Yes! I can now slack off with 100% more efficiency!
2008-06-24 08:14:00 Woo Hoo! My job just got a billion times easier.My day job, as many of you know, is being a lawyer. When I'm not blogging, I sit in my office and I sue people. Suing people is not the glamorous, crazy, dramatic world that you'd picture if you've watched Law & Order or Tom Cruise's life. It's mostly a lot of paperwork. A lawyer's life boils down to piles and piles of paper, in folders and envelopes and boxes and on my desk and on every other lawyer's desk, too.Those papers are legal forms. They range, in my practice, from complaints (the document that gets a lawsuit going) to answers (the document that keeps it going) to settlement forms and releases (the forms that end lawsuits and result in my clients getting lots and lots of money) to the hundreds of spinoff documents that are created in a busy law practice: deeds, security agreements, promissory notes, leases, marital property agreements, and more.Lots of my time is, as a result of that, creating and modifying document...

92nd Carnival of Real Estate - All About Efficiency
2008-05-27 15:30:00 Welcome to the 92nd Carnival of Real Estate. I was asked to host on short notice and given this was a holiday weekend known for kicking off the summer driving season, I thought the theme should revolve around efficiency in real estate blog posts.With gas at all time highs and with no sign of dropping, efficiency is going to become important for all of us.Given the theme, I thought I would assign a vehicle ranking to the selected posts. There were a lot of great posts but choosing "winners" based on efficiency of making the point instead of content or grammar or even the subject removed any singular victor.Please congratulate the top group - the Tesla Roadsters that made their points clearly and concisely.

The Weekly Carboholic: boosting energy efficiency is hard to do
2008-05-14 22:16:00 Energy efficiency is tricky. You might think that increasing energy efficiency would be a no-brainer, since it usually pays for itself, improves the reliability of electrical transmission systems, reduces the number of power plants that need to be built, and reduces greenhouse gas (GHG) emissions. You’d be wrong. And last week, The Economist had a great overview as to why improving energy efficiency is so difficult. And according to the article, the reasons that energy efficiency gains aren’t metaphorically exploding all over the place come down to the intersections of these three areas: prices, markets, and governments. Price affects energy efficiency in at least two ways. The first is that energy efficient products almost always cost more to purchase, and so the up-front costs that consumers see cause “sticker shock”. This is obvious when you compare the price of a compact florescent lightbulb to that of an incandescent - the CFL costs a lot more even...

Efficiency
2008-05-03 11:15:00 I was flicking through a female fitness magazine recently looking at the usual articles produced for women. 'Tone those flabby arms', ' celebrity body' etc etc. When reading a calorie burning article I was amused to find that one of the benefits they had done was actually something that I would consider a negative.Something like this. . ."Cardio training will make the body more efficient and burning fat and calories!"Efficiency is a good thing, for example, with your car. If you drive 100 miles and it takes £20 pound of petrol then your wife takes her car out and goes the same distance but needs £30 of petrol then your car would be classed as more efficient. You cover more distance with less fuel.If you are a marathon runner then again, like the car, efficiency is a good thing. You want to be using a tiny amount of fuel to cover the furthest distance possible without having to load up on extra nutrients before or during the race.Efficiency with fat loss - We can see how effici...

Light efficiency lights up Orion Energy (OESX)
2008-04-29 07:00:00 "The US spends about $1 trillion per year on energy and it is estimated that advanced efficiency systems could reduce that energy bill by as much as 25% to 50%," explains emerging growth stock expert Toby Smith (http://www.thestockadvisors.co-m/ccount/click.php?id=1963). The editor of ChangeWave Investing (http://www.thestockadvisors.co-m/ccount/click.php?id=1963) says, "Orion Energy Systems (http://www.thestockadvisors.co-m/quote.htm?sym=oesx) (NASDAQ: OESX (http://www.thestockadvisors.co-m/quote.htm?sym=oesx)), a pure play in energy management system, is a recently public company that is still flying well under Wall Street's radar.""Electricity prices in the US are rising and there is a frightening dearth of new power plants coming online to meet demand for the coming decade.
