Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D

by Aerodyne Research, Inc.  (Oct. 14, 2014)

ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is ...

National Grid Alert Triggers Wave of Enquiries for Renewables Sector

UrbanWind today reported a sharp increase in companies enquiring about on-site power generation, following National Grid’s warning yesterday.   It said growing numbers of British businesses were now looking to move towards ‘energy independence’ to protect themselves from the rising threat of future brownouts. ...

Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

by Inderscience Publishers  (Jul. 7, 2014)

This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems ...

Ultrasonic waves lead to liquid cavitation creation

by GlobeCore Blending  (May 8, 2014)

Theoretically liquid starts boiling when pressure in some sites of a stream decreases to pressure of its saturated steam. Actually pressure of liquid cavitation creation process depends on the physical condition of liquid. If liquid contains a large amount of the dissolved air, reduction of pressure leads to air allocation from liquid and ...

Ocean Thermal Energy and Water Production

by Ocean Thermal Energy Corporation (OTEC)  (Apr. 24, 2014)

Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found ...

Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

by Ocean Thermal Energy Corporation (OTEC)  (Apr. 24, 2014)

Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that ...

Ocean Thermal Energy conversion and the company bringing it to market: clean water for our children

by Ocean Thermal Energy Corporation (OTEC)  (Apr. 24, 2014)

Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favourite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water. This liquid of life keeps us hydrated, ...

Rotating angled plate diffusing wave spectroscopy

by Inderscience Publishers  (Apr. 21, 2014)

Solid–like non–ergodic samples can be difficult to study using standard single speckle diffusing wave spectroscopy as the measurement may lack requisite ensemble averaging. We demonstrate here that this required ensemble averaging can be induced by translating the speckle over the collection optics so that multiple speckles are observed over the ...

Ultrasonic density measurement of uranium loaded organic phase in solvent extraction process

by Inderscience Publishers  (Mar. 31, 2014)

The application of ultrasound technique in density determination of uranium loaded organic phase in solvent extraction can provide a unique solution for online density monitoring of process streams. Earlier various authors have investigated the density measurement of liquid by single ultrasound frequency. In general standard reference liquid ...

Oceans of Energy

by Ensia  (Mar. 10, 2014)

Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into ...
