10 Reasons Why The World Should Go Solar

Posted by Andreas Christodoulou

Description :

Guys, what's up? 7K+ people in this amazing group of News lovers and climbing! So proud to be connected with all of you. We have a better way! 

You’ve probably heard of it; Solar Power. The way to go green by using the sun for electricity and much, much more. 

If you take a serious look into all the possibilities that solar power has to offer, you are going to wonder why the whole world is not running on it yet. Here are the 10 reasons why the world should go solar:

1. It saves you money

One of the things that make Solar Power stand out is how on the long haul you are going to save money. Sure, getting them might be a bit expensive, but after a few years your wallet is going to thank you. Money saved can go up to $2400 a year (for homeowners) and up to $6000 a year (for business owners). You could take the family to Disney for that money. 

2. Solar energy is a way to escape the hold countries have on other countries

A lot of natural resources like oil, coal and gas are imported into our country from other countries. This means that when something happens in those countries, like lets say a war, we could potentially be cut off from supplies. Solar Power does not face that problem as it is possible in any country anywhere. 

3. It’s better for the climate 

Critics have pointed out that by making solar panels certain chemicals are released into out atmosphere that form a bigger danger than carbon dioxide. What they fail to mention is that more carbon dioxide is released into the air per day from all over the world than the chemicals used to make solar panels. For solar panels this is a one time thing, once it’s made it’s made and no chemicals are released anymore and that’s better for the climate than your car ever will be. 

4. Jobs 

If there is more solar power used there will also be more jobs for people out there. Especially in this economy those are needed, as unemployment rates are still on the rise in almost all of the countries across the globe. By creating a bigger market for solar power you will also be creating more jobs for more people. 

5. The sun isn’t going to run out of light 

Another of the pros of solar power is the fact that the sun won’t be running out of light anytime soon. However we will be through natural resources like oil and gas eventually. 

6. It has many purposes 

Solar power can be used in an infinite number of ways. The only thing that’s limiting us is our creativity. Currently there are satellites in our inner and outer atmosphere completely powered by solar power. Cars that break speed records are powered by solar power. In Africa water is being distilled by solar power.. Well, isn't that awesome?!

7. It’s easily integratable into your home or community 

Your house probably already has a roof where you can place solar panels, but even for those of us who live in apartment buildings there are great options available. By placing a field with solar panels inside a community, or outside a town when you need more space, you can easily generate enough energy for a whole neighbourhood. Which brings me onto my next point..

8. It’s usable everywhere 

Any country and any person in the world could live off of solar power. It could easily change the world and save a lot of people who are currently dying because of the lack of electricity, heating or drinkable water. 

9. Solar powered roads 

Not that long ago a huge online fundraiser for solar roadways was held. They got way more than their original goal of $1 million and no wonder. Solar Roadways are freaking awesome and here’s why; They will make driving safer for people and for animals, because they light up when anything walks over them, heat up in cold areas so the roads are not snowy and more. Plus they are very durable and take way less maintenance than those asphalt roads. Want to know more about this amazing project?

10. Low maintenance

Solar Power is low maintenance. Did you know that solar panels only have to be cleaned a few times a year? With everything you get out of them that’s just a small price to pay. Once your installation is up, there is almost nothing to do to maintain the installation.

The Bottom Line is: Solar Power has the power to change the world and it’s all up to us whether or not we take all the opportunities it has to offer to make this world a better one.

Sleep Apnoea and Its Prevalence in Europe and the USA

Posted by Andreas Christodoulou

Description :

There are three known forms of sleep apnea: central (CSA), obstructive (OSA), and complex or mixed sleep apnea that is a combination of both central and obstructive and these constitute 1%, 84% and 15% of cases respectively. In CSA, breathing is interrupted by a lack of respiratory effort. With OSA, a physical block to airflow, despite respiratory effort, interrupts the breathing and snoring is common. Overall 99% of all cases are OSA based. 

If you suffer from obstructive sleep apnoea (OSA) - also known as sleep apnea, and by far the most common type, you'll know that this form of sleep-disordered breathing can seriously affect your quality of life and impact your health if left untreated. It is estimated that sleep apnoea affects between 2% to 4% of the adult population in the UK, yet this debilitating condition often goes undiagnosed so we are far from sure.

