It is said that the air we breathe in the places where we live and work can often be 5 to 10 times more noxious than walking on the street, along with the dangerous chemicals found in commonly used household products. Designed by Mathieu Lehanneur and David Edwards of Harvard University, ANDREA is an air purifier which uses indoor plants to filter air.
Originally known as BelAir, the design has gone through a number of tests in order to make it available to consumers with updated features. The device relies on plant’s natural phytoremediation capabilities to remove volatile organic compounds (VOCs) from the air. Simply place any houseplant inside the container and the integrated, specially designed fan draws in ambient air toxins and circulates them around the plant’s leaves and roots, which absorb and metabolize the toxins. Although any plant can be used, the best performing plants are those which are actually quite common, including Spathiphyllum (Peace Lily), Marginita Dracaena (red edged Dragon Tree), Chlorophytum comosum (Spider Plant) and Aloe Vera.
Drawing on NASA research, the botanical air purifier removes common household VOCs, including formaldehyde and other toxins emitted from paint, carpets, and adhesives, and re-circulates clean air into your home.
One of the hottest debates in physics today is over the true nature of space: Is it a 'luminiferous aether' (see Wikipedia) or is it some abstract, ten-dimensional, Reimannian construction like Dr. Albert Einstein proposed in his Theory of General Relativity? If it does, indeed, require a superdimensioned construction to explain the physical laws of the universe, one must wonder why this construction could not be replaced by one using real and observable dimensions like width, length, and depth... If, on the other hand, space is a 'luminiferous ether' or some tenuous 'fluid', then one wonders why the functions of the physical laws of the universe cannot be observed; and, hence, translated into a mathematical construct of reality... of three real dimensions with time expressed as a ratio of relative distances and vectors.
Strange as it may seem, space has already been properly described right here on Earth as far back as 1954! Space is a 'fine structure'... a 'tenuous medium, fluid or field'. All gravitational, electromagnetic, and electrostatic phenomena occur as results of various interactions of energy 'waves' in this 'fluid space'. In pages 172-174, 176, 178 and 180 of Scientific American in 1954, a brilliant discussion giving three-dimensional explanations of many nuclear phenomena (based largely on previous discussions written by Douglass Crockwell) was conducted by Albert G. Ingalls. Crockwell's explanations offer the only real solution to the apparent paradox which certain nuclear events present to the researcher: A particle sometimes behaves like a wave. The discussion stated:
"It seems reasonable, as a first thought to accept each particle-field relationship as an inseparable something, which is perceived sometimes in one fashion and sometimes in another. We might also think of the particle portion of the effect as that which is experienced radial to the course or potential course. We know that some relationship of this sort exists, whether or not it is exactly as stated. Variation of one effect is accompanied by a reciprocal variation in the other effect. In other words, the more the particle field manifests itself as a particle, the less it manifests itself as a field, and vice versa."
Scientists in the US have developed a new technique that sprays a burn patient's own cells on the burn to help regenerate the skin and drastically reduce recovery time. The gun has been under development since 2008 and has now been used to successfully treat more than a dozen patients.
The Skin-cell Gun works essentially like a sophisticated paint spray gun. It was developed by Professor Joerg C. Gerlach and colleages of the Department of Surgery at the University of Pittsburgh’s McGowan Institute for Regenerative Medicine. The concept was first introduced in 2008.
Until now burns have usually been treated with skin grafts, which involve taking skin sections from uninjured parts of the patient’s body, or growing sheets of skin artificially, and grafting them over the burn. The grafts can take several weeks or even months to heal, and during the recovery period patients are prone to infections because of the damage to the skin, which is the body’s first line of defense against pathogens.
Scientists have been able to regenerate skin in the laboratory for decades, but the process takes two to three weeks and the sheets of skin produced are fragile. When grafted on, blisters can form beneath it due to secretions, and can push up against the sheet and damage it.
A new Californian startup, Solaren, claims to have committed to deliver 200 MW power from the Space, beamed down to the Earth by 2016.
In the interview CEO of Solaren Gary Spirnak revealed :
"This will be the world's first SSP plant. While a system of this scale and exact configuration has not been built, the underlying technology is very mature and is based on communications satellite technology. "
For over 45 years, satellites have collected solar energy in earth orbit via solar cells, and converted it to radio frequency (RF) energy for transmissions to earth receive stations. This is the same energy conversion process Solaren uses for its SSP plant.
Interestingly enough that the Solaren website remains very scarce on the information about the company. Except for the flashing logo and contact email address there is nothing to see. I would think this page belongs to geocities free websites rather than leading to the brightest rocket science entrepreneurs.

Gemasolar has completed the construction of the world’s first solar power plant capable of generating electricity all day and night. As significant as the “all night” feature sounds, keep in mind that the fact that solar power plants do not normally generate electricity at night is not actually their biggest reliability obstacle — the electricity generation interruption from clouds is more problematic (see more on that below). Luckily, this power plant design tackles both issues.
This plant is able to produce electricity all day and night due to the fact that it has 15 hours of energy storage to back it up, when cloudy and at night too.
The fact that weather varies unpredictably during the day, causing power production to fluctuate is much more important than the lack of sunlight during the night, because power plant operators know exactly when night time starts, so any other power plant can be scheduled to start for night time operation.
