Recently, I had the pleasure of helping a friend by waiting for PG&E at his house, where there was no gas or electricity. Well, I waited all day from 8AM to 8PM, 12 hours and PG&E still didn’t show up.
But the good thing was, I was able to last the full 12 hours on batteries and all the gadgets I own have paid off.
For laptop, I brought my
It seems that French consumer affairs minister has met with an Apple exec to discuss the latest iphone “explosion” problems in France and other parts of the world.
iPhone exploding, is that possible?
Yes, the battery of the iPhone has been reported to “explode” at random occasions ever since its birth. Apple is claiming that their iPhones do not explode but history says otherwise. Apple Nanos in South Korea have been recalled in the past due to “faulty” batteries, pos
Here’s a super, innovative way to convert a chest freezer into a highly, efficient refrigerator. (See PDF schematics here.)
My chest fridge (Vestfrost freezer turned into a fridge) consumes about 0.1 kWh a day. It works only about 2 minutes per hour. At all other times it is perfectly quiet and consumes no power whatsoever. My wind/solar system batteries and power-sensing inverter simply love it.
Here’s a nifty idea for future reading lamps, a dynamic hand-powered lamp that is completely driven by the energy generated by your hand, kinetic they call it.
Really cool, great idea!
Karin Johansson’s lamp is a wonderful and eco-friendly concept that uses the globe of the earth as your source of light and the kinetic energy of your hands as the source of power. A dynamo placed inside the globe converts the kinetic energy to light, when you spin it. It’

We have seen touchless garbage cans all over the place in the last couple years but this DIY speech-controlled garbage can is a better idea that will move via your voice commands.
The garbage can will come to you following a black line and stopping when i

An autonomous Robotic fish is on its way to fish out pollution. With the increasing number of toxic waste in our waters, it seems that a robotic solution is necessary and the researchers from University of Essex are working around the clock to develop this cool fish that can use its sensors to determine any pollutants that are present.
These robot fish will relay the location of contaminants via Wi-Fi underwater and they can assimilate with other fish. Using GPS, they can also navigate themselv
Here’s a really cool flashlight that uses 2 capacitors to power the whole thing. Best of all, the capacitors only need to be charged 3 minutes to last more than 24 hours.
For dummiesCapacitors are a great way to store electricity, and of course even better when you can come up with great ideas for flashlights like this. (Also see HowStuffWorks explanation of how capacitors work.)
In this project, you will make a fl
I have to say I’ve been fighting a LOT of gophers while I used to live at my parent’s house. I did use the Sonic Mole Deterrent which requires 4 D-sized batteries and would run out every couple weeks or so but here’s the solar alternative that will keep going once you insert it into the gophers’ holes.
These Sonic Deterrents basically make noise, which is really annoying to the rodents. (and to you too.)
Of course, one trick to deterring these nasty little gophers is to not use the Sonic Deterent all the time, m

I’d have to say this is one of the coolest toys I’ve seen in awhile. It’s a lego-like pieces that can be assembled together and it requires NO BATTERY! The Topobo runs on some sorta kinetic motors, meaning it’s great for kids to learn movement without use of any electricity.
That’s right, no batteries are required to make these toys move, as the Topodo comes with a special set of kinetic memory motors. They work by having
Here’s a guy who built a really powerful (lookin’) electric bike, fitted with batteries that can jump even cars. There’s even an onboard GPS so you can never get lost while a full charge gets you up to 150 miles.
Watch the video and become “impressed”:
