The poo problem has vexed pet owners since the first wolf started hanging around early human encampments. Wouldn't it be sweet if that pile of pup waste just disappeared? A new invention promises to turn Fluffy's excrement into ashes.

The AshPoopie is the brainchild of scientist Oded Shoseyov from the Hebrew University of Jerusalem. He is aiming to reduce the huge number of plastic bags full of poop that end up in the trash all over the world.

A built-in pooper scooper on the bottom picks up the offending material. It combines it with the contents of a replaceable cartridge and what looks like a set of rotating paddles. At this point, some patented incinerating magic happens and out comes sterile, odorless ash. It's a poop blaster!

Google has created a $75 million fund with Clean Power Finance, a company that offers financing for residential solar panel installations.

The investment will enable 10,000 homeowners to install solar panels on their homes.

The upfront cost is the largest obstacle to installing residential solar panels, and solar installation companies don't always have the means to offer financing. Clean Power Finance seeks to overcome that hurdle by offering installers a way to provide financing to potential customers, while also giving companies without ties to the solar community a way to invest in the industry.

Google, the investor in … Read more

We know school's already in session for most kids, but it's still September, so it's not too late to do a back-to-school-related post. At least we hope we're not too tardy.

Anyway, we spotted these school-themed tablet/smartphone "smart" Toddy cloths on the company's Web site and were mildly amused. They're made out of premium microfiber that's treated with a microbe shield, have a plush side to clean and silk side to polish, and are machine washable in cold water. A single Toddy will run you $9.99, but if you … Read more

Entrepreneur Brad Hines' first solar company crashed and burned, but he's already started another venture, a story which offers cues on how the entire green-tech sector can reinvent itself in tough times.

In 2005, Hines left his work as a NASA engineer to build a radically new and powerful type of rooftop solar collector. But even after taking in tens of millions of dollars from top-shelf investors, the company, Soliant Energy, ultimately failed and its intellectual property was sold off, reportedly at bargain basement prices.

Now Hines is at work on another solar startup called Thermata with a whole … Read more

My iPad screen has never again looked as good as the day I peeled the plastic wrapper off. My phone looks like I've taken it hiking and set it in the dirt. Which I have.

I'm not the only person with dusty and dingy electronics. That's why there's a thriving industry of electronics cleaning products. Most of these involve some sort of liquid that you spray on. The Qmadix Smudge-Free Dry-Foam Cleaning Kit dispenses with all that dampness.

The $19.99 kit comes with antimicrobial microfiber cloths, but the star of the show is the dry foam spray that comes in a little bottle. Qmadix touts the foam's smudge-resistant, dust-resistant, and anti-static properties.… Read more
