SCANA, Dominion agree to pay $25 million civil fine in massive nuclear fraud case

Summer-nuclear-plant

The State – SCANA and its successor company, Dominion Energy, have reached an agreement to pay the federal Securities and Exchange Commission a $25 million civil fine in one of the state’s largest civil fraud cases, according to public court records filed Wednesday in U.S. District Court.

Under the proposed settlement, neither SCANA, a now-defunct company, nor Dominion Energy, its successor company, admit any fault in the multi-billion dollar business failure of one of the state’s largest construction projects ever – the effort to build two nuclear power plants in Fairfield County.

However, under the proposal, neither corporation can publicly claim it is innocent of any wrong-doing alleged in the SEC’s 87-page civil complaint, filed last February in U.S. District Court in Columbia.

What Makes 5G So Fast? – (All About Circuits)

Telecommunications-Speeds

(All About Circuits) – With 5G rolling out more quickly as we approach 2021, it may be helpful to touch on the key technologies that make 5G such a speedy success.

In a recent article, we discussed the basics of 5G technology—a discussion that is no longer in the realm of the hypothetical with 5G now being deployed in practice. One of the key talking points of 5G, at least from the consumer perspective, is its blazing-fast speeds. But what exactly makes 5G so fast? 

While the hardware-level details of 5G speed are extensive, this article will briefly discuss the basic building blocks that bump 5G speeds from 4G and LTE rates. 

As the name suggests, the 5G new radio (NR) requires a new kind of radio technology, antenna, and carrier tower design to achieve speeds of one gigabit per second with latency less than 10 milliseconds. The actual performance would depend on the design of the 5G products and the environment in which they operate.

‘Air-Gen’ Device Generates Electric Power from Ambient Humidity (by Sci-News)

science-news

(Sci-News) A thin-film device made from nanometer-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in the ambient environment, according to a new study published in the journal Nature.

“We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7,” said Dr. Jun Yao, an electrical engineer at the University of Massachusetts Amherst.

“It’s the most amazing and exciting application of protein nanowires yet,” added Professor Derek Lovley, a microbiologist at the University of Massachusetts Amherst.

The Air-gen device can generate power even in areas with extremely low humidity such as the Sahara Desert.

“It has significant advantages over other forms of renewable energy including solar and wind, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and it even works indoors,” Professor Lovley said.

The device requires only a thin film of protein nanowires less than 10 microns thick.

CO2 Sensor Helps to Reduce the Risk of Covid-19 Transmission Indoors – EE Times

EE-Times

Indoor climate plays a key role in health protection, as pathogens remain in rooms for hours at typical air exchange rates in residential and office buildings. An increase in fresh air supply is recommended. To monitor and control the air quality, innovative CO2 sensors like the new XENSIV™ PAS CO2   from Infineon provide precise, cost-effective, and space-saving solutions. – EE Times

National Association of Power Engineers Is a Good Resource for Interest in Power Engineering

NAPE

The National Association of Power Engineers (N.A.P.E.) was first organized in 1882 and is now the oldest active Engineering Association in the United States. For the last 135 years, NAPE has been dedicated to providing career advancement through educational opportunities to its members and the general public. Training and education through NAPE benefits both individuals and facilities alike, by keeping Power Engineers’ knowledge up-to-date, thus ensuring safer and more responsible work practices.

NAPE is an organization completely dedicated to education, the strongest tool in preventing human error when health and safety of many people depend upon the operation of engineering plants for commercial and industrial facilities. 

NAPE Provides Education and Knowledge through its many chapters through the United States, as well as through its many online educational tools.

No matter the level of experience or proximity to a local Chapter, NAPE can provide Power Engineers and HVAC professionals with the necessary tools to obtain and advance their knowledge and education for safer practicing in the field.

The Chattanooga Engineers Club (CEC)

Chattanooga Engineers Club

The Chattanooga Engineers Club (CEC) was established to promote the exchange of ideas and to learn about current developments and trends in science engineering and technology.  The decades since our founding 
have brought many new and better paths of communication–this web site as just one illustration! 

Throughout 2017 the Executive team has wrestled with the question of how to preserve our heritage but also stay relevant to the times.  Our present view of the value we can bring in our community centers on the following:

1.  Engage MS & HS students to consider Engineering careersthrough STEM activities, by connecting with school guidance counselors, and facilitating business open-houses or internships.

2.  Offer members Professional Development Hours (PDH’s) through speakers and presentations.

3.  Expose engineers to work places, innovation centers, educational institutions, etc. by holding Tours.

4.  Advise/consult/interact professionally by building relationships that find synergy.