At 4% there would be approximately 2.5 million sufferers in the UK but very few people are actually being treated currently for the problem.

OSA is a worldwide phenomenon. Studies suggest that in Western European countries from 3-7% of middle-aged men and 2-5% of middle-aged women suffer from OSA, but figures vary widely due to low diagnosis levels.

Living with a sleep apnoea sufferer

Despite the increasing recognition that obstructive sleep apnoea is a relatively common condition, population data used to estimate disease prevalence in the United States and abroad did not exist accurately until about 15 years ago. Since the 1990s much has happened to quantify the levels of obstructive sleep apnea in various populations. A number of studies using large samples representative of the general population are now available and provide prevalence estimates for obstructive sleep apnea in countries such as the United States, Australia, Spain, China, Korea, and India.

According to figures issued by the World Health Organization approximately only 100 million people worldwide have OSA. In the USA, OSA is estimated to affect 1 in 4 men and 1 in 9 women; and affects a total of 23 million working adults. Untreated moderate or severe OSA is associated with a six-fold increased risk of death from all causes, independent of any other illnesses.

Other published figures state much a higher total figure based on detailed analysis of registered sufferers and some of these figures are shown below. If one accepts that the addition of the undiagnosed sufferers would at least double these numbers then the figures are quite alarming.

Country % with OSA    Actual Number

United Kingdom 4,0%    2.5 million

United States 4.1%    18.5 million

Australia 3.1%    0.8 million

India 7.5%    85 million

China 4.2%    57 million

Korea 4.5%    2.3 million

There is evidence that regular snoring and OSA are both independently associated with alterations in glucose metabolism and OSA might be a risk factor for the development of type 2 diabetes. The prevalence of OSA is also found more often in those patients with cardiac or metabolic disorders than it is in the general population.

The prevalence of sleep apnoea is higher in different population subgroups, including overweight or obese people, those of some ethnic groups such as African-American, and in older individuals. The fact that prevalence estimates of obstructive sleep apnea from North America, Europe, Australia, and Asia are not too substantially different suggests that this disease is very common not only in developed but also in developing countries. Moreover, given the widespread under-recognition of this disorder by the medical and lay communities, the public and personal health care costs globally are likely to be absolutely enormous.

Source: World Health Organisation

It is estimated in the USA that although there is a known figure of 18.5 million residents* with sleep apnoea, there are over twice that many with some form of major sleep disorder – 40 million in total. If these figures are to be believed, the difference is mostly attributed to undiagnosed OSA, and the problem is even more enormous than we believe and constantly worsening.

Sources for US Statistics: 27.02.2012 - National Sleep Foundation and The Centers for Disease Control and Prevention.

It is important for us to recognise that obstructive sleep apnoea often goes undiagnosed. Doctors usually can't detect the condition during routine surgery visits and no blood test can help diagnose the condition. Most people who have sleep apnoea don't know they have it because it only occurs during sleep so a family member or bed partner might be the first to notice the distinctive signs of sleep apnoea.

Untreated sleep apnoea can:

•  Increase the risk of high blood pressure, heart attack, stroke, obesity, diabetes and cancer

•  Increase the risk of, or worsen heart failure

•  Make arrhythmias, or irregular heartbeats, much more likely

•  Increase the chance of having work-related or driving accidents

Sleep apnea is a chronic condition that requires long-term management. Lifestyle changes, mouthpieces, surgery, and breathing devices can successfully treat sleep apnoea in many people, and it is critical to get professional help and support if you suspect that you are suffering from the condition described.

How Climate Change Is Destroying The Earth

Posted by Andreas Christodoulou

Description : 

Climate Change Is Real 

Thanks to new studies and noticeable changes in weather and storm prevalence, it’s getting harder to turn a blind eye to the reality of climate change. Since the Industrial Age spurred the increasing usage of fossil fuels for energy production, the weather has been warming slowly. In fact, since 1880, the temperature of the earth has increased by 1 degree Celsius.

