http://interestingengineering.com/really-take-run-world-off-renewable-energy/ With electric power establishing itself even further into our modern society, generating it is becoming an even more complex issue. As we seek to find a sustainable power source, we are naturally drawn to the thought of renewable energy. However, the question remains, what would it really take to run the world completely off of →
Low voltage DC systems need suitable connectors. Different proprietary connectors are available, but usually with them problem is their price and availability. Traditional lighter plug as used in cars is awful in many ways. Some applications use XLR connectors successfully, with the downside that you can accidentally plug mic to such outlet. One thing I have sometimes seen in Finnish electrical installations →
http://www.edn.com/design/power-management/4458294/Using-a-supercapacitor-for-power-management-and-energy-storage-with-a-small-solar-cell–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells. Depending on the light level, whether indoors or out, small solar cells may deliver →
This is 150W 12V DC to 230V 50 Hz AC conveter designed to be used in car. It failed few days ago when powering a laptop. Let’s take a look what is inside. Closer look. Here is DC power input filtering.. looks as quite ugly late add-on to design.. More circuit board details. On the →

Power-factor correction allows the input current to continuously flow, reduces the peak input current, and reduces the energy loss in the power supply, thus improving its operation →

http://spectrum.ieee.org/energy/renewables/nanogrids-microgrids-and-big-data-the-future-of-the-power-grid The power grid’s interlocking technological, economic, and regulatory underpinnings were established about a century ago and have undergone only minimal disruption in the decades since. But now the industry is facing massive change. →

When the lights flicker at home, it’s an annoyance. But when power is disturbed at a factory, it →
