Micro-housing for Veterans

“‘Never leave someone behind.’

That was our pledge in the military and in my time as a police officer. When you retire or move on, that doesn’t go away.”

In 2014, Donnie Davis got a phone call about a local campground in southern New Jersey that was up for sale. A crazy idea popped into his head. It would require a lot of money and hard work, but it had the potential to help countless neighbors and families. Donnie decided to take a leap of faith — and change the lives of his…

Good Intentions, Poor Results

The energy efficiency industry in California is tangled with regulation.

Without a doubt, there are many policies that have been successful. California’s strict building codes have reduced energy use per capita and are responsible for eliminating the need to build 15-20 new power plants over the last 30 years. This is a great result and job well done.

But there are also plenty of cases where…

Angry Air!

John Tooley said, “Air is like crooked rivers, crooked people, teenagers, and cheap labor.  It always seeks the path of least resistance.”  He didn’t say that Angry air is Noisy air.   Air doesn’t like being forced through corrugated, flexible ducting, pushed around corners, and made to force open dampers.  It resists being made to perform in a way that it doesn’t want to.  It takes more and more force as the resistance increases.  Air is just fine when you just let it move at will.  It can…
