Calcium carbonate in powder form

Expensive carbon capture and storage (CCS) projects are gaining momentum around the world as a way to combat greenhouse gas emissions (or is that sweep them under the carpet?), India’s Economic Times has reported that a team of Indian scientists have discovered a naturally occurring bacteria that could help fight global warming by converting CO2 into calcium carbonate (CaCO3) - a common compound found as rock all the world over.  Read More

Febot wind charging concept

We're always on the lookout for new, ‘greener’ ways of saving or renewing energy. South Korean designers Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon have developed the Febot, a small, easily-assembled portable battery charger concept that harnesses the power of the wind rather than using electricity. Place a rechargeable battery inside the Febot and stick it on the outside of a window or wall, or any other outdoor surface, using the suction cap at the base of the unit.  Read More

A similar Heliostat array already operating in Australia

If ever there was a perfect candidate for solar power, the north-west Australian town of Cloncurry is it. The town has long claimed the title of Australia's hottest recorded day - 53 degrees Celsius in the shade in 1889 - and is now is gearing up to produce solar thermal power capable of supplying all of ts electricity needs, 24-hours a day. The system will use up to 8000 mirrors will reflect sunlight onto graphite blocks through which water will be pumped to generate steam that will operate a conventional steam turbine electricity generator. Because heat stays in the graphite, the system will work through the night and on overcast days.  Read More

80% of wars occur in biological hotspots

Since the rise of the state some 5,000 years ago, large scale warfare has been a permanent global fixture. History shows that the motivations for war are different for those ordering the conflict than for those undertaking it and now a startling new study has found 80 percent of the world's major armed conflicts occur in biological hotspots. That is, the richest storehouses of life, the areas essential for both biodiversity conservation and human well-being, are also the regions of the most human conflict. Millions of the world's poorest people live in hotspots and depend on healthy ecosystems for their survival. Is it time for civilization to take political and social responsibility and protect these places? It certainly makes more sense than fighting over oil!  Read More

The Microcycle bioreactor

We live in a society that is creating more toxic chemicals everyday. In nearly all forms of production many undesirable chemicals get produced which cannot simply be disposed of, even in industrial settings. If these chemicals are tipped down the sink or flushed down the toilet they will end up back in our water streams and pollute our precious and already strained environment. The standard solution is to transport harmful chemicals to distant chemical treatment facilities where they can be broken down and disposed of responsibly, but these processes use a lot of energy and often produce many undesirable byproducts such as oily polluting residues that end up in landfill. That's where this ecologically friendly bacterial treatment from Microbial Solutions' comes in. Microcycle, as it's known, turns toxic exhausted metal working fluids into grey water that is safe to dispose of into the sewerage system.  Read More

T-Solar's facilities

Solar panel manufacture is a costly process making it difficult for solar electricity to compete with power generated from fossil fuels. One way of driving these costs down is through the production of larger panels, enabling installation costs to be reduced. To this end, Solar Panel Manufacturer T-Solar Global S.A. has just announced that it has begun volume production of the world’s largest solar photovoltaic (PV) modules. The solar panels are sized at 5.7m2 or 2.3m X 2.6m - that's the equivalent to the combined area of over six 42 inch plasma TV’s and T-Solar says that they are ideally suited for solar farm applications where installation costs can be reduced by about 20% over smaller scale panels.  Read More

The Waste2tricity process

It’s common knowledge that the majority of electricity generation and waste disposal methods currently in widespread use are not very environmentally friendly. New British venture Waste2tricity aims to kill two environmentally damaging birds with one stone by taking carbon based waste, either municipal solid waste (MSW) or waste from business and industry, and converting it into clean electricity, thereby reducing the amount of rubbish going to landfill and potentially making a significant contribution to the UK electricity supply.  Read More

Heliotex solar panel wash system

When we think of solar panels we think of saving energy, burning less fossil fuel and reducing greenhouse gases that contribute to global warming. Few of us however realize that by not cleaning the panels regularly they could lose up to 30% of their power, off setting these benefits and costing us money. To address this problem, Heliotex a Southern Californian based supplier of solar panel cleaning systems and solar panel anti-theft devices has announced the release of the first patent pending automatic cleaning systems for business and home solar panels.  Read More

Cyclone Power Technologies - Waste Heat Engine

Technology capable of generating electricity by extracting energy from heat that is otherwise just wasted is a fairly new branch of renewable technology. A typical co-generation plant uses waste heat from a gas or steam turbine for hot water or space heating. This Waste Heat Engine (WHE) developed by Cyclone Power Technologies operates at temperatures as low as 225F (107 C). The engine can generate up to 10kw from heat sources such as industrial ovens or furnaces, concentrating solar thermal collectors, engine exhaust and biomass combustion.  Read More

The GeoBulb LED light bulb

Not so long ago choosing a light bulb wasn’t too difficult. Just grab one with the desired wattage in either pearl or clear with the correct fitting for your socket. The need for energy efficient lighting means that it's no longer that simple, and given the amount of ongoing research in the area, the range of light bulb options on the supermarket shelves is set to explode. Technologies competing to replace conventional incandescent bulbs include OLED, Compact Fluorescent Light (CFL) bulbs, and of course LED bulbs. LED bulbs offer improved energy efficiency, produce brilliant light and offer long life and this new LED bulb offering, called the GeoBulb II, puts out more light than a standard 60-watt bulb and uses just 7.5 watts.  Read More
