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

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

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

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.

Question: Will Chevy Volt Run Windows?

Question: Will Chevy Volt Run Windows?

I guess that the Chevy Volt has been one of the most hunted electric cars from the beginning of this year. GM has done all their possible to keep the secret from the press(?), but it seems that several images and specs have “leaked”, acting as a teaser for the information thirsty public.

Prius vs BMW M3 vs MPG at Top Gear: Who Wins?

Prius vs BMW M3 vs MPG at Top Gear: Who Wins?

I really didn’t like what Top Gear guys did the last time to a Prius, but this time I think they have a point (partially). They’re going to race a Toyota Prius (1.5L)versus a BMW M3 (4L). Of course the BMW will win the competition… but wait… not the speed competition. The BMW will get 19mpg and the Prius only 17mpg. Why is that? Does it prove that the Prius is more gas-guzzler than the BMW? No.

ABC News Reports the Progress of Developing the Chevy Volt

There are a lot of speculations around the future Chevy Volt, the series car that it’s said to revolutionize the car industry. Although there hasn’t been much proof that they have the battery to power the electric-hybrid car, they’re confident in their success, or at least that was wanted to be seen on this abc news video clip. Watch it. I think they’re going to make it, because probably they’re going to be using the EEStor technology or something equivalent, technology that has only recently been unveiled.

Michael Strizki`s Solar/Hydrogen/Geothermal Powered House - Amazing!

Michael Strizki’s house is the most low impact house I’ve ever seen. He lives his life off-grid, because his home system feature solar panels, 10 hydrogen tanks filled with the excess energy from the solar panels, with the hydrogen taken out of water, and a 15 year-old geothermal system, that covered its price 8 times since it was installed.

Video: Jack Nicholson Drives Hydrogen Car in 1978!

This video is a clip from a 1978 CBC News, showing Jack Nicholson driving a hydrogen powered car. The concept existed since then, the hydrogen was packed in high pressure tanks, and the engine’s timing (top dead center) was retarded a bit (probably 8 degrees, it’s a common value). And, as extra value, the hydrogen was obtained from solar power, through some solar panels, cutting edge tech at that time.
