Harvesting clean hydrogen fuel through artificial photosynthesis

A new, stable artificial photosynthesis device doubles the efficiency of harnessing sunlight to break apart both fresh and salt water, generating hydrogen that can then be used in fuel cells.

The device could also be reconfigured to turn carbon dioxide back into fuel.

Hydrogen is the cleanest-burning fuel, with water as its only emission. But hydrogen production is not always environmentally friendly. Conventional methods require natural gas or electrical power. The method advanced by the new device, called direct solar water splitting, only uses water and light from the sun.

“If we can directly store solar energy as a chemical fuel, like what nature does with photosynthesis, we could solve a fundamental challenge of renewable energy,” said Zetian Mi, a professor of electrical and computer engineering at the University of Michigan who led the research while at McGill University in Montreal.

Faqrul Alam Chowdhury, a doctoral student in electrical and computer engineering at McGill, said the problem with solar cells is that they cannot store electricity without batteries, which have a high overall cost and limited life.

I am also an introvert, procrastinator, and get anxiety from doing certain adult stuff even though it could be done rather easily.

Having an assistant that could help me with that would, I think, be extremely helpful.

No He Didn’t… These People Did Instead…

Wilhelm Conrad Röntgen, Physics, 1901: Wilhelm Roentgan was awarded the first Nobel Prize in physics for his discovery of X-Rays on November 8, 1895. Not many know this but Tesla was working with X-Rays prior to Roentgen in 1892, but used the term “radiant matter” instead. He conducted numerous experiments and some of the first imaging, which he called “shadowgraphs,” using these unknown rays in his laboratory before its destruction by fire on March 13, 1895. Tesla was also the first to warn the scientific world on the harms of these rays if not used properly.

Marie Curie, Pierre Curie and Antoine Henri Becquerel, Physics/Chemistry, 1903/1911: The three shared the 1903 Nobel Prize in Physics for their discovery and work on radioactivity in 1898. Madame Curie won the 1911 Nobel Prize in Chemistry for her discovery of radium and polonium, also in 1898. Tesla discovered radioactivity in experiments with X-Rays in 1896, and published many articles on the subject in scientific periodicals prior to the three.

Joseph John Thomson, Physics, 1906: Thomson was awarded the Nobel Prize for his discovery of the electron in 1897. Tesla originally called electrons “matter not further decomposable” in his experiments with radiant energy in 1896, but his discovery of the electron goes back as far as 1891 in a debate he and Thomson had about Tesla’s experiments with alternating currents of high frequency. Tesla claimed that his experiments proved the existence of charged particles, or “small charged balls.” Thomson denied Tesla’s claim of verifying these particles until witnessing Tesla’s experiments and demonstrations given in a lecture before the Institute of Electrical Engineers at London in 1892. Thomson then adapted to Tesla’s methods of high frequency and was able to use equipment which allowed him to produce the required frequencies to investigate and establish his electron discovery. 

Guglielmo Marconi and Karl Ferdinand Braun, Physics, 1909: Both shared the Nobel Prize for their work and development of radio. Marconi is known for proving radio transmission by sending a radio signal in Italy in 1895, but it is a fact that he used Tesla’s work to establish his discovery. Tesla invented the “Tesla Coil” in 1891, which Marconi’s inventions relied on, and the inventor proved radio transmission in lectures given throughout 1893, sending electromagnetic waves to light wireless lamps. Tesla filed his own basic radio patent applications in 1897, which were granted in 1900. Marconi’s first patent application in the U.S. was filed on November 10, 1900, but was turned down. Marconi’s revised applications over the next three years were repeatedly rejected because of the priority of Tesla and other inventors, but was finally able to bypass Tesla’s work and secure his own. After Tesla’s death in 1943, the U.S. Supreme Court made Marconi’s patents invalid again and recognized Tesla as the true inventor of radio.

Charles Glover Barkla, Physics, 1917: Barkla was awarded the prize for his work with Rontgen radiation and the characteristics of these X-rays and their secondary elements and effects. He was educated by J. J. Thomson. Again, Tesla worked with and explained these radiations in full detail throughout the late 1890s, showing that the source of X-rays was the site of first impact of electrons within the bulbs. He even investigated reflected X-rays and their characteristics such as Barkla.

Albert Einstein, Physics, 1921: Einstein was awarded the prize for his theoretical theories which are still praised today, and also his discovery of the law of the photoelectric effect. In 1905, Einstein considered that light has a nature of both a wave and a particle. This lead to the development of “photons,” or photo electrons, which gave light a wave-particle duality. Now it must be noted that Nikola Tesla wasn’t just a theoretical physicist like Einstein, but was an experimental physicist as well. In 1896, Nikola Tesla was the first to propose that energy had both particle-like and wavelike properties in experiments with radiant energy. He set up targets to shoot his cathode rays at which upon reflection, projected particles, or vibrations of extremely high frequencies. Nikola Tesla preceded Einstein by 4 years on the photoelectric effect publishing a patent titled “Apparatus of the Utilization of Radiant Energy.” filed in 1901, based off his experiments with radiant energy. He had a far better understanding on the matter than Einstein, mostly because he actually experimented with the issue to prove his theories.

James Chadwick, Physics, 1935: Awarded the prize for his discovery of the neutron in 1932. Tesla’s discovery of neutrons goes back to his work with cosmic rays, again in 1896, which are mentioned in the next bit. He investigated and discovered that cosmic rays shower down on us 24/7, and that they are small particles which carry so small a charge that we are justified in calling them neutrons. He measured some neutrons from distance stars, like Antares, which traveled at velocities exceeding that of light. Tesla succeeded in developing a motive device that operated off these cosmic rays.
