Some chemicals have demonstrated the feasibility of taking advantage of sunlight to transform a greenhouse gas into a useful product. They have already developed a prototype device that captures solar energy, converts it into electrical energy and “split” carbon dioxide(CO₂), carbon monoxide (CO) and oxygen.

The work has been performed by Clifford Kubiak and Aaron Sathrum from University of California at San Diego.

As your device is not optimized yet, still need to provide additional energy for the process to work. However, expect their results to draw attention to the promising method. (more…)

WASHER (1901)

The first electric washing machine appeared in 1901, thanks to Alva Fisher, using a motor spun a drum including water and soap. The use of the machine became popular when electricity became a commonly used service. Some current models leave the laundry and dry programmers have time and speed sensors that monitor temperature and consumption.

CLEANER (1901)

In 1901 there was a vacuum that needed two people to operate: a bellows to move the vacuum to absorb the dust and another moved the apparatus on the floor.      William Hoover in 1908 designed the first electric vacuum cleaners, initially, were used only in industry.  Years later, would go on to the houses.

A new technique for creating films of barium titanate nano particles in a polymer matrix could allow fabrication of improved capacitors able to store as much as twice the energy of conventional devices. The improved capacitors could be used in everyday appliances like mobile phones, and in applications that require both storage of large amounts of energy and the rapid current discharge.

Because of its high dielectric properties, barium titanate has been of interest for a long time for use in capacitors, but until recently scientists had been unable to produce good dispersion of the material within a polymer matrix. (more…)
