You saw off the bottoms of liter soda bottles and insert the remaining neck in a board, which is then placed "big side out" in a window.
With the wider part facing outside, hot air is drawn into the funnel created. Air pressure changes as the air passes through the neck into the room and cooled air is released. This can cool a room by five degrees Celsius in a short amount of time.
Maybe this wouldn't be "cool" in Phoenix, but it sure makes a difference in some countries where electricity is not available or is on and off.

Thousands of birds, fish, and turtles ingest plastic waste that ends up in the ocean by the thousands of tons.
Now, Saltwater Brewery in Delray Beach, FL, has invented a biodegradable six-pack ring that can be EATEN by animals or even humans.
No poisonous after effects, no years-long entrapment.
The rings are made of wheat and barley byproducts of the beer brewing process. They are also compostable on land.
Hungry? People can even eat them--although they are not really a gourmet snack.
Since the rings are more expensive than the plastic ones, the inventors are hoping demand will increase and other brewers will use these, and thus the positive impact will justify the cost.
Hear that, Budweiser? The ocean you save may be ours.

They say eventually this will be useful as building material and in light-based electronics.
Basically, they removed the molecule called lignin, which makes wood rigid and dark in color. This left the colorless cellulose structures--which they then filled with epoxy.
You can check out the journal Advanced Materials for more details.
The results were a "wood" that is mostly see-thru and has a high haze (scattering light), which makes it comfortable to look at.
This material could help solar cells trap light. The light would come in because it was transparent, but the high haze would keep the light bouncing around until it was absorbed by the solar panel.
Right now, the blocks of wood they are working with are 4 inches wide--but they say the process is scalable.
They are looking at five years to getting this to the market for use.
Solid wood windows...what will they think up next? Stay tuned.

For that, you need a special light--such as an X-ray light with a wavelength as small as an atom, pulsing at the rate of femtoseconds. A femtosecond is to s second what a second is to 32 million years. In other words--fast.
Six years ago, the Dept of Energy's SLAC National Accelerator Lab answered the call of the scientific community and built an X-ray-free electronic laser--the XFEL.
Since 2009, this powerful "microscope" has generated molecular "movies," gotten a glimpse of a chemical bond, traced electrons moving through materials, and made 3-D pictures of proteins leading to drug discoveries.
Such machines have now proliferated all over the world. Check out the March issue of Reviews of Modern Physics for an overview of the first five years of progress.
Some high spots:
Next-gen computers and the power grid. The Linac Coherent Light Source or LCLS, as it's called, is homing in on new computer components surpassing old limits on what computers can do.
Better, cleaner fuels and chemicals. Using this technology, scientists can now measure never-seen-before steps in chemical reactions, helping them design better fuels, fertilizers and industrial chemicals.
More effective meds with fewer side effects. Half of all medications on the market target receptor proteins on the outer layers of cells--we can now see how the meds dock on the cells. The LCLS technology allows smaller crystals to be examined as well as crystals too easily damaged by conventional X-rays.
Renewable energy that mimics nature. LCLS has allowed us to see how plants use energy from sunlight (photosynthesis), It can measure steps in the process not seen before.
Fusion reactions and seeing inside planets. High-power laser systems heat matter to millions of degrees and crush it with billions of tons of pressure. This allows scientists to see test resilience of materials and to see conditions as they might be at the heart of planets, which may lead to learning how solar systems form.
Located in Menlo Park, Calif, the DOE's SLAC lab attracts hundreds of scientists from around the globe.
This is an example of a US Govt basic research "challenge" that will be worth every penny spent.

The films feature female athletes--showing how they bring their own definitions of creativity to sports.
<--- EXAMPLE: French runner Julie Aubert. https://youtu.be/244vlGAQGbY. At 24, Julie began running through the streets of Paris, eventually getting her friends in on it. She created Mademoiselle Run, a digital tribe for women into running.
EXAMPLE: US Soccer star Morgan Brian. https://youtu-be/OTNbVxh-FZM. Morgan was essential to the US Women's Soccer Team's 2015 World Cup Victory. She's young--22--and doesn't let being on the stage with the top players get to her..she just has fun.
EXAMPLE: Brazilian volleyball champ Jaqueline Carvalho. https//youtu.be/mfF-bYmMoEU. Jaqueline led her team to double Oly gold in 2008 and 2012. She plays with reckless abandon, which has resulted in countless injuries and long periods of rehab.
EXAMPLE: Skater Julia Lipnitskaya. https://youtu.be/EDJHt79YUE8. In 2014, Julia led Team Russia to the top in the Sochi Olympics, making her the youngest Russian Gold Medal winner ever. She is still just 17.
"I'm Here to Create" airs in more than 50 countries and will be seen at the Oscars, as it was at the GRAMMYs.
Putting it all together in sports may not be what first comes to mind in terms of creativity, but it does require creative drive and talent.

Or is it really creativity? Sometimes I see stories and programs dubbed with the Creativity description just because they are different than what the organization did before...so they got "creative."
People jump "out of the box," "get told to stay in the box," "make a new kind of box," or think up weird whimsical products that really address no real need or impulse. Examples: A gizmo to give the bike lane a green light faster when it rains...or a little rocker you can stand on at your standing desk...Both of these sound dangerous. How about those flaming Hoverboards, too?
Creativity--to me, anyhow--means conjuring something out of nothing, or destroying something harmful and putting something helpful in its place. Or maybe something just intriguing or beautiful.
The Apple watch--people had a watch to tell time. They had a phone to access the internet. The buttons were teeny...Not a huge seller...
All this wearable technology...Do you want your clothes buzzing you or bossing you around?
I saw a device the other day that will analyze what you put in a cup...The cup does it. Someone said, "So you're holding a beer, you put it in the cup and it says, 'This is beer'? So what."
So as we drag ourselves into the largely random world of news and discoveries and inventions to start another year...We need to look for the truly creative. The truly new. Or the truly new way of doing something truly old.

|Watermelons with white inner |
rinds (top--lower right)?
He and his students in his World Vegetable Crops class go a a nearby museum to look a Renaissance still lifes to see how carious aspects of plants have been bred in or out over the centuries.
With grains, he says, archeologists can look at actual samples--but the more moist plants don't last.
He calls fruits and vegetables "art you can eat."
Hmmm...What else could we tell from paintings? Maybe that people are taller now. Breeds of dogs we don't have now? Certainly trends in fashion. Weapons?
