SOLAR STOCKS HAVE A GREAT WEEK

This week was the biggie with DJIA up 6.83%; NASDAQ +6.03% and this index rocketing 41.54%.

SUNSTOVE ORGANISATION

Five months without sales would have put most companies out of business. Luckily our overheads are minimal since we are Section 21 Non-profit. However, it was with great relief that we did eventually manage to persuade another moulder to make the cases.... but here lies the best bit of the story.

THE HISTORY OF HYDROGEN

One of the most serious gases we must use is Hydrogen - in our cars, buses, Space shots from the cape etc. I have been studying Hydrogen, Propane and many Bio-fuels and have found hydrogen to be the best, the oldest and the cleanest. I feel this alternative product is a win -win.

WHAT THE HECK IS A SMART GRID?

Nowadays we have several issues to face that are causing concern to humanity in general and the western world specifically. I don't think I need to repeat them here but basically they are environmental as well as geopolitical in nature. Hence, the old coal or oil burning power plant needs to be phased out and we must become much more efficient at generating and delivering electricity to end users or the costs become extraordinary over time.

WHY 2 BLADED ROTORS MAKE SENSE

One of the greatest advantages of two bladed rotors is the cost savings realized by the elimination of a blade. Although it can be argued that a teetering hub is more complex and costly than the rigid hub of a three bladed rotor, technological advances have reduced this complexity and cost. For example elastomeric bearings for the teeter hinge have eliminated the need for ball or roller bearings and the maintenance associated with these components.

ECO-SHEET COMPARES ENERGY SOURCES

The eco-sheet shows that there is no silver bullet solution. When looking at CO2 emissions only, it would be clear what options to take. However, this is not the only environmental consideration. Not preferring any particular method of electricity generation, the eco-sheet lists the main environmental impact categories and benchmarks them against the electricity generation mixes for the EU 25 and EU 15.

LEAD-CARBON: ALTERNATIVE ENERGY STORAGE

Lead-carbon batteries are different from other types of batteries because they combine the high energy density of a battery and the high specific power of a supercapacitor in a single low-cost device. The primary goals of lead-carbon research have been to extend the cycle lives of lead-acid batteries and increase their power.

RENEWABLE ENERGY SYSTEMS AND ENERGY STORAGE

The grid will need to be totally redesigned to integrate small generation inputs from PV, wind, biomass and other more sustainable system inputs, the majority of which will need to utilize energy storage to provide reliable energy reduction.

THINKING OUT OF THE BOX: SHELF-2-ENERGY

What do supermarkets do with their products when the expiry date has been reached? Surprisingly, there are only a limited amount of options. Belgian retailer Colruyt has found a sustainable angle: they convert it to green power.

25 WAYS TO CREATE A SUSTAINABLE SOCIETY

Jet travel has both been a time saver and a giant waste of energy. More fuel has been consumed in jet travel than by all the cars in the US combined. About 19.4 billion gallons of fuel are consumed by air travel within the US. Since these planes cannot use an alternative fuel, conservation is the only answer.

A CEDIA LOW-VOLTAGE INITIATIVE PROPOSAL

Somewhere in the mid 1980's, the NAHB Research Center in Washington was run by a guy I knew (whose name I can't seem to dig up) who had a wacky vision. His idea was to reinvent the way electrical power was distributed throughout the home. They called it Smart Home (not to be confused with the Disney movie of the same name or other stuff that uses that name now). I think it was the first use of the name.

BIOMASS PYROLYSIS

Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide. Depending on the thermal environment and the final temperature, pyrolysis will yield mainly biochar at low temperatures, less than 450 0C, when the heating rate is quite slow, and mainly gases at high temperatures, greater than 800 0C, with rapid heating rates. At an intermediate temperature and under relatively high heating rates, the main product is bio-oil.

Capturing Energy With Thermal Mass

The sun's heat passes through the windows and gets absorbed by dense materials like brick, stone, concrete, or rammed earth that will store the heat and release it later. Also called "Thermal Mass", these heavy materials serve to keep the house from overheating when the sun shines and later release heat when the sun is not shining.

CREATE A NEW ENERGY INFRASTRUCTURE

Our plan recognizes that fuel cells are being developed for a variety of applications and have matured at different rates. Certain applications are ready for early market support, while others still would benefit from additional research and development funding.

ENERGY YEAR 2008 IN A NUTSHELL

The global financial crisis dominated the news media in the second half of 2008. The crisis is certainly negatively affecting the sustainable energy market in the short term. On the other hand, the crisis has generated broad public demand for government investments that create employment and stimulate the economy.
