It's not an accident that musicians become musicians and engineers become engineers: it's what they're born to do. If you can tune into your purpose and really align with it, setting goals so that your vision is an expression of that purpose, then life flows much more easily. Umar Reyaz (talk) 17:46, 16 August 2016 (UTC) In fourth grade, I learned that reading was serious business, not just a pleasant way to pass the time, and that like medicine or engineering, it had a definite, valuable purpose: to foster 'comprehension.'[reply]

 Books that change you, even later in life, give you a kind of electrical shock as the world takes a different shape.

I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world's energy problems, energy distribution problems. I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on. I hope climate science becomes the big thing.

The majority of power technology innovations and breakthroughs in 2013 occurred in the renewables sector. Power-technology.com lists some of 2013’s major innovations and breakthroughs in energy technology.

Ultra-efficient photovoltaic designs

A four-junction solar cell, developed by Germany's Freiburg-based Fraunhofer Institute for Solar Energy Systems, Soitec and two other research organisations, achieved a record breaking 44.7% efficiency converting sunlight to electricity in September 2013. The solar cell structure comprised four solar sub-cells made from different semiconductor materials, each designed for absorbing different wavelength ranges of the solar spectrum.

Prior to this breakthrough, a team led by Dr Harry Atwater, a physicist at California Institute of Technology, developed an ultra-efficient solar design prototype integrating a multi-junction cell concept using spectral beam splitting technology. The design enables efficient splitting of the sunlight spectrum into six to eight component wavelengths, each producing a different colour of light. Each colour of light passes through a cell made of a specific semiconductor that can absorb it. The design is believed to be capable of a minimum 50% conversion efficiency.

The prototype design used a reflective metal to collect sunlight and direct it at a specific angle to the solar panel with multiple solar cells. The broad spectrum sunlight is split into different colours as it passes through the structure, encountering a series of optical filters. Atwater's team is also working on two other designs based on this path-breaking concept. One of these uses nanoscale optical filters to filter light coming from all angles. The other uses a hologram instead of filters to split the spectrum. Which of these designs will offer the best performance remains to be seen. Umar Reyaz (talk) 18:27, 16 August 2016 (UTC)[reply]
