Cost-efficient Solution for Already Paved Parking Lots
The construction of parking lots is a very intensive exercise in every form. It involves a lot of heavy work and a lot of concrete as well. As is known, concrete hardens when it dries up and a large amount of prodding will get it damaged. Repairs may not leave the same smooth pavements and structures though. Parking lots always require lights because cars usually remain parked for long hours and may even be picked when it is already dark. It is therefore very important to make sure that the lights are installed....

Lower energy prices: Now you see them, now you don’t
When combined with efficiency, solar homes can achieve ‘net zero’ – they consume no more energy than they produce. It is likely we will see a growing number of net zero homes built as more states reach what is called ‘grid parity’ – the cost of solar energy becomes no higher than the power we buy from our utility. Industry insiders say that about a dozen states already have reached this goal.This is all good news. But at some point – maybe soon – the laws of supply and demand kick in, creating an odd dilemma for...

Introduction: In this process, vacuum extraction is used to remove contaminants from soils. After condensation, contaminants are mixed with a semiconductor catalyst such (e.g., titanium dioxide), and fed through a reactor which is illuminated by sunlight. Ultraviolet light activates the catalyst, which results in the formation of reactive chemicals known as `radicals`. These radicals are powerful oxidizers that break down the contaminants into non-toxic by-products such as carbon dioxide and water. A big...
