Rain Gardens – Turn Rain Into Beauty In Your Garden
Our rainy season will be here vey soon. Have you given any thought to how you might capture some of this critical resource that we seem to be increasingly short on? How about using it to enhance both the health and curb appeal of your garden? In our October 12, 2017 EGG meeting, Shelkie Tao will go over many details of taking advantage of our winter rains to bring more beauty to your garden. So jump out of bed, grab some breakfast, and join us in Saratoga for this interesting session with Shelkie! Read More
Wave Hello To Energy!
Is there value in using mechanisms along our seashore to extract energy? Are they going to interfere too much with the natural balance in the sea and aesthetic appeal of the seascape? Join us on October 05, 2017 and we will take a look at the pros and cons of using Wave Energy Conversion (WEC) to satisfy our demand of energy. We will investigate wave basics as well as the different types of Wave Energy Conversion mechanisms and what new designs are being developed. Join us for this interesting session! Read More
Equifax Security Breach Aftermath: Rescuing Your Green
It has been a painful two weeks since we were notified of the massive Equifax Data Breach. As I am doing, you are probably scampering around trying to secure and put safeguards in place to deal with this terrible breach. We thought it would be a good idea to pause our green thoughts for a moment and take a close look at what happened and what we should be doing to protect ourselves. Join us on September 28, 2017, at our next EGG meeting, for an important presentation by Mark Hoff to investigate and discuss where we go from here. Read More
Mid-September 2017 "Free For All"
Our speakers are taking a break and so now is the time to give everybody the opportunity to discuss, debate, and get educated on all the green and clean issues that we are faced with today. In our September 21, 2017 meeting, we are going to start off by addressing the CA WaterFix/Delta Tunnels Project. Where we go from there depends on what else people want to talk about. Join us and leave our meeting well informed and with an itch to do something about some of the problems we are facing! Read More

Behind every advancement in the areas of renewable energy and energy management, are some underlying technologies which help make those advancements possible. The IEEE 1588 Precision Time Protocol is one of those underlying technologies which is helping to make the Smart Grid a reality. This presentation will provide an overview of this technology and some of its uses in the Smart Grid.

Rainsavers recently completed a job in Mountain View, California whose owner built a home that uses very little municipal water and has native Santa Clara County plants, grasses and fruit trees. Rainsavers installs rain barrels, tanks and complete systems for residential, commercial and public facilities.
The homeowner built the home with a grey water recycling system, sheet metal roofing material, a solar hot water heating system, a “wetland” leach field where the grey water is diverted and a Rain Water harvesting system.
The owner also had a nine thousand gallon underground cistern installed as the home was built to store the rainwater from the roof. One of the goals and mandates coming from state and local governments is to greatly reduce runoff from around the bay area. All the gutter downspouts are routed to the tank. The water collected is tied to her drip irrigation system and used on the landscape. The tank overflow is directed to a rain garden where the water seeps back into the ground.
Rainsavers was hired to install the pump, pressure tank, electronic valves, controller, PVC conduits and electrical supply for the system on her property.
The first picture shows the smooth concrete siding, the metal roof, manhole access to the tank and the wetland field on the left side.
The drip system can be automatically switched from municipal water to the rain water system depending on storage levels, via a three-way electronic control valve.
The second picture shows the pump, pressure tank, controller and electric panel. A pressure tank has 20-40 pounds of air pressure to prevent the pump from cycling on/off as the systems is used. The controller monitors the water level in the tank, and it can activate system flush, backup, transfers, drain and service reminders.
On November 13, 2012, MIT/Stanford Venture Lab (VLAB) sponsored “Grid Energy Storage: Beyond Batteries”, a panel event to discuss grid-scale energy storage. After treating the audience of about 300 investors, entrepreneurs, technologists and thought leaders to a short harmonica solo, Eric Wesoff from Greentech Media proceeded to outline the landscape around grid-scale energy storage and moderate the panel around future directions in grid-scale energy storage.

Wesoff overviewed current technologies, the complicated value chain which generates and delivers energy to end users, the cleantech investment climate, and the environmental /government mandated need for clean, renewable energy which can only be enabled by grid-scale energy storage.
Currently, grid scale energy storage is dominated by pumped hydro. “For grid applications, it’s all about cost per kilowatt hour” said, Abe Yokell, panelist and Partner at Rockport Capital Partners who foresees grid-scale energy storage for certain, specific use cases such as where local energy storage in dense urban environments is less expensive than running in new utility lines. Philip Gleckman, CTO of Areva Solar agreed “Grid Storage with batteries is not inevitable…Thermal storage is available costing one tenth of the best battery technology. Justin Raade, CEO of Halotechnics, Inc described how his company is working on grid-scale thermal storage as low as $25/kw-hr.
Indeed, two grid-scale energy storage companies were represented on the panel. Lightsail Energy of Berkeley, CA and Aquion Energy of Pittsburgh, PA shared their experiences as start-ups entering a heavily regulated, highly fractioned, risk averse environment.

Rounding out the panel was Haresh Kamath, Sr. Project Manager for EPRI. “While American utilities are greatly incented to “KTLO – Keep the Lights On” which has led to risk averse investing, Kamath & Rastler have described 10 specific business cases for grid-scale energy storage which have attracted attention from the venture capital and investment community. Kamath noted that for certain off-grid applications, the newer energy storage technologies, when paired with solar, have the potential to “leapfrog” the current grid which many have observed to be little changed over the past 100 years.
Mike Lee, Financial Advisor, on why Morgan Stanley sponsored the panel, “We like sponsoring these sorts of events in order to bring people together to facilitate growth in this community.” Another perspective was offered by Laurie Manning, volunteer with the MIT/Stanford Venture Lab “We have to look beyond our current economic crisis to greater environmental issues. Superstorm Sandy showed this. We need greater urgency before it’s too late.”
