I just bought this solar charged (7 hrs charge = 5,5 hrs use) flashlight from IKEA. The first impression is an rather inelegant flashlight, but it is intended to stand on its metal support. The main body feels very rugged and is quite heavy. No squeaking parts. The metal support however snaps off its pivot hinges without any help. The on/off button have a surprisingly good feel to it. It is now standing in my window, side by side with the Sun Jar (Picture coming up). See all pictures tagged Jäppling
Rechargeable Batteries with Solar Cells Project by Knut Karlsen
At home i always have some batteries lying around, either rechargeable or normal ones. Usually they are empty, but i'd like them to be always fully charged. I could use a normal charger and there is a lot of solar devices that charge rechargeable batteries. I wanted it simpler; why hasn't anyone made a battery with integrated solar cells? The idea of the "SunCat" batteries where born. The batteries should just bask in the sun like a cat and left for a while, in a sunny window, they would slowly recharge.
Prototypes During my research for my diploma i was in touch with scientists at IFE that experimented with the production of flexible solar cells. They where kind enough to send me some samples in the right dimensions that i could use for the prototypes (full set at flickr):
I had some older NiMH rechargeable batteries that i glued the flexible Photo Voltaic (PV) cells onto. The PV cells are rated at 1.8V and…
This is how I got the Connection Proxy from the Sony Ericsson Java ME SDK to work on Windows 7 64-bit version: Install your phones PC Suite to get all phone networking driversGet & Install 32-bit JDK Get & Install semc_java_me_cldc_sdk.2-5-0-5.exe (Place it in default location C:\)Get the eclipse SDK for win 64 as we need one file from this zip.Get RXTX library as we need additional files from this zip.Find "org.eclipse.swt.win32.win32.x86_64_3.5.1.v3555a.jar" in eclipse SDK & place it in the folder "C:\SonyEricsson\JavaME_SDK_CLDC\OnDeviceDebug\lib\devexp\plugins"Edit "connectionproxy.cmd" so that "org.eclipse.swt.win32.win32.x86_3.4.0.v3448f.jar" becomes "org.eclipse.swt.win32.win32.x86_64_3.5.1.v3555a.jar".Find "RXTXcomm.jar" in the rxtx package & place it in the "C:\SonyEricsson\JavaME_SDK_CLDC\OnDeviceDebug\bin" folderPlace "rxtxSerial.dll" in the "C:\SonyEricsson\JavaME_SDK_CLDC\…
An easy to read article that gives a good overview over current situation, in the US atleast, and pointer to the road ahead. ... regulators in dozens of states began to implement decoupling, a policy that rewards utilities for coming in below generation targets. Suddenly, companies could profit by promoting efficiency. This quote from the article suggests the benefits of changing the behaviour of power generators from max production to max efficiency. Schemes like that would have a great impact if realised all over the world.
