Getting Energy and Clean Water From the Clouds

main

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 to create power. The developers have already built a small prototype to test the device and have done feasibility studies, while the main aim of the funding campaign is scaling up the device to produce economically viable levels of water and power.

UK-based Hivehaus, led by designer Barry Jackson recently unveiled their first modular home, also called Hivehaus, which is a modular home inspired by the hexagonal shape of the beehive. The basic unit becomes a simple, tiny home, but it can also be expanded on any of its six sides to form a unique and spacious family home.

On the face of it, living in a truck does not sound very comfortable at all. But converting a truck into spacious and above all sustainable home is exactly what fifty-year-old animator Joseph Tayyar from Israel did. And very successfully too. His new home is also almost completely self-sufficient, due to a roof mounted solar power array.

Printed Castle Heralds the Future

whole

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 the intricate structure in his backyard by using a large 3D printer that he made himself. His next project is printing a whole house.

Stacking Solar Cells Could Vastly Improve Their Efficiency

semprius_solar_cell

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 been unsuccessfully trying to reach is 50 percent conversion efficiency of solar cells. However, the start-up company Semprius might be on the right track with the stacking technique of solar cells they recently developed.
