The Green Optimistic

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.

Build a Fuel Cell with a couple of Band Aids, an MEA and a few scraps of stainless steel bug screen by Gavin D. J. Harper.
The story as to how this design came into being is probably a little too much information, but worth sharing none the less. Having spent some time playing with Fuel [...]

German scientists have found a way of transforming body heat into electricity using circuitry.The discovery means that we may be able to operate our mobile phones using nothing but the warmth of our hands in the future.
New circuits make it possible to harness body heat for generating electricity, scientists at the Fraunhofer Institute [...]

The simplest fuel cell ‘burns’ hydrogen in a flameless chemical reaction to produce electricity. In order to ‘burn’ the hydrogen, a fuel cell needs a source of oxygen and this is usually obtained from air. The only by-product from this type of fuel cell is water.
Unlike a battery, a fuel cell does not store chemicals [...]

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 [...]

In the times when gas prices rise and rise, and there’s no optimistic future for our pockets, hydrogen and Brown’s gas generation become more and more viable for our cars. Check out this experiment, if you like the idea.

Maybe the title’s aim is too high (it’s a long way ’till there), but Tesla, followed by other scientists along the last century, discovered the principle of propulsion using strong electromagnetic fields. It’s not about traveling on the ground, but from the ground up, with an extraordinary speed and ease.
