AI Data centre expansion and industrial electrification are pushing up the power grid load and giving renewed attention to the efficiency of conductor materials. TechCrunch reported that Arturus, a United States start-up company, was trying to reduce energy losses during transmission and distribution by adapting copper and aluminium conductors, and had completed $8 million in seed ship financing.

Financed by Initialized Capital

This round of financing was led by Initialized Capital, Toyota Ventures, Breakthrough Energy Discovery, 1517 and Wirefame Ventures. The company indicated that the new funds would be used to expand sample capacity and advance the testing of materials in different scenarios.

Arturus was created by the founder and CEO Amir Mashal. The company had previously been operating in hiding. Mashal stated that AI development and Electrification of industries were pushing the electricity grid to higher loads, and that the traditional practice was to increase the amount of copper, but that the company wished to improve the transmission capacity of existing conductors with material modifications.

Use lasers to inject nanomaterials into metal conductors.

The Arturus programme uses lasers to inject carbon nanomaterials into copper and aluminium in order to reduce the energy loss of the conductor from heat. According to the company, if conventional copper materials were replaced by such materials, the electricity line could carry more currents at the same size.

Mashal states that copper will decrease its conductivity after heating, and the higher the temperature, the greater the loss of heat. The company hopes to alleviate this problem through improvements at the material level.

Based on the measurements given, such materials, if used in the grid, could theoretically reduce transmission losses by about half, releasing an average of about 3 per cent additional power capacity, up to 10 per cent when the grid is most congested.

  • An average of about 3% of electricity is released.
  • Up to 10% when it's high.
  • The current sample size is a few centimetres long guide

Start with drones and data centres.

While the grid is considered to be the end-use direction, Arturus now prioritizes targeting smaller and more verifiable scenarios, including drones, robots and data centres.

According to the company, a few percentage points of increased efficiency may have a significant impact on these scenarios. For data centres, reduced conductor heat also means that cooling needs are expected to decline; for drones and electric vehicles, lighter systems or higher energy efficiency may be possible.

Mashal is currently promoting prototype development in a garage in Malibu, California, where several centimetre-long guidance samples can be produced at this stage. The company plans to upgrade capacity to tens of metres with new financing for more complete application testing.

The goal is not to change the system.

Arturus states that this new material will be designed in a “direct replacement” approach, as far as possible compatible with the current use of copper and aluminium, without requiring a re-engineering of existing systems or additional training installation and processing processes.

Next, the company plans to use the materials for the testing of components such as electrical circuits and parent platoons of electrical distribution equipment. If the test results are stable, such materials may enter larger power infrastructure scenarios in the future.
