Better Way To Desalinate Water

NJIT Professor Discovers Better Way To Desalinate Water – NJIT broke the link to their press release so I removed it 🙁 A university breaking news release web link, sigh. At least far fewer web sites are run by pointy haired bosses that don’t understand extremely basic rules like web pages must live forever.

Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water. Sirkar, who holds more than 20 patents in the field of membrane separation, said that using his technology, engineers will be able to recover water from brines with the highest salt concentrations.

Math and the Mona Lisa cover Math and the Mona Lisa : The Art and Science of Leonardo da Vinci is an excellent book exploring the visionary science of Leonardo da Vinci. More excellent science books that we recommend.

An excellent site for learning more about Leonardo – Museum of Science Leonardo web site (includes classroom activities):

Leonardo da Vinci may seem an unusual topic to study in science. But the more you learn about this remarkable Renaissance man, the more you will realize that he was a terrific role model for applying the scientific method creatively in every aspect of life including art and music. Although he is best known for his dramatic and expressive artwork, Leonardo also conducted dozens of carefully thought out experiments and created futuristic inventions in a time before modern science and invention had really begun.

Water and Electricity for All

Segway Creator Unveils His Next Act

Water and Electricity may not seem like something to wish for if you are reading this post. However for over 1 billion people that do without both it is.

Dean Kamen, the engineer who invented the Segway, is puzzling over a new equation these days. An estimated 1.1 billion people in the world don’t have access to clean drinking water, and an estimated 1.6 billion don’t have electricity. Those figures add up to a big problem for the world and an equally big opportunity for entrepreneurs.

To solve the problem, he’s invented two devices, each about the size of a washing machine that can provide much-needed power and clean water in rural villages.

“Eighty percent of all the diseases you could name would be wiped out if you just gave people clean water,” says Kamen. “The water purifier makes 1,000 liters of clean water a day, and we don’t care what goes into it. And the power generator makes a kilowatt off of anything that burns.”

Kamen’s goal is to produce machines that cost $1,000 to $2,000 each. That’s a far cry from the $100,000 that each hand-machined prototype cost to build.

Quadir is going to try and see if the machines can be produced economically by a factory in Bangladesh. If the numbers work out, not only does he think that distributing them in a decentralized fashion will be good business — he also thinks it will be good public policy. Instead of putting up a 500-megawatt power plant in a developing country, he argues, it would be much better to place 500,000 one-kilowatt power plants in villages all over the place, because then you would create 500,000 entrepreneurs.

More products from his company, Deka Research & Development Corp, including: Hydroflexâ„¢ Irrigation Pump, IBOTâ„¢ Mobility System and Intravascular Stent.

Dean Kamen understands what engineering can do. “Today, almost 200 engineers, technicians, and machinists work in our electronics and software engineering labs, machine shop, and on CAD stations.”

DEKA’s mission, first and foremost, is to foster innovation. It is a company where the questioning of conventional thinking is encouraged and practiced by everyone—engineers and non-engineers alike—because open minds are more likely to arrive at workable solutions. This has been our formula for success since we began, and it will continue to drive our success in the future.

Engineering Graduates Get Top Salary Offers

table of highest paid degrees

Most lucrative college degrees by David Ellis, CNNMoney.com:

The data reflects, college seniors in most majors are experiencing an increase in starting-salary offers, according to a quarterly survey published by the National Association of Colleges & Employers’ (NACE). 83 private and public schools were included in this survey.

Topping the list of highest-paid majors were chemical engineers who fetched $55,900 on average, followed by electrical engineering degrees at $52,899. Despite taking a 0.3 percent dip compared to the 2004-2005 academic year, mechanical engineers took third place with an average salary of $50,672.

Last year 6 of the to 7 highest paid degrees were in engineering (computer science was in 4th place). The graphic to the left leaves off: computer engineering, aerospace engineering and industrial engineering.

Draper Prize for Engineering Medal

2006 Charles Stark Draper Prize Won by Inventors of Charge-coupled Devices

The 2006 Charles Stark Draper Prize will be presented by the National Academy of Engineering to the inventors of charge-coupled devices (CCDs), Willard S. Boyle and George E. Smith, on Feb. 21 in Washington , D.C. Boyle and Smith will share the $500,000 prize for inventing CCDs, which are imaging sensors or optical elements that convert light to digital data. CCDs are widely used in consumer products, such as camcorders and cell phone cameras, as well as in advanced electronic imaging tools, such as telescopes and imaging satellites.

CCDs are the first practical solid-state imaging devices. They were invented in 1969 by Boyle and Smith while working at Bell Laboratories. Because CCDs are silicon-based devices, they are fairly inexpensive to produce, compact, and fairly rugged, making them suitable for commercial product use. Their high sensitivity, excellent stability, and lack of distortion make CCDs attractive for use in scientific research imaging systems. CCDs are capable of imaging a variety of sources, including optical, x-ray, ultraviolet, and infrared emissions.

Administered by the National Academy of Engineering, the Draper Prize is endowed by The Charles Stark Draper Laboratory, Inc., and was established in 1988. The Prize is awarded for outstanding achievement, particularly innovation and reduction to practice, in engineering and technology contributing to the advancement of the welfare and freedom of humanity. The Prize honors the memory of Draper Laboratory’s founder, Dr. Charles Stark Draper, who pioneered inertial navigation. It is intended to increase public understanding of the contributions of engineering and technology. Originally biennial, the Prize is now awarded annually.

Previous years awards include:
2002: Dr. Robert S. Langer for extraordinary contributions to the bioengineering of revolutionary medical drug delivery systems
2001: Drs. Vinton Cerf, Robert Kahn, Leonard Kleinrock, and Lawrence Roberts for the invention of the Internet
