The Power of Raw Cannabis
This is a must-watch video featuring some of the top researchers on the healing effects of Cannabis (Marijuana) in it’s raw form, eaten or juiced. Eating raw cannabis as medicine, dietary essential: new research. Cannabis is a dietary essential that helps all cell types function more effectively. Is a medicine: anti-inflammatory, anti-oxidant, probably has some direct activity against cancerous cells. This plant can do phenomenal things, but not if you aren’t taking a high enough dose.
Cannabis is the most important vegetable in the world.
A rocket mass heater is a special type of masonry stove that stores the majority of its heat in a large, thermal mass (like a bench attached to the stove itself). When built properly, a rocket mass heater burns a lot more efficiently than a modern day wood stove and lets out practically no exhaust — only carbon dioxide and steam.
You can use practically any type of wood material as feedstock. Yard debris, sticks and even scrap lumber all can be used to burn inside the rocket mass heater. This makes them efficient and practical to use if you don’t live next to a forest with a large source of firewood logs.
Unlike the modern wood stoves on the market today, rocket mass heaters can be built completely on your own. Plans and blueprints for a wide variety of different rocket mass heaters exist online. And, depending on the size and type you decide to build, many can be completed in only a few days.
One of the keys to a rocket mass heater is the different twists and turns that occur in the inner chamber of the heater itself. To start, the wood stock is put in vertically, so that only the bottom of the wood pieces burn. The bottom of the wood stock chamber then takes a sharp, 90-degree angle in toward the inner workings of the heater so that the fire itself is burning sideways, parallel with the floor. At the end where the fire is burning, the inner chamber takes another sharp 90-degree angle up toward the ceiling. This section is called the heat riser and it’s where all the magic happens. This heat riser section is contained in another structure like a barrel, so that there is a space between the insulated heat riser and the barrel that surrounds it.
As the heater is working, the heat riser gets extremely hot. This heat causes a convective current that continues to pull the fire into the riser. The sharp turn causes the smoke to be constantly mixed with fire and is consequently burned off, leaving you with an extremely clear exhaust comprised mostly of steam and carbon dioxide. As the hot air enters the riser, it travels toward the top of the riser and up into the barrel that surrounds the riser. At the top, the gases fall into the space between the barrel and the riser. The gases travel from here to underneath a thermal mass like a masonry bench to radiate heat into the room and onto your backside. At the end of the bench is an exhaust, so that the carbon dioxide and steam that is left over can escape.
The masonry bench part of the rocket mass heater can be made out of a variety of materials, like concrete, stone or brick, but perhaps the cheapest and easiest to obtain would be cob. Cob is simply a mixture of sand, clay, water, fibrous material like straw and earth. It can be shaped to fit any space and acts as an efficient thermal mass. As the hot air travels underneath the bench, the thermal mass absorbs the high amounts of heat and can slowly release the heat out into the room. This type of heat storage and slow radiation is extremely efficient, and many rocket mass heaters remain hot several days after the fire feeding them goes out. In fact, a well-built rocket mass heater can cut out 80-90 percent of the wood used in a traditional stove.
With a little research into the different styles of rocket mass heaters, the materials best suited to your area and how to best integrate one into your space, you can be saving time, money and wood with something you built yourself.

HOW TO BE ALONE by Tanya Davis
If you are at first lonely, be patient. If you’ve not been alone much, or if when you were, you weren’t okay with it, then just wait. You’ll find it’s fine to be alone once you’re embracing it.
We could start with the acceptable places, the bathroom, the coffee shop, the library. Where you can stall and read the paper, where you can get your caffeine fix and sit and stay there. Where you can browse the stacks and smell the books. You’re not supposed to talk much anyway so it’s safe there.
There’s also the gym. If you’re shy you could hang out with yourself in mirrors, you could put headphones in (guitar stroke).
And there’s public transportation, because we all gotta go places.
And there’s prayer and meditation. No one will think less if you’re hanging with your breath seeking peace and salvation.
Start simple. Things you may have previously (electric guitar plucking) based on your avoid being alone principals.
The lunch counter. Where you will be surrounded by chow-downers. Employees who only have an hour and their spouses work across town and so they — like you — will be alone.
