Self-charging ‘thousand-year’ battery completes lab tests

Green energy startup NDB, which is developing a high-power self-charging diamond-based alpha, beta, and neutron voltaic battery that it claims provides up to thousands of years of charge, has announced the completion of two successful Proofs of Concept tests of its nano diamond battery (NDB). by Rich Pell @ smart2zero.com

In the tests, which were conducted at Lawrence Livermore National Laboratory and the Cavendish Laboratory at Cambridge University, the battery, says the company, achieved a breakthrough 40% charge – a significant improvement over commercial diamonds, which have only 15% charge collection efficiency. The company also announced its first two beta customers, including a leader in nuclear fuel cycle products and services and a leading global aerospace, defense, and security manufacturing company.

The company’s proprietary, universal, self-charging battery creates energy from recycled radioactive waste and is claimed to be able to provide a charge for the entire lifetime of a device or machine, with up to 28,000 years of battery life depending on the radioisotope being used. Its technology, says the company, is poised to completely transform the concept of energy, and can power devices and machines of any size, from aircraft and rockets to electric vehicles, hearing aids, smartphones, sensors and more, all with no carbon emissions.

“Our team is bringing together leaders in the nanotechnology, nuclear science, and diamond fields with military, academic and research backgrounds, and combining our unique mix of expertise has made it possible for us to crack the code in developing this groundbreaking, life-changing solution,” says Nima Golsharifi, CEO and co-founder of NDB. “Moreover, as members of society, we are extremely concerned about the welfare of the planet and are focused on lowering climate change to protect our planet for future generations. With the NDB battery, we have achieved a massive, groundbreaking, proprietary technological breakthrough of a battery that is emission-free, lasts thousands of years, and only requires access to natural air in order to power devices.”

The Proof of Concepts test results, says the company, were a result of its proprietary nanodiamond surface treatment that actively extracts the electric charge from the diamond, allowing the battery to make use of significantly more power than any other battery before it. The battery’s power source is

Taken from intermediate-level and high-level radioisotopes, which are shielded by multiple layers of synthetic diamond, one of the hardest materials to damage or break.

The energy is absorbed in the diamond through inelastic scattering, which is used to generate electricity. Since the universal battery is self-charging, any excess charge will be stored in secondary charge storage such as capacitors, supercapacitors, and secondary cells. The generated, optimized, and stored charge can be used to power devices of any size that require an energy source to run.

Radiation levels from a cell, says the company, will be less than the radiation levels produced by the human body itself, making it totally safe for use in a variety of applications. According to the company, the technology will be cost-competitive with current lithium-ion batteries.

Development of the first NDB commercial prototype battery is currently underway, and though delayed by the pandemic, is expected to be available later this year.

Article PC Watchdog – Automatic reset for remote PCs gone haywire

Today’s PCs are quite reliable, but occasionally they hang and stop functioning. Only a ‘hard reset’ will then be able to bring them back to (useful) life. This project takes care of that automatically. Especially handy with remotely located hardware!While many PCs, including servers, operate unattended and/or at a remote location, it would be very useful to have a function available for sensing a malfunction of the processor and recover the system from such a situation.

High Density 4Mbit Serial EEPROM for Portable Consumer and Medical Devices

Microchip Technology has introduced the 25CSM04, a new high-density EEPROM (Electrically Programmable Read-Only Memory) with 4Mbit Memory, this doubles the 2 Mbit density with which the designers were previously limited to. The Developers were previously using NOR Flash ICs for the 2Mbit + nonvolatile data set application.

Since the EEPROM has a better performance advantage than the NOR Flash, Microchip has introduced a larger 4Mbit EEPROM. The new EEPROM is designed with a standby current (2 µA vs. 15 µA) and has the ability to perform single-byte, multi-byte, and full-page writes; shorter sector erase/rewrite times (5ms vs.300ms); and more erase/rewrite cycles (1M vs 100K).

The Company also has an extensive memory product family that includes serial EEPROMs, NOR Flash, SRAM, and EERAM in all standard serial buses and all standard densities from 128-bit to 64 Mbit. The 25CSM04 IC has been designed to be used in portable consumer and medical devices such as hearing aids, fitness trackers, and glucose monitors as well as in industrial, automotive, and other systems.

“Pushing the top end of what is possible with serial EEPROM supports product innovation,” said Randy Drwinga, vice president of Microchip’s memory products division. “Designers can now reevaluate their systems and leverage this new technology to optimize design performance.”

The 25CSM04 family of memory devices is available in three package options starting at $2.32 in 10,000-unit quantities. For additional information, please visit Microchip’s website.

CZ-3A0x Series Coreless Current Sensors

AKM’s coreless current sensors are high-accuracy and achieve both creepage and clearance distance

Corresponding to the UL safety standard UL61800-5-1 for industrial equipment, AKM has developed the CZ-3A0x series coreless current sensor which achieves both creepage distance and clearance distance greater than 8 mm. It supports a working voltage of 600 VRMS (with reinforced insulation), making insulation design easy. With a wide current detection lineup from ±12.9 APP to ±129.1 APP, 50 ARMS, and two overcurrent protection circuits, the CZ-3A0x series can be used for many applications including AC motors and general-purpose inverters.

The CZ-3A0x series has a low resistance of 0.27 mΩ as the primary conductor resistance with AKM’s original package. As a result, compared to shunt resistors and similar products of other companies, heat generation when applying the current can be greatly suppressed, and 50 ARMS continuous current can be applied. Furthermore, availability with wide current detection ranges from ±12.9 APP (CZ-3A01) to ±129.1 APP (CZ-3A07) are achieved. This enables the adoption of common design of system boards, making it easy to roll it out to other models with different ratings.

In addition, it is suitable for a sensor signal input to a 3.3 V A/D converter in a 3.3 V input system. It has a built-in stray magnetic field reduction function, a challenge for conventional coreless current sensors, contributing to the improvement of system efficiency and precise control in a wide range of applications.

  • Creepage/clearance distance: > 8 mm
  • Supports ±12.9 APP to ±129.1 APP and 50 ARMS low heat generation
  • High-accuracy: 0.4% F.S. (TA = +35°C ~ +85°C typical)
  • Dual overcurrent detection function

Applications

  • AC motors
  • DC motors
  • UPS
  • General inverters
  • Power conditioners

12V to 24V @ 1A Step-up switching regulator using LM2585

This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments. This IC was chosen for its simplicity of use, requiring minimal external components and for its ability to control the output voltage by defining the feedback resistors (R1,R2). NPN switching/power transistor is integrated inside the regulator and is able to withstand 3A maximum current and 65V maximum voltage. Switching frequency is defined by internal oscillator and it’s fixed at 100KHz.

The power switch is a 3-A NPN device that can standoff 65 V. Protecting the power switch are current and thermal limiting circuits and an under-voltage lockout circuit. This IC contains a 100-kHz fixed-frequency internal oscillator that permits the use of small magnetics. Other features include soft start mode to reduce in-rush current during start-up, current mode control for improved rejection of input voltage, and output load transients and cycle-by-cycle current limiting. An output voltage tolerance of ±4%, within specified input voltages and output load conditions, is specified for the power supply system.
