By using radioactive materials you could be seeing 30 year batteries in your laptop without a single charge. Work being funded by the US Air Force Research Laboratory is going ahead which will hopefully see some cool batteries created.
The batteries are named betavoltaic power cells and are constructed from semiconductors which is radioisotopes as an energy source. They will be small and thin and create a reaction that doesn’t emit heat.
My fear of this is all that radiation sat on your lap… surely that cant be good for you. I am all for long life power sources for mobile devices but this one sounds plain scary. Expect to see these batteries in 2 - 3 years time.

Ross Lovegrove, designer of beautiful, yet useful, things, has teamed up with Artemide and Sharp Solar to produce these solar-powered street lamps that are to light up the Ringstrasse outside Vienna’s Museum for Angewandte Kunste (that’s the Museum for Applied Arts and Contemporary Art.) They’ll be going up on a tree-line boulevard, so expect the effect to be awesome.

By modifying a laser pen and using a detector you are able to play music over distances that could reach half a mile. To do this the laser needs to be modified by using amplitude modulation. This is then pointed at the sensor which picks up the changes, converts it in to a signal that can be used as music. As with anything with a laser in, be careful when you try anything and do not look at the laser as it could damage your eyes.
To build the device you need to gather together a few components such as a potentiometer, toggle switch and a phototransistor to name a few and then follow the instructions over at Instructables.
