Wearable A/C


The gringa considers nudity to be part of the climate change solution. It could solve lots of problems:

  • Conserve water.
  • Reduce emissions with less marketable goods requiring shipping.
  • Reduce energy usage to cool homes in warm climates.

However, some innovators in the fashion industry may have come up with a cool, pardon the pun, solution that will allow everyone to keep themselves covered and still be comfortable despite the heat.

With the invention of plastic based textiles, cooling is all part of the design of a new, innovative fabric that engineers have developed at Stanford University. Combining the disciplines of chemistry, nanotechnology and photonics with an old-fashioned cotton fabric, sweat and body heat pass right through.

Believe it or not, current “breathable” fabrics are simply not breathable at all. People get hot wearing clothes because invisible waves of infrared radiation produced by our bodies are trapped under the clothes we wear. In research studies comparing standard cotton with the new fabric, scientists discovered that good, ol’ “breathable” cotton raised the temperature of skin surface by nearly 4 degrees Fahrenheit (or 2 degrees Celsius). For the gringa, that would make all the difference in the world. I could keep my A/C off and my family clothed in cooling fabrics.

The gringa only sees one problem, the plastic connection. Plastic is, of course, a petroleum based product. Isn’t dependence on petroleum the bane of human existence? Isn’t it at the heart of climate change? Is it not the object of war for profit? So has the science community really come up with a practical solution to help contribute one tiny bit to the climate change solution or has it simply opened a Pandora’s Box for the future of petroleum wars? Will nations continue to slaughter one another in order to control oil fields that will be necessary to keep people clothed in fabrics that will help them survive the catastrophic heatwaves of the future?

Maaahhhvelous MAVEN!


Yesterday was an important anniversary at NASA. Celebrations were in order to mark a successful year of the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft orbiting the Red Planet fulfilling its mission of understanding the upper and lower atmospheres of Mars. Scientists want to know how Martian atmospheric gases that escape into space change the climate of the planet. The ultimate question is whether or not the pattern of atmospheric evolution can trace back to an ancient history where life could once have been supported there.

MAVEN inserted itself into a Mars orbit in September, 2014 and had a dangerous encounter with Comet Siding Spring within its first month in action. Over the past twelve months, MAVEN has carried out and recorded atmospheric observations for ten of those months.

It has detected a pattern of particles at both poles that create a “Mohawk” effect as they escape the atmosphere in plumes. Mars also has a metallic particle layer high in the atmosphere which lights up when affected by solar storms. These particles are leftovers from space rubbish left behind by comets and meteorites. The gringa thinks Mars would be the perfect place for some rock-n-roll concerts.

The violent atmosphere of Mars is punctuated by solar and space radiation, magnetically and electrically charged solar flares and Coronal Mass Ejections that strip the upper atmosphere of Mars of electrically and magnetically charged ions. The data collected on MAVEN can be analyzed to hopefully answer the question if this is the reason for atmospheric loss on the Red Planet and if so, scientists will then attempt to establish a time frame for the continued erosion of the Martian atmosphere.

NASA is very proud of the teamwork that has produced such a successful Martian mission as the MAVEN project. Engineers designed and built a sturdy spaceship that remains in excellent working order despite the extreme conditions it functions within. Although mission completion date is only months away, it is expected that the mission will be extended. The rich amount of data for a hungry science community is too valuable to give up as long as MAVEN is still operational. NASA will be giving the green light for this little workhorse to stay on the job at least one more year.
