Magic Water

The new Billi B-5000 is amazing. It's a tap that gives you instant boiling or chilled water. And other than being super convenient, it's super well designed. It actually looks like a tap (a nice tap) and not some kind of retro space station. It's got the smallest footprint of any boiled/chilled tap available. It also saves you power and money, there is a handy little calculator on the Billi website which shows you exactly how much you're saving.
Because life's too short to wait for the kettle to boil.

Switch

Rafael Morgan Industrial Design has created rotative light switch designs that graphically represent energy waste using common positive/negative symbols.
I think these are super clever in that they encourage you to actually think about the power you're using each time you flip the switch, and are still a great, aesthetically pleasing design.



Rafael Morgan has heaps of other great products and ideas on his website, from lighting to furniture and other fun objects.

There is a Light That Never Goes Out.

Industrial designer, Sergio Silva, describes his Oyule lamp as 'a modern day light bulb that has travelled back in time, providing light as a traditional oil lamp'.

The lamps come in pairs and there are only 66 sets available, retailing for US$650.

A steel component in the bulb's base makes the lamp sit at a precarious angle.

The folks at Intructables thought the price tag was a little too much to handle and so have intructions to make your own slightly less clean and chic version.

Though maybe the $650 price tag buys you a little certainty that it won't explode dramatically in your face.
