Posts exploring the economic impacts of science and engineering. The value of strong science and engineering practice has many benefits to the economy – directly and indirectly. Many countries are focusing their future economic plans on advancing their scientific, engineering and technology communities and creating environments that support scientists and engineers.

Green Energy

In Ontario, Making ‘Clean Energy’ Pay

Canada’s Ontario province has ordered local utility companies to pay homeowners or businesses for any electricity they generate from small solar, wind, water or other renewable energy projects, beginning next month.

The plan is unique in North America, but it is modeled after similar schemes in Europe that have spawned a boom in small “clean energy” projects.

One more example of green energy projects. Those planning for the future can see that such efforts are needed. And my guess is that those that develop solutions now will be rewarded in the marketplace. Europe and Japan are taking the lead in energy technology and as renewable energy (and energy saving technology) become more and more important those companies that have built up a expertise will benefit.

Engineers Save Energy

Dr. Rosenfield - Fermi Award Winner

Arthur Rosenfeld the 2005 Enrico Fermi Award Winner which is the “government’s oldest award for scientific achievement” according to the Department of Energy. I question that, and on another page they say “one of the oldest…”

“Dr. Rosenfeld is one of the ‘founding fathers’ of energy efficiency, and the legacy of his research and policy work is an entire new energy efficiency sector of our economy, which now yields an astounding annual savings of around $100 billion, and growing.”
…
Rosenfeld received his Ph.D. at the University of Chicago in 1954 and was Nobel Laureate Enrico Fermi’s last graduate student.
…
In 1973, when OPEC embargoed oil sales to the West, Dr. Rosenfeld redirected his career. He recognized the potential for energy savings in the building sector, which uses one third of U.S. primary energy and two-thirds of our electricity. In 1975, he founded a program which grew into the Center for Building Science at DOE’s Lawrence Berkeley National Laboratory.
…
The U.S. National Research Council (NRC) has estimated that energy efficiency improvements developed solely at DOE’s National Laboratories, saved the U.S. $30 billion between 1978 and 2000

Great stuff. Another great example of how much good scientists and engineers can do. And also a good reminder of the economic benefits that are less obvious – such as increasing energy efficiency.

Discoveries by Accident

‘Failed’ experiment produces a bacterial Trojan horse by Katie Weber. Interestingly the usefulness of Penicillin, the most popular bacteria fighting agent, was discovered by accident (and then a smart scientist learning from the accident and applying that knowledge to creating an incredibly useful medication).

As he was puzzling out why what should have been a routine procedure wouldn’t work, he made a discovery that led to the creation of a new biological tool for destroying bacterial pathogens – one that doesn’t appear to trigger antibiotic resistance.

The discovery also led to the startup of a promising new biotechnology firm that has already brought Wisconsin a dozen new, high-paying, highly skilled jobs.

This is yet another example of the power of scientists and engineers to boost the economy and society at large.

What Kids can Learn

This is a fascinating interview discussing what children can learn if given a computer and little, if any, instruction. Very Cool. Links on the progress since this interview are at the end of the post.

Q: This is your concept of minimally invasive education?

A: Yes. It started out as a joke but I’ve kept using the term … This is a system of education where you assume that children know how to put two and two together on their own. So you stand aside and intervene only if you see them going in a direction that might lead into a blind alley.

The interview explores what happened when:

Mitra simply left the computer on, connected to the Internet, and allowed any passerby to play with it. He monitored activity on the PC using a remote computer and a video camera mounted in a nearby tree.

What he discovered was that the most avid users of the machine were ghetto kids aged 6 to 12, most of whom have only the most rudimentary education and little knowledge of English. Yet within days, the kids had taught themselves to draw on the computer and to browse the Net. Some of the other things they learned, Mitra says, astonished him.

China Invests More in Science and Engineering

China to invest 6 bln yuan in scientific infrastructure

The Chinese central government will invest at least 6 billion yuan (750 million U.S. dollars) in major scientific infrastructure projects in the next five years.

China’s National Development and Reform Commission (NDRC) announced Thursday that the 12 major projects include an accelerator-based neutron source, a large area space telescope, marine research vessels, a space remote sensing system and other key projects.

The NDRC will invest a further 5 billion yuan (625 million U.S. dollars) in the third phase of the Chinese Academy of Sciences’ (CAS) innovation project, building or upgrading 50 national engineering institutes and 100 national labs, and supporting 300 national authorized enterprise tech centers.

Engine on a Chip – the Future Battery

micro engine - battery replacement

Engine on a chip promises to best the battery

MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight can, powering laptops, cell phones, radios and other electronic devices.
…
The MIT team has now used this process to make all the components needed for their engine, and each part works. Inside a tiny combustion chamber, fuel and air quickly mix and burn at the melting point of steel. Turbine blades, made of low-defect, high-strength microfabricated materials, spin at 20,000 revolutions per second — 100 times faster than those in jet engines.

Engineering the Future Economy

Today most nations, that have their act together, realize high tech jobs and a highly educated workforce are a huge key to economic success and they (governments often, but also companies, rich individuals and foundations) are taking action to position their country to do well. Anyone that is serious about this should read about How to cultivate Your Own Silicon Valley.

Engineering Jobs in Mexico

Maquila sunrise: Jobs headed back to Mexico:

What we see in Mexico today are things that have more engineering. And the reason why that is occurring is that it’s good to have your engineers in proximity to your manufacturing due to the fact that changes can be implemented much more quickly than if your center for manufacture is halfway around the world.

Today, Mexico’s pumping out more jet engines, semiconductors, and engine harnesses than its old staples like textiles and basic electronics. And that’s creating jobs for Mexican engineers inside the maquilas, like the Gulfstream Aerospace plant in Mexicali.

Read more about lean manufacturing (Toyota Production System) that values the performance improvement over short term savings on our management improvement blog. The kind of thing that allows Toyota to make a great deal of money manufacturing in the USA while Ford and GM can’t seem to do as well.

Turning Trash into Electricity

Florida county plans to vaporize landfill trash:

The $425 million facility expected to be built in St. Lucie County will use lightning-like plasma arcs to turn trash into gas and rock-like material. It will be the first such plant in the nation operating on such a massive scale and the largest in the world.

Supporters say the process is cleaner than traditional trash incineration, though skeptics question whether the technology can meet the lofty expectations.

The 100,000-square-foot plant, slated to be operational in two years, is expected to vaporize 3,000 tons of garbage a day. County officials estimate their entire landfill — 4.3 million tons of trash collected since 1978 — will be gone in 18 years.

No byproduct will go unused, according to Geoplasma, the Atlanta-based company building and paying for the plant.

Synthetic, combustible gas produced in the process will be used to run turbines to create about 120 megawatts of electricity that will be sold back to the grid. The facility will operate on about a third of the power it generates, free from outside electricity.

Engineering Student Contest Winners Design Artificial Limb

St. Joseph's College of Engineering students

St. Joseph’s engineering college students win design contest, India:

Three students of St. Joseph’s College of Engineering received a cash award of Rs.50,000 for their prototype of an artificial limb, presented in the `National Level Engineering Students Design Contest’.

The contest, organised by the Product Development and Management Association (PDMA), was aimed at encouraging engineering students to design innovative products.

Organising secretary K. Chandrasekaran said the event was held to address the gap between education and industry, promoting design education and take students to the logical end of working prototypes.
