The present invention relates to a support structure of hydrokinetic electric power plants, designed for converting the kinetic energy of unidirectional and invertible water flow into electric energy. In particular, it serves as an underwater structuring support girder of hydrokinetic turbines in rivers, as well as in tidal water flows. The advantages of the support structure are that due to the significantly decreased spaces between the shafts of the horizontal axial turbines, which it supports, the entire structure becomes more compact, lighter, and cheaper, while at the same time the turbines work in a more energy efficient way

The Best & Worst Oil Filter Made Today -13 Oil Filter Comparison



Views:30709|Rating:4.71|View Time:21:24Minutes|Likes:777|Dislikes:47
I cut open 13 oil filters to compare who is the best. Five of the oil filters were for conventional oil and the other eight filters were for synthetic oil. These are the brands of oil filters I cut open: Mobile1, Fram, STP, K&N, Wix, Bosch, Mopar, Motorcraft, AC Delco, and Supertech. This is an Ultimate Oil Filter Challenge, conventional vs synthetic oil filters. This is the best oil filter comparison I have done. Remember an OEM filter is always recommended by the dealer.
