Summary

Typical Hot Mix Asphalt (HMA) plants are equipped with hundreds of feet of uninsulated flexible metal "jumper" hoses. The primary function of the "jumper" hose is to transfer hot process oil in a primary jacketed pipe across a connection flange. Traditional insulating technologies that utilize mineral wool and hard aluminum cladding are not capable of servicing these hoses as they have a small diameter and a very tight bend radius. The result is that the "jumper" hoses are left uninsulated and they are a significant source of heat loss costing HMA plants thousands of dollars each year in energy inefficiencies.

Recent improvements in thermal insulation technology have finally enabled HMA plants to insulate the neglected "jumper" hoses and recover significant capital in energy savings.

The Technology

Recent advancements in insulation technology are utilizing closed cell silicone sponge rubber as a primary source of high temperature insulation protection. The advantage of this material is that it has a very low thermal conductivity making it an excellent insulator. In addition silicone sponge rubber is non fiberous unlike traditional mineral wool and it does not required a hard aluminum cladding to contain the insulation materials. The inherent flexibility of silicone sponge rubber in combination with the aforementioned properties, make it an excellent solution for insulating the tight bend radius "jumper" hoses.

Economic Benefits

Insulating 1 ½" OD flexible metal hoses with silicone sponge rubber sleeves (under typical operating conditions) enables HMA plants to recover up to $30 in heat losses for every foot of "jumper" hose in one seven (7) month operating season (assuming a winter shut down). This translates into fuel heating costs savings of approx. $6,000 per operating season (Assuming 200 ft of "jumper" hose. Costs are based on 2005 North America fuel costs).

In most applications the flexible insulation sleeve will pay for itself within the first four (4) months of installation.

Installation Benefits

In addition to the economic benefits, the new insulation sleeve technology is easily cut to length with an ordinary pair of scissors and is quickly installed in the field. In many cases the insulation sleeve may be equipped with a hook and loop closure to further simplify the installation on existing lines without line disconnection or interuption. The hook and loop closure also allows for easy access to process lines while performing maintenance procedures or trouble-shooting system components.

Conclusion

Introducing the HMA industry to silicone rubber sponge insulation technologies will help demonstrate unrealized energy savings while creating a safer workplace environment.

Marijuana Hydroponics - How to Build Your Own Marijuana Hydroponic Garden

These are plans to make a fairly portable, and very inexpensive advanced hydroponic system. These plans only explain how to make the garden itself, and do not explain how to use or maintain it. If you plan on using this garden, you should get yourself a good book on hydroponics, and look it over.
I am intentionally leaving out those parts about plant nutrition, light cycles, etc. so as not to appear to be writing a guidebook for growing marijuana.  It is also to make you seek out another source of information so your knowledge of hydroponics comes from more than just this article.  I do not grow marijuana, and never have.  I'm just a high-tech home gardener with information to share.  If you are caught growing marijuana while using the system described herein, don't even think of running to me, I didn't tell you to grow marijuana.  In fact, I'd suggest planting a crop of cherry tomatoes, which can be fooled into producing fruit indoors year round, and is a very easy plant to start hydroponics with.
Materials needed:
1     5-10 gallon bucket
2     Pieces of PVC or ABS pipe, 8-10" long, 5" or greater diameter.
4     Caps for PVC/APS pipe ends.
1     waterpump capable of about 50 Gallons per Hour (you will need a bigger pump if you choose to make this a larger system)
4'     of hose that will fit the waterpump (often 3/8")
1     TEE joint (or Y-splitter) that fits the water hose
4     clamps for the water hose (one for pump to hose, and 3 for hoses to TEE fitting.)
1     Airpump, airstone, and some airline from a fish tank.
1     Can White epoxy based spray paint
1     Can Black Epoxy based spray paint

Procedure:

1. Everything must be made light tight.  Paint all hoses, the bucket, the PVC/ABS and the lid of the bucket with a layer of black paint.  Let it dry overnight, and then cover it with a layer of white paint to make it reflective, and reduce the temperature of the nutrient solution.
2. Take each of PVC pieces and drill a 1 inch hole on the side, about one inch from the end.  Then epoxy the caps onto the ends of the PVC.
3. Drill the inlet/outlet holes; these should be located on the caps of the PVC.  The inlet hole should be as low as possible or as close to the wall of the PVC, and the outlet-hole should be as high as possible.
4. Now cut two 5" holes in the sides of the bucket (close to the top), and epoxy the PVC in place, so about 2" of pipe (and the outlet hole) are inside the bucket, and the 1" hole is facing straight up.
5. Oxygen into the nutrient solution, and not to dissolve CO2. CO2 can kill root systems. If you are growing outside, or not enriching CO2, then the pump can sit anywhere.
6. Place the water pump in the bottom of the bucket (assuming it is a submersible one) and attach a hose to it long enough to reach the top of the bucket. Cut a hole in the lid of the bucket for this hose to go through. Then attach the TEE fitting to the hose. Now attach hoses to the free ends of the TEE, and run them to the inlet holes on the end of the PVC pipes. Use clamps on the TEE fitting and on the pump itself, but use epoxy to attach the hoses to the PVC. This seal must be completely water tight. Let them dry for 24 hours.
7. Put some water in the bucket and turn on the pump. What should happen is the PVC pieces will fill with water, and then when they are full, they should begin to continuously drain out the outlet holes, and back into the bucket. If you are getting leaks anywhere, fix them immediately. If water is coming out of the 1" hole on the top of the pipe, then either your pump is too strong, or your outlet hole is too small. Fix one or the other.
8. Empty the system (hint, remove the hose from the pump to drain the arms), and replace the water with some form of hydroponic nutrient solution (look in a hydroponics book for details on what exactly to use, or visit a gardening store, and ask)
9. Place your plants into the system. The best way I have found to do this is to take a 1 1/8" garden hose and cut a 1" tube off of one end. Then slit the tube down one side. Wrap the stem of your plant (just above the roots) with polyester fluff (available at aquarium stores, for stuffing into external water filters) and then wrap the garden hose around the fluff. Then force the hose into the hole at the top of the PVC arm. People also have used rubber stoppers.
10. Turn on the air/water pumps, and let your garden grow.
This is obviously just a small setup, but these plans can easily be modified for much larger systems, using longer pieces of PVC, or more than one pair of arms, and a larger bucket to hold the nutrients (I've seen one made with a 55 gallon drum, and 8 separate arms, each holding 4 plants)
I personally use this setup indoors (under a skylight in my apartment) to grow 2 cherry tomato plants. What you do with your own garden is your own business, and obviously I can't be held responsible if you choose to grow anything illegal.

Auto-parts makers bounce back
DETROIT — Companies that crank out gears, hoses, gauges and other parts for U.S. automakers are making a comeback. Many are profitable again, and some are cautiously hiring after months of layoffs.
