Google has rolled out a search engine with a specific target in mind: your house, more specifically how much area of your roof could be covered in solar panels, what that would save you and where you can look for companies to install a system for you.

Interested homeowners can input their addresses and get realistic illustrations of how many solar panels would fit and what their potential cost savings on energy bills are likely to be.

A complex data comprising everything from your home’s location and orientation to the presence of shade from adjacent trees or buildings – but this set is broken down into simple information for users.

Google, of course, is well-positioned to make this Sunroof tool effective, combining its Google Maps and Earth data that can sort out not just the footprint of a building but its 3D space too, and thus shadows. It also has all of the other information at hand, like average temperatures, sun exposure, cloud cover.

Users of the tool can tinker with variables, but ultimately are given a recommended installation that maximizes the potential output and thus puts more back in homeowner pockets long-term. For now it is limited to the San Francisco Bay Area, Boston and a few other locations, but they have plans to expand around the country.

Whether at a gallery without wall plaques, visiting a business establishment or hanging out at a friend’s home, having Magnus on your smartphone will let you see what the wall art around you is all about.

Pointing your device and clicking a picture brings up all kinds of details about a given work, including the name of the artist, medium of the work and its dimensions … as well as its price (either current, if available, or most recent if sold and off the market).

One of its more fascinating features, however, is  its comparative software that brings up what the app considers to be related works of art, by type, style and price. It does this by tapping into a crowd-sourced database of 8,000,000 works of art (and growing).

One risk here, of course, it that it reinforces the commodification of art. It is also sort of a strange function in that it boils art down to tastes and preferences … just because another piece looks similar or is priced in the same range does not mean a user should go out and buy it.

Magnus was 31-year-old German art entrepreneur Magnus Resch, known for his work on best Larry’s List, an active database of contemporary art collectors. His response to this kind of criticism: “Why is it ethically wrong to show users prices of an artwork they are interested in?

“If you are willing to spend $10,000 on an artwork,” he continues, “you should know that another gallery put the work on auction a year ago for $7,000 and it didn’t sell. Knowing this will allow the collector to make a more conscious decision.” Of course, for most of us, spending $10,000 on a piece of art is a bit unrealistic, so perhaps the general public is not really the target audience for the app.

A multifunctional masterpiece built with crowd-sourced design ideas and a small-space vision by the founder of TreeHugger, this New York City apartment is now for sale for $995,000.

The star of Graham Hill’s LifeEdited, the unit boasts transforming furniture, sliding walls, secret panels and hidden resources from an array of manufacturers and custom installers.

Per the Gizmodo video above, the space unfolds to accommodate everything from dozen-plus dinner parties to overnight guests when you pull out the magically-long dining table or push an entire wall to one side.

From the living room (which splits into bedrooms) to the bathroom and kitchen, lots of little tricks make it all work, including a microwave that doubles as an oven and modular burners that can be deployed on demand.

Everyone knows a million dollars does not go quite so far in Manhattan, but some might still wonder if the place is worth the asking price. Cool factor and high-tech tweaks aside, though, it is worth noting that other units in the building have Zillow estimates of 1.5 million dollars in some cases, so at the very least this high-sounding price may not be wildly off base.
