Renewable Energy Prospecting Tools and Modeling – now available
With the recent Fukushima nuclear power plant partial meltdown, the world is now aware of the need towards developing alternative and cleaner, safer and renewable energy to supply the energy and power needs of the world. And to assist in facilitating renewable energy development, there is now a need for precise, easy-to-use renewable energy prospecting tools and using its output to assess the energy potential and the cost of its electricity output.
The energy technology expert has now expanded the usefulness of renewable energy prospecting tools such as the 3-TIER service provider (solar, wind and hydro).
Given the geographical location by specifying its coordinates (latitude and longitude), the 3-TIER provides the annual average wind speed, wind direction (wind rose), wind speed profile (wind speed vs time of year), and wind speed distribution (Weibull chart and constants).
To enhance the value of the 3-TIER outputs, the expert has now in place a wind energy assessment model that takes input data from wind prospecting tools such as 3-TIER that provides at any latitude and longitude and hub height (30, 50, 80 meters) determined from Google Earth or plain maps. The user of 3-TIER can generate and synthesize wind mast and monitoring data on wind, solar and hydro). It uses the daily average at certain times of the year (mid-month at day 15 and end of month at day 30) and interpolates the other days (day 1-14, day 16-29). More »
The Paradigm Shift from Nuclear Energy to Renewable Energy – the Fukushima debacle
The recent nuclear meltdown incident in one of the 15th largest nuclear power plant in the world as a result of a sequence of events starting with an Intensity 9.0 earthquake that initiated a 10-15 meter tsunami wave within minutes (leaving little time for safe evacuation in spite of adequate tsunami warning by civil and military authorities) that engulfed as far as 10-20 kilometers inland along the flat lands of northeastern Japan, and in the process destroying buildings, roads, bridges, flinging ships inland and disabling the backup diesel generation system of the Fukushima nuclear power plant.
There are newspaper accounts that the earthquake isolated the Fukushima nuclear power plant from the grid, and with a non-operable backup diesel generation backstopped only by an 8-hour battery pack, the world was indeed very close to a China-syndrome type nuclear power plant meltdown. Only the timely use of seawater pumped using crude methods to cool the reactor core and the spent fuel pool prevented a full meltdown. Up to now, the nuclear power plant operator has not succeeded in stabilizing the cooling water system and has relied on pumping and spraying sea water over the damaged nuclear reactors and exposed spent fuel rod cooling pools, leading to leakage of hot radioactive and contaminated sea water into the sea thru the minute cracks on the reactor building’s damage floors.
