Test Firing: 3D-Printed Rocket Injector

NASA has successfully tested its first rocket engine component made through 3D printing. On Thursday, NASA subjected its new rocket engine injector to a series of high-pressure fire tests involving liquid oxygen and gaseous hydrogen, demonstrating that additive manufacturing (its official name) could one day help the agency build the next generation of rockets faster and at lower cost.

Additive manufacturing uses layers of metallic powder traced in specific patterns by lasers. The technique isn’t too far removed from traditional 3D printing, except it uses high-powered laser beams. While an engine injector is normally one of the most expensive components of a rocket engine to produce, additive manufacturing not only reduces development time from over a year to a number of months, it also cuts costs by more than 70 percent. Following the successful test, NASA says it will look to scale-up and establish production requirements for the injector, helping it “demonstrate the feasibility of developing full-size, additively manufactured parts.” However, the agency says has no plans to test its printed components in a live test flight until 2017.

Vegan? Watch Your Protein Levels.

If you are a vegan or vegetarian with a secret stash of candy, jelly beans or dark chocolate, join the club. A constant craving for carbs with occasional headaches, muscle or joint pain may be due to a slight deficiency of protein.

The symptoms of a severe protein deficiency include:

  • Edema (swelling)
  • Thinning brittle hair and/or hair loss
  • Ridges in finger and toe nails
  • Skin rashes; dry skin
  • Weakness
  • Constant Fatigue
  • Muscle soreness and cramps
  • Slow healing
  • Skin ulcers
  • Sleep issues
  • Frequent headache
  • Nausea
  • Fainting
  • Depression/anxiety

Sooo, what can we do to reverse this condition? Carnivores and omnivores simply chow down on anything that moves. Vegans and vegetarians have a slightly more complicated problem, but one that’s nonetheless manageable. Here’s a list of protein sources found in Kingdom Plantae:

  • Seeds, sprouted
  • Nuts
  • Beans
  • Lentils
  • Whole grains (in order from highest to lowest protein content): Wheat, amaranth, oats, rye, triticale, teff, spelt, wild rice, barley, buckwheat, quinoa, millet, sorghum, corn, rice.
  • Soy
  • Peas
  • Peanuts
  • Spinach
  • Potato
  • Sweet potato
  • Algae
  • Seaweed

Crossing the U.S. on Ten Gallons?

URBEE is a return to fundamentals, a rethink of traditional automotive design and manufacturing. As a species endangered by our own actions, we must quickly learn to stop burning fossil fuels. Surely, the ultimate goal of Design is to serve the ‘public good’. Therefore, corporations and individual designers have a responsibility to offer products that are not only useful, but in balance with the environment.

URBEE is now crowd-funded to create the greenest car on Earth. A first prototype was completed in 2013. It became the first car to have its body 3D printed. The team recently initiated a second prototype, called URBEE 2. They are embracing Digital Manufacturing as essential to the design of an environmental car. Engineered to safely mingle with traffic, the two passenger vehicle will have its entire exterior and interior 3D printed.

James Turrell at the Guggenheim

Turrell at Guggenheim
To work with the light itself, to create experiences for visitors is probably the greatest thing anyone who works with light can do.
The exhibit opens with a bang. This treatment of Guggenheim’s iconic atrium is nothing short of stunning. By re-imagining the atrium as a volume on which to paint with light, Turrell makes a simple statement of overwhelming power.
The shot to the right shows the atrium in green but over the course of minutes it will change colors very slowly crossfading through simple pastels and vibrant punches of red and purple and blue. You are invited to sit back and tilt your head up and just experience this expanse as your ears are filled with the conversations and murmurs of other visitors. It’s the light itself and it’s relationship to space that Turrell works with and in this case to stunning overall effect.

Know Your Food Containers

Understanding different types of plastics is crucial when making decisions on items for your family and home. Recycling numbers, ranging 1 through 7, are used to specify what type of plastic is contained in an item and in turn how that item may be recycled. They are found inside an M.C. Escher style triangle of arrows turned in on themselves on the bottom of most plastic containers. Of the seven different types of plastic available on the American market, all are based on a different resin. Each of these seven varies in both its effect on environmental safety and ease of recycling. What follows is a general outline of most types of plastics along with their most common uses.

PLASTIC #1: POLYETHYLENE TEREPHTHALATE (PET OR PETE)
Common uses: 2 liter soda bottles, single use water bottle containers, cooking oil bottles, peanut butter jars.
This is the most widely recycled plastic. Commonly recycled, PET is semi-rigid and very lightweight. It’s best suited for single-use containers as it can break down when exposed to light and heat, causing it to leach. PET can also be recycled into fabric, similar in strength and appearance to virgin nylon.

PLASTIC #2: HIGH DENSITY POLYETHYLENE (HDPE)
Common uses: detergent bottles, milk jugs.
HDPE is a sturdy and reliable non-leaching translucent plastic. HDPE resists UV penetration, which can damage and discolor the plastic. Dishwasher-safe and able to withstand temperatures from -148 to 176° F (-100 to 80° C), it’s ideal for food and beverage storage.

PLASTIC #3: POLYVINYL CHLORIDE (PVC)
Common uses: plastic pipes, outdoor furniture, shrink wrap, water bottles, salad dressing and liquid detergent containers.
Most PVC vinyl products contain phthalates, which mimic human hormones and also affect various life forms including fish and invertebrates adversely. For this reason, we do not recommend products made from PVC for food storage.

PLASTIC #4: LOW DENSITY POLYETHYLENE (LDPE)
Common uses: dry cleaning bags, produce bags, trash can liners, food storage containers.
LDPE are safe, non-leaching plastics. Flexible, impact-resistant and microwave-proof, it’s dishwasher-safe and able to withstand temperatures from -148 to 176° F (-100 to 80° C). Safe for use with food and beverages.

PLASTIC #5: POLYPROPYLENE (PP)
Common uses: bottle caps, food containers, drinking straws.
BPA-free, polypropylene is commonly used for injection molding. It’s resistance to high heat generally makes it microwave and dishwasher safe, as well as a good option for food and beverage storage.

PLASTIC #6: POLYSTYRENE (PS)
Common uses: packaging pellets or “Styrofoam peanuts,” cups, plastic tableware, meat trays, to-go “clam shell” containers.
Polystyrene foam is a major component of plastic debris in the ocean, where it becomes toxic to marine life. Currently, the majority of polystyrene products are not recycled. This material should be avoided.

PLASTIC #7: OTHER
Common uses: LEXAN, certain kinds of food containers and Tupperware.
This plastic category includes any plastic other than the above named types. These containers can be any of the several different types of plastic polymers.
Polycarbonate is the most commonly-known #7 plastic. Proven to leach BPA, it is not recommended for food storage. Not all “other” plastic is polycarbonate, however. Plastics labeled #7 can also be a combination of several safe plastics. You should engage in due-diligence when making decisions about #7 plastics.
