It’s very probably true to say that the first ever showers were nature’s own; namely, waterfalls. In hot and warm countries, or hot times of year, bathers would stand under waterfalls to cool off and clean themselves just as kids like to do today on a hot day.
It is thought that ancient people would reproduce the effect by pouring jugs of water over their heads and these were often very cold as some ancient civilisations believed in the hot-cold refreshing nature of cold water just as we may do today after a sauna, for example.
Researchers have found that household dust can contain a surprising amount of different chemicals
– over two dozen toxic substances have been identified in samples of typical house dust, including pesticide levels nearly twice as high as in average soil samples. These residues are mainly brought in to our houses on the soles of our shoes, so taking our shoes off before walking further into the house is the first step to keeping your floor looking clean and staying hygienic.
There are more electric cars being brought out all the time, and each new car offers a little bit more in terms of range, top speed and battery power.
The most impressive range on a production family EV will undoubtedly be that offered by the Tesla Model S. The second car to be produced by the Palo Alto startup company Tesla will be available from spring 2012 and will have a maximum range of 300 miles.
This range maximum is dependent on buying the biggest available battery pack to go with the Model S. The base level has a battery pack that will give a range of 160 miles and costs $50,000. Each upgrade in battery will add $10,000 to the cost of the car. There’s an intermediate battery pack which will give a range of 230 miles. The battery packs can be charged in 45 minutes, which is drastically quicker than other EV charging times.

Merino State offers new high-performance and eco Merino wool blends for athletic and outdoor applications and for all seasons.
Wool is increasingly being touted as a performance fiber, and, indeed, it performs quite well as an inherently thermal-regulating, moisture-wicking, antimicrobial, insulating, water-repellent, breathable, comfortable, durable, biodegradable material. Soft, fine-micron Merino wool is used not only in fashion and corporate apparel, but also in sports and outdoor apparel, and for all seasons. Australia- and New Zealand-based Charles Parsons’ Merino State brand offers Merino and Merino-blend fabrics for all of these uses. Its newest performance and eco Merino fabrics recently were launched to the U.S. market at the 2012 Outdoor Retailer Winter Market in Salt Lake City.

Makers of ECOS offer plenty of green: up to $10,000 in prize money.
Earth Friendly Products is going creatively viral; the green company has launched a high-profile video contest on Facebook that already looks like a winner. Entitled ‘Get Washed’ for its #1 selling green detergent, ECOS Liquid Laundry, the contest was conceived by president John Vlahakis to give consumers a chance to experience ECOS and grasp the company’s use of solar and alternate energy in all of its five manufacturing facilities.
We all try to cut down on the amount of fuel we use, both for the sake of our wallets and the sake of the planet.
It can be hard to do less driving if you’re used to the convenience of jumping in the car, but if you want to cut down on fuel, you need to think about leaving the car at home at least a few times a week.
Everyone has heard of hybrids these days, but although some people have gone out and bought them, others still don’t know enough about them to judge if they’re a good buy or not.
So, how does a hybrid work
and how does this make it environmentally friendly? Put simply, the hybrid car uses two sources of power, instead of just the conventional petrol or diesel engine. The hybrid powertrain includes a small internal combustion engine that is assisted by an electric motor. The electric motor is powered by its own battery – increasingly a lithium-ion one as they are lighter and smaller than the batteries made of metal-nickel-hydride, so they reduce the weight of the car (and the energy required to propel it).
If the latest new car sales data for the UK are to be believed, then environmentally friendly vehicle options are beginning to make real inroads into the market.
At the moment
, the sales remain relatively trifling in percentage terms, but they’re still at record levels – which begs the question; if they can do well in such economically depressing times when consumers are generally feeling so cash-strapped, then what will they be like in the good times?
During night and especially at the twilight buildings compose nicely with other elements of the photographic scene. Sometimes it looks stunning, however. There is a small issue with that and forgetting for a while the nice views, think about the energy draw this fully lighted scenery causes.
Why big offices and banks keep lights on 24 hours a day all year long?
Is it the way how they show their consideration and care for the environment? Is it how they take about saving energy and money? I doubt about that because it costs billions. Is that energy suppliers have something to do with that and banks with big corporation help them make bit bucks? Who really benefits from this type of behaviour?
For all the advances in motor technology, cars still look and behave basically as they did 100 years ago. They’re four-wheeled boxes running on an internal combustion engine.
Recent years have seen major advancements, though, in alternatively fuelled vehicles such as hybrid cars or all-electric cars. The world has simultaneously seen big steps forward in solar technology.
So the big question is whether the two will ever be able to come together to give the planet a solely solar-powered car.
The short answer is “probably” – but it will take a while.
There are already solar-powered cars that take part in solar challenges such as the North American Solar Challenge in the U.S. and Canada, and the World Solar Challenge across the Australian outback – whereby teams of budding engineers from universities around the globe build and race solar-powered cars.

These are very lightweight vehicles
, which are wide and flat for minimal wind resistance and maximum solar panel allowance. They usually carry only one person, but can reach speeds of 50 mph and cover hundreds of miles, crossing entire continents without using any fuel; not so much low emission cars
as no emission cars!
At the moment, though, the large solar panels and battery packs required to make such cars practical for everyday use mean solar isn’t a practical option. But it’s on is way, gradually, and the technology developed in the engineers’ challenge events is used by major manufacturers.
As battery technology develops and they get lighter, and solar power improves further by means as yet unknown, then it seems we will see a solar powered car – i.e. on which continually recharges a powerful battery in the same way that all-electric cars currently work. Before that happens, it seems likely that we’ll see solar playing an ever-increasing role in recharging the batteries of electric cars as a supplement rather than sole power source.
