There’s a lot of surface area on this planet for solar panels. The ocean’s are a vast area to utilize this solar technology.  But,  the weather can make the installation and use of floating solar arrays difficult.  That’s not the case with LSAs (Liquid Solar Arrays) by Sunengy Pty LTD.

The floating solar power units, called Liquid Solar Arrays (LSA), use concentrated photovoltaic technology where a lenses direct the light onto solar cells and move throughout the day to follow the sun.

The company says the advantage to floating a solar power plant is that it erases the need for expensive structures to protect it from inclement weather and high winds — when rough weather comes along, the lenses just submerge.  Floating on water, whether it be the ocean, a lake or a tiny pond, also keeps the solar cells cool, which increases their efficiency and lifespan.

“The LSA system is based on floating solar collectors made mostly of plastic. Each has a very small area of silicon photovoltaic cells at the water surface with a large, thin plastic focusing lens rotating slowly above to track the sun. The water cools the silicon cells and in bad weather the lens is protected by rotating it fully under the water to avoid damage in high winds. ”

What is liquid solar array technology: In this technology, lens and photo voltaic cells are made to float on the water.  These absorb solar energy during the day.  There is no need to undertake any construction in water as these are made to float with the new technology.  This can withstand all adverse weather conditions.  This new technology will convert the dam into a big battery.  Solar energy can be stored without any cost.  Liquid Solar Array technology provides an opportunity to maintain water resources more effectively.

Special features of LSA: LSA technology is cheap and it can even withstand cyclones.  Land is not needed for establishing this plant and so there will not be any problems for procuring the land.  In India, there is 30 thousand square kilometers of water area and even if 1% of it is utilized for this technology, electricity that is equal to the electricity produced by 15 big thermal electricity plants can be produced.

What Is a Composite Part?

A part that combines a resin and reinforcing strands can properly be referred to as a composite.  This includes what is commonly referred to as fiberglass (technically, it should be called fiberglass reinforced plastic), but there are many other materials that are used in composite parts.  To achieve desired properties in composites, the chemistry of the resin used, the type of reinforcing strands, and the ratio of resin to reinforcing strands can be varied.  In general, the more strands in the mix, the stronger the final part becomes.

Why Mold?

There are many desirable features of molded composite parts.  Molded parts are almost always more durable, repairable, heat-resistant, and lighter than comparable strength carved wood parts, and they don’t soak up oil or moisture.  In the case of a molded composite cowl, its thin wall property (about 0.05"…and you can’t carve a wood cowl to match!) gives much better air flow around the motor as a big side benefit.   Molded composite wheel pants can handle bigger wheels and mount more conveniently.  Other possibilities are wing tips, gear legs, dummy exhausts, spinners, etc., and all are made in a similar way.

Once a proper mold is made, composite parts can be replicated quickly and easily, each one almost identical to its predecessors.  So, you can make as many parts   as  you and your   friends  need,  you  can  sell   them,  or ,   in  the event  of   a   crash,  make   a  new one   exactly  like   the original   in  just   a   fraction of   the   time   it  would  take   to carve   and hollow  another .

Molds and Plugs

Actually, anything you can lay resin in or on and pull away a part with the opposite shape can be considered a mold.  Male molds can be used, but a part made from a male mold has a smooth interior and a rough exterior, which requires quite a bit of work to make ready for a finish. A female mold, on the other hand, produces parts with smooth exteriors, so every part molded in one will come out with a smooth exterior that is exactly the shape desired.  To create a female mold with a smooth, perfectly-shaped interior cavity, a male plug is carved and finished, and the female mold is cast around the male plug.  This requires just a bit of extra work, but keep in mind that there is no need to hollow the plug, so making one goes quite quickly.

Plaster and even composite materials can be used to make a female mold, but in my experience, the absolute best overall material to use is RTV (room temperature vulcanized)
molding rubber.  It’s easy to handle, and a female mold made from it is flexible enough to allow a flex and peel technique to free the molded part without doing any damage to the mold, so it can be used over and over again.


Polyester or Epoxy?

Polyester is cheaper and weaker than epoxy, but it’s certainly adequate for first attempts. Polyester gets drops of hardener, more will accelerate the cure.  A down side is that finished parts often have pin holes. Polyester has a strong odor, and you need to wear eye protection because the catalyst can be highly dangerous if it gets in your eyes.

Reinforcing Fiber

The material used for reinforcing fiber has great influence on the overall strength and ultimate weight of the finished part.  Molding is best done with woven cloth, typically two to four ounces per square yard, in as many layers as needed to get the desired strength. Materials most used in composites for model applications are E-glass (fiberglass, white color), Kevlar (yellow), or carbon fiber (black).  E-glass is the least expensive and is fully adequate for most molding.  Kevlar is much more expensive, difficult to bend and cut, and would be best to avoid if you’re just starting out.  Carbon fiber is the strongest, but by far the most costly, hard to buy economically in small quantities, and is best left for after you’re a seasoned molder.  Carbon veil is easy to handle, but it’s not well-suited to molding composite parts typically found in models.

In full-scale aircraft composite parts, the weight ratio of the fibers and the resin is carefully engineered and calculated for each part.



All epoxy suppliers sell fillers, such as a Cab-O-Sill, milled fibers, and Q-Cells.  These are useful on some shapes to make a paste to get good edges and corners.  Painted in corners, they help define small details, too.  A paste made with filler is useful to fix flaws that may appear in the final part, also.
