The Problem Of Condensation

There is always some moisture in the air, even though we cannot see it. When that moisture is allowed to accumulate in a dwelling, the atmosphere becomes saturated and condensation occurs which can eventually result in damage to the structure of the building and its contents. This leads to expensive repairs and maintenance plus associated [...]

Why Cosmologists Like Inflation

Cosmic Snapshots
We saw in the last article that the earlier phases of the universe would have been very hot and filled with particles of high energy. This has led to an influx of ideas from high energy particle physics that has enriched our understanding of cosmic evolution. One such idea which [...]

Decent Homes

In 2000, the government made a commitment to bring all public sector homes up to a decent standard, establishing a 10 year target and an interim target to: “ensure that all social housing meets set standards of decency by 2010, by reducing the number of households living in social housing that does not meet these [...]

Soap to Help Save Water

LONDON: Water needed to wash clothes might soon be reduced thanks to researches who have made a soap whose bubbles collapse once garments are clean.
The soap is the brainchild of boffins at the University of Queensland in Brisbane, Australia.
The researchers have made a “pepfactant”, which only forms bubbles under mildly alkaline conditions.
Normal [...]

It Takes Deep Pockets to Fight Global Warming

GLOBAL warming is by nature a big-enough problem to create the kind of necessity that could be mother, father and midwife to invention. And plenty of big ideas are out there to address it, some that may even lead to substantial enterprises much as our military needs have.

But the ideas being backed in the United [...]

Contemporary Green Residences

For decades cutting-edge architecture and sustainable design have, to a large extent,
existed in separate camps, with little dialogue among the leaders in the each field. In the
world of contemporary residential design, sustainability often ranked well below considerations of style and cost. Many sophisticated designers seemed resigned to the notion that aesthetics would be compromised if [...]

Basics Of Green Housing

Heliodon—or ‘Sun Machine’— In Green House

The Green House includes several interactive features – including its very own heliodon. Heliodons or “sun machines” are devices used to simulate the sun’s movement in relation to a structure. A heliodon can be configured to observe sunlight and shading patterns for clear sky conditions anywhere in the [...]

Why Does a Room Illuminated by a TV Appear Blue?

Three primary colours (red, green and blue) produce colour television pictures. These combine to create a whitish light with a colour temperature close to that of daylight (5,500 to 6,500 Kelvin).

Colour temperature is a way of describing the relative amounts of the different colours that make up light from a particular source. It is the [...]

Biomass

The Office of Energy Efficiency and Renewable Energy’s Biomass Program works with industry, academia and our national laboratory partners on a balanced portfolio of research in biomass feedstocks and conversion technologies. Through research, development, and demonstration efforts geared at the development of integrated biorefineries, the Biomass Program is helping transform the nation’s renewable and abundant [...]

A HOT UNIVERSE

By tracing the expansion of the universe back in time, one can try to understand the physical conditions that would have existed in the past. Such an exercise leads to a very fascinating picture about the early universe.

The most important effect of expansion is the decrease in the density of matter and radiation present [...]

Solar Energy For Homes

A “passive” solar house provides cooling and heating to keep the home comfortable without the use of mechanical equipment. This style of construction results in homes that respond to the environment.
For passive heating and cooling, the plan of the house, careful site selection and planning, construction materials, building features and other aspects of the home [...]

Tips for cost effective Heating, Air Conditioning and Ceilings of Your House

1.Consider the cost of comfort. For each degree you set your thermostat above 70 degrees Fahrenheit, you can expect a 3 percent rise in energy costs.

2.If your air conditioner is turned off accidentally or because of a power outage, switch it off for at least 6 minutes before restarting to prevent damage to the compressor. [...]

Rainwater Harvesting

Water covers about 75 percent of our planet, so on the surface level (pun intended) there seems to be an abundance of this natural resource. So why bother to conserve it? Because less than 1 percent of the water we have is available freshwater.
Add to that the way we use water: Only 10 percent [...]

Box converts car fumes into biofuel

QUEENSFERRY: The world’s richest corporations and finest minds spend billions trying to solve the problem of carbon emissions, but three fishing buddies in North Wales believe they have cracked it.
They have developed a box which they say can be fixed underneath a car in place of the exhaust to trap the greenhouse gases blamed [...]

Worms are killing the planet

HAMBURG: Worm composting could be doing more harm than good to the environment, according to research in Germany.
“Worms produce a significant amount of greenhouse gases. Recent research done by German scientists has found that worms produced a third of nitrous oxide gases when used for composting,” an expert was quoted as saying.
In an [...]

Drinking water

Drinking water is water that is intended to be ingested by humans. Water of sufficient quality to serve as drinking water is termed potable water whether it is used as such or not.
