The Green Optimistic

A team of students led by Harus Laksana Guntur, an engineering lecturer at the Sepuluh Nopember Institute of Technology (ITS) in East Java capital Surabaya have developed a mobile kinetic energy charger that can charge your cellphone every time you move. Unlike a battery or solar charger, this new cellphone charger uses the user’s energy to reload mobile phones.

A Chinese developer called Daizi Zheng has discovered a new source of power for cell phones: Coca-Cola. He recently modified a Nokia cell phone to be powered by this juice or any other sugary solution.

Scientists at the University of California San Diego have discovered new plant enzymes that can allow plants to save water while consuming more CO2 from the atmosphere. The enzyme causes the plants to react to CO2 and change how they use their pores and by modifying the enzyme, scientists believe that could be developed more CO2- and drought-tolerant crops.

Scientists at the Tel Aviv University (TAU) are sure that their newest research in the nanotechnology field could lead to the development of a new type of solar panels and glass that need no cleaning and apparently put window washers out of work.

Researcher Takashi Yabe at the Tokyo Institute of Technology claims that he developed a system that can run on solar energy, to refine magnesium and use it as a source of fuel.

A team of scientists at MIT and Michigan along with researchers at the University of California have discovered that artificial photosynthesis could produce electric energy.

Scientists at the University of Georgia have discovered a new way to grow molecular wire brushes that conduct electrical charges. According to the researchers, this discovery is the first step in developing fuel cells for devices such as cochlear implants, prosthetic limbs and pacemakers.

Chunlei Guo, a researcher from the University of Rochester, along with a team of scientists, have created a slab of metal that can push water uphill, defying gravity, by using the capillary effect. It’s the same effect that happens when you put a piece of fabric in a wine glass, for example, and hold it with your hand.

Discover how these guys succeeded extracting TiO2 from a donut and make a solar cell out of it! No kidding!

There is enough material underground to heat 100 million homes for a decade. With this amazing source of energy (the gas hydrates) researchers could develop systems that can provide green and cheap energy for all.

How would you like an engine producing your dear electricity? How would you like that engine to have pistons as high as heat-powered balloons? Well, an environmental consultant from Solartran in Brisbane, Australia, by his name Ian Edmonds, has designed such an energy producing “engine” from the classic and romantic air balloon.

Electric motors have simple designs, are easy to operate and have a great resistance to various environments. That’s why they are to be chosen as alternative to internal combustion engines. This is a trivial experiment showing how you can feel you made a real electric motor yourself. Just for fun.

What you are going to see in this video is nothing you don’t know. In fact, I urge any weird-science reader to try and make the device from the video below, respecting the pictured details. I’ll make it myself from a hard drive plate and a used scotch tape support. Let’s see how much time it works, and if it can be improved.

If this truly works (and I don’t see why it shouldn’t), it is the greatest home-produced energy discovery since the wheel has been founded. Lloyd Tanner uses an incredibly simple assembly of two 4×4 inch wood pieces, and an iron wheel spinning in between.

In the field of hydrogen fuel cell production, Oregon State University researchers have discovered that sewage can produce cheap hydrogen. In comparison with traditional electrolysis technology, sewage can produce hydrogen at a lower cost.

Here’s a method of producing a battery out of some Cola, salt, aluminum and copper coins. It lights a LED and it can be an interesting source of free energy!

Here’s a little tricky experiment that you can do on your own at home. It’s very simple to do, all you have to have is a solar battery (you can buy that cheaply from a scrap store), a bottle, a toy with wheels you don’t need anymore, and a little bit of super glue. It [...]

LTD stirling engines are an interesting idea. They harvest the temperature difference of the environment versus a cold object, and using this they power some pumps.

There are many ways for building of a hull, such as using frame of square lumbers or using F.R.P. Here, we build the hull using piled up boards of balsa. This can be built easily, and can stop the water leakage easily.

Introduction
The success or failure of any biogas plant mainly depends upon the quality of how it is constructed. To construct a good biogas plant, you should not only respect the dimensions as indicated on the drawing but also follow the correct construction method. Hereunder, in a step-by-step fashion, the right construction method of the 2047 [...]
