Nanocrystaline Cellulose – Its nature’s way of telling you

This isa  pretty interesting piece. It implies that most of the complicated and expensive atom level experiments to create nanotubes and other “nanostructures” were something of a waste of time. They also imply that the next advance in nanotechnology maybe finding ways to form, market and install new nanostructures at the real world level. In the literature it is stated that this form of cellulose can be both an insulator and a conductor so it would be nice if someone came up with a shielded electrical cable that could be used in the housing market, for instance. I have included 2 references for clarity’s sake.

Nanocellulose Is No Small Thing

Trees could become part of electronics, medical devices, and military gear

 

For centuries, the forestry industry has produced paper and lumber. But what if trees could be transformed into an entirely new set of products, ranging from electronic sensors to biomedical implants to military protective gear?

The idea isn’t as improbable as it sounds. Researchers are studying a nanoscale material that can be extracted from trees and, in some forms, is about as strong as Kevlar. Called “nanocellulose,” this lightweight material is composed of bundled sugar chains from the cell walls of wood. Researchers can extract nanocellulose by grinding pulp or using chemicals to break it down into tiny particles. At such small scales, the material has fewer defects, making it stronger. One type of nanocellulose particle, called cellulose nanocrystals, is especially tough because the sugar chains are arranged in a highly ordered structure.

Researchers envision a huge array of applications for nanocellulose. It could partially replace fossil fuel–based products such as petroleum-derived plastics and might be cheaper than other high-performance nanoscale materials. Clear sheets of nanocellulose might be useful for windows or electronic displays. Studies have shown that some forms of cellulose are piezoelectric, meaning they generate an electrical signal when deformed, so nanocellulose-based sensors could potentially monitor structures such as bridges for signs of stress. Nanocellulose food packaging could block oxygen permeation and keep the contents from spoiling, while nanocellulose scaffolds implanted in the body might aid bone regeneration. And at the U.S. Army Research Laboratory in Maryland, researchers are investigating whether nanocellulose-reinforced materials could better protect soldiers on the battlefield.

A Bike Made Out Of Cardboard – This is an amazing design

Finding a design as cool as this is like finding a reason to live. Like being given a sack full of candy. It just lights up my life and gives me hope. Hope is a scarce commodity these days what with the drought and the drum beats for war against Iran. Still this is so cool.

This $9 Cardboard Bike Can Support Riders Up To 485lbs

Innovation By Design

It’s 100% recycled and very lightweight, with a frame that’s stronger than carbon fiber.

Izhar Gafni has designed award winning industrial machines for peeling pomegranates and sewing shoes. He’s also a bike enthusiast who’s designed a lot of carbon fiber rigs. But one day, he’d heard about someone who’d built a cardboard canoe. The idea drilled its way into his consciousness, and ultimately, led him to create a cardboard bike called the Alfa.

The Alfa weighs 20lbs, yet supports riders up to 24 times its weight. It’s mostly cardboard and 100% recycled materials, yet uses a belt-driven pedal system that makes it maintenance free. And, maybe best of all, it’s project designed to be manufactured at about $9 to $12 per unit (and just $5 for a kids version), making it not only one of the most sustainable bikes you could imagine, but amongst the cheapest, depending on the markup.

But as the above video documents, the design process was arduous. Engineers told Gafni that his idea was impossible. Yet he realized that paper could be strong if treated properly. As in crafting origami and tearing telephone books, he explains, “[if] you fold it once, and it’s not just twice the strength, it’s three times the strength.”

Peak Oil, Transition Towns and Community Energy Systems

When I saw this I was in “Holy Cow” mode. I mean it covers so much of what CES would like to accomplish. Sadly it is in Britain. So we will just have to soldier on.

Community Power in Lewes
Posted on September 10, 2012

Ouse Valley Energy Supply Company, or Ovesco as it is commonly known, is a powerful inspiration for enthusiasts of community renewable energy. In August I was given a guided tour of Ovesco projects by Chris Rowland, which you can see here, and then filmed Chris explaining the origins of Ovesco and outlining some of their projects. You can view the second film here.

Standing on a hill above Lewes you can not only see the solar PV installations completed by Ovesco but also arrays of panels inspired by their projects. The local football club, the leisure centre and many local homes, have all followed the example of Ovesco. Other sites are looking to follow and there are also plans for community wind and hydro-electric schemes.

The Ovesco website is a rich source of information and links for community renewable energy projects and is well worth a visit.

Below is an edited version of an article on the OVESCO website.

Power to the people of Lewes

Green Investments Pay – Not according to the FHFA

This is an interesting Blog and an interesting post. I am no good at posting videos so:

http://legalplanet.wordpress.com/2012/09/09/are-pace-financed-residential-energy-improvements-capitalized-into-home-prices/

Are PACE Financed Residential Energy Improvements Capitalized into Home Prices?

September 9, 2012

The FHFA believes that an unintended consequence of obtaining a PACE loan is to increase the risk of mortgage default.  The FHFA’s  logic is that if the green investments are not capitalized into home prices then the home owner’s equity decreases as equity =  sales price – debt owed.   Under these assumptions, the green investment doesn’t raise the sales price but does increase the debt owed. My recent research convinces me that this pessimism is false.  Here is  My letter to the FHFA. Here is my July 2012 peer viewed paper on solar panel capitalization effects in San Diego and Sacramento   dastrup-zivin-costa-and-kahn .

We need more regulatory scholarship focused on empirical work and hypothesis testing.  I have an incentive to say this because that is what I do.

Power From The People – How to community finance alternative energy

I do not know whether this is the way of the future. It sure claims it is.

http://peakoil.com/publicpolicy/how-to-organize-finance-and-launch-local-energy-projects/

How to Organize, Finance, and Launch Local Energy Projects

Is it possible to “relocalize” energy? This is a critical question that must be addressed if we are to achieve true global resilience.

