22 March 2017, Yale Climate Connections, Company turns piped water into electricity. To reach your tap, water flows through a network of pipes. One company is using the pressure in those pipes to create energy. Bergan French: “We take the excess pressure that would otherwise be thrown away, and we convert it into electricity.” That’s Nina Bergan French, CEO of Lucid Energy. Her company installs turbines inside gravity-fed water pipes. They provide energy without interrupting service. Bergan French: “It’s a whole pipe system with one or more turbines in it, with a generator sitting outside the pipe, connected to either the grid or a battery backup.” Unlike most hydropower, the system does not pose risks to wildlife or its habitat. And unlike solar and wind …Bergan French: “This technology works 24/7. If the water is flowing, we’re making electricity. It’s not dependent on day and night. It’s not dependent on the weather.” A pilot project in California powers street lights. And another in Oregon makes enough electricity to power about 100 homes. French says the company is working on making the turbines more efficient. She expects that they will have a commercially viable product ready for testing by the end of the year. The goal is to provide a source of renewable energy that can be easily integrated as cities upgrade their water pipes. Read More here
20 March 2017, The Guardian, Atlantic City and Miami Beach: two takes on tackling the rising waters. Sea level rise is making floods more common and as the New Jersey resort braces for the next Sandy, the well-heeled Florida city is throwing money at the problem. he Irish Pub near Atlantic City’s famed boardwalk doesn’t have any locks on the doors as it is open 24 hours a day. So when Hurricane Sandy crunched into what was once known as the Las Vegas of the east coast in 2012, some improvisation was needed. Regular drinkers helped slot a cork board through the frame of the door, wedging it shut and keeping out the surging seawater. The wild night, which severely damaged more than 320 homes and caused a week-long power blackout, was seen out by those taking shelter with the help of several bottles of Jameson. But Sandy was just the headline act among increasingly common flooding events that are gnawing away at the thin island upon which the city sits. Sandy, as devastating as it was, isn’t the greatest barometer because we have flash floods,” said Cathy Burke, who has run the Irish Pub since 1973. Burke, a gravelly voiced institution along the boardwalk, has hoarded treasures from Atlantic City’s zenith. The upstairs of the pub is replete with vintage furniture, gramophones and china dogs. “We can have floods at the drop of a hat,” Burke said. “Without even realizing we’re going to have them. It’ll be raining and within seconds you’ll see flooding in the street. You don’t read about it in the paper. You don’t hear about it on the radio or television. You just have water that just comes up and if you don’t have warning and move your car, you have water in the car.” These flooding events have increased seven-fold in Atlantic City since the 1950s, according to the National Oceanic and Atmospheric Administration, and are spurred by rainfall or simply a spring tide abetted by unhelpful gusts of wind. The casinos and boardwalk are protected on the ocean side by a network of beach dunes. But the western side of the city, where few tourists venture and poverty lingers, is more vulnerable. Several times a month water swells in the bay behind Absecon Island – the barrier strip dotted by the resorts of Atlantic City, Ventnor, Margate and Longport – and with nowhere to go can slosh into the streets, wrecking cars and stranding residents.
