Thanks every one.. Setting up the new room and adding some lighting to the old one I was abel to add 2 more lights making my next grow 8 x1000. Also I am going with drain to waist on tabels.Using Coco with a 1 hp chiller gonna run Casey Jones, Masterx Bubba, Giesel, Deep Chunck x Strawberry cough Clones are rooted and ready to go..Got a pic to post this is what I am shooting for next run ..

Nice set up DAMN!! with all those strains what would you say was the best one or even your best three? Not sleepy bud ,don't like sleepy bud, Peace out Headband707

woops. that'd be (16) 600 watt bulbs in that pic.

i knew of a guy running that same number in Florida... rented a house on each side of the house that he owned. Pulling electric from 3 different houses he never had to worry about uncomfortably high power consumption. I'm leery of running over 6k ju-ju. 9600 watts (plus a.c. or whatever else) ... not where i'm at now. At that point i think i'd be looking at the greenhouse. But, hell, more power to 'em.

with the advance techonlogy of micro power generation is it not realistic to think about that again ... I mean some of the operations certainly would have the cash flow to support that kind of captial expenditure? there seem to be spo many different options for power off the grid ... ? just thinking out loud?

they say it takes 20 years to see a return on your investment in a solar panel setup. Now if you planned on sticking around for 20 years (and own your home) ... and had the money to invest... then it seems like a safe investment. I could see a greenhouse having lower cost and higher production than that afforded by a 20k solar panel upgrade, however.

Yea the practicalities of solar and wind have some real challenhes. I was thinking of microturbines for either hydro or natural gas fired generation. But its been a while since I looked at these. Capstone Turbines out of California seemed to have a very viable product. Not sure itf that ever got off the ground. This is another one that I have seen reference to but have not looked into it alt all.

Tahoe have you seen people convert old alternators into a PMA? It is supposed to increase output and efficientcy 4-5 times over. People are using them to build cheap home-made wind generators.

no I have not, I'll have to take a look into that .... thanks for the thought and the heads up .... walking on!~~~~~

I was thinking something similar....... and using water as a constant instead of wind (but wind and sun too, just in smaller proportions, )

Chena Hot Spring said:

Chena Horticulture Projects
Chena Hot Springs is working toward becoming a self-sustaining community, and an important part of making this vision a reality is to strive for greater independence in food production. Chena installed a small test greenhouse in 2004, which has operated year round and is heated entirely with water from our geothermal resource. Last January, we were able to maintain greenhouse temperatures of 78°F while outside temperatures dropped to -56°F, which is typical for Interior Alaskan winters.

This 134°F temperature differential was the largest recorded for any controlled environment production facility in the U.S. last year.

​

Chena has recently added to its controlled environment facilities with the construction of a new 4320 ft2 greenhouse to provide our restaurant with a greater variety of fresh produce on a year round basis. Crops planned for the greenhouse include tomatoes, lettuce, green beans, peppers, cucumbers, and numerous greens and herbs. Chena Hot Springs is also working in partnership with the University of Alaska Forestry and Agriculture Experiment Station on a controlled environment research project for investigating the opportunities of establishing similar projects throughout the State of Alaska, using geothermal or other waste heat streams.

Rusty Foreaker, our Garden and Greenhouse Manager, manages all our production gardens and greenhouses, along with a staff of 3 interns.

Project Overview ...
Alaska has more geothermal resources than any other state in the country, and yet none of these resources has been developed for power generation prior to 2006. In 2004, Chena Hot Springs Resort entered into a partnership with United Technologies Corporation (UTC) to demonstrate their moderate temperature geothermal ORC power plant technology at Chena Hot Springs.

Project partners include:

• Chena Hot Springs Resort
• Chena Power
• United Technologies Corp.
• Department of Energy
• Alaska Energy Authority

The Chena geothermal power plant came online in late July 2006, putting Alaska squarely on the map for new geothermal technologies. Chena Hot Springs is the lowest temperature geothermal resource to be used for commercial power production in the world. We hope this will be the first step toward much greater geothermal development in the state. The cost of power production, even in semi-remote locations such as Chena, will be reduced from 30¢ to less than 7¢ per kWh once the UTC plant is installed and operational.

The challenge for moderate temperature small scale geothermal development has been to bring the cost down to a level where it is economical to develop small geothermal fields. UTC has been working toward that goal. In the past, small geothermal power plants have been built to order using tailor made components, which has greatly increased both the expense and the lead time for such units.
UTC’s Research Center has teamed up with their sister divisions, Carrier and UTC Power, to reverse engineer mass produced Carrier chiller components to dramatically reduce the cost of production, and allow for modular construction. UTC has already proven this technology with the release of their PureCycle 225 power plant in 2003, which is designed to operate off waste heat applications.

How it Works ...
Because the geothermal water at Chena Hot Springs never reaches the boiling point of water we cannot use a traditional steam driven turbine. Instead a secondary (hence, "binary") fluid, R-134a, which has a lower boiling point than water passes through a heat exchanger with 165°F water from our geothermal wells. Heat from the geothermal water causes the R-134a to flash to vapor which then drives the turbine. Because this is a closed loop system virtually nothing is emitted to the atmosphere. Moderate temperature is by far the most common geothermal resource and most geothermal power plants in the future will be binary cycle plants. Here are the steps in the cycle:

STEP 1: Hot water enters the evaporator at 165ºF (480gpm). After the hot water runs through the evaporator, it is returned to the geothermal reservoir via our injection pump and injection well system. Some of the water is also used to heat buildings on site before it is reinjected.
STEP 2: The evaporator shell is filled with R-134a, a common refrigerant found in many air conditioning systems. The 165ºF water entering the evaporator is not hot enough to boil water, but it is hot enough to boil the R-134a refrigerant. The evaporator is a giant heat exchanger, with the hot water never actually coming in contact with the refrigerant, but transferring heat energy to it. The R134a begins to boil and vaporize.
STEP 3: On initial system startup, the vapor bypasses the turbine and returns directly to the condenser via a bypass valve. Once there is adequate boiling/evaporation of the refrigerant, the bypass valve closes and the vapor is routed to the turbine.
STEP 4: The vapor is expanded supersonically through the turbine nozzle, causing the turbine blades to turn at 13,500rpm. The turbine is connected to a generator, which it spins at 3600rpm, producing electricity.
STEP 5: Cooling Water enters from our cooling water well which is located 3000ft distant and 33ft higher elevation than the power plant. Cold water (40ºF-45ºF) is siphoned out of this well and supplied to the power plant condenser at a rate of 1500gpm.
STEP 6: The cooling water entering the condenser and recondenses the vapor refrigerant back into a liquid. As in the evaporator, the condenser only allows heat transfer to occur between the refrigerant (in the shell) and the cold water (in the tubes within the condenser). The two liquids never actually come in contact.
STEP 7: The pump pushes the liquid refrigerant back over to the evaporator, so the cycle can start again. By doing so, it also generates the pressure which drives the entire cycle.
