Wind generators on cell phone towers — are solar panels too expensive?
Some cell phone towers alongside I-78 in NJ now have “windmills” on top. The diameter of the turbine is around 6 feet. They look much like the farm windmill generators in the 30-ties. With many blades. Not just the three as on modern day large scale wind turbines.
Questions:
1. Did I assume correctly, those are electrical generators? (Or are they possibly just “wind speed” and “weather conditions” measurement devices, operated by a company other than the cell phone operators?)
2. Why so many blades? I thought that was the issue with the old farm windmill generators, they were not as efficient.
3. Why windpower? I thought solar panels are the “in-thing”. (Are solar panels in fact too expensive to install and service? Do they need bigger back-up batteries, since they do not work at night?)

1. If they’re 6 foot in size they must be for electricity.
2.So they can be used in low wind.
3.Wind is cheaper and makes more power. Solar has good pr from people who know really nothing about it.
Size of th battery would most likely be the same seeing you can run out of wind just as long as you run out of light on rainy days.

LaplaceBeltrami Operator $70.1 High Quality Content by WIKIPEDIA articles In differential geometry, the Laplace operator, named after PierreSimon Laplace, can be generalized to operate on functions defined on surfaces in Euclidean space and, more generally, on Riemannian and pseudoRiemannian manifolds. This more general operator goes by the name LaplaceBeltrami operator, after Laplace and Eugenio Beltrami. Like the Laplacian, the LaplaceBeltrami operator is defined as the divergence of the gradient, and is a linear operator taking functions into functions. The operator can be extended to operate on tensors as the divergence of the covariant derivative. Alternatively, the operator can be generalized to operate on differential forms using the divergence and exterior derivative. The resulting operator is called the Laplacede Rham operator.

Transfer Operator $79.66 High Quality Content by WIKIPEDIA articles In mathematics, the transfer operator encodes information about an iterated map and is frequently used to study the behavior of dynamical systems, statistical mechanics, quantum chaos and fractals. The transfer operator is sometimes called the Ruelle operator, after David Ruelle, or the RuellePerronFrobenius operator in reference to the applicability of the FrobeniusPerron theorem to the determination of the eigenvalues of the operator.

Toeplitz Operator $62.13 PMHigh Quality Content by WIKIPEDIA articles In operator theory, a Toeplitz operator is the compression of a multiplication operator on the circle to the Hardy space.Let S1 be the circle, with the standard Lebesgue measure, and L2(S1) be the Hilbert space of squareintegrable functions. A bounded measurable function g on S1 defines a multiplication operator Mg on L2(S1). Let P be the projection from L2(S1) onto the Hardy space H2. The Toeplitz operator with symbol g is defined by T_g = P M_g vert_{H 2}, where means restriction. A bounded operator on H2 is Toeplitz if and only if its matrix representation, in the basis {zn, n 0}, has constant diagonal Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Operator Associativity $79.66 High Quality Content by WIKIPEDIA articles In programming languages and mathematical notation, the associativity (or fixity) of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses. Operators may be leftassociative, rightassociative or nonassociative. The associativity and precedence of an operator depends on the programming language in question. Consider the expression a b c. If the operator has left associativity, this expression would be interpreted as (a b) c and evaluated lefttoright. If the operator has right associativity, the expression would be interpreted as a (b c) and evaluated righttoleft. If the operator is nonassociative, the expression might be a syntax error, or it might have some special meaning. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Comma Operator $73.28 High Quality Content by WIKIPEDIA articles In the C and C++ programming languages, the comma operator (represented by the token, ) is a binary operator that evaluates its first operand and discards the result, it then evaluates the second operand and returns this value (and type). The comma operator has the lowest precedence of any C operator, and acts as a sequence point. The use of the comma token as an operator is distinct from its use in function calls and definitions, variable declarations, enum declarations, and similar constructs, where it acts as a separator.
