Home Power Optimization: the REbus™Microgrid

Home Power: Meet the REbus™ microgrid!

Run your decentralized Renewables efficiently and put them to use flexibly. From solar PV generation to micro wind turbines and battery storage, include even electrical vehicle charging and integration!

A REbus™ microgrid is a flexible energy network operating alongside the existing AC distribution network. Click http://wwwminiwindsystems.com/ for some specs and details. REbus™ is the ideal standard for connecting different sources of clean energy, including solar modules and small wind turbines, into an integrated hybrid system. The REbus™ standard makes it possible to more efficiently store clean energy produced on-site, and is ideal for charging electric vehicles quickly. The performance of each product on a REbus™ microgrid is easily monitored through a built-in communication layer.

The REbus™ DC microgrid is a great solution for anyone looking to generate clean renewable energy whether on-grid or off-grid. It easily and efficiently integrates PV, wind and other alternative energy sources, allowing a single inexpensive inverter to connect to the utility grid. The communications link gives renewable energy consumers instant access to data from each of their renewable energy devices for monitoring or diagnosis.

Converting the power coming from your renewable energy source to a REbus™ microgrid is significantly more efficient than the same conversion to a convential AC grid. Plus, the high voltage DC transmission means lower current in the connecting wires which improves the power transfer efficiency.

Because of the reduced electrical current in the wires, the cost of wiring is reduced.

The integrated power line carrier communication scheme eliminates the need for expensive and unreliable wireless communications. In todays insanely wireless world, it is a good idea to use wired communications instead of Wi-Fi. Wired communications provide increase security, less EMF radiation and less exposure of humans, decreasing adverse health effects of EMFs. Optional Ethernet communications are also available.

The overall efficiency and flexibility of the REbus™ microgrid system is significant, reducing cost of de-centralized Renewables generation and further increasing acceptability and potential of these technologies by improved usability.

 

Low-Energy Lamps: What’s Right, What’s Wrong?

When it comes to low-energy lamps, it is often confusing to know what’s right and what’s wrong: too much irritating advertising, sometimes unwarranted claims of “eco-friendliness”, price wars that can distort the picture. In order for you to make informed decisions, we would like to help you educate yourself about energy-saving lamps.

First of all, it is important to point out that CFLs are NOT the way to go: every tube including the ones contained in CFLs leave poisenuos heavy metals when discarded (like mercury contaminating drinking water supplies). CFLs also have a high-current “ignition” unit that emits Electromagnetic Fields or EMFs that are potentially harmful to your health. Also, CFLs are roughly 30% less energy-efficient than their more recent LED counterparts. The last point alone partly defies the idea of “eneergz efficiency” for CFLs.

LED (light-emitting diodes) have entered the race for lighting our buildings a lot later but have been around for some time now. Even if their price tag usually shows higher upfront prices, these are amortized by LED-based lamps’ better efficiency. An old 60 W light bulb can be replaced with LED lams of just 4 W, therefore using just 1/15th of power. So it’s a good idea to pay a few pennies more upfront and get LED lamps right away that last longer (25-30 years, almost like a good mini wind turbine). The bottom line is that LED lamps surpass those low-energy CFLs and can total 90%-94% in energy savings and pay for themselves many times over, despite their higher initial purchasing cost.

Also, LEDs don’t wear out from heavy turning on and off and are thus suitable for all kinds of rooms including the ones you enter for just a few moments before switching the light off again. Remember, those strobe lights for bikes use LEDs without any wear and tear.

Add to this the absence of any harmful EMFs and the peace of mind that you may use them even at less than 5 ft from your head, and the LED is the clear overall winner for your lighting needs.

Get Some German Engineering (Not Just for Your Driveway)

A revolutionary design, patented blades and an extremely high output ratio — these are the main features of a micro wind turbine truly “Made in Germany” but without the associated cost of most of the VW models people put in their driveways these days.

The BreezeBreaker 500 is under 5 ft (1.5 m) in diameter and costs under $1500. Developed by a 19-year old inventor from Hannover, Germany, this turbine has the lowest weight-to-output ratio in the world and undercuts Japan’s Zephyr Airdolphin Z1000-25 and Airdolphin GTO™ “next generation” models by roughly one third.

It did not take very long for the “next generation” to start looking like a rather old one: BreezeBreaker 500 by 19 years old Fritz Unger does not only sport a sensational weight-to-output ratio (just 11.875 grams per Watt of rated power) but also makes clever use of rotor physics: 2-blade designs are generally far superior to more blades as 2-blade rotors reduce blade turbulence and suffer significantly less wind energy loss.
