SimpleTech Goes Green with Bamboo Hard Drive

simpletech_redrive$150 isn't bad for a 500GB external USB hard drive, especially one that is guaranteed to fit in with your IKEA decor. SimpleTech's [re]drive isn't just about the looks, however. It is being sold on its environmental merits.

Made from bamboo (fast growing and renewable) and aluminum (very recyclable -- I worked in an aluminum warehouse one summer as the "scraps boy", so I should know), the [re]drive is also fan-free, dissipating heat through those metal sides.

The other power saving feature is an auto on/off function. This seems to be some kind of very low powered standby mode, which is good if you always leave things plugged in and switched on, but not so great if it tricks normally frugal folks into, well, always leaving things plugged in and switched on.

The packaging is also minimal: just a box with instructions printed on the inside and the USB and power cables taped into place. What's really nice, though, is that it is increasingly possible to go green and not have to opt for the wholemeal cardboard option. In fact, with looks like this you could probably buy the [re]drive and your friends wouldn't even know what a hippy you really are.

VIZIO preps hybrid PC/TV display, Eco HDTV

vizio-leaf-hdtvVIZIO today provided early details of three new display lines, including the company's first true hybrid display. Known so far as the VMM Monitor, the 26-inch LCD will have dual HDMI inputs but also DVI and VGA as well as RCA audio inputs for built-in 3W speakers. The TV maker promises a more desktop-capable design with a relatively thin bezel, a glass front panel, and the option of tilting or swiveling the image. VIZIO expects the VMM to appear in August for $450, or less than many stand-alone HDTVs at the same size. In its more familiar business, VIZIO also plans to launch an environmentally friendly 32-inch set. The ECO is capped to 720p but consumes about 65 watts less than a typical 32-inch model, or about 40 to 50 percent less than average sets. It also contains less toxic materials than full sets and even comes in thinner, recyclable packaging. The TV maker gives the screen a 2,500:1 contrast ratio as well as three HDMI inputs, dual RCA, and one each of component, S-video and VGA inputs. Shipments should start in October at an undetermined price.

A third introduction will see VIZIO debut the Java FHD line, which will give the company's smaller TVs a more upscale copper-and-black look as well as 1080p at sizes as small as 32 and 37 inches. Both sizes produce a 6,500:1 dynamic contrast ratio as well as three HDMI connections, dual component and RCA video inputs and one VGA input. The 37-inch Java FHD ships in September for $850, while the smaller panel ships on October 1st for $650.

Researchers squeeze more electricity from heat

exhaust

Researchers at Ohio State University have invented a new material that can generate electricity from heat in hot machine environments at an unprecedented rate.

The new material is called thallium-doped lead telluride.

The development could have a direct application for converting car engine exhaust heat into electricity, according to a statement from the university.

Using thermoelectric materials for generating power is not new. It is the group's improvements on this type of alloy that are newsworthy.

The group, led by Joseph Heremans, Ohio Eminent Scholar in Nanotechnology at Ohio State University, developed a material that is effective between 450 and 950 degrees Fahrenheit, the temperature range for most car engines.

"The material does all the work. It produces electrical power just like conventional heat engines--steam, gas, or diesel engines--that are coupled to electrical generators, but it uses electrons as the working fluids instead of water or gases, and makes electricity directly," Heremans said in a statement to the press.

Heremans' group has also more than doubled the efficiency rating with which the previously most efficient thermoelectric material could convert heat into electricity, from 0.71 to 1.5.

The invention's story is also an example of how scientific breakthroughs are really the culmination of many people's efforts over long periods of time.

Heremans credits a breakthrough development published in 2006 by researchers at Michigan State University on the quantum mechanics of thallium and tellurium with directly inspiring him after 10 years to try a new approach to producing this type of material. Testing of the new thermoelectric material was a collaborative effort between Heremans's group and scientists at the California Institute of Technology and Osaka University.

Details on the physics behind how the thallium-doped lead telluride was developed can be found in the journal Science.

Nissans to use ICP Solar battery chargers

Sunsei

Nissan cars sold in North America and Europe will feature solar chargers from ICP Solar, under a sales agreement announced Tuesday by the two companies.

The chargers will serve to keep the 12-volt batteries of new Nissans charged while they are parked on sales lots. Car dealers often have to replace batteries left dormant, even on new vehicles.

 With the new generation of cars including more and more electronics embedded such as GPS navigation systems, DVD player, cruise control, hands-free cell phones, and voice activation, the battery drain on new cars will become more of an issue for major automotive manufacturers and car dealers," said Tom Clark, Nissan's vice president of sales for the Americas, in a statement.

ICP sells consumer solar chargers between $50 to $1,350 for keeping the batteries of cars and recreational vehicles juiced up. Its chargers are included in Volkswagen Beetles shipped from Mexico.

Solar applications being explored by automakers include Toyota's reported plans to integrate Kyocera solar cells to power the air conditioning in Prius hybrids.

And Envision Solar's solar LifePod parking structures, which could charge up electric cars, are attracting attention in Hollywood.

Meanwhile, the sun-powered SolarTaxi from Swiss engineers hit the Bay Area last week during a promotional trip around the world.

The Montreal-based ICP Solar also sells solar cells integrated into the roof tiles of buildings.

The company announced in June that it will supply solar chargers for Sea Choice boating equipment.