Although 72% of media outlets report on global warming with a skeptical air, the overwhelming majority of scientists believe that the extreme weather of the last decade is at least partially caused by global warming.

Some examples of climate calamities caused partly by global warming include:

•  Hurricane Katrina 

•  Drought in desert countries 

•  Hurricane Sandy 

•  Tornadoes in the Midwest 

These storms, droughts, and floods are causing death and economic issues for people all over the world - many of whom cannot afford to rebuild their lives from the ground up after being wiped out by a tsunami or other disaster. 

Evidence also indicates that the face of the Earth is changing because of warming trends. The ice caps of the Arctic are noticeably shrinking, the ice cap of Mt. Kilimanjaro alone has shrunk by 85% in the last hundred years, and the sea levels are rising at the rate of about 3 millimeters per year because of all the melting ice. Climate change is also affecting wildlife - for instance, Arctic polar bears are at risk of losing their environment; the Golden Toad has gone extinct; and the most adaptable species are evolving into new versions capable of withstanding warmer water. 

Despite some naysayers with alternative theories about why global temperatures are rising - including the idea that the earth goes through natural temperature cycles every few millennia - the dramatic changes in the earth’s atmospheric makeup suggests humans are to blame. In fact, 97% of scientists agree humans are responsible for climate change. Since the Industrial Revolution, carbon dioxide levels increased 38% because of humans, methane levels have increased 148%, nitrous oxide is up 15% - and the list goes on and on, all because of human-instigated production, manufacturing, and organizations and individuals work hard to promote an Earth-friendly existence, resistance to change is rampant and actions are slow. 

For instance, while the US Environmental Protection Agency is still working on collecting data to support development of greenhouse gas reduction expectations for businesses, most of their efforts feel more like pre-research than actual change. Other countries have made efforts - such as signing to Kyoto Protocol to reduce their 1990 emission levels by 18% by 2020 - but the only solution will require the whole world band together. 

Steps Anyone Can Take To Reduce Global Warming

1. Driving a car with good gas mileage, or investing in a hybrid or electric car 

2. Switching from incandescent light bulbs to CFL or LED 

3. Insulating your home and stocking it with energy efficient appliances 

4. Recycling 

5. Using green power available in your area

UGGA : Ultra Portable Greenhouse Gas Analyser Fits In Small Case

Posted by Andreas Christodoulou

Description :

Portable gas analysers are nothing new, but Los Gatos Research reckons its latest instrument is the world’s first Greenhouse Gas Analyser to qualify for the label "ultra portable". 

Able to detect the three major greenhouse gases - CO2 (Carbon Dioxide), CH4 (Methane), and H2O (Water Vapour) to a claimed accuracy of parts per billion, the appropriately-named Ultra-portable Greenhouse Gas Analyser, or UGGA, is built into a rugged case small enough to be taken as aircraft carry-on luggage.

Los Gatos says that UGGA can simultaneously measure concentrations of CO2, CH4, and H2O, without suffering cross-sensitivity with other gases. The device consumes less than 70 watts, which the company says is less than a standard light bulb (but, as tungsten bulbs over 60W have already be come unavailable Europe, this isn’t necessarily a universal truth). 

The instrument works on the company’s proprietary Off-axis Integrated Cavity Output Spectroscopy (OA-Icos) technology, a cavity-enhanced laser absorption technique which it says is more precise and more rugged than competing technologies. Being a laser-based technique, the instrument automatically corrects CO2 and CH4 for water vapour dilution and spectroscopic effects. Both are reported as dry mole fractions, enabling accurate measurements without the need for sample drying. 

The choice of technology and the ruggedised case makes UGGA suitable for portable operation, and the package fits within US Transportation Security Administration (TSA) guidelines. Applications include compliance monitoring of industrial emissions and landfills, leak detection, air quality studies, soil flux studies, and other field operations where greenhouse gas emissions are to be monitored.

New Efficient Way to Recycle Carbon Dioxide Pollution

Posted by Andreas Christodoulou

Description : 

Scientists in the United States have discovered a new, inexpensive way to remove excess Carbon Dioxide (or CO2), from the atmosphere, as well as from large industrial exhaust sources, such as factory smokestacks. Researchers at the University of Southern California's Loker Hydrocarbon Research Institute say their new CO2 extraction method achieved some of the highest rates ever reported for removing the potentially climate-changing greenhouse gas from the air under humid conditions. 

