Engineering Students Create Cheap Way to Tell When Water is Safe to Drink

Engineering Students Create Cheap Way to Tell When Water is Safe to Drink

There's one way that will usually make a concept go from a plan to the real deal pretty quickly: make it cheap. While some concept designs may focus on helping the environment, or finding new ways to help humans in certain situations, they may make it too impractical due to costs. But, if you can manage to create something that is practical and costs less than five dollars to make, we're pretty sure that means you've got a winner on your hands. At least, that's what students from the University of Washington are hoping.

ET3 Tube System Wants to Take You From New York to Beijing in 2 Hours

If you're claustrophobic, then travelling on any kind of vehicle for transportation is probably pretty rough. Especially an airplane, where you're sitting right next to a lot of people, in a relatively small space (depending on how you fly, of course). So maybe a giant tube system wouldn't be to your liking. But, if you've got to get somewhere, even somewhere around the world, in a hurry, the ET3 system could be just what the world has been waiting for.

Solar Vox is a Portable Solar-Powered Charger Looking for Funding

For a concept design to become real, and find its way into consumers all over the world, it needs money. That's where Kickstarter comes in. A service designed to help creators find the means to get their ideas off the ground, and hopefully onto shelves where people can actually buy them. We've seen an iPod Nano watch hit the big time thanks to Kickstarter, and now a solar-powered portable gadget charger is looking for some funding. Designed by Eric Strebel, it's a simple device with a lot of potential.

Finding alternative energy sources is a cause that many corporations and companies are attached to. And governments, along with entire cities, aren't new to clinging onto new methods for saving energy, and costs.

The permit was just approved recently, the company behind the plant, SolarReserve, announced late Wednesday.

BamBoo Electric Vehicle is a Grown-Up Golf Cart

When it comes to concept cars, Frank M. Rinderknecht is a name that has become synonymous with outrageous and unique designs. With his Rinspeed company behind him, Rinderknecht is able to bring to life some of the craziest ideas when it comes to automobiles, but it looks like next year will be a bit different. He's taking a more "laid-back" approach with his latest idea, which he is calling the BamBoo, and opting for something a bit more simpler, but still unique in its own right.

Solar power is a hot topic for those who want to be eco-friendly. Or, for those who just want to find ways to save on energy bills.

It's been recently discovered that the Oriental Hornet, which features an iconic yellow strip around the hornet's abdomen, is actually solar powered.

Poland’s Inspiro is a Recyclable Subway Car [Video]

With partners like Siemens and BMW, there's no surprise that Poland would want to go ahead and move forward with the aspirations of one day in the near future of having a completely recyclable subway car. The country has put forward plans to make the dream come true, and have teamed up with the pair of companies to make it happen. The end result, if everything goes to plan, should be a subway car that's near 100% made from recyclable items, and is ready to carry passengers by 2012.

Nissan Reveals Fuel Efficient ECO Pedal System

Nissan Reveals Fuel Efficient ECO Pedal System

For a car only available in Japan (for now), a car called the Nissan Fuga, Nissan has created a system called ECO Pedal, a system that'll improve fuel efficiency anywhere from five to ten percent. How does this pedal work, you might ask? It provides resistance so that the user will be less inclined to press it all the way down. But there's more, right? It can't just be harder to press down the gas pedal, right? There's just a little bit more, it's not just a brick under your pedal, but essentially it's just a system that suggests you be more sensible about how hard your pressing the gas. I know more than a couple people who could use this.
