This alternator starts to charge my 48V battery bank at 120 rpm. At 200 rpm we generate just over 2000 Watts. It’s fairly exciting — it’s easy to maintain this level of power output with even the low grade wood we have around here. At this power level the alternator doesn’t hardly warm up at [...]
For a class project (PV Design, Appalachian State, Dr. Dennis Scanlin) I decided to try making a low cost PV tracker. Being able to follow the suns path through the sky can raise your system output considerably (30-50%), but the argon filled ones can be a bit pricey, and seem to be a bit unsteady [...]
SolarWall air heating system is a custom engineered solution containing many internal and external components.
It uses solar energy to heat and ventilate indoor spaces in new and retrofit applications, as well as to heat air for manufacturing process and agricultural crop drying applications. The system design is optimized to maximize energy delivery with a minimum [...]
Another form of ocean energy is called tidal energy. When tides comes into the shore, they can be trapped in reservoirs behind dams. Then when the tide drops, the water behind the dam can be let out just like in a regular hydroelectric power plant.Tidal energy has been used since about the 11th Century, [...]
Kinetic energy (movement) exists in the moving waves of the ocean. That energy can be used to power a turbine. In this simple example, to the right, the wave rises into a chamber. The rising water forces the air out of the chamber. The moving air spins a turbine which can turn a generator.
When [...]
Biodiesel energy is made from soybean oil and yellow grease, which is mainly comprised of oil leftover from restaurants that is then recycled and turned into usable oil.
Biodiesel fuel can be used on its own, or it can be combined with petroleum. Because it is often mixed with petroleum, biodiesel is often classified with a [...]
Biomass energy is renewable source of energy that is found in plants. Plants take energy from the sun in the process of photosynthesis and use it to produce and grow biomass. Biomass is a known product or material that is found in most living things. It can be animal material, bacteria, or plant materials. The [...]
Japanese company Genepax presents its eco-friendly car that runs on nothing but water.
The car has an energy generator that extracts hydrogen from water that is poured into the car’s tank. The generator then releases electrons that produce electric power to run the car. Genepax, the company that invented the technology, aims to collaborate with Japanese [...]
