Who invented the first digital computer?

Who invented the first digital computer?

According to the video below, the inventor of the first digital computer was John V. Atanasoff. This video tells the story of Atanasoff’s work on creating the Atanasoff-Berry computer. Atanasoff wanted a shortcut to the long calculations needed for theoretical physics. He worked on ideas for a faster calculation system during 1935 and 1937. His idea was to create a chain of mechanical calculators. The idea failed, so in 1937, Atanasoff decided to build a new machine using a binary system, choosing digital over analog.

Boeing Wants to Recycle Dreamliner Scrap

Boeing Wants to Recycle Dreamliner Scrap

Boeing is actively exploring technologies that can be used to recycle its carbon fiber composite aircraft, such as the Dreamliner, when they finish their service life. As a result, a greater supply of lower-cost recycled carbon fiber may soon enter the commercial pipeline from industrial scrap and applications that date back several years. Two companies are partnering with Boeing to develop carbon fiber from recycled sources. They are Adherent Technologies of Albuquerque, NM, and Milled Carbon in the United Kingdom, which already processes more than 500 metric tons of carbon fiber composites per year in a thermo/chemical process .

2008 will begin new wave of environmental regulations

2008 will begin new wave of environmental regulations

In a recent blog from Technology Forecasters Inc., a research firm in Alameda Calif., Harvey Stone, managing director of the Goodbye Chain Group, points to 2008 as the beginning of a new wave of environmental regulations that will extend over a “tumultuous next 10 years.”

Stone says we got off easy in 2007. China and Korea introduced their own versions of RoHS, but otherwise it was a quiet year for environmental regulations. There were no major RoHS or WEEE enforcements and a bill to expand California’s RoHS legislation was vetoed.

He pointed to five changes in 2008 that will put environmental issues back on the front burner:

  1. We have reached the “greening of industry” tipping point. One example is that hundreds of corporate executives are calling for mandatory caps on greenhouse gas emissions and virtually every leading company is launching energy-related initiatives regarding products, facilities and logistics.
  2. It appears we will finally see China RoHS’s Phase 2 Catalog which will point to products that need pre-market testing.
  3. We will see the first wave of implementing legislation from the European Union’s (EU) Energy Using Products Directive, which will require energy reductions for products.
  4. Results of the EU’s review of the RoHS regulation will be published. That could mean that some medical devices as well as control and monitoring instruments will be added to RoHS.
  5. The EU’s REACH regulation will kick into high gear with a 2008 pre-registration period and subsequent registration deadlines over the coming 10 years.
Solar Impulse: A Sun-Powered Plane to Fly Through the Night

Solar Impulse: A Sun-Powered Plane to Fly Through the Night

The first milestone in manned solar aviation was realized in 1981 when the late Dr. Paul MacCready’s Solar Challenger successfully crossed the English Channel running only on energy from the sun. More recently, interest in unmanned solar aircraft was fueled by the realization that high-altitude sun-powered airplanes could stay aloft for months and perform the same functions as communications safelights at a fraction of the cost. To meet this mission, NASA made dramatic headway in the unmanned solar aviation arena with the Pathfinder Aircraft, co-designed by Dr. MacCready’s company, AeroVironment.

 

Nonetheless, no aviation technology is considered truly mature until it has passed the ultimate test: manned circumnavigation of the Earth. The first aerial circumnavigation occurred in 1924, ushering in the age of propeller-driven aircraft. In 1957, jet aircraft came to dominate aviation as three B-52s circumnavigated the globe; with four mid-air refuelings they accomplished the feat without landing. The first helicopter circumnavigation was achieved in 1982, and the first balloon circumnavigation occurred in 1999.

 

As reported in Mechanical Engineering Magazine’s “The Sun Also Raises,” the deck is stacked against manned circumnavigation by a solar airplane. Since keeping pace with the sun is impossible, the greatest challenge is storing enough energy during the day to continue flight through the night. Until an all-night manned solar airplane flight is demonstrated, circumnavigation (and true maturity of this aviation technology) will remain elusive. The major impediment is keeping aloft systems to collect and store energy – these components represent substantial parasitic weight that does not encumber a conventional aircraft. Either batteries or some version of AeroVironment’s fuel cell system for solar-powered airplane will be needed, but at the moment, these technologies are too heavy to remain airborne overnight in a manned aircraft. As reported in the recent Design News article, “Composites Develop Dramatically with Solar Impulse”, significant advances in composite material technology are being employed to close the weight gap.

 

To develop technologies needed to meet the challenges of manned solar aviation, two aerospace entrepreneurs, Bertrand Piccard and André Borschberg, founded a company called Solar Impulse. Their goal is to circumnavigate the Earth in a solar powered airplane by 2011. Trip planning has already begun. The company’s Web site contains an Indiana-Jones-style animation showing the proposed circumnavigation path of the Solar Impulse airplane.

 

This year, Solar Impulse plans to build a 60-meter-wingspan prototype aircraft to demonstrate key technologies. While this plane will not be capable of an around-the-world flight, it will demonstrate the feasibility of an all-night manned flight by a solar airplane, the key enabling feat for the 2011 circumnavigation attempt.

 

If Solar Impulse is successful, the final aviation frontier will be circumnavigation of the globe in an autogyro.

McCain comes on strong

McCain comes on strong

In my forthcoming column, I analyze the presidential field of candidates and look at how the frontrunners change every other week. Well, I wrote the column a week ago and didn’t even mention Senator John McCain. And now he’s a front runner. I should have said the races change weekly!

McCain gives little mention of science and technology and is the only candidate who does not have an energy position front and center on his web site. My column looked at those types of technical issues, analyzing the positions of the front runners. So for all of you who write in when you see the column and lambast me for not mentioning McCain, I am now!!

Timex Ironman: Keeps on tickin'

Timex Ironman: Keeps on tickin'

I have owned two Timex Ironman watches and I just lost the second one after 5-7 years of use. I was thrilled to find that my old one was still keeping perfect time. Believe it or not, the ironman watch line with its Indiglo backlit screen is 25 years old! I was considering buying a fancy watch, but who can argue with the durability and utility of the Ironman. And after my loss, the original watch bailed me out.

I’m getting another Ironman!

Light Matters: War of Currents Vendor:Avnet | Type: Design Guide This resource explains the battle between Thomas Edison, a major stakeholder of direct current (DC) power distribution and George Westinghouse, who believed that alternating current (AC) was a superior technology. Westinghouse's AC system which employed pairs of step down transformers, ultimately proved to be the best method for delivering electrical power over long distances. If the dominant artificial light source at that time had been high-brightness LEDs, it's possible Westinghouse would not have won so easily.
