Be it known that I, NIKOLA TESLA, a citizen of the United States… have invented certain new and useful Improvements in Apparatus for the Utilization of Radiant Energy…
It is well known that certain radiations–such as those of ultra-violet light, cathodic, Roentgen rays, or the like–possess the property of charging and discharging conductors of electricity, the discharge being particularly noticeable when the conductor upon which the rays impinge is negatively electrified. These radiations are generally considered to be ether vibrations of extremely small wave lengths, and in explanation of the phenomena noted it has been assumed by some authorities that they ionize or render conducting the atmosphere through which they are propagated. My own experiments and observations, however, lead me to conclusions more in accord with the theory heretofore advanced by me that sources of such radiant energy throw off with great velocity minute particles of matter which are strongly electrified, and therefore capable of charging an electrical conductor, or, even if not so, may at any rate discharge an electrified conductor either by carrying off bodily its charge or otherwise.
My present application is based upon a discovery which I have made that when rays, or, radiations of the above kind are permitted to fall upon an insulated conducting-body connected to one of the terminals of a condenser while the other terminal of the same is made by independent means to receive or to carry away electricity a current flows into the condenser so long as the insulated body is exposed to the rays, and under the conditions hereinafter specified an indefinite accumulation of electrical energy in the condenser takes place. This energy after a suitable time interval, during which the rays are allowed to act, may manifest itself in a powerful discharge, which may be utilized for the operation or control of mechanical or electrical devices or rendered useful in many other ways.

…It will be found that when the radiations of the sun or of any other source capable of producing the effects before described fall upon the plate P an accumulation of electrical energy in the condenser C will result. This phenomenon, I believe, is best explained as follows: The sun, as well as other sources of radiant energy, throws off minute particles of matter positively electrified, which, impinging upon the plate P, communicate continuously an electrical charge to the same. The opposite terminal of the condenser being connected to the ground, which may be considered as a vast reservoir of negative electricity, a feeble current flows continuously into the condenser, and inasmuch as these supposed particles are of an inconceivably small radius or curvature, and consequently charged to a relatively very high potential, this charging of the condenser may continue, as I have actually observed, almost indefinitely, even to the point of rupturing the dielectric. If the device d be of such character that it will operate to close the circuit in which it is included when the potential in the condenser has reached a certain magnitude, the accumulated charge will pass through the circuit, which also includes the receiver R, and operate the latter…
Transparent solar technology represents 'wave of the future'
See-through solar materials that can be
applied to windows represent a massive source of untapped energy and
could harvest as much power as bigger, bulkier rooftop solar units,
scientists report in Nature Energy.
Led by engineering researchers at Michigan State University, the
authors argue that widespread use of such highly transparent solar
applications, together with the rooftop units, could nearly meet U.S.
electricity demand and drastically reduce the use of fossil fuels.
“Highly transparent solar cells represent the wave of the future for
new solar applications,” said Richard Lunt, the Johansen Crosby Endowed
Associate Professor of Chemical Engineering and Materials Science at
MSU. “We analyzed their potential and show that by harvesting only
invisible light, these devices can provide a similar
electricity-generation potential as rooftop solar while providing
additional functionality to enhance the efficiency of buildings,
automobiles and mobile electronics.”
Music for Relief a non-profit organisation founded by Linkin Park to assist those affected by disasters and poverty raised more than $8 million between 2005 and 2015 to help the survivors of more than 30 disasters. The organisation has also planted 1.3 million trees to offset climate change and brought solar power to people living in Haiti, Africa and South America.
In 2015, Chester Bennington and Joe Hahn donated their birthdays to Music for Relief. They asked friends, family, and fans to give to MFR for their respective birthdays with the agreement that whoever raised the most money at the end of the challenge got to smash a cake in the loser’s face.
it’s interesting to see microgrids/self-produced energy becoming a reality - it’s being marketed as storm resilience but also could facilitate minimising dependence on capitalist structures, resilience against local authorities as well.
