Recently the Cleantech Group, with the assistance of an advisory panel of corporate executives, sat down to decide upon the third annual Global Cleantech 100: the hundred "most promising and innovative" clean technology companies of 2011. The listed companies span a range of industries, and though solar energy firms, chemical recyclers, LED manufacturers and energy-monitoring software programmers certainly aren't under-represented, many companies in the hundred are defined by a single product or idea. Gizmag scoured the Cleantech 100 to find what we thought were the ten most innovative companies.  Read More

Canadian Zoltan Bod is a self-proclaimed "car and performance nut" who has built his very own, very efficient, 151 mpg (1.56 L/100 km) concept car. Dubbed Zoleco (which merges part of Bod's name with the word "eco"), it is designed with ergonomic considerations and seats up to four passengers comfortably. It also features a teardrop body shape and a three-cylinder turbocharged gasoline engine, along with thermal and braking energy recovery technologies, that conserve as much energy as possible. The result is a sporty and eco-friendly car that we're told is fun to drive.  Read More

If you really want to minimize the amount of toxins that you put into the environment, use rechargeable batteries. Disposable and rechargeable batteries can contain heavy metals such as mercury, lead, and cadmium, and with an estimated 3 billion batteries a year being discarded in the U.S. alone, the sometimes small amounts in each battery can really add up. Using rechargeables greatly reduces the number of batteries entering landfills, but many people don't bother buying them, or the chargers that they require. That's where earthCell batteries come in. They can be used like disposables, except that users send them away for for recharging or recycling when they're dead.  Read More

For many people, commuting by bicycle is a fun, economical and healthy way of getting around. When their bike breaks down, they throw it in their car, drive it to the shop, then drive for several days until it’s fixed. Some bicycle commuters, however, don’t own cars. These people can’t drive their bike to the shop, and have no independent means of transportation as long as their two-wheeler is gone. It is for people like these – and others – that Wyse Cycles exists. As far as its owner Ben Wyse knows, it’s America’s only self-propelled mobile bicycle repair service.  Read More

As a green energy source, geothermal heat is tough to beat, but until recently, it was believed to be economically feasible only in areas with shallow tectonic (volcanic) activity. Now, with a generous grant from Google.org, the search engine giant's philanthropic arm, two scientists from Southern Methodist University (SMU) have pooled together the results from more than 35,000 data sites to paint a very different, almost rosy, energy picture for the United States and, indeed, the world.  Read More

If you’ve ever bought a pet hermit crab, then you may remember also having to buy several sea shells with it. This is because the crabs don’t have shells of their own, and instead have to find empty shells from other creatures and use those. As a hermit crab grows, it’ll need to upsize to larger shells, hence the need to supply it with multiple choices. Unfortunately, every empty shell gathered for the pet trade is one less for the wild hermit crabs to move into. In places where the beaches have been picked clean, the crabs have reportedly resorted to using things such as bottles and shotgun shells. That’s where Miles Lightwood’s Project Shellter comes in – he’s hoping to design 3D printed shells for use in the pet industry, and is seeking ideas from interested artists and designers.  Read More

Italian architecture firm Boeri Studio hopes to merge vegetation and urban architecture, with its Bosco Verticale (Vertical Forest) project. The Italian firm has designed a model that could see the "reforestation and naturalization" of metropolitan cities, by growing forests sky-ways. "Bosco Verticale [is a] device for the environmental survival of contemporary European cities," says Stefano Boeri, who worked with Gianandrea Barreca and Giovanni La Varra on the project.  Read More

Most dog-walkers accept the necessity of cleaning up after their charges, but no one is claiming that it's a pleasurable experience. While we've seen eco-friendly dog waste disposal bags and systems that turn poop into plant fertilizer, we've yet to come across an approach that takes care of both collection and disposal quite like AshPoopie. Still a concept at this stage, the AshPoopie from Israel-based Paulee CleanTech is a kind of portable refuse incinerator crossed with ordinary one-handed pet waste scoop that's designed to turn feces into 100% sterile ash on the spot.  Read More

Eco-tourism is a fast developing industry, as travelers become more conscious about what type of holiday they choose. "Glamping" (glamor + camping) has thus become a popular option for many the eco-tourist, incorporating eco-friendly domes or igloos, that take the camping experience to the next level of comfort. Here's a look at two eco-dome sites in Europe.  Read More
