Small-scale micro hydro power is both an efficient and reliable form of energy, most of the time. However, there are certain disadvantages that should be considered before constructing a small hydro power system. It is crucial to have a grasp of the potential energy benefits as well as the limitations of hydro technology. There are […]

These walls systems are all solid walls made out of dense materials, of which the modern Brick, Block and poured concrete walls are the most common variety.

You can make biogas energy with a DIY methane generator. Producing methane from manure using your own small scale waste to energy biogas digester is feasible for many small farms. What is Biogas Energy? Biogas energy is fueled by burning methane produced by the decomposition of organic wastes. Methane is a gas chemically CH4. It […]

You can get much bigger inverters on 24V or 48V than 12V. There are a number advantages in opting for a higher DC supply voltage. – For any given load, half the DC current and losses are down by ¼. Reduced fire risk.– Better input regulation. 0.5v line drop at 12v = 4.6% supply drop […]
