Lotus Eco Elise

15 07 2008

On July 22nd at the British Motor Show, Lotus will unveil their new environmentally friendly sporty roadster, the Eco Elise, which features a number of “greener” improvements. Instead of just decreasing CO2 emissions, Lotus tried a holistic approach to ecology by using sustainable materials (like hemp and eco wool), a cleaner manufacturing process, renewable energy generation and reducing the car’s weight. Overall, the weight saving program for the Eco Elise has resulted in a total saving of around 70.5 lbs over the feather light Elise S, which consequently reduces the fuel required to drive the car.

Are those weed plants in the background?

Although we enthusiastically  welcome the idea of using Hemp in cars ( or any other product for that matter ) may we point out that the concept of using  Hemp in a car is not that new.. (remember Henry Ford?)





How To: Easy Hydroponic Growing

15 07 2008

Hydroponic cultivation need not be complex or expensive, and requires only a little more equipment than indoor growing using soil.

Hydroponic growing differs very little from soil growing. The plants grow and flower in the same light cycle and are fed the same nutrients – nitrogen, phosphorus and potassium (N-P-K,

plus micro-nutrients and trace elements). The main difference is that hydro plants root and grow in a neutral medium which, unlike soil, has no nutrients of its own.

Hydroponic nutrient is water soluble and is immediately available to the plants when applied to the growing medium, while organic nutrients must be broken down by bacteria in order to enrich the soil to which they are added.

Aside from the indoor basics of light(s), timer, fans and air exchange (all of which are required for indoor soil growing, of course), hydroponic growers will require two meters for testing the nutrient water they give to their plants.

  • An electrical conductivity or EC meter measures the amount of nutrient in the feed water and presents it as a simple number, allowing growers to be sure that they do not over-feed or under-feed their plants. Nutrient meters in different regions and countries may measure in other scales: TDS (total dissolved solids) or PPM (parts per million).
  • A pH meter tests the acidity/alkalinity of water. Cannabis prefers an acidic growing medium, so hydroponic feed water is usually lowered to around pH 5.8.
  • Most growers will also require a substance for lowering and/or raising pH. Tap water typically has a higher pH than ideal for hydroponic cannabis, so it usually must be lowered. Household products such as lemon juice or vinegar are sufficiently acidic to lower pH.

In addition, hydro cultivation will require a hydroponic growing medium, such as rock-wool (ideal for starting seeds and clones) or expanded clay-balls (a re-useable medium and an excellent second stage for plants that start in rock-wool), and hydroponic nutrient for the growing and the flowering stages.

In this diagram, plants are growing in rockwool slabs. The reservoir is filled with nutrient water, and contains a pump(attached to a timer) which delivers feed-water to the slabs several times per day.The slabs are inclined so that excess water runs off and flows back to the reservoir.





MIT study suggests caution on new anti-obesity drug in kids

15 07 2008

Anti-obesity drugs that work by blocking brain molecules similar to those in marijuana could also interfere with neural development in young children, according to a new study from MIT’s Picower Institute for Learning and Memory.

Marijuana is known to be an appetite stimulant, and a new class of anti-obesity drugs—such as rimonabant (trade name Acomplia) developed by Sanofi-Aventis and awaiting approval for use in the United States—work by blocking brain receptors that bind to marijuana and other cannabinoids.

Marijuana, derived from the plant Cannabis sativa, contains special active compounds that are referred to collectively as cannabinoids. But other cannabinoids (endocannabinoids) are generated naturally inside the body.

How our brains fend off madness

15 07 2008

A cannabis like substance produced by the brain may dampen delusional or psychotic experiences, rather than trigger them.

Heavy cannabis use has been linked to psychosis in the past, leading researchers to look for a connection between the brain’s natural cannabinoid system and schizophrenia. Sure enough, when Markus Leweke of the University of Cologne, Germany, and Andrea Giuffrida and Danielle Piomelli of the University of California, Irvine, looked at levels of the natural cannabis-like substance anandamide, they were higher in people with schizophrenia than in healthy controls.

The team measured levels of anandamide in the cerebrospinal fluid (CSF) of 47 people suffering their first bout of schizophrenia, but who had not yet taken any drugs for it, and 26 people who had symptoms of psychosis and have a high risk of schizophrenia. Compared with 84 healthy volunteers, levels were six times as high in people with symptoms of psychosis and eight times as high in those with schizophrenia. “This is a massive increase in anandamide levels,” Leweke told the National Cannabis and Mental Illness Conference in Melbourne, Australia, last week. And that is just in the CSF. Levels could be a hundred times higher in the synapses, where nerve signalling is taking place, he says.
