We have covered robots that climb before, two of them on one day , actually. This ROCR from the University of Utah can actually climb walls like a spider. It’s more like a monkey, honestly.

Keeping cool all of the time during the summer is close to impossible.  There are just some places that aren’t as well air conditioned as others.  If you are particularly sweaty in those situations and want to try to stay cool, this little pocket fan should be of great use to you.  It could easily fit into your pocket and the blades tuck away nicely so that you won’t have to worry about them breaking off while you’re carrying it around.

It’s nice to know that we haven’t abandoned clocks in this digital age, and just when I thought the Morse Code clock was as minimalist as they come, here comes “The Front & Back” clock. See the hands on the clock face? In case you haven’t figured it out yet, they are the batteries.

There are just some gadgets that get neglected in the battery department.  Usually I’ll do as much as I possibly can to squeeze that last drop of power out of the batteries before I’ll go in search of more.  When you’re typically using a remote, you’re all settled into the couch to relax, which makes the idea of getting up to search for batteries rather unappealing.  Instead you could pick up one of these solar powered remote controls and never have that concern again. This universal remote works like every other remote out there, it just happens to use up power in a much more efficient manner.  Even if you happen to use rechargeable batteries, you still have to remember to toss them on the charger when they’re not in use.  With this you’d just have to make sure it was able to soak up a little light, even if it’s artificial light.  You can purchase the Powerplus Leopard Solar Powered Universal TV Remote Control for £9.99 or about $15 through the Big Green Smile .

Nyko is practically getting legendary with its gaming accessories, and they have turned their attention on a problem that I am familiar with: the batteries in the Wii Balance Board.

Lately I’ve been thinking of replacing my wall clock and going for something completely different and with this Canvas Clock that’s exactly what I’ve found.  Printed onto a pretty white canvas is nothing more than a clock.  However, instead of purely being an image like it initially appears, it actually tells you the current time.  It’s a great way for you to have that tabletop clock look except on your wall. The hands of the clock are the only real parts, the rest are just something printed onto the canvas.  To control it and change out the batteries you just remove the canvas from the wall and work it all from the back.  It only requires a single AA battery, which is of course not included.  The whole thing measures 29.7 cm long.  You can purchase it through Latest Buy for $36.56

I swear I’ve been on the thermometer patrol.  I’ve been casually searching for one for a while now, but just haven’t found that one that pulls me in.  My needs are basic, covering the usual basics like affordability and a battery-free design.  Well this one does just that, it’s not like the big weather stations that can predict the weather all day long.  It just keeps you posted on the current state of events and the lows and highs.  It does all of that without needing you to switch out the batteries. It’s completely solar powered and just suctions to your window.  It could be used on any glass surface, but that would make things complicated if it weren’t a window.  The suction cups are set up to stick on the outside, then while you’re warm indoors you can check the outside temperature.  You can also see what the low was for the night before.  It’s also thankfully pretty affordable.  You can purchase one for $25.10 through Amazon .

I’ve bought the occasional heat packet that you can jam inside of your socks to keep my feet warm, but those are a very disposable method.  I prefer to have something that I can rely on more often, which is where battery-powered socks come in.  They’ll make it possible to stay warm and all you have to do is remember to switch out the batteries.  Plus, these are oh so stylish. This isn’t the first pair of heated socks featured here on Coolest Gadgets.   Anyone that wears this version is going to have to be highly committed to staying warm.  Instead of just having a small unit directly on the sock to adjust the heat like the other pair, this one sends a wire up the inside of your pants leg that attaches to a plastic box.  That plastic box stores the batteries and allows for you to turn on the socks as well as up the temperature.  Not only are you going to have to deal with some extra wires, these socks have an added painful aspect to your wallet.  It’ll end up costing you $265 from the Japan Trend Shop and that’s not including the $21 charge for shipping.

For those who had Lite Brite when they were kids know that the pegs were not actually tiny bulbs in and of themselves. I remember the commercial seemed to call it “magic”, but all it was a light bulb behind a plastic pegboard with black construction paper sandwiched in between. This is different from Sketch Art

Buying rechargable batteries is always far better than purchasing the disposable ones.  However, it’s still not a perfect method.  It helps so that you’re throwing away less batteries, but at the same time you’re still plugging something into the wall and using your electricity to charge the batteries.  Instead of plugging a battery charger into the wall, this ReNEW would allow for your rechargable batteries to become even more eco-friendly.
