Low Carbon Fashion - Eco-friendly Pencil Printer

This is an eco-friendly printer that makes full use of the pencil tip while allowing the paper to be used again and again. Its ink comes from the lead core powder on the pencil tip. By inserting the extra pencil tip into the small hole above the printer, the pencil tip will be automatically sharpened into powder, and then the principle of electric firing is applied to separate the wood chips from the lead core powder and deposit the lead core powder into its ink cartridge. Its wiping function can remove the A4 paper covered with pencil writing.


Pinless Stapler The principle of pinless stapler is that it folds paper, perforates it, and then folds it with a special mechanical structure and fixes the paper by folding and perforating it. It does not require any staples and does not pollute the environment. The paper is easily stapled together by simply pressing down from the staple item.


Microalgae oil

Microalgae oil production is a new technology for biodiesel production. It uses microscopic organisms that are widely distributed in various waters to absorb carbon dioxide to produce bioenergy. The main principle is: through photosynthesis, carbon dioxide is converted into microalgae's own biomass to fix carbon, and then through induction reaction, microalgae's own carbon is converted into oil, and then the oil inside the microalgae cells is converted into oil outside the cells by physical or chemical methods, and then refined and processed to produce biodiesel.


Soil power generation

Researchers at the University of Pennsylvania in the United States have invented a technology that uses bacteria in the soil to generate electricity. The technology uses proper heating of the soil, leaving only hydrogen-producing bacteria, and uses fermentation to revive the bacteria. These bacteria eat organic matter from garbage and wastewater and excrete large amounts of hydrogen gas. The hydrogen storage equipment in the enclosed "home power station" can store the hydrogen energy to power cars or become the energy source for various fuel cells.
