Tap into a good idea.

A poster for the Tap Project that will appear in Chicago, created by Energy BBDO.Water is a valuable commodity. Here on the West Coast drinkable water is easy to a take for granted. That is why this New York pay for your tap water initiative caught my eye. Beginning Sunday, March 16 through Saturday, March 22, over 300 New York based restaurants will invite their customers to donate a minimum of $1 for the tap water they would normally get for free.

Trash Based Bio Fuels

Aron recently blogged about the issue related to corn biofuels. Meanwhile, BlueFire Ethanol, a company based in California, sees promise in converting some trash into usable fuels.

The remains of plants processed for human purposes molder in landfills across the world. Whether waste paper or raked leaves, the plant remnants still contain cellulose, a sugar in greenery that bonds with the chemical compound lignin to furnish a plant’s structure. Microbes living in the landfills break down this cellulose into methane….

BlueFire estimates 40 billion gallons of cellulosic ethanol could be produced from plant waste destined for the landfill, providing as much as one third of all U.S. transportation fuel needs.

And, if other forms of waste, such as the stalks of corn plants (corn stover) or the remnants of timber harvest are included, Klann [Arnold Klann, BlueFire's president] says, “we have enough feedstock in the U.S. to offset 70 percent of the oil import.”

No corny solutions.

Alternative fuels are becoming big business as peak oil looms on the horizon. Unfortunately, it looks like corn is not the answer.

The rush to grow biofuel crops — widely embraced as part of the solution to global warming — is actually increasing greenhouse gas emissions rather than reducing them, according to two studies published Thursday in the journal Science.

….

The analysis calculated that a U.S. cornfield devoted to producing ethanol would have to be farmed for 167 years before it would begin to achieve a net reduction in emissions.

“Any biofuel that uses productive land is going to create more greenhouse gas emissions than it saves,” said Timothy Searchinger, a researcher at the Woodrow Wilson School of Public and International Affairs at Princeton University and the study’s lead author.

The studies prompted 10 prominent ecologists and environmental biologists to write to President Bush and congressional leaders Thursday, urging new policy “that ensures biofuels are not produced on productive forests, grassland or cropland.”
