Designed by Max Frommeld and Arno Mathies, this nifty foldable boat was made from a single, standard-sized sheet of plastic and can easily be transported just about anywhere. Each boat is equipped with a pair of oars plus waterproof, floating cushions that can users can cling onto if the boat should capsize.

The zip tie DIY bicycle snow chains idea from Fritz Rice, the DIYer on these photos. This MacGyver trick isn’t new, but now that winter is here, it’s worth bringing up once more, and it’s also a low-cost solution to keep on winter biking.

This cool rider would be a perfect gift. It allows you to ride on its board or disconnect the board and be pulled while on your skates, skateboard, etc. The engine speeds up to 12 mph and it provides one hour of runtime per charge.  Via

Driven by pedal power, the Blue Space is a two-seater submarine that created by the Saint-Petersburg State Marine Engineering University(MIT). The Blue Space will not only be cheaper to buy and run than existing submersibles, it will be simpler to operate, requiring no special training or expertise. The submarine is meant for two and would require a propulsion capacity of 0.4–0.8 kW, to generate the required speed of 2-3 knots for between two and four hours as compared to the other human-powered submarines which require about 2.5–5 kW to maintain an underwater speed of 2-3 knots, considering it is difficult to generate a propulsion capacity underwater. MIT has made this possible through both its innovative design as well as what they call the “Coanda effect” which assumes that “if an air or water jet is blown out through a flat slot in tangential direction, this jet adheres to the surface on a comparatively large spacing from the slot. At the same time, rarefaction or thrust on the surface is generated.” The prototype has been around since 2003, but is still looking for investors to turn real. MIT is banking on the UV’s relatively cheap price tag of between USD$30,000-$70,000, as well as its cheaper cost to operate and service, to find a market.  [Via]

Contrail created by Studio Gelardi, is a tool that attaches to your bike’s seat tube and leaves a colorful chalk line behind you as you ride. The goal is to encourage a new cycle of biking participation by allowing the biking community to leave a unique mark on the road and to reclaim this crucial shared space. It lets bikers take same route, and aslo reminds fellow cyclists where it’s safe to ride if more bicyclists using the Contrail. The Contrail was a finalist in Design 21′s Pedal To The Medal competition and is not in yet in production.  [via..]

This mini Deep Flight Submarine that looks like a fighter jet, with its thin body, two sets of wings and two tail fins, was created for venture capitalist Tom Perkins by Hawkes Ocean Technologies. Built to withstand ocean depths of up to 400 feet, the carbon fiber electric submersible can seat two, and stay underwater for up to five hours and travel at speeds up to 6 knots. The Sub is powered by batteries and the turbines that drive the ship were made with special care to be incredibly quiet. The price starts at around $1.3 million(Super Falcon), but you can get another model($350,000) which cannot dive as deep as the Super Falcon.   [via CNN & Dvice]

This image helps to explain the phenomenon of “Why Do Freeways Come to a Stop?”. It happens to most drivers at least a few times a year. You’re sailing along on the freeway when you’re forced to come to a stop, or at least a crawl. You can’t see why things are slowing around the bend – and when you get there, traffic is moving better. Traffic planners call this a “shockwave.”  [via..]

I must admin that I have never seen a bike like this before. It’s a bike attached to a derelict shopping cart. This is a nice way to save a shopping cart and a bike that might otherwise end up in a landfill.  [via..]
