Mission to M.A.R.S.!

mars

The Magenn Air Rotor System (MARS) is a new generation of wind turbines with cost and performance advantages over existing systems. 

MARS is a lighter-than-air tethered wind turbine that rotates about a horizontal axis in response to wind, generating electrical energy. This electrical energy is transferred down the tether for consumption, or to a set of batteries or the power grid. Helium sustains the Magenn Air Rotor System, which ascends to an altitude as selected by the operator for the best winds. Its rotation also generates the “Magnus” effect. This aerodynamic phenomenon provides additional lift, keeps the MARS device stabilized, positions MARS within a very controlled and restricted location, and finally, causes MARS to pull up overhead to maximize altitude rather than drift downwind on its tether. mars2

The Advantages of MARS over Conventional Wind Turbines are: (1) low cost electricity – under 15 cents per kWh; (2) bird and bat friendly; (3) lower noise; (4) wide range of wind speeds – 2 to more than 28 meters/second; (5) higher altitudes – from 200 to 1,000 feet above ground level are possible without expensive towers or cranes; (6) fewer limits on placement location – coast line placement is not necessary; (7) ability to install closer to the power grid; (8) mobile and; (9) ideal for off grid applications or where power is not reliable. mars3



Tim Hortons Should switch to Earth cups!!

earth_cups_with_lids

    *  Earth Cup™ is made from renewable resources, is 100% compost able and petroleum free, all which make this cup very earth friendly.

    * Most hot cups are coated with Low Density Polyethylene (LDPE), a petrochemical plastic. LDPE is non-renewable and non-compostable, making the only methods of disposal; litter, land fills or incineration. Earth Cup™ is coated with earth friendly bio based material that uses less energy and significantly less greenhouse gas footprint.

    * Earth Cup™ meets the ASTM 6400 composting standard and is acceptable at over 45 composting facilities in North America.

    * Earth Cup™ can be coated one side for hot cups and two sided for cold beverages.

          o Earth Cup™ hot cups are suitable for hot coffee, tea and other hot beverages.

          o Earth Cup™ 9 oz water cups are coated on both sides and are suitable for water, soda and other chilled beverages.

    * Earth Cup™ hot cups stock sizes are 10, 12, 16 and 20 oz.

          o all hot cups fit one size Tater Ware™ sippy lid

          o 24 oz cups will be available in December.

    * Custom print using either flexo or off set print is available hosting up to five colors using soy based inks (minimum order is 50,000 per size).



Make this Handy Heater with an old Flower Pot

Written by Sarah Nagy

Kandle HeeterToday is a cold, wet dreary day. Which inspired me to dig the Kandle Heeter out of the garage.

kandle-heeter2

Parked next to my mouse, this little device brings the temperature of my 8×12 office up from shivery to cozy – not quite enough to take my lovely handknit wool socks off, but a great antidote against a dreary January, and a definite cat magnet.

How it works: That top terracotta pot is actually a nest of several, spaced with metal bolts. Heat rises from the candle and then absorbs into the ceramic, which is a high ‘thermal lag’ material. High thermal lag materials are dense and heavy – tile, concrete, water – all of these store heat well. The pots won’t hold it forever, but they concentrate it, slowing down its exodus to the ceiling. They keep the heat near my mouse hand – which definitely increases my productivity!

The developer says a 3″ dia. by 3″ ‘dollar store’ candle will yield about 50 BTUs an hour, for a total of 1000 BTU. I get about two days per candle, so that’s 0.50/day. If all my winter days were wet, cold, and in need of paraffin cheer (sum total of mid-Dec thru March = 105 days), that’s about $50 for a heating season. And it smells nice.

Granted, I live in mostly sunny Northwest Florida, so my heating bill is pretty small compared with snowy places. But this one with the silly name is one of those ‘value added’ ideas – if I’m going to burn a Christmas gift candle, I may as well get full value.

(Check out their other nifty ideas: using an incandescent light bulb instead of a candle, and other open-architecture common-sense energy concepts.

UPDATE: Here’s a podcast interview with inventor Doyle Doss. (Ed. note: Max tells us the podcast isn’t there anymore, but he’s reposted it at http://www.thelindbergreport.org.)

NEW LED’s for Florescent Bulbs

t_8_rp_22 LEDs are now available to replace Incandescent, Fluorescent and Neon lighting

These LED tubes fit into a T8 fluorescent fixture. The brightness is similar to a 40W T8 bulb, but ours uses 14W of electricity. You save 26W per bulb. Now times that with every fluorescent light in your building and the KW savings is staggering.

We can offer a beautiful warm white color that will be almost the same as an incandescent (Edison) bulb. These tubes will last about 17 years if used 8 hours a day.

Features

The savings is normally between 70-85% on electricity.

There is no hazardous waste.

No mercury.

No gases.

All environmentally friendly.

LED diodes quantity – 300 PCS (driverless)LED Wave – 3700k

LED Color – White = 5500

Kelvin – warm white = 3700Savings

Based on $0.06 kwh, 4-foot, 40W fluorescent tube x 80,000 hours/the lifespan of the LED light.1 small store with 60 lights would save over $10,000!

60 lights with $156.00/each = total savings = $9,360.00 .Technical Specifications

7.5W & 14W(no driver)

Tube working voltage

110V AC

The Return on Investment for either of these solutions is less than one year.



Even before the protester is removed, even before the public safety is secured the advertising goes up

 

The ongoing “tree-sit” protest to stop construction of an athletic training center on the U.C. Berkeley campus finally came to a conclusion on September 9, 2008, when the last tree-sitters came down from the one remaining tree. The scene attracted a huge crowd of sympathizers, detractors, onlookers and media.

 

A recent legal ruling had cleared the way for the university to begin construction after a seemingly interminable series of delays which lasted over a year and a half. Within hours of the ruling, campus work crews felled all but two of the disputed trees which had occupied the work site — one that was to be transplanted elsewhere, and the other (a redwood) which housed the last four tree-sitters. A few days later, on September 9, after negotiations failed to convince them to come down of their own accord, the police had no choice but to bring them down whether they liked it or not. The stage was set for the final act.
