New business at the speed of wind

Wind mini turbines tech has been a very popular topic in this blog, so we decided to expand the information. The emphasis is doing on commercial aspects of these wind mini turbines for both rural areas and its new application in cities.

Many remote rural areas and even less remote areas have serious problems getting reliable electricity sources. For example, in Venezuela not only remote areas face this problem but nearly all populations within the country suffer blackouts and electricity shortage. This situation, if less severe than in Bolivarian country, is also common in other American countries.

An ecologically viable way to alleviate these problems in areas with suitable wind conditions – usually where winds blow over 6 meters per second- is generating electricity by using turbines or wind turbines as they are better known.

Main topic of the article deals with most common use of wind mini turbines, which means turbines with less than 100 kW that are intended for auto consumption in places where there is no electricity network. However, with changes in legislation, it is becoming possible to install these systems in cities. This allows the use of electricity generated by turbines for home consumption in buildings where there is already an electric network, such as a home or business that are already drawing power from the grid. In this mode, the energy generated is consumed directly by operating appliances and prevents that his owner buy that energy to the electric company. For example, a conventional turbine with a power of 1.75 kW could generate over 50% of the annual electricity in an average household. The other application, which is already applied in Israel for photovoltaic power and in other countries for wind power, involves selling the power generated by mini turbines to the power network.

 On the trade issue

Many professionals interested in installing the mini turbines commercially ask me where to start because the first step is the assessment of wind resource. There is existing data about this in many areas but there are also special devices that measure wind characteristics in situ. On the issue of costs: Total costs for the installation of a wind turbine can vary depending on several parameters such as the kind of turbine cost, construction contracts, type of machine, project location, and other factors. Components of wind projects cost include site analysis expenses, turbine price and charge, construction costs, permitting and interconnection studies, utility system up-dates, transformers, protection and measurement equipment, insurance, operations, warranty, maintenance and repair, legal fees and consultation. Other factors that will impact your project economics include financing costs, size of your project, and taxes.

–          Small turbines cost about $3,000 to $5,000 per kilowatt of capacity. That means a 10 kilowatt machine can cost between $35,000 and $50,000.

Drip Irrigation systems and water conservation: alternatives and technological innovations

Drip irrigation systems have been widely used as low water consumption systems for irrigation purposes. But which are the trends in 2013?

By Tobias Mendelovici, Agronomist of Hebrew University of Jerusalem and Ocean Business Director.This article was translated from its original version in Spanish.

Drip irrigation systems allow accurate amounts of water application without waste but also allow the integrated use of fertilizers through them. These systems were invented by engineers and farmers in Israel several decades ago. Harsh conditions of an arid territory made these systems were developed as they make more efficient use of natural resources. In fact, over 80% of irrigated areas in Israel use drip irrigation and micro irrigation.

  • Compared with gravity irrigation systems or grooves the water savings in drip irrigation systems ranges by 50-70% and compared with sprinkler systems they have 20% savings.

During my agronomy studies at Hebrew University of Jerusalem for almost 25 years, I remember how water with high salinity levels was used in experimental fields and tolerant crops like tomatoes, melons, asparagus, grapes and olives were drip irrigated. In fact, these systems allow the use of waters with higher salinity levels for irrigation. And since then there have been many advancements.

New technological developments in Israel have allowed introducing the first generation of drippers: auto compensated or compensated drippers as well as high speed production lines for cylindrical and flat drippers.

Drippers are unique in the market since they are designed especially for areas with varied topography, scarce and poor quality water resources which make them suitable for uneven terrain, as well as with sewage and recycled waters.

In contrast with super smart and efficient drip irrigation systems there are irrigation systems called TAPE which are a cheaper competitor and consists of a plastic tube with holes through which water goes out. This product cannot provide special functions that provide drippers, such as cleaning water or high pressure change when water enters to the system and change to zero pressure that allow water to drip out. Furthermore, TAPE tubes do not guarantee that water discharge is heterogeneous through lower tube which is critical for some crops, while for others such as cotton and potatoes it is not as important.

And after describing today and future trends, I end up this article with an interesting story from the distant past of drip irrigation: In one of the field trips I made in Southern Israel near to Ben Gurion University experimental station to a plot that was cultivated 2,000 years ago by ancient farmers of the desert: the Nabataeans . Their agricultural methods were extremely sophisticated. They built terraces and cleaned rocks in the floor and so they managed that every water drop from the rains were collected and directed to the fields by gravity.

Israel: 65 years of technological advances and environmental contributions


Sustainability blogers visiting solar field during professional tour

Author: Naomi Levy, Expert in Marketing and Communication.

Israel celebrates its 65th Anniversary. 65 years of independence, democracy, social integration but also progress in technology, among others, the CLEANTECH. In such a short amount of time, Israel is recognized around the world as the “Silicon Valley” of the Water Technologies. While this statement may seem a little obvious, it is worth remembering it from time to time and, incidentally, to expand data about market on clean technologies in Israel.

Located on the edge of a desert belt, Israel has sponsored since its inception as a State** the development of innovative technologies that have turned it in a world leader. Drip irrigation, desalination and wastewater recycling are some of the evidence of this leadership

** “Israel requires the study of desalination, massive use of solar energy, prevention of useful rain water waste and maximization of power through wind turbines… “ – David Ben Gurion, former Israel Prime Minister – 1955

The global industry of Water and Clean Technologies moves more than 400 billion dollars a year and constitutes one of the fastest growing markets recorded. Israel has an important role in this network thanks to its technological know-how, especially in the fields of water and renewable energy.

The acute water shortage in the country has encouraged the development of technologies to optimize its use. To quote an example, note that Israel has the largest desalination plant in the world.

In 2009 the United Nations published a report which stated that Israel led the global recycling and reused 70% of wastewater. According to Environment Ministry, desalinated water constitutes currently 25% of the country’s fresh water and 40% of drinking water for the household sector.

One of the biggest challenges we face in the last decades is water shortages. The efficient use of water sources becomes more urgent in the globalized world, with the population growing and demanding for more energy, because water is running out. Technological innovation in water is vital. There are many challenges to overcome in terms of scarcity, control, facilities, pollution and even the use of water itself.

From the business perspective, there are business opportunities in water management worldwide. In developed countries, for example, we have the opportunity to innovate in controlling agricultural irrigation and domestic use. In emerging countries we can talk even about transforming industrial water into drinking water.

Israel, with its history of clean technology innovation and an active workforce of entrepreneurs and experts arrived from the field of Local High-Tech, has a clear advantage in development of clean technologies next generation. In fact, it ranked #2 in Global Ranking for Innovation in Cleantech.

Within irrigation technologies, over 80% of Israeli production is exported, while Israeli companies monopolize 30% of the global market.

These data, together with the global trend that points to Israel as a major exporter of all kinds of clean technologies and the excellent trade relations with Latin America, make the tandem ISRAEL – LATIN AMERICA in a secure strategic alliance with expectations of success.

There are already many projects and collaborations regarding cleantech that Israeli companies develops in Latin America but, according to officials of the Israel Export Institute and International Cooperation, there is still some way to go. Latin America offers many opportunities that remain still unexplored.
