Us Patent For Solar Collector Patent Patent

Which patents are related to batteries?

There are patents related to various battery technologies such as Li-ion, Lead-acid, Ni-MH, Redox-flow, Na-ion, Mg-ion, Li-Air, and others. Patents also cover battery components like materials, electrodes, electrolytes, separators, battery cells, battery packs and systems, thermal management systems in batteries, and Battery Management Systems.

Who owns the battery patents?

The lab and the U.S. government still hold the patents, because U.S. taxpayers paid for the research. In 2012, Yang applied to the Department of Energy for a license to manufacture and sell the batteries. The agency issued the license, and Yang launched UniEnergy Technologies. He hired engineers and researchers. But he soon ran into trouble.

Which company has the most patents for a solid-state battery?

Toyota announced its solid-state battery development efforts and holds the most patents. In 2015, Sakti3 was acquired by Dyson. In 2017, John Goodenough, the co-inventor of Li-ion batteries, unveiled a solid-state battery, using a glass electrolyte and an alkali-metal anode consisting of lithium, sodium or potassium.

How to design a solar collector network?

A methodology for the design of solar collectors networks is introduced. Network structure represented by a series–parallel collector arrangement. Design approach based on a thermo-hydraulic model. Network of collectors determined based on the thermal and hydraulic needs.

What is a thermo-hydraulic model for solar collector networks?

A thermo-hydraulic model for solar collector networks is presented and its solution is graphically displayed with the length of the exchanger plotted against the number of arrays in parallel. The thermal and the hydraulic models are solved separately so that two solution spaces are represented in the same plot.

How does a solar collector work?

In the case of solar collectors, the working fluid used to transfer heat to the process either in an open circuit or in a closed circuit is water. A solar collector can be viewed as a particular type of heat exchanger and the set of solar collectors needed for a particular application, as a network of heat exchangers.

What is a cylindrical solar collector?

Innovative cylindrically designed solar collector is highly compatible with nano fluid as working fluid. Cylindrical continuous tube construction offers lesser frictional resistance and more exposure to solar radiation compare to multiple tubes attached with headers in conventional collector.

Is thermal design solar collector a good choice for industrial applications?

To date, the thermal design solar collector is well developed and of the domain of many researchers and manufactures; however, there still remains the hydraulic aspect to be brought into consideration particularly in industrial applications where the mass flow rate of the working fluid is large and pumping power becomes an important operating cost.

What are the problems with solar collectors?

The former problem refers to the design of the set of solar collectors and the latter to the design of the heat recovery system, including the storage system that will take into consideration operating variables such as time, which makes most low temperature processes, discontinuous in nature.

What is the difference between solar collectors and solar panels?

Many people mix up the definition of solar collectors and panels, but the difference is significant. While collectors generate heating energy, solar panels produce electricity. Renewable energy sources are the future of our planet. By now, wind power plants generate the most energy, but the solar power industry is improving the most dynamically.

Should you use solar panels or a solar collector?

If you would only use solar energy to heat up your properties, then go with solar collectors. But if you would cut your electricity bills and use solar power on a wider scale, try solar panels. Factories sometimes use solar collectors and panels as an additional energy source for fossil fuels.

What is a solar collector?

Solar collectors may be referred to as solar parabolic apparatus for more complex installations and solar air heat for less complex installations. The more complex collectors are employed in solar power plants for heating water to produce steam which in turn drives a turbine connected to an electric generator for generating electricity.

Are solar collectors better than solar cells?

But we need both electricity and heat. For the heat demand, actually the major demand of energy, a solar collector will be more efficient and appropriate than a solar cell, but for electricity you have to use a PV panel. Both solar collectors and solar cells can be installed as integrated modules in roofs and facades, substituting other cladding.

Are solar thermal collectors more efficient than solar panels?

Solar thermal collectors are highly efficient compared to solar panels. Hence the difference in the number installed on your roof. Solar thermal collectors are 80% efficient while solar panels are only 25% efficient. Thermal collectors convert most of the solar irradiation that they absorb into heat. Hence, their higher efficiency rates.

How does a solar energy collector work?

On the other hand, a solar energy collector gathers heat by absorbing it directly from the sunlight. The collector carries out the conversion of sunlight into usable energy forms. The efficiency of solar panels can range between 11-19 (even 22) percent depending upon the module.