In our brand new book (September 4, 2012), Power From the People, energy expert Greg Pahl decisively argues that the answer is YES.

Power From the People is the second book in our Community Resilience Guides series, The book illustrates how communities across the country are already generating their own energy at the local level. From citizen-owned wind turbines to co-op biofuel producers to community-wide initiatives combining multiple resources and technologies, Pahl outlines the steps necessary and plan, organize, finance and launch community energy projects.

The book showcases over 25 real-life examples of local energy projects, offering a range of challenges and solutions that can be adapted and reapplied.

America 9th In The World – I am not sure whether I believe this or not

ACE3 rarely ever gets very much wrong.  But the idea that the UK was the most efficient country in the world and the USA was 9th? There is something very wrong about that.

http://www.energycircle.com/blog/2012/08/15/us-takes-9th-place-energy-efficiency-out-of-12

U.S. Takes 9th Place in Energy Efficiency! (Out of 12).

By Will – August 15th, 2012

A new report from the American Council for an Energy Efficient Economy (ACEEE) ranked the energy efficiency of the world’s 12 largest economies. The U.S., unfortunately, ranked 9 out of 12.

So while we were out dominating at the Olympics, we were quietly slipping behind on a metric that, if improved, would yield a substantial benefit  for our country — economically as well as environmentally.

So how did we do on the specifics?

  • 9th overall in energy efficiency
  • 9th in terms of “national effort” in energy efficiency
  • 6th in industrial energy efficiency
  • 4th in building energy efficiency
  • 12th in transportation efficiency

With our penchant for gas guzzlers and the unpopularity of public transportation over here, it’s easy to see how we came in dead last in transportation.

But a shimmer of hope there is the 4th place ranking we got in building energy efficiency — our best category, and not all that shabby really. (We would have almost gotten a medal if building energy efficiency were an Olympic event.) While we’ve previously lamented our slow progress in implementing energy efficiency in buildings, and have shaken our heads as federal tax credits have been cut and legislation aimed at improving energy efficiency has stalled, it looks like we’re actually doing okay in the field of building efficiency compared to the rest of the world’s developed countries.

Solar Power In New Mexico – What better of a place to set up shop

Yes I know about the fire at the Chevron Plant in the Bay area and what that adds to the idea that the oil and gas industry is purposely taking gasoline processing capacity offline as demand for gasoline falls to keep prices high. But solar is so much more peaceful and zen like.

This type of progress is just stunning. We are on the way to becoming a renewable country. Now if the rest of the world will follow suit.

New Mexico’s largest solar plant opens in Carlsbad

Posted at: 09/22/2011 6:10 PM | Updated at: 09/22/2011 6:16 PM
By: Joe Bartels, KOB Eyewitness News 4

Carlsbad officials unveiled the largest solar power project in New Mexico on Thursday.

Three of the five solar power plants in Southeast New Mexico went online, feeding enough electricity over the next 20 years to power almost 200,000 homes.

Eddy and Lea counties added the additional energy source to their already impressive portfolio.

“We have, of course, nuclear, we have bio fuels being produced down here, a vibrant oil and gas industry that’s doing fantastic and now we have solar,” said John Waters of Eddy County Economic Development.

The 100 acres of photovoltaic panels will track the sun’s movement in the sky for the next 20 to 30 years.

It’s all part of a plan to create clean, renewable energy and jobs.

“What we have is a facility that employed people for a significant amount of time, and will continue to do so over the next 20 to 30 years,” said Robert Reichenberger, Sun Edison spokesperson. “These panels and this facility are expected to last that long so we will continue to need people on the jobsite to monitor the project.”

Out of the three power plants online, two of them are in Jal and one is in Carlsbad.

The two offline – in Eunice and Monument – are expected to be generating power by the end of 2011.

“It shows we’re ahead of the rest of the state in this type of energy production and we like to think of ourselves in Southeastern New Mexico, particularly Eddy County as being a major contributor to the energy industries across the country,” said Waters.

Solar Power Plants In China – They are beating us like a broken drum

Because of the power of the coal industry and the oil industry, China is so far out in front of American that it is not even funny. It so pitiful that we let all of this happen under George Bush’s watch. He built the biggest wind farms in Texas and then dropped the ball at the Federal level. We never may actually be able to catch up.

Even In Botswana They Like Solar – Though this one is smaller than the first proposal

About 2 years earlier there is evidence in the literature that the Botswana government let bids for a 200 megawatt facility. So why this one is for a little over a meg., I got no idea. And there are no pretty pictures either.

News Name Solar plant boosts relations with Japan
Author BY LETTY MASUNGA
Date 17-02-2012

BG correspondent The P85 million 1.3MW Photovoltaic Power station in Phakalane will not only serve to diversify the country’s energy sources but also boost the country’s economic relations with Japan. The Japan-sponsored clean energy plant is expected to be complete in September this year. The plant is part of government’s investment in the energy sector. Speaking during a progress tour of the Power Station on Wednesday, Mineral and Water Affairs minister, Ponatshego Kedikilwe said: “This arrangement will not only boost our economic relations with Japan but will be beneficial in the diversification of energy sources,” as it will lessen the pressures of rampant energy shortage. Phillimon Dhafana, the Manager of the Planning and Projects in Rural business unit from Botswana Power Corporation, explained that the power plant would generate uncultivated solar power. Dhafana told the Botswana Guardian that, “our country experiences plenty of heat that these power plant will harness and convert to solar energy that will benefit the whole country.”

Dhafana said the difference between Morupule power station and this new project is that the solar power plant produces clean energy while the Morupule plant emits coal gases, which destroy the greenhouse. The power station is expected to be complete in September.
