How many bricks must be incorporated into the interior of the house?
A house is designed to have passive solar energy features. Brickwork is to be incorporated into the interior of the house to act as a heat absorber. Each brick weighs approximately 1.8 kg. The specific heat of the brick is 0.85 J/g·K. How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1.4 x10 ^3 gal of water?
1.4 x10 ^3 gal of water @ 3.784 litres / gal = 5.3 X 10 ^3 litres
=5.3 X10^6 millilitres = 5.3 X 10^6 grams
———————-
5.3 X 10^6 grams)(4.18joules /gC) = 2.21 X 10 ^ 7 joules / C
from water

Bricks:
(1800 grams)(0.85 joules/ gK)= 1530 joules per brick

Should poor countries sacrifice their economies to stop global warming and environmental issues?
This question comes after reading an article where China says that poor countries should not sacrifice their growth to the general concern about global warming and other environment issues. They have a point by adding that most of the green house emissions comes from the richest countries and that the effect of slowing their economy is far worst than the global warming effect. I belief that if we are able to travel to the moon and orbit the earth, we can find a better way to produce our goods and energy needs in a more efficient and cleaner way than today. Because of the fundings needed for research and development it needs to be done by the governments of the wealthiest nations. We as individual also need to play a part to be more efficient in the use of energy, water and goods. And this is not only is good for the environment but also for your own family budget.
Don’t get me wrong, I’m a total advocate for being environmentally conscious. In fact, I ride my bicycle to work to cut down on carbon emissions, dependency of foreign oil and the need for war to defend that type of energy – but I don’t think that any country should sacrifice their economy for ecology and I agree whole-heartedly with your explanation.
First of all, it’s not an either or issue. You do not either have an environmentally friendly country or a successful economy. You can have both. Holland has used wind energy for a long time. Recently Germany became the solar capital of the world (yes Germany, the place without a bunch of sun). I recently needed new light bulbs for my bedroom, and opted for the eco-florescent ones, because it doesn’t cost a lot more, and they make a lot of sense. Walmart enclosed their refrigerators and used skylights better to reduce their energy usage by 20% or more. Shanghai is even building “green” complexes with commercial and residential together so residents use less fuel to get to the store and back.
When I look at the problem, it’s not an issue of killing an economy, it’s an issue of adopting best practices. Best practices include designing better buildings that are multifuncional and more energy efficient. Best practices includes placing retail and commercial space near residents who will shop and work there. Best practices include producing wind, solar, wave, and geothermal energy close to where it will be used. Best practices include not eating a 3000 mile salad.
Being environmentally concious is not something that you do by going about big projects. It’s about living life a little bit smarter than we used to.
On a side note, I think that there are better ways to invest the world’s money than to combat global warming. Check out this link for a nice 19 minute discussion of the topic. Very intelligent.

As more money becomes available for the development of energy saving products, there will also be an enormous demand for marketing specialists that can help customers learn about these items. Today, a wide range of internet marketing strategies can help you build a website that will make it easy for you to begin selling these products as they become available. In most cases, you may even find that focusing on a diverse range of environmental issues will make it easier for you to increase search engine rank, as well as a following of viewers that will easily convert to customers.
If you are aware of one environmental issue, you are also aware of dozens of others. As an example, if you are concerned about global warming, you may also have an interest in an endangered species that is subject malicious slaughter by rogue nations, or those under their protection. Irregardless of whether you want to promote solar cells, or hybrid cars, you need to ensure that the nation of origin has moral standards that are compatible with those of watchful environmentally conscious consumers. When visitors see you promoting products from nations that they associate with environmental mayhem, they will shun your site and look for business owners that truly share their ideals.
For the most part, you will find that internet marketing strategies related to green products will focus on creating peace of mind. You may find it necessary to carry disclaimers on your site about the origin of your products, as well as why you feel it is important to refrain from purchasing products from companies that you will not promote. Without a question, if you hit on a popular subject, some buyers will spend more money at your site, as opposed to buying from a competitor that is less aware of certain environmental issues.
Typically, you will find that basic internet marketing strategies can be adapted to suit almost any product. As an example, an email campaign can be as easily used to to promote solar cells from Japan as it can solar cells from Europe or the United States. Unfortunately, if your email reaches a potential consumer that is disgusted with the nation where your products originate, they will most likely shun your site. Therefore, when you seek to promote green products, it is very important to be aware of how your customers view what initially appear to be unrelated environmental and humanitarian issues. You may even find that clearly stating your feelings and actions related to these issues will help you create compelling, and powerful internet marketing strategies.
