Could a space-based solar farm become a reality by 2040?

By - May 13, 2014 2 Pictures
Space-based solar power seems like an idea from a Star Trek script, but given the uncertain future of its power generation industry, Japan stands to gain as much as anyone by exploring this potential source of renewable energy. The disaster at Fukushima, limited access to fossil fuels and advances in technology has, at least in the eyes of the Japan Aerospace Exploration Agency (JAXA), added further weight to the notion of a space-based solar power system. The agency is developing a complex roadmap involving a 1 GW extraterrestrial solar farm, a microwave beam and a man-made island in the Tokyo harbor which could be used collect solar energy in space and supply power to Earth by 2040.

Energy-producing Honda Smart Home gives more than it takes

By - April 1, 2014 13 Pictures
With homes and light-vehicles accounting for roughly 44 percent of total greenhouse gases emitted in the US, neutralizing these emissions would certainly go a long way towards a clean energy future. What if these sources of pollution could not only be nullified, but play an active role in reducing our environmental footprint? Such is the thinking behind the Honda Smart Home US unveiled last week, which generates enough solar energy to power both car and home, with a little left over to feed back into the grid. Read More

Orchid House concept inspired by Taiwan's greenhouse technologies

By - March 17, 2014 12 Pictures
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.

Seafloor carpet mimics muddy seabed to harness wave power

By - February 23, 2014 3 Pictures
Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths. Read More

Sensor system lights up wind turbines only when aircraft approaches

By - February 11, 2014
With aspirations to claim 80 percent of its power from renewable sources by the 2050, it follows that Germany is taking a proactive approach to its clean energy transformation. Wind farms, while set to play an important part in achieving this goal, often meet impassioned opposition from disgruntled neighbors piqued by their perpetually blinking beacons. In an effort to address this issue, researchers have developed a sensor system for wind turbines which detects nearby aircraft, switching on a beacon warning system only as they approach. Read More