Resist the urge to hang out with your cell phone.
When you are comfortable with eat lunch and run, take yourself out for dinner. A restaurant with linen and silverware. You’re no less intriguing a person when you’re eating solo dessert to cleaning the whipped cream from the dish with your finger. In fact some people at full tables will wish they were where you were.
Go to the movies. Where it is dark and soothing. Alone in your seat amidst a fleeting community.
And then, take yourself out dancing to a club where no one knows you. Stand on the outside of the floor till the lights convince you more and more and the music shows you. Dance like no one’s watching…because, they’re probably not. And, if they are, assume it is with best of human intentions. The way bodies move genuinely to beats is, after all, gorgeous and affecting. Dance until you’re sweating, and beads of perspiration remind you of life’s best things, down your back like a brook of blessings.
Go to the woods alone, and the trees and squirrels will watch for you.
Go to an unfamiliar city, roam the streets, there’re always statues to talk to and benches made for sitting give strangers a shared existence if only for a minute and these moments can be so uplifting and the conversations you get in by sitting alone on benches might’ve never happened had you not been there by yourself
Society is afraid of alonedom, like lonely hearts are wasting away in basements, like people must have problems if, after a while, nobody is dating them. but lonely is a freedom that breaths easy and weightless and lonely is healing if you make it.
You could stand, swathed by groups and mobs or hold hands with your partner, look both further and farther for the endless quest for company. But no one’s in your head and by the time you translate your thoughts, some essence of them may be lost or perhaps it is just kept.
Perhaps in the interest of loving oneself, perhaps all those sappy slogans from preschool over to high school’s groaning were tokens for holding the lonely at bay. Cuz if you’re happy in your head than solitude is blessed and alone is okay.
It’s okay if no one believes like you. All experience is unique, no one has the same synapses, can’t think like you, for this be releived, keeps things interesting lifes magic things in reach.
And it doesn’t mean you’re not connected, that communitie’s not present, just take the perspective you get from being one person in one head and feel the effects of it. take silence and respect it. if you have an art that needs a practice, stop neglecting it. if your family doesn’t get you, or religious sect is not meant for you, don’t obsess about it.
you could be in an instant surrounded if you needed it
If your heart is bleeding make the best of it

The Perth Wave Energy Project has demonstrated that the CETO 5 wave energy generators, developed by Carnegie Wave Energy Limited, are capable of using the movement of the ocean to provide electricity to a naval base near Garden Island in Western Australia. The site is the first commercial ocean wave energy installation. It has channeled zero-emissions energy from three CETO 5 units into a functioning power grid for 14000 cumulative hours.
And even as Carnegie puts its CETO 5 system to the test off Garden Island, work on a next-generation system is well under way. CETO 6 is so fundamentally different, it’s enough to make you wonder why the company bothered spending A$32 million to do the quite modestly sized 720-kilowatt CETO 5 project.
CETO 5 and CETO 6 do have a point in common: They both use submerged buoys – “buoyant actuators” in the argot – that drive pumps. Being submerged protects the seascape and keeps the actuators from the most violent ocean action, but a tradeoff is less energetic water.
With CETO 5, the actuators are tethered to pumps on the seabed. As the actuators move up and down in the passing waves, the pumps send high-pressure water through a pipe to an onshore power station where generators produce electricity.
But the many drawbacks of building and maintaining onshore-generation are evident in the rationale Carnegie gives for CETO 6, which won’t send water ashore and instead will produce electricity at the buoy and deliver it shoreside via cable.
The CETO 5 system consists of three 240-kilowatt units (the energy it produces is sold at an undisclosed price to a military base on Garden Island). The system was built with A$13 million in assistance from the government’s Renewable Energy Agency (ARENA). Ottaviano says Carnegie needs to scale up its system in order to become economical, and the company has apparently concluded that wasn’t going to happen with onshore power generation.
The “buoyant actuators” that are 11 meters in diameter for CETO 5 will be 20 meters in diameter for CETO 6, increasing generating capability to 1 MW apiece, Carnegie says. The plan is to deploy the CETO 6 system offshore from Garden Island, as with CETO 5, but about 11 kilometers out at sea instead of 3 kilometers, in deeper waters said to be three times more energetic.
