The Pearl, Solar energy at home

To apply different renewable energy technologies, what is most taken as reference is architecture, then adapting solar panels to structures and designs, and using innovative techniques for the development of new solar panels.

Called under Eco-Arquitectura, the combination of a sustainable building with ways to generate a power using clean energyself-sufficiency, which sometimes is applied from the design itself, and on other occasions is done after the reforms.

On this occasion, we run into the design by David fanchon, carried out a house in the form of dome and that in addition to being surrounded by a large amount of vegetation, known as the pearl.
It has a very modern minimalist design, that it is intended to convert from heat of solar energy in its energyself-sufficiency.

To keep adding flashy details, its roof has been made in the form of dome, and covered entirely by solar panels, as well as having very used nowadays, materials metal on its periphery that dissipate and reversed the heat, avoiding the use of air conditioning or at least that it can be used on very few occasions.

Tower Plastikoleum recycles plastics

It is without a doubt one of the problems which has always been existing in the field of recycling and waste treatment, and that causes more difficulties, what recycling plastic is not as easy as seems, and it is possible to even make it into solar panels, as we have seen previously.

On this occasion, we have before us a pharaonic project named Plastikoleum, which basically consists of a tower for the transformation of plastic in oil, i.e. reverse its manufacturing process.

Its inventor, akinori Ita, has promised that it is possible to generate 1 liter of oil using 1 kilogram of plastic, which can be later refined into gasoline, kerosene, or diesel, although of course, this is not a fairy tale, but a large amount of energy is needed.

To do this, and thinking provided that you are looking for is to avoid the consumption of hydrocarbons (otherwise would not have sense such creation) are available to its around an enormous amount of solar panels, which must have a capacity of close to 10 MW of solar energy.

Under these conditions, this tower would have the capacity to produce up to 60 barrels of oil-for-time.

Treepods, trees artificial ecological

It is difficult to say that a tree is not ecological, when they are one of the greatest exponents of the nature to preserve the world, because that can recycle carbon dioxide from the air and turn it into clean oxygen, but the Treepods, a project designed by Mario Cáceres and Christian Canon, let do it also, but so much more efficient through the use of technology.
But in addition to cleaning the air, these Treepods include solar panels of photovoltaic energy and a system of kinetic energy which collects energy that occurs when using a weight of trees.

This energy that the trees produce is that feeds the process of filtration of the air, but also gives power to a small interior lights that give incandescent appearance to trees at night, allowing to reduce electricity consumption by night lighting.

Including, these trees are constructed from recycled materials and recyclable, and can be recycled in the future if necessary.

Airport Portland energy pump

In recent years has been a turnaround in the obtaining of various renewable energysources, and this has pointed to the so-called geothermal energydevelopment, and on this occasion, applied to the airports, which tend to be one of the axes of increased pollutionnot only by the noise generated by the engines (noise pollution) but also for the enormous amount of CO2 emissions.

Portland Airport

On this occasion, the novelty is that it is working on the Airport in Portland (Maine, United States) to begin to develop its own system of Geothermic energy, which would contribute to the generation of heating and air conditioning throughout the building.

Construction would then consist of a series of pipes that would be located at about 150 feet below a parking lot for employees, found a sink with temperatures reaching an average of 55 degrees centigrade in the majority of the year.

If all goes as it has been planned, in warm periods this system would replace the use of air conditioning, while in winter it would replace the boilers for heating of the airport, which would mean further savings of about 140,000 euros a year.

Save water at home

Save water at home is much easier than it seems and do not require large changes of habits to achieve a consumption more responsible and to help care for the environment environment.

An interesting solution is to apply low flow vents to the faucets of water, causing turbulence in the flow of water and adding air way of reducing the consumption significantly unless we notice major differences in pressure or flow of the water itself.

Thus you can save up half gallon per minute, which is not little, mainly if we take into account that these devices that we apply in the mouths of the taps cost less than $5.

Showers also may benefit from low flow heads that spend less than 2 gallons of water per minute, for low cost and without requiring professional facilities or anything.

Of more Needless to say, that immersion baths are not the best way of saving water and if possible should be reduced to a minimum, since they spend an unnecessary amount of litres of water.

From our homepage you can access all the news, as well as to all the articles of our sections: environment, curiosities...

