MillerCoors: How Green Beer Is Made. Solar Water Heater Design - Micro Brewery - Cheresources.com Community. Isn't it great to see a question presented to the forum where the originator has done some engineering to get things started? My thanks. I may have missed something but I can't see in the analysis by Sorter, et al, where there has been account of heat loss from the system in question. The implied assumption that I draw from their paper is that they've assumed heat losses to be zero.
I would expect the heat loss to increase with a reduction in ambient temperature and given that your ambient appears to sit at about 10°C, then this is an issue to be wary of. Sorter hasn't really explained the methodology used for deriving the collector area equation, which immediately piques my concern. Unless you've chosen the same mechanical design, then you're potentially making an incorrect application of Sorter's design equation. I did a quick search and found the following paper by Bolaji:Bolaji Paper Notable differences between Bolaji and Sorter:1.
Beer and Climate Change « Beer Activist. (This originally appeared as my column in the Summer 2008 issue of American Brewer.) Cash-conscious customers are well aware of rising beer prices. But carbon-conscious consumers realize this is linked to the world’s expanding appetite for energy. Given the industrial economy’s heavy reliance on fossil fuel energy, it follows that brewing costs are escalating as oil hits record highs of over $110 per barrel.
Advanced environmental brewers such as New Belgium Brewing (NBB) are connecting the dots by reducing energy consumption and limiting release of climate-changing greenhouse gases (GHGs). But the climate challenge is a tricky one with impacts lurking in unexpected places. The Costs of Climate Change Effects from global warming are adding new dimensions to the energy equation. The carbon impact of a six pack of Fat Tire beer. A 2007 White House Executive Order requires federal fleets to rely on non-petroleum-based fuels for at least 10% of overall fuel consumption. Like this: New twist on green beer. Organic beer is old news. The latest attempts by breweries to go green have nothing to do with organic hops or locally grown barley. In fact, most of their environmental efforts have nothing to do with what goes into their beer at all. Instead, breweries are focusing their attention on greening all aspects of the beer-making, from the breweries to the packaging materials.
"More and more breweries are conscious about their [carbon] footprints and their impact on the environment," says Julia Herz, spokeswoman for the Brewers Association. "It's more than just a trend; it's a movement. " The movement seems to be taking hold. According to the Brewers Association, there are 1,500 craft breweries in the United States (defined as breweries that produce fewer than 2 million barrels of beer per year) and a growing number of them are embracing alternative energy, starting composting programs, recycling spent grain and using reclaimed materials, including brewing equipment, in their operations.
