An overview of heat solar collectors.

Solar Energy Concepts

In the last post, “Where is the biggest bang for the buck in solar energy?” , I hope the data was convincing that the best place to use your time and money is toward heating your house and possibly the hot water you use. Tonight’s post is going to work from

Where is the biggest bang for the buck in solar energy?

Solar Energy Concepts

Tonight I thought I would start pointing the direction we will be going toward solar energy. Like in all projects the first thing to determine is where do we want to go. I am going to make the first assumption. We want to use our money in the most effective way

Efficiency and Effectiveness and Solar Energy.

Tonight’s post was intended to kick-off a discussion about solar energy, but as I was formulating how I was going to present it I kept running into a word … efficiency. I know the thermodynamic use of the term very well, but we often throw the word around to mean lots of other things. That

Short term energy storage, time delays, and oscillations.

We are quickly getting toward the end of our talk the theory of the thermistor circuit and will soon move that into construction. While construction is interesting, it is tough to create frequent posts of interesting content, so we are very soon going to move into some energy storage components. In electricity those are inductors

Voltage Regulation and Power Loss

Real PS & Load

This is one of those posts that is this hard of me to categorize and actually even to give a title because there is so much to say about so little. However, it is very important for several reasons. First, we will be talking about energy conservation. Second, it is

Energy Returned on Energy Invested, EROEI.

Balance

People sometimes refer to this as the energy balance. When we say we balance an equation or balance the books or balance just about anything we often think of a scale like that I posted here. However, often what we are really really interested in is “tipping the scales” in our favor. That

Episode 49 – Some more about heat radiation

In this episode I talk about a lot of general things and specifically about heat radiation.

I kind of went all over the road in this episode and started with a rant and funny story about the divisions happening among people here in the US and actually the rest of the world.

I did get

Episode 048 – Heat ,Thermodynamics, and Insulation – Part 3

5 TO 1 FT DIA

In this episode we review the difference between heat and temperature, state the laws of thermodynamics and how heat is transferred and then finally move on to insulation.

To further explain the difference between heat and temperature, I make the analogy of two tanks as show in the following two pictures. In the first picture

Episode 047 – Heat ,Thermodynamics, and Insulation.

This episode is primarily dedicated to heat and heat transfer. Building upon the previous episode the concept of heat and temperature are discussed some more. Using a water analogy, heat is similar to the volume of water in a tank and temperature is similar to the height of the top of the water in that

Episode 46 – Energy – The Basics

storm-lightning-bolt-md

In this episode I talk about the definitions of energy, work, an power. This episode was created because I found that I needed to lay a foundation before I talked about insulation and the conservation of energy. We often use the words power and energy interchangeably and that is incorrect. Energy is the ability to
