Massachusetts Lawmaker Pushes Water Power

Tuesday, July 26th, 2011

State Rep. James Cantwell, D-Marshfield, wants the state to encourage research and investment in hydrokinetics – the harnessing of energy from moving water – by allowing private companies and municipalities to sell back any energy they create through this technology to utility companies.

Researchers are working on devices that harness energy from the ocean’s tides and waves, as well as from upland rivers and streams. Work is underway to develop small devices that could attach to piers, docks, marinas or breakwaters to take advantage of the energy in smaller waves hitting fixed structures up and down the coast. Most would remain under the water or look like buoys, blending in with other moorings, and not be visible to the public. But without the ability to sell back energy, MacDonald said, there may not be a lot of interest.

Covered Bridges to Trade Cedar-shingle Roofs for Metal Tops

Tuesday, July 26th, 2011

Some covered bridges in Lancaster County, Pennsylvania are going to take on a new look. Well, not a totally new look, but one from a different time in their histories. Plans are to replace the cedar-shingle roofs for six county-owned covered bridges with metal roofs.

The Alternative Energy Fallacy

Monday, July 18th, 2011

Alternative energy investments often make sense for an individual homeowner; however, well-known investor advisory service “The Motley Fool” explains that the idea that widespread deployments of wind turbines, solar panels, and electric vehicles will slash hydrocarbon consumption and give us a greener planet is flawed. These technologies are heavy users of industrial metals. Any significant diversion of the production of those metals from current uses would result in their prices increasing faster than fossil fuels prices.
