Pump ambient air (which contains CO2) into a plastic tank, filled with sea water, through a gas distributor. Carbon dioxide (CO2) from the air will dissolve in the sea water. The surface of the sea water should be exposed to direct sunlight. Phytoplankton will be multiplied on the surface of the sea water by the natural process of photosynthesis, which utilizes CO2 and sunlight (as in the hot Benguela sea stream on the South African East Coast, which captures CO2 and produces phytoplankton for marine fish consumption). The plankton biomass produced by this process can then be harvested for renewable clean energy purposes and agricultural fertilizer, e.g. 1) Production of methane heating gas in a bio-digester tank to serve ...

EXECUTIVE SUMMARY

1.1INTRODUCTION
In the world, usage of electricity is increased day by day for each and every purpose of people. If the necessity of electricity increased but the production level is low. The main purpose of this invention is cost effective, without fuel, no pollution, noiseless, and constant power supply without fluctuation.

In this product specializes in helping home owners and business owners become more energy efficient with the ultimate goals of helping them to save money on their utility bills, decrease consumption, and increasing the comfort of their home and industries.

PROJECT OBJECTIVE
The objective of this demonstration project is to develop and demonstrate a power delivery system using existing equipment where possible. The ...

There has been a rapid increase in the demand for battery packs in recent years due to the growing popularity of residential power banks, electric vehicles, laptop computers, etc., all of which require battery packs. Since battery packs wear out over time, this increase in demand has begun to cause an increase in the need to dispose of old battery packs. Some battery packs can be recycled by mechanically breaking the pack down into its constituent metals and reselling the raw materials, but this is not always feasible. Often old lithium-ion battery packs are incinerated or are disposed to landfills. When lithium-ion battery packs wear out, it is generally only a small subset of the cells within the battery ...
As hazardous molecules such as HC, CO and Nox from automobile exhaust and air pollution can cause allergy and coughing and trigger cancer, Green Island Smart Ecological Purification System has thus been designed. By heating up ceramic substrates, the Green Island system transforms hazardous molecules into nutrients and oxygen required for algae cultivation, and electricity generated by algal photosynthesis is used for reproduction and cultivation lights to keep the temperature of ceramic substrates in the Green Island system to boost circulation. Additionally, aquatic plants growing on Green Island can exchange nutrients with algae to form ecological symbiosis. Excessive algae which can be picked and made into biomass petroleum become energy suppliers. Green Island not only purifies air, but also ...
Mr. Richard Phillips Feynman, a famous genius scientist, introduced a Brownian ratchet in his book “The Feynman Lectures on Physics” (see Figure 1). The Brownian ratchet is also referred to as Feynman’s ratchet, Feynman’s thermal ratchet and the like.

The Brownian ratchet is a submicron-scale micromachine in which components move randomly by Brownian motion. The micromachine can be manufactured by using microfabrication technologies such as semiconductor fabrication technologies, nanotechnologies and molecular machine technologies.

The Brownian ratchet is a micromachine extracting useful work from Brownian motion. Details of the Brownian ratchet are omitted here. Please search the internet etc. for details of the Brownian ratchet.

As an important point, Mr. Feynman denies that the impeller and the ratchet rotate continuously ...

What happens when an astronaut gets sick? Current missions require that astronauts take medications with them from Earth. But many medications degrade over time, especially protein drugs, and the necessary stockpile takes up precious mass and volume on a spacecraft. With the push towards long-term human missions to the Moon and Mars, this model is not sustainable. Even on Earth, there are many people without access to critical medicines because regional production and distribution systems are lacking, especially in remote areas, resource-poor areas and in austere environments. Our solution is an “Astropharmacy” – an innovation that allows protein drugs to be produced “on demand,” even in the remote environment of space, using genes as templates for cellular or cell-free ...

Purpose:
To provide a sustainable source of desalinated water from ocean surface water by having floating platforms filter, distil and collect the water, using solar energy.

Benefits:
Current desalination techniques require large amounts of energy to run the plants. Furthermore the waste salt creates an environmental problem via sterilisation of the land it is dumped on. My concept hopes to retain the salt within the ocean, without concentrating it in the water, by using a slow but steady method.

The platform can be used along the coastline near settlements, especially for impoverished villages, and to assist areas hit by natural disasters which have had their infrastructure destroyed.

Market Potential:
A large scale production and installation of the platforms could ...

A method for designing a plastic that is comprised of RF sensitive monomers whereby they can react with specifically tuned RF fields to de-polymerize thus converting the polymer into its monomer components.

Plastics are known for their extremely useful properties and have invoked a materials revolution since it's creation. Durable, watertight, light weight & easily manufactured, plastics have become ubiquitous in our modern world. However, on the down side, plastics are too perfect and long lasting, the disposable of which has become an issue of world wide, environmental, concern.

Current methods of handling plastic waste include recycling, re-purposing, land filling, incineration, sublimation, bio-degradation/digestion, temporal degradation, photo degradation & conversion via chemical (including enzymatic) reaction. Each method has it's advantages and disadvantages, ...

Experts have estimated that 8.3 billion metric tons of plastics have been made and approximately 5 billion metric tons have already been discarded, with an abysmal recycling rate of only 600 million metric tons. This is despite the fact that recycling alone can save 40 to 90 percent of the inherent energy in plastics relative to the production of virgin plastics—energy savings, which if harnessed, could result in massive-scale economic and environmental advantages. Up to 40 percent of all plastics are used for minutes to hours to days in single-use packaging applications (items commonly composed of plastics like polyethylene, polypropylene, polystyrene, or polyethylene terephthalate, also known as PET), while the estimated time for many plastics to degrade in a ...
Eight million metric tons of plastic waste, including polyethylene terephthalate (PET) bottles, enter the oceans each year, creating huge man-made islands of garbage. Experts estimate that by 2050, there will be as much waste plastic in the ocean by mass as there are fish. It’s a global environmental problem that poses a serious risk to wildlife, particularly in marine environments.

Now imagine something as simple as a microbe that can degrade those plastic bottles. Such an organism exists. Ideonella sakaiensis 201-F6 is a recently discovered bacterium that can degrade PET using its PETase enzyme, but PETase doesn’t yet work fast enough to solve plastic recycling at the industrial scale.

However, while working to solve the crystal structure of PETase, an international ...
