The problem with conventional Solar Technologies
info@eco-nex.com
Conventional Solar technologies fall in to 2 categories.
Photovoltaics
Most people are familiar with the Photovoltaic System, which looks similar to a velux window on a roof. Photovoltaics are method of creating electrical energy by converting the heat of the Sun.
Whilst a clever idea, it would require a lot of panel space on a building roof to capture enough sunlight to power an entire building.
The cost of installing most equipment on a roof is now proving a block to purchases. The eco-nex solution is to use a Stirling Engine or a Wind Turbine, if eco-electricity is what you seek.
Solar-Thermal-Panels
The second most familiar system for utilising sunlight is the Solar-Thermal Panel. Once again, these resemble velux windows on a roof and are reasonably effective at converting sunlight in to heat for hot water cylinders.
Most Solar-Thermal systems can only supply approximately 75% of the required hot water, because they are static and do not track the Sun. Unless your building was designed with specific geographic co-ordinates, it is highly unlikely that your roof will perfectly follow the path of the Sun or have a perfect elevation either.
Whilst there are a number of companies supplying reasonably priced Solar-Thermal kits, the real problem is in installation. Insurance costs for working on rooves have escalated dramatically over the last few years and even the best engineer will struggle to not break roof tiles. Add to this the disruption of scaffolding around a building and the fears of a leaking roof - it is not surprising that most buyers are turning to the eco-nex solution of using a ground-based solar-dish system.
The problem with Advanced Solar Technologies
Advanced Solar Technologies fall in to 2 categories:
Solar-Steam
It is often said, that everything has already been invented. Leonardo Da Vinci invented an aircraft 100s of years ago, which modern engineers have rebuilt and proved that the original concepts worked. Like the ideas of Da Vinci, modern engineers and scientists are looking to the past for inventions that required updating. One such idea is Solar-Steam.
The age of steam was a great advance for technology, yet materials of the 19th Century inhibited steam from being used on a micro scale. The advent of the combustion engine has both accelarated the technology of mankind, and at the same time put an end to many steam technologies whilst destroying the planet.
Some engineers are working on solar panels with capillary tubes using modern techniques that can convert solar to steam to electricy or heat. Whilst the concept is excellent, few engineering teams have been successful to date in building a marketable technology. It has been over 100 years since steam fell out of fashion, so one may be waiting a good while longer yet before such technology is available.
Solar-Hydrogen-Dish
The Satellite Dish had become a familiar site across the World. Huge communication satellites track the stars for signs of life on other planets, mega dishes beam data and voice transmission around our planet. On many offices and buildings, mini dishes beam television and radio stations in to our daily life.
In the USA, the Government and private industries are ploughing millions of dollars in to Solar to Hydrogen conversion. Undoubtedly, Hydrogen could be the fuel of the future. The reality of the situation is that switching from a petroleum to a hydrogen based economy will not happen overnight. The political and economic ramifications of such a shift are so huge, let alone the infrastructural issues. Not surprisingly, most current efforts are at the municipal end of the spectrum and are not likely to be available to the industrial/commercial markets for many years, let alone the availability to residential users.
Whilst the US Government has invested circa 36 million dollars in to their latest mega solar dish, eco-nex are working at the mini and micro end of the spectrum for commerce and industry. Few people will want or be able to afford a 20-50 metre diameter dish in their back yard along with the hydrogen conversion equipment. Yet the mini solar dish for heating hot water and swimming pools is available on the market today.
