Keeping Cool – window films

Colleen applies vinyl film to the exterior of a window.

Interior and Exterior Films
We are all familiar with window films (sometimes referred to as tint with automobiles). Modern films are designed to block UV light that damages plastic, cloth, and furniture; optical light (what we can see) to reduce glare; and infrared (what we can feel) to reduce total thermal transmission from the sun into our homes or cars. It’s all light, just shorter and longer wavelengths (yes, you learned this in high school, but probably forgot :).

Most films are applied to the interior of glass windows, or at the factory to the interior of the first pane of glass in a double-pane insulated window. The films are rated for transmission as a percentage, i.e. “75% optical transmission” means the film blocks 25% of the in-bound light we can see, and allows 75% to pass through. Most block 99% of UV and upwards of 90% IR.

In a casual study I conducted at my place of work, I noticed that non-treated glass remains relatively cool to the touch (ambient room temperature) as full spectrum sunlight enters the room and heat the objects it strikes. When an interior window film is applied, yes, the objects in the room remain cooler, but the glass itself heats up. If the glass is heating, that means it is generating heat energy, or infrared light, and is in fact heating the room, even if to a lesser degree (50% in / 50% out). This deserves further study, to learn how much the glass is heated through the process of reflecting IR with an interior film, and how much heat energy ends up in the room anyway.

That said, if you apply a film on the outside of the glass window the heat energy is reflected without heating the glass, and as such is more effectively keeping the interior space cool. But most translucent films are not intended to be applied on the exterior as they will dry-out, get scratched, and fall off prematurely.

There is an alternative …

Temperature differences by Kai Staats and Colleen Cooley

Save a bird. Reduce your electric bill too.
We live in the San Pedro River valley where more than 300 species of migratory birds travel twice each year. And year-round we enjoy a local population of doves, finches, woodpeckers, humming birds, ravens, hawks, and many more. Sadly, they too often see the reflection of the blue sky in the early or evening hours and fly into our windows, either stunned for a few minutes or breaking their necks.

We tried curtains on the inside, and hand-cut paper snowflakes taped to the windows too. We successfully hung shade cloth in front of two windows, but this solution is not feasible all around for a variety of reasons, including the amount of structural modification and resulting loss of visibility.

Then we discovered the not-for-profit company CollideEscape whose various exterior window films provide up to 100% guaranteed elimination of bird collisions. This vinyl film is the same as that applied to city buses, painted-on advertisements making the windows appear opaque on the outside when in fact the passengers can see just fine.

We applied these to all upper windows. It worked perfectly. Not a single bird collision on those windows with the film. In the process we also discovered that the film drastically reduces the interior temperature where sunlight falls, by as much as 30F. This was initially noticed by sitting in our loft to determine how our view was changed, inside-to-out.

With two windows side by side, in the same morning light, one had the vinyl film, the other did not. The temperature difference was immediately noticeable on our faces and forearms, and confirmed with a mercury thermometer placed in the light of each window. We have since covered all our basement windows too and noticed a significant change in the temperature of the carpet where the sunlight falls. An infrared thermometer noted the temperature of the carpet (yes, carpet does get hot) dropping from 107F in direct sunlight to 85F behind a glass pane covered with the CollidEscape film, the lower temperature just seven degrees over the 78F room temperature (as measured on the carpet beyond the sunlight of any windows) at that time. Our basement is noticeable cooler than the last few years, which aids in cooling the entire house.

First crew enters SAM

Arizona television station KGUN covers the first team entering SAM at Biosphere 2

Today the very first visiting research crew entered SAM. Five years and five months from concept to design, fund raising, construction, the Space Analog for the Moon and Mars (SAM) is now operational. This represents the single largest project I have ever undertaken, and the most diverse, creative, diligent team I have ever employed. We have built the world’s only operating, hermetically sealed and pressurized other-world habitat analog. This is something for which I am truly proud (and totally exhausted).

Inclusion I was welcomed by three television crews, two radio crews, Linda Leigh of the original Biosphere 2 mission, Executive Director of Biosphere 2 Joaquin Ruiz, Deputy Director of B2 John Adams, and more than 60 persons watching the first closure of this unique hermetically sealed, pressurized habitat. Interviews commenced at 5:00 AM and continued until 10:00 AM when one by one, Cassandra Klox, Eiman Jahangir, Bailey Burns, and Sheri Wells-Jensen entered SAM carrying their personal bins.

The walking water bottle

I was at my car, loading for a trip to town, when I set my half-full water bottle on the hood. I reached into my pocket to grab my keys, my arms full, when I heard the bottle vibrating. My car was not running, rather sitting perfectly still. When I saw what was happening, I set everything down and grabbed my phone to record.

