In many areas of the world Air Conditioners have become essential electric appliances today. However, AC consumes a lot of energy, as I found out after moving to Indiana from the UK. I was too generous with the whole-house cooling...
Sun Tracking – Is it worth it for solar panels?
Sadly, solar panels are inherently inefficient. The most efficient are the monocrystalline type, which can reach 21% efficiency.
This means that for every 1000 watts of the sun’s ene...

One of the first design options – trolling motor mounted at the rear
I got the boating bug later on in life and so I bought an inflatable kayak. I quickly found that the idea was nice but paddling a canoe for longer than 20 minute...
Geothermal energy is a renewable, sustainable resource with many advantages and few disadvantages. Geothermal energy comes from inside the earth and the higher temperatures are found at lower depths, due to the temperature gradien...
Yes, geothermal energy can be used to power vehicles, in a roundabout way. When talking about geothermal energy, it simply refers to the heat energy generated by the earth’s internal forces, which makes its way to the surfaces. T...
What are the 5 main uses of geothermal energy?
8 uses of geothermal energy include:
Generating electricity
Home heating and cooling using ground-source heat-pumps
Heating greenhouses directly

Back in the 70s solar thermal heating was all the rage. That’s to say, it was very cool but in many Western countries people needed a little convincing.
The systems often didn’t look conventional enough for the average home-owner...
Are solar panels legit or a ripoff?
Are solar panels a ripoff or are they worth it?
A ripoff is defined as a theft, cheat or swindle. In the case of solar, it would suggest that solar panel manufacturers are knowingly selling prod...
How to work out how long a 100Ah battery will last
As a general rule, a 100Ah deep-cycle lead-acid battery discharged to 50% will run a 50 watt load for 12 hours, a 200 watt load for 3 hours and a 400 watt load for 1.5 hours. For...
It’s natural to assume that the question arises from concerns about the total weight of a solar panel array and the impact on the average home roof. Although becoming more and more common, house roofs are not the only place solar...