Electric MINI will be in US customer hands in summer 2009!

mini-d-450-ftAt a breakfast meeting with MINI USA VP Jim McDowell this morning he was asked to elaborate on recently announced plans for a battery powered MINI. McDowell acknowledged that the US branch was caught somewhat by surprise with the announcement. Plans have not been finalized at this point as to whether the cars will be leased or sold, or how many will be built. What McDowell did say for certain is that electric MINIs will be on the road in the hands of regular customers in the summer of 2009, one year from now. He could not say if all those customers would be in California or if they would be made available nationwide. No specifications such as range are available at this time either.

Update: After the presentation, we talked to McDowell for a few more minutes and although he couldn't say what type of battery will be in the cars, he did say that MINI will make a further announcement later this year, possibly around the time of the Los Angeles Auto Show.

Texas gives green light to lots more wind power

wind-powerAUSTIN, Texas - Texas officials gave the go-ahead Thursday to the nation's largest wind-power project, a plan to build billions of dollars worth of new transmission lines to bring pollution-free energy from gusty West Texas to urban areas.

Texas is already the national leader in wind power, and wind supporters say Thursday's move by the Public Utility Commission will make the Lone Star State a leader in moving energy to the urban areas that need electricity.

"We will add more wind than the 14 states following Texas combined," said PUC Commissioner Paul Hudson. "I think that's a very extraordinary achievement. Some think we haven't gone far enough, some think we've pushed too far."

ElectraTherm installs first waste heat generato

ElectraTherm installs first waste heat generato

ElectraTherm installs first waste heat generato

CARSON CITY, NEV.: ElectraTherm, Inc. has installed its first commercial waste heat generator, which makes electricity from residual industrial heat that usually goes to waste.


Using patented heat and pressure recovery technology, ElectraTherm employs minimal heat (200 degrees F liquid) to generate fuel-free, emissions-free electricity at low cost: three to four cents per kW/hr during payback period, under a penny/kW hour thereafter.


Testing of the 50kW ElectraTherm Green Machine, installed at Southern Methodist University (SMU) in Dallas, Texas, by Gulf Coast Green Energy and ElectraTherm, has exceeded the companies' expectations, reaching output beyond its 50kW rating.


"ElectraTherm has unlocked the power of recycling the largest source of renewable energy in the U.S. - waste heat," said ElectraTherm CEO Richard Langson. "This technology has the power to increase electrical output at every fossil fuel burning power plant without burning oil, gas or coal, and without further pollution or damage to the environment."

 

According to some government estimates, electricity generated through waste heat recovery could surpass all other renewable sources, given the amount of waste heat generated in the U.S.


ElectraTherm estimates that its units have a subsidy-free payback period of three years or less, and company officials claim "the implications on the world stage of a modular, scalable (50-500kW output) unit making electricity from unused, accessible heat are huge."


The company's patented Twin Screw Expander enables the ElectraTherm Green Machine to do its work. The expander is one-tenth the cost of a turbine as the energy block, according to ElectraTherm. Since the energy block generally constitutes 30 to 40 percent of the cost of an organic Rankine cycle (ORC) system, the ElectraTherm Green Machine will cost approximately 30 percent less than turbine ORC systems.


The unit operates without gearboxes or the high end electronics required to synchronize a turbine to a generator. Inline process lubrication eliminates oil pumps, filters, separator tanks, parasitic loads and maintenance issues usually associated with lubrication. ElectraTherm officials say the technology reduces maintenance and extends the life of the ElectraTherm Green Machine compared to turbine-based energy solutions...

Crystal brings solar energy closer

Crystal brings solar energy closer

Crystal brings solar energy closer

AFFORDABLE solar energy for every household has moved closer to reality thanks to a ground-breaking discovery at the University of Queensland (UQ).

Professor Max Lu, from UQ's Australian Institute for Bioengineering and Nanotechnology, said researchers were one step closer to the holy grail of cost-effective solar energy.

"We have grown the world's first titanium oxide single crystals with large amounts of reactive surfaces, something that was predicted as almost impossible," Professor Lu said.

"The crystals absorb sunlight and convert it into electricity."

Prof Lu, who has been working on the project for the past 15 years, said the crystals were a cheaper alternative to solar panels.

He expects it to take up to 10 years for the technology to be commercially available.

Prof Lu said the crystals could also be used to purify air and water, and expected that to take about five years to commercialise.

The work was the result of a long-term international collaboration with Professor Hui-Ming Cheng's group from the Chinese Academy of Sciences...

Nintendo confirms injection of color for European DSes

Nintendo confirms injection of color for European DSes

Nintendo confirms injection of color for European DSes

For so long now, Europe has lived beneath a cloud, with a populace that is served by Smart Black, Crystal White, and Platinum Silver DSes. Where's the color, Nintendo? We know all about Noble Pink, but some of us are manly men, and it would hurt our fearful reputation to be seen with such a gentle shade of DS! Across the Atlantic, our North American friends have enjoyed those lovely two-tone models.

But no longer must our portable consoles lack vividity! Following much rumor and speculation, Nintendo has started e-distributing the advert you see to the right, featuring a rainbow of DSes (kind of an ugly rainbow, but a rainbow nonetheless). We've suspected this was real for a while, but it's nice to have some confirmation -- and some cheery color back in our lives.

In case you forgot, the Ice Blue, red, and green will all be here June 13th...
