Solar-Powered Robot Lawn Mower

I so need one of these!  Oh, wait, no grass to mow.  But you probably have some, and just look at this beauty!  At $4,000, it’s no yard-sale find, but with built-in sensors that detect yard obstacles, it reduces the amount of work you have to do down to simply setting the thing out and turning it on.  Swimming devotees will recognize this approach as like that of the pool Simon, and it also falls close to the Roomba technology.   And of course, like many products featured here, it’s totally powered by the sun.  With one of these and a few free hours to watch it wander, you might actually be HAPPY when your spouse tells you to mow the lawn!

Plasma LED lights for 12V systems

So here’s a great idea for all you solar panel owners out there:
These plasma lights use next-to-no energy, and are wired for 12V (aka your solar panel/battery). As you can see, they emit a lot of light for the power used, so you could light up a room with a bulb or two. Nice!

Click on the banner ad below to buy one today! (yeah, I don’t usually advertise like this, but your purchases will help me support this blog.)

5mm & 8mm wired LEDs

  • ALL LEDs Each come with wire & resistor attached for 12V use
  • Wire is at least 1 Feet in length
  • Will also work for 6V-13V DC applications
  • Assembled in the USA! Best Quality!
  • Water Proof! We don’t tell you! We show you!

Here’s an amazing, “why didn’t someone think of it before” idea. Of course, it’s from the ever smart and innovative students of MIT. (Side plug, if you’re ever looking for some great reading, check out MIT’s Technology Review, available online or in stores. It’s loaded with cutting-edge and interesting ideas for the future)Basically, this idea takes the power of human gravity and converts it to usable energy.

Yep. It’s that simple. What I want to see is a super-charged home version of the system, so you can actually power your home as you run around after your dog (or kids), for instance. Visit their site for more info.

Crowd farming

How can we find alternative energy from simple human movement? Well, the idea for this alternative energy source came from a pair of MIT students Tad Juscyzk and James Graham. The duo announced their ideas at the Holcim Forum 2007 awards ceremony where they won top honors.

The project seeks to convert the energy of human movement in places where it is abundant and dense, like in urban settings, to energy suitable for consumer use. Juscyzk and Graham’s crowd farm was based in Boston’s South Station terminal. The floor of this popular railway destination would contain a responsive sub-flooring system made up of blocks. These nodes would depress slightly when stepped upon and would be in station’s main lobby. The friction of the blocks as people walked would generate power through a dynamo, or a device converting energy of motion to this new form of alternative energy.
