SPS-ALPHA: U.S. R&D Solar Power Satellites

The satellite shape resembles a wine glass.

According to a report by the British media on the 12th, NASA has been contemplating the use of space satellites to collect solar energy, and then transmits the light beam back to the earth receiving station to convert it into electricity for use by users. At present, NASA has put this idea into practice and assigned an initial fund to California's Altemis Innovation Management Consulting Company, entrusting it with a study of this concept to prove its feasibility.

John Mankins, president of Altemis Innovation Management Consulting and former senior engineer at NASA, said that this technology will eventually become a reality. He said that compared to other solar energy collection methods, this design is more cost-effective.

It is reported that this solar-powered satellite named SPS-ALPHA (above) resembles a huge wine glass and consists of thousands of thin curved mirrors that can be turned and solar panels that convert solar energy into microwaves. Afterwards, these microwaves will be transmitted back to Earth from the bottom of the "cocktail glass".

In a related report on NASA's official website, Mankins called the project "an innovative, bionic way of solar power in space." He pointed out that once this project is successful, the idea of ​​building a giant platform with tens of thousands of small units and transmitting thousands of megawatts of power to the earth through wireless transmission may come true.

However, at present, scientists do not know how much energy can be transferred back to the earth about 150 million kilometers away from distant space. After this method of converting solar energy into microwaves and transmitting it back to Earth, this problem is solved. Maybe you have the answer.

Sources said that while the United States is conducting this study, a group of Japanese companies and the Japanese Aerospace Development Agency are also planning to launch solar space stations within 20 years.

Microflow Peristaltic Pump

The Microflow Peristaltic Pump can adjustable the flow rate or speed while the pump is working. And can dispense in a forward or reverse direction, This type of peristaltic pumps also with calibration functions that ensure the high accuracy filling for the user.

You can set the filling time/pause time and copy number on the program. When the set time arrives, the pump will stop automatically and repeat filling depend on the copy number you setting on the program,

The Microflow Peristaltic Pump is suitable for micro-dose filling, And the pump can work with various tube sizes to meet different volume dosing.

If you want the low pulse liquid dosing, the pump head we have 3 roller 4 rollers 6 rollers 10 rollers for your option.
