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.

When looking into off-the-grid heating and power sources for the home, those interested might soon be getting a new option. The Dresden, Germany-based Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has joined forces with the heater manufacturer Vaillant and together they have come up with a domestic fuel cell system, which uses natural gas to produce both heat and electricity.

Two Russian scientists, Leonid and Sergey Plekhanov, both of the Moscow Institute of Physics and Technology (MIPT) are trying to crowdfund the building of a prototype of Nikola Tesla’s Wardenclyffe tower, which could allow for wireless transmission of power. Should they succeed, it is conceivable that the entire planet could be powered by renewable energy sources with very little energy loss during transmission.

Rooftop Mounted Wind Turbines That Make Homes Self-Sufficient

When it comes to renewable energy, wind turbines are certainly one of the greener and more sustainable options. Their biggest drawbacks is that they have to be large to produce enough energy, and that they make a lot of noise, which is why they haven’t yet been widely adopted by homeowners. However, The Archimedes, a Holland-based renewable energy start-up is currently working on a solution to this problem. They are designing a wind turbine small enough to be mounted on the roof of a typical home, but which is still highly efficient at converting wind to energy and does so nearly soundlessly.

In late 2013, Coca Cola in partnership with several global and local organizations, began deploying so-called Ekocenters, which are primarily mobile clean water sources. These Ekocenters are build out of shipping containers and their main aim is purifying water and delivering it to developing communities across the world with a special focus on groups within the Bottom of the Pyramid (BoP), which is the largest, and also poorest socio-economic group in the world, comprised of about 4 billion people living on less than $2 a day.
