’s metal wall and will support the large wall panel around it.

Plywood Sub-Floor Installation

It was time for the plywood to be added to the Poly-Iso insulation panels on the floor of the cargo van. I use the paper templates that I made previously to remove the cut-outs from the sheets of plywood and add dadoes to form an interlocking system.

Although I ended up sealing the plywood at a later stage, this is the time to get your Shellac, varnish or polyurethane and a couple of brushes and protect the plywood against moisture.

As always, I have detailed every step on the Project’s Page, and added lots of pictures and videos.

Spray Foam Floor Insulation

Laying a sub-floor in an RV consists of many individual steps. After removing the tie-downs, insulating the wheel wells, creating plywood templates, cutting and gluing the strips of Poly-Iso to the floor, I’m now completing the insulation by filling the voids with a spray foam application.

Although it is a closed-cell, waterproof foam, after cutting off the excess, what remains is susceptible to moisture, but still adds insulation and some structural cohesion to the floor.

As always, I have detailed every step on the Project’s Page, and added lots of pictures and a video.

Keeping Your RV Cool With A Hidden Floor Vent

Temperature, ventilation and condensation are some of the issues that complicates RV living. But keeping the vehicle cool and free from humidity and condensation may be addressed by installing a floor vent.

A floor vent in combination with a standard roof vent, should produce enough natural convection, that the airflow could sustain itself. By placing one vent at the bottom and the other at the opposite end in the roof of the vehicle, some of the conditions are created for a sustained convection airflow. A basic example is when warm air rises. For convection to happen, distance between the vents, a height difference and a temperature difference all play a role.

Insulate Your RV Floor – Part Four

Gluing Insulation

Every RV should have Insulation and gluing it is the best way to keep it in place. As part of the Insulated Floor Project, I just finished gluing all the individual pieces of Poly-Iso insulation board between the floor ribs of the Ford Transit floor.

You can read about all the details, and view all the photos and videos on the project page. When the entire floor project has finished, the complete guide will be made available for download.

Your comments are appreciated. Tell us about your RV mods and how you did it, and we might publish your story.
