Bad data and overwhelmed professionals impede successful employment

Dec 9th, 2016 | By

The conclusion of a year-long New Tech Press investigation of the employment industry shows is it is failing job seekers, employers and the investment community. Some of these services can point to a few areas of success and some are better than others, none are particularly effective. In fact, if a job seeker were to place on roulette bet or buy one lottery ticket for every job they apply for on a job listing service, they would be more likely to win a living wage from gambling than job searches.

Employers and the employment industry rely on the Standard Occupation Codes (SOC) …

Can we make clean energy storage the norm?

This is part two of a three-part series. See part one here.

As the renewable energy industry rushes headlong into the distribution of expensive and toxic energy storage technology, there are signs that cheaper, cleaner, more efficient technologies will emerge soon, two of which were on display at Intersolar.

Flow batteries have been around for several decades, but the clamor for storage systems has brought them out of the labs and into commercial development of late. A flow battery is combination of a fuels cell and a rechargeable battery. The difference between conventional batteries and …

Energy storage is big business, but is it safe?

Judging from the number of companies that exhibited at the Intersolar/EES joint conference in San Francisco, energy storage is the next big thing in green energy. It resolves the problem of intermittent over-and under-production that plagues sources like solar and wind. It comes, however, at a high cost to the pocketbook, the environment and personal safety. The good news is that there are alternatives to conventional storage technology. The bad news is those technologies are only now coming to market and are facing an uphill battle with the technology status quo.

Wind power has a cost… in human life

Feb 29th, 2016 | By

This is the next chapter of our series on energy production. We take a look at wind power, it’s history, application and challenges.

The first time wind power was put to use was in the sails of boats and for more than two millennia wind-powered machines have been a cheap source of power for food production and moving water. It was widely available, was not confined to the banks of fast-flowing streams, and required no fuel. The Netherlands used wind-powered pumps to push back the sea and wind pumps provided water for livestock and steam engines for over a century.…

Three grids, two not ready for alternative power

Dec 31st, 2015 | By

In our first two posts, we talked about how our reliance on turbine technology and carbon-fueled generation is not going to be going away anytime soon, even though it is inefficient. Our next few posts will be looking at the problem of power distribution.

The growth of alternative energy technology has fueled a movement toward distributed generation over grid distribution, which is what we more commonly employ.  Grid power in the US comes mostly in direct current (DC) generation, resulting from Thomas Edison winning the debate over the benefits of DC power offer Nikola Tesla’s alternating current (AC). We …