Solar catamaran

Electric cars and plots are not the only means of transport that used renewables for its operation, since we also including sailing ships and sailing with turbovelas thanks to technological advances, but the turanor planetsolar is too large for it, by what has been built to supply solar power.

It's Turanor PlanetSolar is the first solar catamaran of 31 meters long, 8.8 metres wide and 7.6 meters high, being a vessel more than imposing, and 100% friendly to the environment.

Used solar panels cover an area of 50 square meters, which is not for nothing little, and provided all of the necessary energy for their operation and storage in batteries.

Use Less Plastic

It plastic is one of the materials more practical to facilitate our daily life, but unfortunately, it is also one of the most polluting thanks to that is not biodegradable material.

It is for this reason we should try to avoid using plastic wherever possible to contribute our bit to protect the environment, even if it is from our home.

Use glass or ceramic containers is a good start, as well as bring recyclable or reusable bags to the market, given that plastic bags that we deliver in the markets tend to end up in the trash.

An excellent replacement for these plastic bags are fabric bags, cardboard or friselina, that not only are reusable, but even they can be recycled.

If you drink bottled water, consider the option of the Dewar of filtered water that they come in different sizes (from 10 to 20 liters) and are much more economic.

Wind energy-using affordable alternative energy sources

Wind energy is already in use since ancient times, propelling boats and warships, pumping water to thirsty farmlands and grinding the cereals. But this energy has never been fully used, thanks to the convenience of other energy sources such as coal and oil.

There is a renewed interest in this free alternative source of energy, thanks to the realization that the world's dependence on fossil fuels big complications, including higher costs and environmental abuses.
What's so great about wind energy? There are many advantages to choosing this alternative energy source:
Wind towers can be built on land or water, making them compatible with most locations
Wind power does not pollute the environment
Wind is a source of renewable energy
No harmful by-products are produced by wind turbines and wind energy
Cheap operation means lower energy costs
To generate electricity, a wind turbine is set to a high tower for the collection of kinetic or motion energy created by the wind. This energy is then converted by the turbines in the kind of electricity that a regular household can use.

For personal residential use, electricity generated by a wind turbine on your roof and the current passing through a local utility combined. Why the need for local power supply when you already have wind energy? Wind speed varies, while smaller wind turbines now effective at wind speeds of 7-10 km per hour, under which, little if no electricity is produced. As a result, pick up the slack local power supplies when the wind power generated is insufficient.

In some cases, you may find that your system generates more power than you can use. If your area qualifies for the "net metering", no excess electricity you generate automatically sold back to the local energy utility, where you receive a payment or credit. Once you set up net meter are, the process automatically.

There are some considerations to take into account before installing wind turbines: location, general weather conditions zoning regulations, size of House and amount of the investment. The wind option works best at high locations and generally windy places. Your home should not be blocked by taller buildings or trees, allowing more wind action to propel the blades of the turbine to generate electricity.

There are two wind turbine types-horizontal axis wind and vertical axis wind turbines. The horizontal axis wind turbine produces more electricity, but must be placed to face the wind. The vertical wind turbine can capture from different directions which makes this turbine a popular option.

For the home, can wind turbines rated five to 15 kilowatts offer significant quantities of electricity. A turbine can be very large, or for home use, small turbines with a diameter measuring one meter or less is desirable. Unless you are a serious do-it-yourselfer, consider hiring a consultant to give you the best solution for your specific needs to help. An expert can help with wind speed calculations, the best manufacturers, and installation and maintenance.

With all that the wind blows so free, please consider to use the power for your benefit. By converting wind into electricity, you can significantly reduce your residential consumption with 50 to 90 percent.

Nuclear power plant from Asco | New incident

In Erenovable we get not tired of stress that nuclear energy should be replaced by other forms of energy that are cleaner for the environment and safe society. This is evident by the reality. From the great disaster of Fukushima, to numerous nuclear incidents of "low hazard" that occur in the Spanish nuclear power stations and throughout the world. No we cannot continue relying us Atomic Energy.


Precisely, we returned once again this issue in view of a new incident at the Ascó nuclear power plant, listed as a level 1 according to the CSN (Nuclear Safety Commission) and 0 level according to the IFES (international scale of nuclear accidents).

