Solaris Energy plans to float solar systems on water bodies to preserve land for other needs

Solaris Energy has won an award for an idea that could help generate renewable energy without compromising on land resources. The company, which is at the start-up stage, believes that large scale concentrated photovoltaic systems could be floated on large water bodies to preserve land for more important needs.

Water Scarcity Spares Just Two Arab Nations by 2015

A new report coming from the Arab Forum for Environment and Development fills in some details on how water availability is going to decline in the region, with all but literally a couple of places remaining above the threshold of severe water shortage in as soon as five years. The report, Water: Sustainable Management of […]

Massive Lunar Solar Power Tower Beams Energy to Earth

This massive astral power tower just won the 2010 Moon Capital International Design Challenge. Designed by Bryna Anderson, a graduate student from Columbia University, the concept is based on American physicist Dr. David Criswell’s proposal for a Lunar Solar Power System. It works by collecting energy on the lunar surface using photovoltaic converters and then […]

Solar Energy Gains Steam—or Rather, Hydrogen

Solar power is arguably the cleanest energy source there is. But it’s also relatively inefficient—arguable from a technical standpoint, perhaps, but certainly not from a practical one. That can soon change. A new Atlantic report says that inventor Lonnie Johnson may have figured out how to turn solar heat into electricity with twice the efficiency […]

1 300 GW of untapped hydropower in developing countries

The World Bank has reaffirmed its commitment to “scaling up” its support for hydropower infrastructure in developing countries, which it describes as the largest source of renewable and low-carbon energy. This policy aspiration, which is contained in a newly published report entitled ‘Sustaining Water for All in a Changing Climate’, points out that only 23% […]

How a solar geyser works (animation)

This is an example of solar water heating system with a vacuum tube collector (there are two main solar geyser collector types, the other one being the flat-plate collector).  Solar energy, whether solar panels (photovoltaic systems) or solar water heating systems are employed, is becoming the major renewable energy source that is reducing our dependence […]

LUMENHAUS – The Future Is Here

An 800 sq. ft. zero-energy house that is completely powered by the sun. A house that wakes you up, tells you how its doing and dresses for the weather. We think it is the future. Someone once said, innovation starts with a dream. Dreams can be in the form of solar-powered houses named after the […]

Solar Islands

Video of Solar Islands — a concept by CSEM, Switzerland (www.csem.ch) Large-scale solar power plants can also harness the sun’s energy from deserts. Where smaller countries cannot spare land for solar energy plants, they may be able to place them offshore (see Green Power Island).  Smaller scale or domestic solar water heating can be accomplished […]

Solar Geysers ~ basic information

In this sunny country, solar energy is an abundant source of renewable energy, making it an obvious choice when seeking alternative sources of energy. Solar water heating & how a Solar Geyser works Solar geysers are built on two basic principles of physics: dark coloured objects absorb heat, and hot water rises. Unlike other systems […]
