Powerselect alternator generator#
This machine was used as a generator producing 3,000-volt, 133-hertz, single-phase AC, and an identical machine 3 miles (4.8 km) away was used as an AC motor. In what is considered the first industrial use of alternating current in 1891, workmen pose with a Westinghouse alternator at the Ames Hydroelectric Generating Plant. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. Alternators in power stations driven by steam turbines are called turbo-alternators. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.Īn alternator that uses a permanent magnet for its magnetic field is called a magneto. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Īn alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. While this product may be very good and worthy of a donation, I personally believe that their are far too many 'Find a File' apps available right now and that it is time that some of them become mature products.Alternators made in 1909 by Ganz Works in the power generating hall of a Russian hydroelectric station (photograph by Prokudin-Gorsky, 1911).
Powerselect alternator mac#
I can only hope that the developers who are talented and creative will focus their future efforts on adding expanded features to their 'find' products or concentrate their efforts into other Mac Apps where the interest and demand for better products is of user interest. In some respects I would like to apologize to the developer of Power Select, not for seemly casting aspersions on his product, which is not the case, but for using his latest release as a soapbox to make comments about all the wide variety of products that essentially do the same thing, abet in slightly different ways, but do little else. Yes, it is expensive for a utility, but for me it is an extremely good value with a long pedigree. For me it duplicates or replaces an absolutely huge number of other file management utilities. It also has an immense number of other features such as locating invisible and duplicate files. It finds everything, including invisible files and files buried in the core of the system. Spotlight can also lock onto comments placed in a files 'Get Info' window which can contain only key words.įor more comprehensive file management I have never found anything to compare with File Buddy. A little time spent with it, learning how it wotks with key combinations (Cmd, Opt, Cntr, Shift) yield some amazing results.
Personally I like Apple's Spotlight for simple searches for files and as a fast App launcher (using 10.8).
Convenience and ease of use is one of those things, like speaker selection, where a high degree of personal judgement comes into play. While the price may be correct for this product unfortunately it is just one of many apps, some free, and some commercial that search for a file on your hard drive and do little to nothing more.
