This is just a reminder that I've started a page here on CleanTechnica for sharing other notable cleantech stories from around. You won't see this in the article stream on the front page or in your RSS/Twitter/Facebook feed if that's how you follow us. You have to go directly to: Cleantech News (http://cleantechnica.com/cleantech-news-daily/), also linked in the left sidebar of all CleanTechnica pages. I update the page almost daily. This is my roundup from the past day or so (it's been an exceptionally busy day after the long weekend)

Specialized challenges are usually pretty entertaining – wacky ideas come to life to compete, and often garner some pretty impressive results. The upcoming World Solar Challenge in Australia should deliver some fun; competitors must drive from Darwin to Adelaide, a total of 1,864 miles across the desert, without using any fossil fuel

It's not uncommon to see incentives for buying an electric car, but owning one is another matter entirely.
Electric cars have many qualities making them attractive as urban commuter vehicles – particularly when driving through heavy traffic. The question of how an EV does on a longer road trip is one that does not as of yet have a definitive answer. France, for example, is installing charging stations on its highways, but that project isn’t finished

Fleet owners and consumers need to know if an electric vehicle will provide sufficient range with their present driving habits. The EV Profiler is a sensor that is plugged into your vehicle and a system that can provide hard data. Fleet owners and consumers may find this kind of hard data reassuring.

Solar roads have been a dream of countless cleantech lovers for awhile now. And there's actually a company with the name Solar Roadways. We've written about the potential of solar roads and solar bike lanes a number of times over the years, but there's news out now that Solar Roadways has received a $750,000 grant from the Federal Highway Administration to build a parking lot in Idaho paved with solar panels, the most practical application of the idea I've heard of in the

Electric cars have giant batteries (useful for a number of things besides driving the actual car, even). Also under consideration as the primary power source for electric cars (and buses, motorcycles, yachts, etc.) is the lithium ion capacitor

A hydrogen fuel cell-powered hybrid electric bus supplied by UTC Power for the Alameda-Contra Costa Transit District has set a performance record by operating for over 10,000 hours. The milestone is another step toward reducing the life cycle cost of hydrogen fuel cell-powered vehicles, which produce zero emissions and are more than 50% efficient in terms of converting energy to power.
