Track the sun for home lighting

Sunday, January 4th, 2009

sun_track.jpg

Have a room in your house that really could benefit from some sunlight? Build a Suntrack to reflect light in as long as possible. The two axis motor set up is built from a couple of  satellite dish positioning motors with the control electronics removed. The whole thing is controlled with a PIC 18f2520.  Once calibrated, it will reflect the sun into your room, updating every twenty seconds. While this may not be the most efficient way of lighting a room, it is a cool way to do it if you absolutely must have sunlight. We can’t help but wonder if there would be a way of using a solar powered system to do this to save energy. Could this possibly be done using BEAMhead” circuit?

Nation’s First ‘Underwater Wind Turbine’ Installed in Old Man River

Tuesday, December 23rd, 2008

The nation’s first commercial hydrokinetic turbine, which harnesses the power from moving water without the construction of a dam, has splashed into the waters of the Mississippi River near Hastings, Minnesota.

The 35-kilowatt turbine is positioned downstream from an existing hydroelectric-plant dam and — together with another turbine to be installed soon — will increase the capacity of the plant by more than 5 percent. The numbers aren’t big, but the rig’s installation could be the start of an important trend in green energy.

And that could mean more of these “wind turbines for the water” will be generating clean energy soon. (more…)

IS IT GREEN?: ZipCar

Wednesday, November 19th, 2008

One of the great perpetrators of the United States’ wastefulness is urban sprawl, which leads to SOV (single occupancy vehicle) disorder. Many Americans drive to work, and we usually don’t carpool. Beyond driving to work, we use our cars for other things – soccer practice, forgotten items at the grocery store, and trips across our giant country. It doesn’t need to be that way. If we could break ourselves of this habit of hyper-convenience, we could have better bike lanes, rail, and bus systems. Or we could share our cars. Zipcar is an innovative car sharing service that prides itself upon its convenience and accessibility. We recently caught up with Zipcar spokesperson Lesley Neadel to ask a few questions about the company’s green cred.

Solar Hybrid Yacht Shows Electricty and Water Do Mix

Saturday, November 15th, 2008

Who says water and electricity don’t mix? The world’s first solar-electric-diesel hybrid yacht will have you impressing the greenies at the Yacht Club and sailing the seas in style.

The Island Pilot DSe Hybrid catches rays with a 6.8 kW solar array that’ll get you to Margaritaville and back at 6 knots with zero emissions. But if the sun ain’t shining in Cocomo, you can crank up the Steyer Motors parallel hybrid system that mates a 75-horsepower diesel engine and a pair of 36-horsepower electric motors powered by a 20-kilowatt-hour battery pack.

The 40-footer was a hit at the recent Fort Lauderdale International Boat Show, where it was one of several green vessels and gadgets that ranged from the Epower Marine Calypso Classic electric fishing boat to the 100 percent recyclable propellers made by Piranha Propeller.

But it was the $600,000 DSe that really wowed the crowd.

The DSe can run for as long as two hours on battery power. Kick on the diesels and she’ll cruise at 13 knots while charging the battery pack through a pair of 25-kW generators. Run the diesel engine and electric motor in tandem and she’ll hit 15 knots. (more…)

Piaggio Unveils a 141-MPG Plug-In Hybrid Scooter

Thursday, November 13th, 2008

Italian scooter-maker Piaggio has unveiled a plug-in hybrid three-wheeler it says will get up to 141 mpg and could be on the road as early as next year.

The gas-electric version of Piaggio’s funky but fun MP3 scooter uses a parallel hybrid system much like that in the Toyota Prius but advances the technology by adding an electrical cord. Although Toyota, General Motors and several other automakers are developing cars that can be charged from a wall socket, Piaggio’s timeline, if met, would make it the first in the world to mass-produce a plug-in hybrid.

In this season of specters and spooks, what could be scarier than a steel-winged robotic spy plane shaped like a bat? The aptly named COM-BATis a six-inch surveillance device that is powered by solar, wind, and vibrations. The concept was conceived by the US military as a means to gather real-time data for soldiers, and the Army has awarded the University of Michigan College of Engineering a five year $10-million dollar grant to develop it.

Smart Meter Technology Deployed for Heart Patients

Sunday, November 9th, 2008

GainSpan has a chip that can curb energy consumption in the home, and notify your doctor if you’re about to have a heart attack.