Most scientists believe that industrial carbon dioxide emissions are major contributors to global warming. The accelerating increase in the Earth’s average surface temperatures also is believed to be triggering significant changes in climate, including more intense storms, more severe floods and droughts, and major shifts in rainfall patterns. 

Study co-author and Loker Institute director Professor Surya Prakash said the CO2 extraction technique involves a plastic-like substance dispersed in a sandy material called fumed silica.

Prakash says the goal of the research was to create an efficient way to capture excess CO2 from the air and recycle it for use in the production of all the fuels and carbon-based products now made from refined petroleum. He adds that the extracted carbon dioxide also can be permanently isolated from the environment. 

Prakash says he expects to see his team’s CO2 recycling technology in commercial use within three to five years. The USC researchers say the fumed silica materials they developed for the CO2 extractor are much cheaper, more energy efficient and more chemically stable than existing extraction devices. They also report that the new materials can be used multiple times without losing their efficiency.

Prakash said he and his colleagues tested the new materials in humid air because capturing CO2 in humid conditions is especially difficult, and provided realistic conditions for the experiment since most air contains moisture. A report on the new USC study is published in the Journal of the American Chemical Society.

World's Smallest V12 Engine - Built From Scratch - Power To The Handy People!

Posted by Andreas Christodoulou

Description :

Wednesday, back at work, back into the swing of things. Morning all! If you're new here, you may want to subscribe to our RSS feeds. Thanks for visiting!

German engineering outshines every other automobile making nation simply because they are so good at it. But an enthusiastic German automotive part maker, Ralf Drendel, obsessed with V12 engines has upped the ante on the miniature scale, so to speak.

 Made perfectly to emulate the real thing (V12 engine) the miniature V12 is designed to function perfectly with any high-end RC (Remote Controlled) vehicle; be it a RC plane, boat or car.

Having 12 cylinders housed inside a four stroke engine runs on a mixture of high performance synthetic lubricant (10%), Methanol and Nitro methane (5-10%) and produces power of 6 to 8 horsepower with a displacement of 87-cubic centimeters.

This functional model has twin camshaft and overhead valves and doesn’t require any radiator, to add to that the crankshaft has been made from multiple pieces.

Frame of the engine has been made from stainless steel, bronze and aluminum and the finished engine runs on compressed air to cool down and ward off any heat produced.

According to Ralf, the maker of this engine, kits will be available anytime soon so that you can attach this German beast to your choice of miniature vehicle with minimum hassle. So hose, just sit back, hit the play button on the video given below and enjoy the thumping sound of the mini V12 in action.

For those who are interested in watching the whole making of miniature V12 engine watch the video given below, you’ll surely be awe-inspired by it if you are an automotive junkie. :)

Convert Air to Fuel with solar (Tested in UK)

Posted by Andreas Christodoulou

Description :

An British Cryogenics company, Highview Power Storage, is now jumping on the air fuel bandwagon with a demonstration system that can cool air to liquid and store it in high pressure tanks. This is reminiscent of the mdi-air car which has yet to make it to mass market after many years of intense resistance from the automotive industry and associated Euro zone govt departments especially the French.

The British method is not for transportation though. Instead they see a benefit in using bio-mass from waste recycling facilities to provide the energy required to liquefy air and harnessing their cryogenics knowledge to super cool the liquid nitrogen result as an alternative to Li-Ion batteries. When the air is decompressed it expands creating force to be used to power an electric turbine. They claim to be able to get 70% of the energy back from the conversion process with the addition of a little extra heat to increase the rate of expansion of the liquid air. 

Next up they are planning to build a 3.5 MW system to provide power for the local community. It may not be the most efficient way of storing energy but if it is combined with solar and wind it could provide a very stable energy supply for many years. That is going to appeal to any long term project where stable energy is a requirement so they most likely have a decent market segment. If all else fails they can just export the energy to the grid for tax credits or sell directly to a major supplier and become part of the bassload grid supply chain.
