Grow Mushrooms At Home : Start From Spawn | Permanomades. Cultivate food without land… impossible you say ? Look at this post and think “Mushrooms !”. When we found ourselves with no garden, no soil neither sun, the idea came of growing mushrooms indoors in our living room and kitchen, and recycle many waste, such as coffee ground or cardboard. Results are really impressive! What is the importance and benefits of mushrooms ? Mushrooms are magic living organisms and need very few things to grow. They are also delicious, have many medicinal benefits, and growing them is the best way to get them fresh. They are also very precious for all ecosystems, as recyclers for wood and organic material.

Les Nanos Technologies dans les Aliments Les nanos technologies (ou nanos matériaux) sont aujourd'hui présents dans un grand nombre de nos aliments issus de l'agroalimentaire et des produits industriels.

Elles ont pour effet d'améliorer la consistance, la saveur, le goût, la conservation, pouvoir appetant, ect.. Les effets potentiels sur l'organisme ne sont à ce jour pas mis en évidence aussi bien sur l'apport bénéfique pour la santé que sur la dangerosité et l'exposition à certaines maladies. Il n'éxiste pas de législation imposant aux fabricants d'étiqueter dans la composition des produits manufacturés la présence de nanos technologies dans leurs produits. Les législateurs à la cour européenne essaient de ménager la chêvre et le chou. Un texte devrait aboutir sur l'étiquetage imposé par la commission européenne, mais quand?

The Kit That Turns Any Car Into A Hybrid | This Could Be Big - Yahoo! News - Framasoft Framafox. Even with an increasing number of car manufacturers building hybrid cars, it's hard for a lot of people to justify buying a new car for an extra 10 miles per gallon in fuel savings.

But a former IBM engineer and current professor at Middle Tennessee State University named Charles Perry and his students have designed a hybrid retrofit kit that may soon turn any gas powered car or truck into a hybrid. It's been in the works for the past few years, but the technology is getting closer to becoming a reality. We spoke with Professor Perry this week to find out more. Prof. Perry's design takes a lot of the confusion out of hybrid technology, making it more realistic and accessible to car owners. The kit attaches to the rear wheels of just about any car or truck, and is powered by a lithium ion battery in the trunk. Sure, not everyone could install it themselves, but Perry insists that if you can change your brakes, you can install the kit. TransportationAutoshybrid cars.

Taraxacum kok-saghyz, often abbreviated as TKS and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion,[1] is a species of dandelion native to Kazakhstan that is notable for its production of high quality rubber.[2] T. kok-saghyz was discovered in Kazakhstan in 1932 by the Soviet Union in an effort to find a domestic source of rubber.[3] Etymology[edit] Kok-saghyz is derived from the Kazakh kok-saghyz, with kok meaning plant and saghyz meaning rubber or gum. [citation needed] Description[edit] T. kok-saghyz fruits Taraxacum kok-saghyz is a perennial plant with a yellow composite flower characteristic of the Taraxacum genus.

It is a diploid species that reproduces sexually, and produces good pollen.[1] Another species, a triploid apomict that also has horned bracts and produces rubber, T. brevicorniculatum Korol. has frequently been misidentified as T. kok-saghyz.[1] Growing conditions[edit] Utility[edit] Rubber[edit] Dandelion by-products[edit] References[edit] Garbage Enzyme - Multipurpose Uses & Safer and Cleaner Alternative. I have been using Garbage Enzyme for several months now.My papaya tree is flourishing so are other plants (note: do not overuse).Mix Garbage Enzyme with my shampoo so that the toxic chemicals are neutralized by the Garbage Enzyme.Take out foul odors from toilet - only bleach comes close and as fast as Garbage Enzyme.Mix also with floor cleaners as we have a 'stockpile' of floor cleaners so have to use it all; floors are squeaky clean.

Garbage Enzyme can be used as an alternative to bleach and other cleaning compounds.It can effectively used as:- as a household cleaning liquid - to remove foul odors, molds and grime in the kitchen and toilet - as an anti-bacterial and anti-viral agent - to drive away insects - to clean carpets and remove ticks - for laundry washing and ironing - for mopping floors - for cleaning cars What is Garbage Enzyme?
