Solar Photovoltaic Energy Systems Explained — Solar PV Panels, Cells, Modules, & Science Of The Photovoltaic Effect

June 5, 2016 in Humans, Space

Solar photovoltaic (PV) technologies are becoming ubiquitous in many parts of the so-called developed and developing worlds it seems. Even in places as seemingly different as Australia, India, Chile, the US, and China, various solar energy technologies have begun to be deployed on the mass level — whether residentially, commercially, or on the industrial-scale (utility-scale power plants).

Who in the urbanized portions of the modern world hasn’t seen a residential solar PV system on the roof of a house? Or an image of a solar PV system connected to a satellite in the far upper-atmosphere? Or an image of a huge industrial-scale solar PV power plant sitting in the desert?

A tipping point has seemingly been reached, wherein the technology has become a notable part of the public consciousness — rather than simply a concern of those in specialized fields of engineering or physical science.

With that in mind, I put together the article below to present a basic overview of current solar PV technologies, and of the science behind the photovoltaic effect itself. Enjoy.

Deforestation Threshold Revealed By New Research — When Exceeded, Extinctions Surge

March 13, 2015 in Animals & Insects, Humans, Plants

A ‘threshold’ for deforestation’s effect on biodiversity in the Amazon rainforest has been uncovered by new research from Cambridge University.

When this newly revealed forest-cover deforestation threshold is exceeded, extinctions surge in the regions affected — with extinctions becoming both more rapid and also more widespread.

This article doesn’t really have a point to it, it’s merely me referencing various stories from various corners of the world and time, that are connected in my mind, for whatever reason.

Olmec Civilization, Specialization, & The Origins Of Agriculture — Common Threads

February 17, 2015 in Humans

The Olmec Civilization was one of the largest and most influential cultural centers to emerge in the Americas over the last 10,000 or so years — and was responsible for, amongst other things, domesticating a fair number of the plants that are commonly eaten as food throughout the world today.

The culture’s earliest known center of activity was the city of “San Lorenzo Tenochtitlan” — where clearly recognizable “Olmec” features were first visible sometime around 1600 BC (3600 years ago).

This is when the giant “colossal heads” first started appearing, as well as some of the earliest evidence of the mesoamerican ball game (including rubber balls, and “stadiums”), ceremonial axes, “baby face” figurines/depictions, the feathered serpent, the long count calendar, and cocoa (what we make chocolate out of), amongst other things.

I’m not interested in spending too much time on this so I’m going to keep it short and sweet.

– Brain-to-body ratios (one of the most reliable markers for what we currently consider to be intelligent behavior) peaked in humans roughly 30,000 years ago — its been generally declining ever since.
