New and Super Efficient 3D Printer


Using 3D printers to construct concrete houses is eco-friendly and very efficient, so it’s a real shame it is not yet used more widely. However, there are a few people making real breakthroughs in this field. One such is Nikita Chen-yun-tai, an engineer from Russia, who has recently built a 3D printer called Apis-Cor. Read more »

Sustainable Rooftop Living


Rooftop living is not something that’s often mentioned on this blog, but from a sustainability point of view, it makes a lot of sense. Especially when it comes to urban living, and lack of adequate and affordable living space there. The Jewel Box, designed by Clear Studios of New York City, is a great example of a housing solution on the roof, which is also all around very sustainable.

Hybrid Solar System That’s Very Efficient


A team of scientists from Brunel University London, UK has come up with a solar panel/heat pipe hybrid system, which basically turns the whole roof into a solar power generator. This makes the panels a lot more efficient, since this system is able to harvest more solar energy than just solar panels alone.

Wind Turbine That Stores Power


The main problem with using renewable energy sources is that they are not as reliable or consistent as traditional sources. This is especially true of wind energy, since wind turbines work at generating power until the wind is blowing, but stop once the wind stops. Read more »

Safer and Better Roof Alternative for Low Income Families


Families from the poorest regions of the world more often than not cover their already lacking homes with corrugated metal roofs. It’s a low cost solution, but in most cases doesn’t prevent leaks, and certainly has very little insulation value. Read more »

Build Your Own Solar Power Concentrator


Go.Sol has just released a free solar concentrator construction guide, which can be used to easily build a 0.5kW solar concentrator that has a mirrored surface area of about 1 square meter, using only locally available materials. This is part of their initiative to eradicate energy poverty and breaking down the barriers to solar power access. Read more »
