Lead Recycling Threatened By Lithium-ion

The U.S. Society of Automotive Engineers (SAE) and the International Electrotechnical Committee (IEC) are proposing to develop standardized labels that are color-coded to allow for better identification between lead-acid and lithium-ion batteries.

United Airlines is flying on biofuels ... here's why that's a really big deal

Chelsea Harvey for The Washington Post:   On Friday, United Airlines will launch a new initiative that uses biofuel to help power flights running between Los Angeles and San Francisco, with eventual plans to expand to all flights operating out of LAX. It's the first time an American airline will begin using renewable fuel for regular commercial operations, and the occasion is part of a bigger movement when it comes to clean transportation in the U.S. The renewable fuel used to power United's planes will be coming from a Los Angeles refinery operated by AltAir Fuels, which is using the facility to produce both renewable jet fuel and diesel fuel using a technology developed by Honeywell UOP, a major supplier and technology licenser in the petroleum industry. Back in 2013, AltAir and United announced their partnership, in which United will purchase up to 15 million gallons of biofuel over a three-year period. Friday's launch will be the first application of that agreement. The flights will use a mixture of 30 percent biofuel and 70 percent traditional fuel, and United says that the biofuel will help reduce greenhouse gas emissions by about 60 percent compared with regular fuel.   Cont'd...

Interview with Michael Wiener of SolarRoofHook.com

In general, the installer just removes the roof piece, locates the rafters, drills pilot holes, fastens the product to the rafter, properly seals the penetration, and grinds the tile where the mount is located before placing the roof piece back over or around the mount.

Energy-Storage Startup LightSail Plots Long-Term Game Plan

Barbara Haislip for the Wall Street Journal:  Few industries are more daunting for entrepreneurs these days than clean energy. Developing the technology and hardware is expensive, and setbacks are common. Even if all goes well, getting a product to market can take a decade or more. Most venture-fund investors, meanwhile, want a quicker payout. Danielle Fong, co-founder and chief scientist of LightSail Energy, is trying to keep investors happy while working toward some ambitious clean-energy goals. Her company’s aim, she says, “is to produce the world’s cleanest and most economical energy-storage system” through a technology that uses compressed air to store energy from the grid. LightSail’s technology will do this more efficiently than other solutions, Ms. Fong says, by capturing some of the excess heat that comes when compressing air.  “Until now, this was wasted, reducing efficiency,” she says. Founded in 2009, Berkeley, Calif.-based LightSail has raised $70 million from several investors, including Bill Gates, Peter Thiel,Khosla Ventures and the French energy giant Total.   Cont'd...
