Carnot Efficiency 2: Reversing the Cycle Seeing how we can scale and or reverse a Carnot Engine (to make a refrigerator)
27. Deadweight Loss and The Efficiency Criterion This video demonstrates the concept of deadweight loss as an application of the efficiency criterion. I consider two cases: a per-unit tax, and a per-unit subsidy. Why does a per-unit tax create deadweight loss, and how do I identify it on a supply and demand graph? Why does a per-unit subsidy create DWL even though it is a "negative tax"? This video answers these questions using the efficiency criterion. *Pareto efficiency is a different concept than the one employed in this video, but it is related. I may address this relationship in a future video.

Swimming - Freestyle - Discovering Efficiency Step 1 When many swimmers begin the quest to develop the most efficient freestyle, the initial focus seems to be on a low stroke count. However, the lowest stroke count is far from being the most efficient stroke.
Leatherman Squirt P4: Sub-compact Efficiency The Squirt can handle most everyday tool taskings. Other Squirt models, as of 2008, include the E4 (wire strippers) and the S4 (scissors version). For me, the P4 is the most useful with it tiny pliers, pen blade, flat bladed drivers, file (cool!) and wonderful punch awl (all MTs should have this!). But this 2.0 oz sub-compact MT does have some limitations: don't expect the pliers to have great metal cutting or torque capabilities. Blame Isaac Newton as it's just a function of the Squirt's tiny size. As far as tiny MTs go, this is the best.
Swimming - Freestyle - Discovering Efficiency Step 2 In our first of a short series on discovering efficiency, we started with counting strokes. With that as our basis, we're going to add a simple step to that focus point... speed. Understanding that speed will be calculated with our standard measurement in swimming, time.

Excel Formula Efficiency 1: SUMPRODUCT function 12 Examples Learn about the basics of SUMPRODUCT function and why some people use double negative and why other use times one. Learn theses important points: 1.When using the SUMPRODUCT function and multiple criteria, see how multiplying by one is more flexible than the double negative 2.When using the SUMPRODUCT function and multiple criteria, see how using double negative will not yield an error when text is in the data range but multiplying by one will yield an error (double negative can handle text) 3.When using the SUMPRODUCT function and multiple criteria, see how using double negative is sometimes faster than multiplying by one Learn how to speed up slow calculating spreadsheets with formulas that calculate faster. See many methods to speed up your spreadsheet decrease the amount of time it takes for the formulas to calculate. The tricks you see are from a White Paper called Improving Performance in Excel 2007. In this video series you will see tricks for both Excel 2003 and Excel 2007. Many of the large formulas in this series involve multi-conditional multiple criteria calculations that slow down the spreadsheet (worksheet, workbook).
Efficiency Without Compromise With energy consumption and costs rising, energy efficiency has become a major concern for data center operators and managers, but energy represents only a slice of data center lifecycle costs. The challenge is to lower costs while maintaining or improving availability. Emerson Network Power is helping organizations meet this challenge through Efficiency Without Compromise, which provides a flexible path for optimizing data center infrastructure design, operating and management efficiencies, all with an eye toward availability.

Electricity use and efficiency of servers and data centers: A review of recen... Google Tech Talks December, 4 2007 The Internet economy depends on a reliable computing infrastructure. While earlier reports of information technology using vast amounts all electricity were grossly exaggerated, these facilities still use electricity, and this use is growing rapidly. Recent ***ysis indicates that data center electricity use in both the US and the world roughly doubled from 2000 to 2005, and this growth is expected to slow only modestly over the following five years. Growth of this magnitude represents a substantial business opportunity for technology companies. This talk will describe results of recent work ***yzing trends in total data center power use and how this growth varies by major world region. It will also explore the misplaced incentives and institutional failures that impede data center efficiency investments on a large scale. Finally, it will describe business, government, and research efforts to improve efficiency in these mission critical facilities, including recent work by the Energy Star program to promote server and data center efficiency.

Composite Materials Improve Efficiency Research projects from the University of Bath and the University of Plymouth demonstrate that composite materials are being used to work towards a more efficient future. For example, composites are vital for the aerospace industry where wings can be constructed to change shape in flight, making better use of flying conditions and drastically improving fuel efficiency. Also, in the renewable energy sector, composites are essential for the manufacture of turbine blades which need to be light, strong and durable. From the creation of renewable energy to the next generation of air travel, composites have the ability to transform our world.

BASF Video: Energy efficiency -- The World in 2030 Energy efficiency is the most important single future source of energy to supply the growing energy demand and to protect the climate. Being energy efficient in industry, mobility and housing will offer the biggest potential to use energy more efficient. Just through energy efficiency and with already existing technologies it's possible to curb our predicted increasing global energy demand and thus the CO2-emissions by the year 2030 significantly. In this special video edition of our podcast "Chemistry of Innovations" you will learn how energy efficiency helps to protect the climate.

Fallkniven A1: Compact Efficiency The A1 is just 14 oz but sports a nearly 1/4" thick blade. From my other "clinic" videos, I've demonstrated how such a thicker blade makes wilderness tasks easier, expending less energy. This is a huge advantage of this compact survival knife that few others possess. Other great features of the A1 include: laminated VG10 steel that will serve well in high moisture areas (and CeraCoated in black), a comfortable handle, full tang that can deliver defensive impacts, a convex grind, a good Kydex (now Zytel) sheath, and a reasonably price for such a high quality blade. This is the type of knife that disproves the oft-heard custom knife maker criticism that says production blades suck. A limitation of the design is its 6.3" blade which for me is on the short side for a wilderness blade. However often weight and size are very important and our system needs will prevent carrying a larger, heavier blade. In those situations this Fallkniven A1 is ideal and it will serve admirably as both a wilderness or tactical fixed blade. Improvements could include a quick detach method for the sheath, a longer handle (by just 1/2"), and maybe one day a full flat grind :-). Also please NOTE that I had reports on the brittleness of this laminated VG1 steel and ("mtbaddict" has his A1's tip break off) it seems you'll trade off some toughness for increased rust resistance. Still, the A1 is a capable blade and compact in dimensions, that can serve you well in the woods. SAFETY NOTE: These videos ...
