Google plans to spend "hundreds of millions" on Green Energy in 2008

Check out the Meglev wind turbine
http://www.breakitdownblog.com/meglev-wind-turbine-1000x-more-efficient-than-windmill/

It is able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, it could operate in winds exceeding 40 m/s.

Amen Larry! People come here for sun, sand and sea and two of those 'pretty but useless' resources, according to the old logic, are now shown to be highly productive! Yet, our politicians repeatedly demonstrate that real problem solving and real vision isn't what they are about. I pray that Ingraham decides that he wants to be remembered as the greatest PM in the history of this nation and chases that legacy firmly while hopscotching over the prattling of the peanut gallery in parliament. Please Mr. Ingraham - lead and make the Bahamas great. You can do it - the nation will rally behind you.

Larry would like to know where the studies were taken for wind speed, because i have figures that differ. If Nassau was the center this is understandable. However look where the ocean thermals and currents run. The temprature of the deeper water like on the eastern islands of the Bahamas differ greatly. Since many of the inland or central located islands like Nassau, the Berrys and even Andros are basically located on a plateau. This in turn makes the water temprature just a few degrees less than the land. However if you look at the differential between ocean temps and land temps for places like Abaco, Exuma and Eleuthera's east coasts there is a larger variance which increases thermals.
Also wind can produce power for about $0.07/kw.

I have asked for clarification.

The Haley & Aldrich report used wind speed data published by the USDOE National Renewable Energy Laboratory (NREL) that was collected by NASA satellites between July 1983 and June 1993.

The report cited an average January wind speed of 5.5 m/s for New Providence as wind speeds are highest in winter. This data was calculated for a height of 10 meters. We used 10 meters because this would be more applicable to smaller, lower powered turbines that may be used by homes or business (as opposed to bigger, utility applications). Wind speeds increase as one goes higher.

The January data reflecting height is as follows:
10 meters - 5.5 m/s
50 meters - 6.6 m/s
100 meters - 7 m/s

For reference, the July data is:
10 meters - 4.4 m/s
50 meters - 5.4 m/s
100 meters - 5.9 m/s

The significance of these wind speeds relates to the turbine cut-in level below which no electricity is produced. As an example, GE utility wind turbines rated between 1.5 and 3.6 MW have cut-in speeds of 3.5 to 4 m/s. Smaller home scale units will have lower cut-in speeds closer to 3 m/s.

According to the NASA data, the wind in New Providence in January blows at 3-6 m/s 50% of the time, so much of the time the turbines would not be generating power. This would result in a low capacity factor.

Based on this data our report suggested that utility scale generation is unlikely to be feasible because of the limited amount of time the wind would be blowing at economic speeds.

The NASA data does predict higher wind speeds on the Family Islands so smaller turbines with lower cut-in speeds may be feasible for use in the Bahamas. Also, the NASA data is based on satellite measurements, so actual wind speed measurements may show different results.

Suggest you look at www.ciupinternational.com, this program is being adopted in Indonesia to supply electricity and potable water through the creation of a micro economy linking 3 technologies Biomass, low cost hydrogen fuel cell and reverse osmosis. This program is financially self sustaining with a zero cost base for the electricity.

DEAR SIR
GREETINGS
LOGIC-CO IS AN ENVIRONMENTAL COMPANY HAS
RENEWABLE ENERGY: ELECTRICITY.EXTRACTED FROM THE LIGHTNING:
THE RATE OF LIGHTNING IS 100 FLASH PER SECOND ALLOVER THE GLOBE. IF USA HAS 1% OF THE TOTAL FLASHES THIS MEANS 1 FLASH PER SECOND.
FOR YOUR KNOWLEDGE, ONE FLASH = 4 STROKES.
EACH STROKE HAS (10)^12 WATT.
THIS MEANS : WHEN LOGIC-CO SUCCEEDS TO GET ONE FLASH ,AND TRANSFORM IT TO ELECTRICITY == THAT IS EQUAL TO A POWER STATION 0F 20 MW WORKS FOR 50 HOURS CONTINOUSELY.
IMAGEN IF WE COULD TRANSFORM ONE FLASH PER MINIUTE ALLOVER USA.
IN THAT TIME NO NEED FOR ANY FUEL COMBUSTION THAT POLLUTES THE ENVIRONMENT.

NOW LOGIC-CO IS SEEKING A PARTENER IN USA TO CLEAN THE ENVIRONMENT, PRODUCING FRIENDLY ENVIRO-ELECTRICITY.

I hear lots of talking about it, but nobody is installing these systems in the Bahamas because the government does not allow Net Metering. Until this is changed, no one will get the full benefit of their Wind/PV/Deep Ocean Current/Lightning/ETC. The problem is, you are able to generate much more power than the average person can consume in 24 hours, even with a small system, but this power is all generated in 5-6 hours of sun. Bahamians need Net Metering so they will get the credit for ALL the power they produce with these private systems, not just the power generated during run times. Making power at .07/KwH is not a problem, but you have to be willing to pay for this power, up front, with the cost of the system. I can show you many systems in California, that generate power at that installed cost. With no incentives from the Government, power can still be produced with Net Metering for around .15/Kwh, which is less than half of what you are paying for power today, but again, you have to be willing to write the check today, for the savings over the next 20-30 years. Hopefully, the Bahamian Government will "get it", and with the help of a lot of lobbying by private persons in the Bahamas, and allow Net Metering, so Bahamians will get the benefits of these systems.
