Printing Houses From Mud
The technology for the 3D printing of homes is still in its infancy, but the idea has great potential in this world where population is growing, and adequate and sustainable housing is just not keeping up. Wasp is an Italian firm that recently developed a 3D printer that can create affordable homes using mud as…

Getting Energy and Clean Water From the Clouds
A team of scientists is currently raising funds through a crowd funding campaign to develop Air HES (HydroElectric Station), which is basically an airship that can extract clean water and electricity from the clouds. More specifically, it does so by harvesting and condensing water vapor, and uses it to spin up an electric turbine generator…

Printed Castle Heralds the Future
Building homes using 3D printing technology is still a new idea, but one day it could well become one of the top construction solutions. Especially if the technology keeps developing at such a fast pace. The most recent successfully completed 3D printing project is a small concrete castle created by US-based Andrey Rudenko. He built…

Spray On Solar Cells
A team of researchers at the University of Sheffield in the UK have found a way to make a spray-on solar cell, which has perovskite as the light-absorbing layer. This new cell’s efficiency is only 11 percent, but it can be produced very cheaply, which could be the first step forward in large scale production…

Stacking Solar Cells Could Vastly Improve Their Efficiency
Harvesting solar energy is a great way to generate sustainable power, but unfortunately solar cells are far from being as efficient as they might be. Currently, commercially available solar cells can convert about 25 percent of sunlight into electricity, and scientists have been trying to create better solar cells for years. One milestone they have…