It appears the inherent motion of the water coupled with the rounded bottom edges of the bottle, concave surface of that portion of the Subaru hood, and half full water enabled that trapped kenetic energy to translate into motion. What’s astounding is how the dual-cycle standing waves in the water (meaning, the waves repeatedly return to the same position and height, amplifying the motion) “walk” the bottle down the car’s hood. The motion of the water in the bottle is essentially in equilibrium, the waves casting their energy against the inside of the bottle balanced by the forward “walking” motion invoked by the pull of gravity over an ever-so-slightly sloped surface.

But when that surface changes, the system is imbalanced, the bottle is no longer stable, and topples over the side.

I reset the bottle at the top and without any effort on my behalf, it did it all over again. So much fun!

My former high school physics professor Dan Heim found this worthy of investigation and included a full explanation as the topic for his weekly science essays at Sky Lights.

Space Radio with Dr. Paul Sutter

Astrophysicist Dr. Paul Sutter interviews SAM Director Kai Staats from within the Biosphere 2!

“This week on Space Radio I had the opportunity to catch up with my good friend Kai Staats. Kai joined us from the grounds of the University of Arizona’s Biosphere 2 as we talked about his newest project, Space Analog for the Moon and Mars. Among other topics, we discussed the removal of perchlorates from the Martian soil and how Methane could potentially be used.” — Dr. Sutter

The construction of SAM begins!

SAM at B2 with Trent Tresch and Kai Staats

After two and a half years in research and development, networking and team building, chasing dollars and fund raising, this is the day we can officially say, “SAM IS BEING BUILT!”

SAM is a hi-fidelity, hermetically sealed analog and research center composed of a crew quarters, airlock and hub, and greenhouse with temperature, humidity, and carbon dioxide level controls. When complete, SAM will include a half-acre Mars yard for pressure suit, tool use, and rover tests. Located at the world renowned Biosphere 2 outside of Oracle, Arizona SAM is built around the original Test Module, a 480 cubic meter sealed greenhouse with automated, gravity-fed pressure regulation system designed and built by Taber MacCallum, William Dempster, and fellow Biospherians in 1987.

This week I have moved from my residence in Cascabel, Arizona to the Biosphere 2 where I fully anticipate long, back-to-back days of physical labor and further development of this exciting program. It is likely that my own blog entries will be few and far between for the coming year, but I will be posting regular updates about our progress at samb2.space/blog/.

I hope to see you there!

COVID-19 isolation as an analog for space travel

As one who has frequently lived in isolation, in 2013 on a remote ranch in Colorado six weeks without seeing another human, and now in a wilderness abode with the closest neighbor a quarter mile away, the nearest town more than thirty, I recognize that my situation is the opposite from those living in isolation in the city.

This disparity causes me to wonder, Would be more difficult to venture to Mars with crew mates, or totally alone? Living in a highly confined space for more than a half year is certainly one of humanity’s greatest challenges, while the practices of living alone, solo trekking, and meditation retreats are celebrated as a means to elevate the human experience.

Do we also celebrate interpersonal caring, space sharing, and communication in such a way as to uphold those who have “survived” group dynamics in close proximity for extended periods of time? Are there monks who practice daily banter rather than go months without speaking?

Perhaps the original Biosphere 2 was just such an experiment, in the end. Many lessons learned. Surely, every Apollo mission had stories to tell as does every U.S. Navy submarine captain.

In this home-bound arena many people are learning what it means to share a small space with others, or how to go it alone. What we can learn from this experience as we design and construct prototypes for off-world habitation? How can our space program benefit from what are now learning? What does personal space mean, when space is already limited? How can we train individuals to communicate in such a way as to uphold the communal space and respect personal space too? How do you assure astronauts will come out the other end of a long journey bound by the mission objectives and also bound by something even more powerful, friendship for a lifetime? And is over militar training the only way? How does architecture support or undermine interpersonal relationships?

Questions without immediate answers … we will see.

True or False … stay tuned

There was a period in my life, from 2012-2015 when I was adept at producing a regular series of essays. I was weekly sharing stories of my travels, adventures, meetings, and interactions with the world in so many ways. I felt, at that time, that my life was rich, dynamic, and impossibly full. Yet, now, I am working more hours each day, more full days each week than in the past decade and the richness of my engagements is equally fulfilling, even if in a different way. Yet, the stories are internalized, always on hold, for the process is each day unfolding.

When a day in Palestine, Tanzania, or South Africa is a day worth describing, a day working on Python coding leaves one wanting to get away from the keyboard, not closing the day with more typing. What’s more, there is a fear of ridicule for sharing the process if the process is one already tested and proved true or false, for in research the goal is not to rediscover, but to discover anew.

To share the process is to share potential success or potential failure in the making. And that is hard to do.
