Solar and Wind powered prefabricated office

Imagine you are building a temporary office in a remote area where connecting to the power grid is impossible or not practical. Or, for the 'kick' of it, you want a self-sufficient small office behind your backyard.

Why not consider a pre-fabricated one such as this, designed by Victor Vetterlein. In case you were wondering, this is an actual practical unit published at inhabitat, (well sort of) it's just a concept but it's workable):

Ready-made and easy to install

Power is obtained from wind and solar 

It is modular, so, you can add few units in series to build bigger home/office.

What is it

The designer calls it the MOSS, a prefabricated 13 foot octagonal structure intended for home office, powered by clean, renewable energy.


Energy efficient design concept

It has very minimal environmental impact while still providing a comfortable and professional working environment. The main structural frame is laminated tree farm wood and steel connection plates, while the interior consists of insulated panels for energy efficiency.

During daytime, lighting is provided by natural light via the provision of 'sunroof'.


Renewable initiative

The rooftop solar panels provide energy for electricity, as well as providing shade from the scorching sun during hot weather. Shading is achieved by slightly lifting the solar PV panels off the roof to provide ventilation. Small wind turbine is also fitted.

Flywheels

If you ever work in wood processing mill you’d be familiar with band-saws. The saws are attached to two big flywheels driven by AC motors. The wheels don’t need high initial torque to start rotating but once spinning, the band saw is capable of tearing apart even the biggest and hardest log.

Or, if you own a small diesel generator set – typically 5kVA to 10kVA – you’d be familiar with the tiring starting method. You need to spin a small but heavy flywheel to get the diesel engine going.

These are example of age old applications of flywheel. Let’s look at how flywheel is still relevant in today’s advance engineering. The following is an article I read from Daily Express:

What is a Flywheel?

A flywheel is a wheel that’s spun at high speed and used to store energy. They’ve been used for years in everything from traction engines to toy cars. But now Jaguar and Volvo want to see if they can be used to drive up fuel efficiency.

How would that work?

The car’s wheels would spin the flywheel, which would continue to spin until the stored energy was needed to drive the car. The stored energy would then be transferred back to the wheels via a transmission.

Are they currently used in cars?

Flywheels are an alternative to the Kinetic Energy Recovery System (KERS) most Formula 1 teams have been using last year. But although they’re permitted by the sport, no team currently uses them and neither are they found in road cars. F1 designers have worked on improving the technology but developing a flywheel is a headache; a great deal of stored energy can be lost to friction.

So what has changed?

F1 engineers have reduced the weight of flywheels using composite materials and cut friction by sealing the wheels inside a vacuum chamber. But it’s hard to make the seals between flywheel and transmission perfect. In F1, the seals only need to last for a short period of time. In road cars they need to be far more durable.

Is there a solution?

Engineering firm Ricardo has built a magnet-based system in which there’s no direct contact between flywheel and transmission. Jaguar is working with Ricardo and others on a flywheel, and Volvo is also looking into the technology for use in its vehicles.

Hope this will work towards energy efficient vehicles in the near future.

Energy Efficient Singapore

.
In my previous postings It Pays to Go Green and 5-Star Appliances and Rebates for You, I mentioned rebates of up to RM200 for energy-efficient appliances.

For the time being these rebates are for air-conditioners and refrigerators with 5-Star labels. This is one of the steps taken by Malaysia government towards wider usage of household appliances with high efficiency.

For Malaysia, energy-efficient equipment requirement is voluntary.

Singapore is a step further. The city state has imposed standards for minimum energy performance (MEPS) and it is now mandatory for exporters and manufacturers, including Malaysia, to comply with new standards if they want to continue selling these products there.

Among the specifications in these standards are types of goods, cooling capacity (in kW), minimum coefficient of performance, adjusted volume and maximum annual energy consumption (in kW).

What does that mean to our many manufacturing companies and consumers in Malaysia? A handful, both negatives and positives:

1. Higher production cost, product differentiation between export quality and 'local use'. Expect lower efficiency for local market. Remember, our carrots (rebates) are based on voluntary participation from manufacturers.
2. Accelerated acceptance of green technology. Manufacturers will now have to innovate to produce goods that are more efficient but cheaper in order to stay competitive.
3. Malaysia will have to come up with MEPS sooner than later. This should fulfill the government's pledge to reduce carbon emission.
   

My opinion: Incentives are good, it helps in many instances and no doubt it can spur the advancement of green technology on to certain feel-good level. But couple with regulatory measures, the pace of such growth will certainly be better.

FEW Willing to Pay to go GREEN

.

Only 1 in 5 Malaysian consumers are willing to pay more for eco-friendly products.

That is according to a global study by analysis firm Nielsen, and it's pretty low an appetite for greener products on our part.

According to Nielsen’s 2011 Global Online Environment and Sustainability Survey, 9 out of 10 Malaysian consumers show awareness and concern for environment pollution but 20% would actually be willing to pay more towards contributing to a greener world if it cost more to purchase environmentally friendly products.

There were 51 countries worldwide surveyed online and Malaysia ranked 9th in terms of consumer worries about the impact of air pollution and global warming. In this respect, Malaysians have shown good improvement compared to the last poll conducted in 2009. But being aware and concern is useless if they are not coupled with a commitment of sort, and this is where we are still lagging behind other countries.

What this means to the green industry is that this findings will have big implications for retailers and manufacturers looking to invest in environmentally-featured products to meet consumer needs.

I remember a quote by our State Minister of Tourism, Culture and Environment Datuk Masidi Manjun, "...that it is about time we start paying to view cultural shows and performances so that not only will our cultures be preserved but it will become a self-sufficient industry..." or thereabout, and I fully agree with him.

It is about time we pay a little more for eco-friendly products. Hopefully this, together with the incentives given by the government will bring down further the cost of producing such goods.

So there, for every five Malaysians out there, only one is willing to buy the more expensive green products. Could that person be you?