The company has produced an energy efficient WiFi chip that it hopes to install in dryers, electrical meters and other devices in the home. The idea is that utilities and consumers will shut off and/or power down appliances with wireless signals remotely to curb electricity consumption.

GainSpan is currently working with manufacturers to insert its chip into cold storage units, meters and other devices. Hitachi Plant Technologies, the industrial technology arm of the Japanese giant, makes sensors incorporating GainSpan’s chips. The company was spun out of Intel.

Snow-Based Cooling System

Sunday, October 26th, 2008

The transport ministry aims to introduce a system in fiscal 2010 to provide 30% of the cooling energy at New Chitose Airport terminal building in summer from snow collected in winter, ministry officials said Tuesday.

A regional office of the Ministry of Land, Infrastructure, Transport and Tourism collected snow last winter at the airport and confirmed that it could retain up to 45% of it by September by covering it with heat-insulating materials. It has concluded that the snow could be used to chill the liquid used in the airport’s cooling system in summer and that doing so would lead to a cut of some 2,100 tons of carbon dioxide emissions annually, according to the officials.

Going Green and Burning Rubber in a CNG Mustang

Sunday, October 26th, 2008

naturalgas_mustang.jpg

Going green doesn’t mean giving up wheel-spin-inducing, tire-shredding performance, as this 300-horsepower natural gas-burning Mustang GT proves.

German natural gas conversion specialists Green Autogas teamed up with tuning haus Rollin on Chrome to prove “green” isn’t synonymous with boring. Together they tweaked the Mustang’s 4.6-liter V8 to run on propane natural gas, then installed a body kit, carbon-fiber hood and 22-inch wheels. The lime-green paint is waaay over the top and we’re not wild about the wing, but Green Autogas is to be commended for the effort.

So is the car as green as it looks?

The CNG engine produces about 20 percent less CO2 than the gasoline engine it is based on and 95 percent less nitric nitrogen oxide (NOx) than a typical diesel, according to Motor Authority. It’s tough to put that in perspective, though, because no one’s provided fuel economy data or a cost-per-mile comparison with the stock ’stang.

Autogas isn’t the first outfit to build a green Mustang. The BioConcept Mustang built by German tuners FourMotor used a biofuel-burning 2.0-liter turbodiesel that produced 280 horsepower and 368 foot-pounds of torque. The car was good for 152.2 mph and raced in the 24 Hours of Nurburgring.

As for the Autogas CNG Mustang, we’ll park it next to the sweet natural gas-burning Porsche 356 clone French boutique automaker PGO produces.

HumanCar Powered by Human Energy, Not Ethanol

Tuesday, September 30th, 2008

Charley and Chuck Greenwood, a father-son combo, think they know the secret to the future of cars: rowing.

And they founded their company HumanCar to prove that human energy, not biofuels, is the gasoline of the future. Their Imagine_PS car seats up to four in a low-slung chassis; the passengers get to help row the lightweight car.

Think of it as an ergonomic, efficient and sneaker-saving Flintstone’s car for an oil-free future. The front two ‘drivers’ get to steer, which is done with a talented and coordinated lean.

“Body steering comes from the hips,” CEO Chuck said. “It’s just like a properly performed ski turn.”

But revolutionizing steering is not the point of these Oregon entrepreneurs. “It’s about thinking about days per life versus miles per gallon,” CEO Chuck Greenwood said.

When powered by four people rowing, the car will go about as fast as the ‘drivers’ would on bicycles, on average.

But, that’s only if they were driving in a flat city like Chicago, where the car is currently on display for two weeks during the Wired NextFest future-tech expo in Millennium Park.

For hillier locales or higher speeds, there’s electric assist motors and regenerative brakes that funnel the vehicle’s momentum back into the batteries.

The Greenwoods plan to sell Imagine_PS as a Neighborhood Electric Vehicle, a state-by-state designation that frees it from requirements such as air bags and in some states, even the need for a licensed driver or insurance.

But to qualify, the top speed will have to capped at around 20 mph — though the Greenwoods say the chassis can easily handle sports car speeds in excess of 100 mph.

Hear that, hot rodders?

Though not yet for sale, advanced models of the Imagine_PS for corporate campuses will be available soon for $35,000 to $50,000, while the consumer model is slated to be be priced at $15,500.
