I'm a mother of three, with an aeronautical engineering degree.  Although it's been a while since I've done any aircraft design, there are surprising applications of

The Eurocopter BO-105 CBS 4 twin engine helicopter with a Rigid Rotor system can do some amazing aerobatics. Stock model with a Rigid Rotor system, the fixed rotor is why it can do aerobatics.

These pictures are actually a couple months old, but I just saw them for the first time. They are pretty amazing, and even more so when you realize that no one got killed. "Etihad was to receive their next A340 this week, but it seems that delivery may be delayed. While running an engine test at the Airbus facility in Toulouse, France, the A340-600 jumped the chocks and headed for the blast wall. The good news is the blast wall held up remarkably well. The bad news is the Airbus did not."

Baking soda is one of those wonder substances with useful applications far beyond simple baked goods. Baking Soda We all know we can open a box and leave it in our fridge to combat odors. But as a result of innovative work done by Skyonic Corporation in Texas, baking soda may become one of our greatest weapons against carbon emissions and global warming as well.

Skyonic has developed a “post-combustion carbon capture and sequestration technology that works with any large-scale stationary CO2 emitter” (e.g.- coal, natural gas or oil fired power plant). The process removes heavy metals, acid gasses, and carbon dioxide from conditioned at-temperature flue gas. The carbon emissions are then stored as stable sodium bicarbonate (better-than-food-grade baking soda) for long-term storage as land or mine fill. The clean flue gas is then returned to the plants stack for release.

Christmas trees are appearing in homes throughout the country and families prepare for the holiday season. But in this age when we are all asked to be aware of the impact we are having on the environment, is the right choice to purchase an artificial tree and use it year after year, or go in search of the perfect living tree to be the centerpiece of our holiday decorating?

The answer may surprise you.

Christmas Tree

So the kids fell asleep late last night after finally crashing from their Halloween sugar high. There are smashed pumpkins out on the street, toilet paper in the trees, and still 3 to 5 pounds of candy remaining per child. The pumpkins and toilet paper can be cleaned up… but what do you do with all that candy? You can’t possibly eat it all, right?

Well go ahead and give it a your best shot. But a week from now when it’s still around and you can’t stand the sight of the stuff, you’ll be happy to know that science once again has a solution.

MeteorIf you can get away from the city lights this weekend, conditions are perfect to view the annual Perseid Meteor shower that is expected to peak Sunday night and into Monday morning, August 12th and 13th. Because we will be experiencing a new moon this weekend, there will be no moonlight to interfere with the spectacular show as meteors streak across the sky.
