Signifying that the winds of change for Israel’s Energy horizons are truly upon us, Leviathan Energy’s Wind Lotus is now connected to Israel’s national electrical grid, making it the first small vertical axis wind turbine to take advantage of Israel’s feed-in tariffs for wind turbines. Israel Minister of National Infrastructures, Dr. Uzi Landau, dedicated the Wind Lotus connection to the national grid in a ceremony held Monday August 23 in Sde Boker at the Midreshet Ben Gurion School for Environmental Studies where the Wind Lotus is deployed on the school’s rooftop. Sde Boker is a southern kibbutz famed as the home of Israel’s first Prime Minister, David Ben-Gurion. Israel Chief Scientist Dr Shlomo Wald, a strong supporter of innovative technologies in renewable energy also participated.

Leviathan Energy developed the Wind Lotus using principles of aerodynamics that result in less turbulence, hence less noise and vibration, and improves the energy captured from each wind speed. As a vertical axis turbine, the Wind Lotus is in a class of turbines that has the advantages of being able to respond easily to winds from any direction  and the space it needs between deployed units is minimal. This combined with the little low noise and vibration it produces, the Leviathan’s wind turbines have the crucial elements that make it ideal for deployment on buildings.

Dr. Daniel Farb, the Founder of Leviathan Energy Wind Lotus, a new immigrant from the United States, said, “It is historic that in the place where Ben Gurion advocated the use of solar power in Israel, Hezi Yitzhak of Midreshet Ben Gurion had the foresight to purchase a wind turbine made in Israel for their students’ research projects. Small wind energy has even more potential than solar energy to make the world energy-independent.”

Leviathan’s wind turbines seem to offer what we need to take advantage of wind even under minimal conditions.

It offers the following advantages:

  • Easy to fit into niche areas where people live
  • Almost zero earth footprint if placed on rooftops—perfect for a small crowded country
  • Generally moderate wind speeds require turbines that start at low wind speeds.
  • Not interfering with military installations

In addition, far from competing with solar energy production, wind complements solar power. The wind usually peaks in the late afternoons of the summer, when the use of air conditioning is highest, and the output of solar is declining.Combining wind energy solutions with solar energy solutions for peak shaving of the grid could be just the needed profitable mix.

Over the course of simulation and field testing, the Wind Lotus proved itself to be the most aerodynamically efficient and cost-effective small vertical axis wind turbine in its class. Designed using advanced aerodynamic modeling; it sets industry-leading efficiency to begin producing electricity at wind speeds of one to two meters per second.  This capability, significantly better than other similar-sized turbines, means that users in virtually any location can receive power from the Wind Lotus.

Leviathan’s upcoming generation of product, the Wind Tulip, will provide commercial buildings and private users a cost-effective renewable energy solution in many environments. It will be an exportable, world-class product. Combining form and function, the Wind Tulip will be a beautiful turbine that captures the imagination. We are looking for investors to help us move into mass production and establish small wind farms.

Next Generation Small Wind Turbine Wind Tulip

Wind Tulip will be available in both 2.o and 3.5 kilowatt versions for 30,000 and 44,000 shekels (approximately $8,000 and $11,800), respectively.  It promises a rapid return-on-investment, depending on local wind speed.

The Wind Tulip will have the following special advantages:

  1. Its Ecoart design give customers what they want – something beautiful to work in an urban environment.
  2. The Wind Tulip’s low noise and low vibration characteristics make it ideal for rooftop and near-people uses.
  3. Safety: The slow but powerful rotation along with the low vibration means that it is unlikely to loosen its bolts and fly away.
  4. Low turbulence: Unlike other turbines on the market, they can be placed close together and take better advantage of limited rooftop real estate.
  5. Cost-effectiveness: The aerodynamic design is an improvement over other turbines of its class. The price is reasonable, and a wind farm of them with the subsidy can make a 20% return on investment.
  6. Because the turbine starts at much lower speeds than competing turbines, it can make more electricity available for the customer.

” The Wind Tulip is to be the symbol of Israel’s Green Movement. It empowers citizens to benefit economically while taking part in the green revolution.” added Joe van Zwaren, Leviathan Energy Vice President of Business Development.

The Israel government has begun encouraging the use of wind power by offering a feed in tariff to owners of small wind turbines who provide energy to the national electrical grid of up to 1.65 shekels per kilowatt hour.

Minister Landau remarked at the significant contribution new immigrants to Israel are making in the field of renewable energy and intends to inaugurate additional new renewable energy developments in Israel in the near future.

Mr. Yigal Shahor, director of the Midreshet Ben Gurion and Mr. Ronen Reicher, principal of the Midreshet Ben Gurion hosted the event. Representatives of Isralaser who contributed to the manufacturing of the Wind Lotus unit as well from Bara Raviv, the installing company participated in the ceremony.

The Wind Lotus is a vertical axis turbine. This class of turbines has the advantages of being able to respond easily to winds from any direction and with little low noise and vibration crucial for putting on buildings.

Israel has extensive areas that are perfect for small wind turbines. The right small wind turbine offers the following advantages:

  • Easy to fit into niche areas where people live
  • Almost zero earth footprint if placed on rooftops—perfect for a small crowded country
  • Generally moderate wind speeds require turbines that start at low wind speeds.
  • Not interfering with military installations

In addition, wind complements solar power. The wind usually peaks in the summer in the late afternoon, when the use of air conditioning is highest, and the output of solar is declining. So it is a wise decision to combine wind with solar for peak shaving of the grid.

  1. Generating Energy Storage & A Combination Renewable Energy System

    “It is cheaper to save energy than make energy”

    Any renewable energy system that is installed should have extra capacity and be able to convert water into hydrogen which will be used to power a hydrogen generator as a back-up power source.

    We should install a renewable energy system that utilizes solar & wind, when possible add geothermal to the mix.

    A design is needed for a renewable energy system that can generate electricity and heat water with a step down mixer allowing the system to provide water hot enough for radiant heating and at the same time utilize a step down mixing valve to reduce the water temperature to be able its use for hot water in normal consumption.

    A thermal renewable energy system may be able to provide both.

    Prior to sizing up a renewable energy system, an energy audit should be conducted and energy efficiency recommendations should be implemented, that includes changing habits in utilizing energy and utilities in general.

    Habitual changes can save between 20 to 50% of energy & utility consumption.
    When people are considerate not to waste, they save resources and money.
