Researchers at the California Institute of Technology have developed a laser that could quadruple internet speeds on the existing internet backbone.

 

In an interview with the Washington Post, Amnon Yariv, one of the developers and a former winner of the National Medal of Science, said the quadrupling of bandwidth is just the beginning for the technology.

 

"Our first run lasers, fabricated at Caltech, are capable of of a 4x increase in the number of bytes-per-second carried by each channel," Yariv said in an email interview with the Washington Post. "This number will increase with our continuing work, but even at this level, the economic advantages are very big."

 

According to the Post, the laser operates closer to a single frequency than any other laser created before, enabling it to increase the amount of data it can carry through fiber optic cables.

Although net-zero projects have been creating a lot of buzz lately in the field of green building, the Sonnenschiff solar city in Freiburg, Germany is very much net positive.

 

The self-sustaining city accomplishes this feat through smart solar design and lots and lots of photovoltaic panels pointed in the right direction. It seems like a simple strategy -- but designers often incorporate solar installations as an afterthought, or worse, as a label.

 

Designed by Rolf Disch, the Sonnenschiff (Solar Ship) and Solarsiedlung (Solar Village) emphasize power production from the start by smartly incorporating a series of large rooftop solar arrays that double as sun shades.

 

The buildings are also built to Passivhaus standards, which allows the project to produce four times the amount of energy it consumes!

In high-density areas like the Taiwanese capital of Taipei, people have long looked to expand vertically to make use of the limited land, resulting in a lack of vegetation, high humidity and high energy usage. According to Unicode, a team of Taiwanese architects and designers, 50 percent of the county's housing constructions are either common multiple-story rowhouses or larger duplex apartment buildings, many of which have illegal makeshift shelters on their rooftops to provide extra living space. Unicode has developed a concept house which would give these shelters a greenhouse-inspired makeover, shifting reliance to renewable energy sources and improving Taipei's sustainability in the process.

 

The Orchid House design is inspired by the Taiwan's avant-garde greenhouse technologies that saw the prized Orchid flower develop into a mass-market commodity. The team says that integrating the technologies that already exist in an industrialized market will keep construction costs low and the housing more affordable.

 

The energy system is founded on a system where the leaves of the plant create dewdrops, the roots absorb water to be circulated through the stems and the leaves perform photosynthesis, creating a cycle of water and energy supplied to the entire plant.

 

Custom-made photovoltaic panels sit atop the roof to absorb sunlight, with the energy then converted to heat via a solar thermal water device, creating a hot water system that flows underneath to radiate warmth from below the floor.
