If we, Western Civilization, had started out with electric cars, and a century later someone came along with the idea of exploding little dollops of gasoline mixed with air to propel them, that person would be thought insane. Depending on price, the cost of energy to propel an electric car a given distance can be…

The Fukushima Alternative

On March 11th, 2011, a large earthquake caused a large tsunami in Japan, and the two historic events wrecked the Fukushima Daiichi nuclear power plant. The power plant had six boiling water reactors of the kind used around the world in many nuclear power plants. Three of the six reactors suffered a meltdown, and containment…

The Most Impressive Comeback Story You Haven’t Heard By Ross Chanin & Emilee Pierce If you read the tech press, you know the scoop: Google just bought Nest Labs (the maker of smart thermostats and smoke detectors) for $3.2 billion. For context, that’s more than three times the amount that Facebook paid for Instagram in…

James Hansen on Nuclear Power

James Hansen, the famous climate scientist and author of Storms of my Grandchildren, talks about the possible role of nuclear power in addressing climate change, and in particular, reducing the release of fossil carbon into the atmosphere. I think he is far to pessimistic on the use of solar and wind energy than he needs…

Waste to Energy Plants Are Good

When I was a kid, there was a strange looking garbage can in the back yard. It looked like a regular metal garbage cans (garbage cans were metal back in those days, before plastic was invented) but it was covered with round holes about one inch in diameter. It was also heavily corroded and lived…

City of Angels Will Dump Coal by 2025

Last February 17th, there was a big rally at the Los Angeles City Hall where people demanded action on climate change and an end to our reliance on fossil fuel. The city of Los Angeles gets 39% of its electricity from coal fired plants, so that would be hard. But today, we’ve learned that “…Los…

There will be a discussion on Climate Desk Live about this topic tomorrow, Feb 27th. Details and access to the event are HERE. Increasingly, the US Navy is leading the charge towards clean energy, which can in turn impact national security an even climate change. Through investments in biofuels, construction of a more energy-efficient fleet,…

A big step in improving the efficiency of photovoltaic cells in on the horizon. A paper published over the weekend in Nature Physics describes the ability of a substance called Graphene to convert a high percentage of the energy from sunlight into electricity. Graphene uses more of each photon’s energy, and a wider range of…

Not so fast … 85% of Americans want more funding for research renewable energy such as wind power. In Iowa, a state leading in wind energy production, 85% of voters view tax credits for wind production as positive. Also in Iowa, 57% of all voters would oppose a presidential candidate who wanted to end tax…

An American company, Altaeros Energies, recently launched a prototype helium-shelled wind turbine that can be used at high altitudes. While the test run took place at 350ft above ground, the ultimate goal is a height of 1,000ft. Tethers send the converted power back to the ground. Compared with traditional wind turbines, the prototype garners twice…
