How to Make Your Own Solar Cell From a Bunch of Scrap Diodes (Video)

Posted by Mihai Sandru in How to..., Video on May 10, 2012

Buying photovoltaic panels from the store and installing them can prove a costly process, so why not try making a pair of your own at home? Warning: they may not generate much electricity, while losing some of it, but if it works, wouldn’t it be a shame not to have tried? Especially since you don’t [...]

Shocking Video: How Human Pollution Affects Wildlife on Remote Pacific Atoll

Posted by Ovidiu Sandru in Pollution, Video on April 18, 2012

I love animals. I love birds. I always imagined that birds are safe in their natural habitats, in forests or islands or places of the sort. But they’re not. In fact, animals are not safe even at 2,000 miles away from the nearest continent. The ghost of our unfulfilled dreams, ignorance and thirst for money [...]

SpaceX Dragon: The First Spacecraft Using Solar Panels (Video)

Posted by Mihai Sandru in Solar Power, Video on January 9, 2012

I wonder what it feels like to know that you’ve contributed to space expeditions and, indirectly, to the future of mankind? Very proud, I assume, as must feel the engineers from SpaceX, a private space transport company led by Elon Musk, also Tesla Motors’ CEO. During its first mission to the International Space Station, the [...]

New Nissan Leaf Ad Attacks Everything Gas-Powered, Including The Chevy Volt

Posted by Ovidiu Sandru in Electric Vehicles, Video on May 27, 2011

I don’t currently own a Nissan Leaf, but what I know is this car benefits from excellent advertising. After the polar bear ad, Nissan effectively attacks everything that runs on gas in an over-dramatized scenario. It also uses the Chevy Volt image at the end to suggest this one also runs on gas, like all the other things in “this” world.

Eric's Homemade Mirror Solar Concentrator Melts Metals and Concrete in Seconds (Video)

Here’s Eric Jacqmain, who built his “Death Ray” out of a normal satellite dish with 5,800 small mirrors on it. He worked about 24 hours on the project whose results you can see in the video below.

Polar Bear Hugs Nissan LEAF Owner In The Company's Most Touching Ad

Posted by Ovidiu Sandru in Electric Vehicles, Video on September 13, 2010

Nice idea for a car that pretends itself to be more than hybrids are, and though less than fuel cell powered ones. Batteries are still a pollution factor, but hydrogen extracted by solar power means are not.

Blest Can Turn World's Scrap Plastic Into Usable Oil Having Lower CO2 Output

Posted by Ovidiu Sandru in New Inventions, Video on August 23, 2010

Plastics are made from gas, extracted from oil fields. Through a specific process, the gas is transformed into what we know as bottles, coffee cups and toys. The bad part is that each of them ends up in a landfill, eventually.

Jake Explains How to Build a Super-Cheap Solar Water Heater

Posted by Ovidiu Sandru in How to..., Solar Power, Video on June 29, 2010

Solar water heaters are not a new idea, but people who often complain about rising energy prices should be reminded to use such devices to help heat their homes and take a shower, too.

An Idea to Naturally Harvest Algae for Biofuels By Using Stable Ocean Currents

Posted by Ovidiu Sandru in Biodiesel, Video on June 8, 2010

Here’s an interesting idea to cultivate algae that could be transformed into biodiesel. The basic idea is that people should use the stable currents that exist in the Pacific ocean to carry algae from one point to another, time during which the algae should mature with the ocean’s support and some slowly-dissolving nutrients that should float along with them.

How to Measure a Stirling Engine's Efficiency (video)

Posted by Ovidiu Sandru in How to..., Stirling engine, Video on May 21, 2010

The next video shows a Stirling engine while working to achieve its best, powered by a 70W light bulb. The poster also shows how he measured various parameters of the engine, like speed, torque, input/output power.

The Bottled Water Industry: Selling Tap Water 2000 Times More Expensive

Posted by Ovidiu Sandru in Video on May 17, 2010

I admit I use to buy bottled water when I get thirsty and there’s no nearby water source available, but a kiosk selling stuff. Where do all water bottles get to, what is this huge industry doing with all the garbage it leaves behind?

Working Magnetic Motor Demonstrated at Delft University in The Netherlands

Posted by Ovidiu Sandru in Free Energy, Magnetic Power, Video on April 26, 2010

An inventor from Turkey, Muammer Yildiz, as Overunity.com and Pesn.com report, has just demonstrated his own version of a magnetic motor at the University of Delft, in the Netherlands, in front of an audience made of university staff and students. His device ran for more than 10 minutes, rotating a fan. The wind speed was measured and it has been concluded that the power of Yildiz’s magnetic motor is about 250 W.

DIY 3D Solar Panel Powers Electric Motor From 2 LED Flashlights

Posted by Ovidiu Sandru in How to..., Solar Power, Video on January 21, 2010

Ryszard says it’s much more efficient to assemble solar cell this way than put them directly into light, where you’ll lose a lot through reflection back into the environment. Some recently invented anti-reflective coatings may even accelerate the light’s absorption into the solar cells. This is one of the advantages.

Video: Alsetalokin's Magnetic Motor Working

Posted by Ovidiu Sandru in Free Energy, Magnetic Power, Video on January 13, 2010

Many have tried to build magnetic motors, but it’s difficult, and the difficulty comes from the fact that you somehow have to isolate and beam the magnetic field into only one direction. Here is another experimenter that uses rotating magnets on the stator, that if aligned properly to a certain pattern that he tries to find every time the motor starts.

Hydrogen On-Demand System Boosts Van Mileage by 94%
