Fly Ash Concrete – Eco Friendly And Lasts Longer

Thursday, October 1st, 2009

Fly AshMost concrete produced is from portland cement, and it consumes more energy and pollutes more than any other industry including steel and plastics.  It contributes 5-8% of all greenhouse gases just by itself, and prduction is growing at about 5% annually.

Fly ash is a waste product of a coal combustion plant.  It is the non-combustible portion of coal that used to be released into the air before through the smoke stack before the government put more strict regulations on what can be release into the atmosphere.  The particles themselves are spherical and smooth and more fine than cement particles. read more »

Combining The 5 Best Solar Technologies

Monday, October 27th, 2008

I know there is a lot of red tape and patents that would make this impossible in the near future, but what if we could combine the 5 most effective solar technologies in the world and create a super solar collector that would be able to take care of our energy needs? I know it kinda sounds like Captain Planet, but I don’t think its too far out of reach. A few criteria have been taken into consideration. The super solar cell must be efficient, drive the cost down, and solve the problem of solar power at night. I know its a long shot, but here are my five picks.

1. In terms of the shape of the cell, I think Solyndra has it right in making cylindrical solar cells. They don’t have to be mounted at an angle. They can be mounted flat which saves installation costs and makes them more durable read more »

Beam Energy From Space

Monday, October 20th, 2008

Oil prices are indeed coming down, but that is no reason to stop looking into renewable sources of energy. Oil will only last a finite amount, and the plunging oil prices over the last few months is only temporary. Our demand for energy is not one that will stagnate for long. We consume more oil than anyone on the planet and the demand will get larger over time.

There are problems with the current renewable energy sources we have now. Wind energy requires large plots of land and are noisy. Geothermal and tidal is specific only to location and cannot be used in a wide scope. Nuclear doesn’t pollute the air, but we have to deal with the radioactive waste. Solar can only be used read more »

Black Silicon Could Revolutionize Solar Industry

Monday, October 13th, 2008

Physicist, Eric Mazur, and his graduate students were financed by the Army Research Organization to explore catalytic reactions on metallic surfaces. In the 90′s, Mazur was afraid that the research money would soon stop so he wrote in a new direction into his research proposal, and to this day doesn’t know why he did it. It wasn’t until more recently that he asked a graduate student to pick up on the research. The graduate student then shined a powerful laser on a silicon wafer’s surface and then on a hunch exposed the wafer to sulfur hexafluoride, a gas used by the semiconductor industry to make etchings for circuits.

The result was a black silicon wafer, but under an electron microscope, the surface was riddled with “spikes.” Much like many accidental discoveries, the researchers read more »

Hooray Sewage!

Friday, October 10th, 2008

Sewage seems to be in the news quite a bit in the last few weeks. This time scientists have figured out a way to produce cheap hydrogen using the stuff we flush down the toilet. Oregon State University researchers have figured out a way to produce hydrogen at a lower cost than conventional electrolysis.

The technology works by putting microorganisms from sewage to an anode’s surface and then degrading the waste in the swage using a battery. The waste decomposes and leaves protons that move to the cathode and combine with electrons producing hydrogen. It is predicted that this technology will drive the cost of hydrogen down to read more »

Prince Charles Attacks Modern Green Architects…Again

Thursday, October 9th, 2008

I came across and article on the Telegraph. At first I was bothered that some snooty Englishman that lives in a castle far removed from the likes of me would make a comment about architects making buildings green. To put some perspective on this, about 20 years ago, he vehemently opposed the Sainsbury Wing extension at the National Gallery in London and described it as a “monstrous carbuncle”. Now I don’t know what a “carbuncle” is being on this side of the Atlantic, but I would say that it doesn’t sound positive. read more »

Ocho House

Wednesday, October 1st, 2008

This house was designed by Feldman Architecture and is located in the Santa Lucia Mountains of Carmel, California. It was completed 4 years ago, and last year it received and award from the American Institute of Architects for its use of passive solar heating and living roofs which make for a very efficient house.

I really like the mixture of materials and that the home, although modern, is not cold. It has a very inviting feel to it with all the light coming in.

From the architects: read more »
