Steven M. Johnson has some good ideas, but there have been others worth noting in TreeHugger.

Why turn your car into a living room when it can also be a kitchen?

It's reminiscent of some other crackpot ideas from the seventies.

An annual Toronto event is pretty utopian, as two major highways are closed to cars and given over to cyclists.

Steven M. Johnson beat the GrubHub by 25 years.

This gives the "spin cycle" a whole new meaning.

A test, on a trip from Toronto to Quebec City.

The total estimated population of the Javan rhinoceros in Vietnam was perhaps eight individuals just three years ago. Now WWF reports that there is one less of the beyond critically endangered rhinos in the Cat Tien

Last April, airport authorities became suspicious of a traveler arriving to LAX from Vietnam after noticing bird droppings on his socks and feathers peeking from the cuffs of his pants. A closer inspection of the man,

In addition to being one of the planet's most endangered primates, northern white-cheeked crested gibbons are among the most romantic -- and it's their love of the serenade which clued researchers to a significant discovery. Over

This long, deep house has a wonderful low tech vertical garden that anyone could maintain.

Christopher Mims describes how robots are changing manufacturing and eliminating jobs

Thanks to GRID Alternatives and Wells Fargo, more than 1000 US military veterans and active servicemen will be getting solar industry job training and job placement.

The Solar Training Network will work to build a diverse, qualified solar workforce to meet the needs of the solar revolution.

People often write of climate associated flooding, loss of agricultural productivity, spread of tropical disease, and so on. The City of Lahore, Pakistan is experiencing

As if melting Himalayan glaciers weren't enough to radically (and perhaps catastrophically) reshape water supply in South Asia, a new report from researchers at Purdue University shows that summer monsoons could be

The near-death of one of India's most distinguished scientists has halted work on a major hydroelectric dam in the Himalayas. Professor AD Agarwal, 77, former dean of the Indian Institute of Technology Delhi at Kanpur,

Adventurous, and eco-friendly, travelers often seek out off-beat lodging options, staying in yurts or on organic farms, both to soak up more local color and to avoid the

With all the recent brouhaha over inaccurate and since retracted statements in the 2007 IPCC climate change report about the speed with which Himalayan glaciers are melting, a recent series of posts over at China Dialogue is

$46 million is going to give students who do well their own solar power.

It's like that 1965 movie Crack in the World, where drilling for geothermal energy causes all kinds of problems. There are such high hopes for real geothermal power; there is a lot of heat down there that can vaporize water and run turbines.

The Google-funded research shows that there's 3 million megawatts of geothermal power, across the entire US, waiting to be tapped via enhanced geothermal techniques.

A former Nazi bunker located in Hamburg, Germany is about to get a full-scale makeover. The building, which looks like a giant LEGO, will supply 3,000 homes with heating and 1,000 of those with electricity, cutting 6,600 tons of CO2 per year.

Demand for lithium is growing very rapidly thanks to portable electronics and electric vehicles. What if we could get a lot of lithium cheaply, without building new mines?

A recently opened power plant in the Nevada desert uses two types of renewable energy.

This integrative technology keeps CO2 out of the atmosphere and makes geothermal energy widely available

Geothermal energy constantly gets overshadowed by other sources of clean energy, like wind and solar, because it's still more expensive. But with every passing year, it gets closer to its time in the spotlight.

Compared to New Zealand, we all have work to do.
