What a Concept! Ask and ye shall receive... at least sometimes. Last week I posted a request for an article by science
fiction writer Arthur C. Clarke, of 2001: A Space Odyssey fame,
describing a geostationary satellite system that was published in the October 1945 edition of Wireless World magazine. Thanks to RF Cafe visitor
Terry W., from the great state of Oklahoma, it is now available for everyone to enjoy. Clarke was not just a sci-fi writer, but also an educated
visionary and card-carrying member of the British Interplanetary Society, who proposed many technological solutions to issues of
his day. In this instance, the challenge was developing an efficient means to distribute TV signals across Europe and the world. Clarke's calculations
for the necessary number of repeater towers proved that concept impractical, so he proposed using modified surplus German V2 rockets to launch
Earth-orbiting "artificial satellites," powered by batteries or solar panels, to distribute signals globally. He calculated power densities,
orbit altitudes and periods, S/N ratios, and antenna sizes. You will want to read this article; it only takes about 15-20 minutes.7-7-2011
Top 20 Defense Contractors Defense Systems recently published their list of the top 20 defense contractors. Topping the lineup are the familiar stalwarts of the industry - Lockheed Martin, Raytheon, etc. Rankings are based on revenue, which by nature, is your tax dollars at work. Sure, it is a lot of money, but they are performing a vital service for the country, as opposed to the billion$ spent on social welfare programs that produce mainly votes for politicians that dole it out.
Toxic Air: Our Other Import from China Yay for us. Our pollution production levels are way
down compared to what they were in the middle of the last century. Seriously, things were getting really bad. Pittsburgh was considered such
a hopeless mess that famed architect Frank Lloyd Wright, whose landmark
Fallingwater home sat nearby, when asked what to do about Pittsburg's terrible pollution responded, "Abandon it." Lake Erie had been declared officially
dead.
Love Canal dominated headlines.
Los Angeles air was (and still is, BTW)
unbreathable. After huge public awareness campaigns. cleanup efforts, and stricter enforcement of pollution laws, the trend halted and has reversed.
That is unquestionably good news.The bad news is that as pollution control got better, companies found continuing manufacturing operations in the U.S. was unprofitable based on what people were willing to pay for their products. Steel, the literal <more> 5-12-2011The 10 Most Valuable Trademarks "The single
largest source of intangible value in a company is its
trademark," says David Haigh,
founder of Brand Finance, a brand-valuation consultancy. Believe it or not, seemingly normal words can be trademarked, like "entrepreneur."
Try using that one in your business name and you will be sued by the magazine that purports to champion entrepreneurs. Even common family names,
if you are the first to do so, are trademark-able (think McDonald's and Sears). You will not be surprised to learn that Google
is the most valuable trademark with an estimated value of $44B. Here is Forbes' (another trademarked family name) list for 2011.

Top 10 Thriving Industries LinkedIn recently published a report on which industries thrived during the 2000-2010 decade. It compliments a list by IBIS World listing those that declined during the same period. VOIP tops the thriving list while wired telecom tops the dying list (although VOIP on cable is still wired). Eco consulting, insurance, and correctional facilities lead the growth list as well. Unfortunately, the need for additional prisons does not include having to lock up those responsible for the ruining of the economy. They still head the government.
EE Life's 2011 Job Satisfaction Survey According to EE Life's latest poll, the divide between engineering and management is widening. Here are the major issues: Trust issues with management. Tend not to feel a part of a given company. Believe strongly that there are not sufficient career opportunities at their companies. Poll results:

Δ Employment '01-'11 Here is a sobering - and enraging - chart of how employment in key sectors has changed in the last decade.
The top chart is change in number of jobs; bottom chart is % change. Health care, educational services, and real estate are among the clear
winners. The Biggest Loser? No surprise - Manufacturing. That's the pitifully lonely line heading in the wrong direction in the top chart. The
manufacturing line covers everything from electronics to furniture to clothing to planes, trains, and automobiles. In one form or another, engineers
and technicians have lost opportunity in every one of those industries. A look at thriving sectors - mostly services - reveals they are largely
ones that have received government subsidization and policy support. You might conclude that our government has purposely damaged manufacturing
since policies have hamstringed manufacturers by discouraging and/or penalizing cheap energy production, imposing crippling environmental restrictions,
denying permits, and regulating small businesses to death.6-23-2011
Sleep Less, Do More
Android smartphone sales surged 888.8% in 2010 according to a Gartner report referenced by
Beta News.
Manufacturers shipped 67.2M Android smartphones last year, up from 6.8M in 2009. That works out to an average 184k Android smartphones sold
per day. By comparison, Apple sold 46.6M for the year an average 127k iOS smartphones per day. The numbers are amazing. Overall, there were
1.6B smartphones sold. That number does not even seem possible given that there were approximately
6.9B people on Earth in 2010, meaning
nearly ¼ of the population, including the young, the old, the rich, the destitute, the healthy, the infirm, the civilized and the uncivilized,
bought a new smartphone. There must be a huge amount of them in warehouses.
Arthur C. Clarke Wireless World Oct. 1945 Amongst other things, futurist / author Arthur C. Clarke was one of the first - if not the first - to
propose a geostationary communications satellite system. The concept appeared in print in the October 1945 edition of
Wireless World
magazine. An original copy of that edition just happens to have come up for auction on
eBay; I have
had a saved search for it set for a long time. The starting bid is £100 ($160). The seller is locating in the UK since, after all,
Wireless World was a British publication. I would love to procure that magazine and scan and publish the Arthur C. Clarke article along with
a few others. The problem is that the final price will probably be beyond my budgetary allowance. So, since I am letting everyone know about
it, I would be eternally grateful if some richer-than-me person would win the auction and then magnanimously either donate or lend it to RF
Cafe. Thousands of website visitors would love you for it as well. Seriously, we would actually love you. How about it?6-30-2011