The incident occurred last April 28, when due to a "human error" was opened a motorized valve isolation of sinks, which resulted in the spill of about 25 m3 of radioactive water from the primary coolant system towards the sink. Sinks rebalsaron, leaving a flood on the grounds of the containment of 5 cm, which resulted in 19 workers who were there to be with his feet wet by the contaminated water.

All employees were subsequently analyzed, without radioactive contamination found in none of them. As they explain, "Fortunately" the reactor was stop to recharge, so the concentration of radioactive material was a thousand times lower than normal while it is operating to power.

Therefore, there has been no harm more... "Fortunately"... definitely something that highlights once more the need to strengthen our A LA ENERGIA NUCLEAR non!

Nickel in photovoltaic cells reducira cost of solar energy

One of the most promising technologies in search of cheaper solar energy production is being studied by scientists of the University of Toronto (Canada).

And addition, it is expected that this reduction in the cost remains reasonable efficiency photovoltaic cells.

Recently published studies have proven that nickel - a material of low-cost - you can replace the use of gold in certain components of the photovoltaic cells.This change of raw materials would reduce the price cells between 40-80%.

On the application of nanotechnology, has been that the full spectrum of sunlight (visible light and infrared light) in the production of energy can be utilized.This improves performance of solar cells based on components of silicones, since part of the light spectrum is not seized with such technologies.

The team of scientists has reached in initial testing an increase of effectiveness of 5 per cent, and expect reach 10 per cent the commercial launch of this new technology.

The promising results just published were part of an arduous process of research.According to relate some members of the team of research of the University of Toronto, his initial hypothesis that nickel could serve to such processes failed to start.Material nickel blocked the normal flow of current, but then dilucidaron that the incorporation of a nanometer lithium fluoride created a barrier that blocked the original reaction to the expected result.

New York extracts energy from waste

It is estimated that a family can generate a minimum of 1.5 kg of waste per day, which in addition to occupying a particular space is thrown into the garbage dumps can be reused if you have the necessary infrastructure for their treatment.

The city of New York has decided to put to work to obtain a source of renewable energy on the enormous amount of waste collected daily in the metropolis, but as an initial step, have decided to do about the water waste.
Daily New York citizens generate an amount of 1.300.000.000 gallons of waste water, which in turn originate a quantity of 1,200 tons of trash that eventually end up on landfills and have the quality of being the environment develop a species of algae.
All waste and algae can be removed by the digesters waste plants, and with the respective treatment has been shown that it is possible to get a good amount of butane (a good alternative for gasoline) and on the other hand the methane gas, also usable.
At the moment, methane gas is used to obtain 20% of electricity from the plant although it was decided to make an investment that allows a greater extraction of these materials in order to market them and supply a large part of the city.

Washing machines: tips to save energy and water

Every electric apparatus we use has his tricks to be able to maximize its efficiency, and can thus work with lowest possible energy consumption . In this article we will take care of the washing machine (the third electrical appliances more consumed in the home) to know how to save electricity and water in their daily use.


Always when we are about to buy a new appliance it is very important to look at the energy label. In the case of washing machines we will find in it information on the cycle of washing efficiency, efficiency in the cycle of centrifuged and the level of water consumption. This will allow us to opt for best apparatus, have a dimension of the saving of money that we will have on the electricityBill.

Another function of the washing machine that allows to save electricity and water is the half load programme, when we wash our little amount of clothing.
Other models have built-in probes of water that they measure the dirt in the water and detect when it is not necessary to follow recambiando.

There are washing machines termoeficientes possessing independent hydrants for cold water and hot water, which is taken from the health, achieving significant energy savings and significantly shortening circuit washing time.

When we start to investigate how consumes a washing machine, it is that a large part of the energy used is going to heat water, reaching up to 80 or 85%.  It is therefore very important to use low temperature programs to regular washings, and leave the high temperatures for very dirty clothes. Another not minor point is to choose good detergents, especially those that have enzymes that work at low temperatures to remove the dirt.
Here you have some other simple tips that will help further reduce your consumption of water and energy:
When drying, use the Sun! But, it is preferable to use centrifuges and no dryers, which latter consumed much more. Use descalcificantes and remember to regularly clean your washing machine filter to remove impurities and lime. This you will be kept in good condition, and will work more efficiently. If you have hired for your home rate with discrimination time, try to put the washing machine in the hours of discount.
