I think they should have new building codes that require solar panels, geothermal heating pumps, rainwater collecting cisterns, passive ventilation, thermal super glass, and caulking. If they mandated green switches that shut the power to all appliances but the refrigerator, that would be fine with me. I believe they should even have, broadleaved trees on the south side, to provide shade during the summer. Perhaps they could have eaves to provide extra shading. I believe all commercial and industrial buildings should require wind turbines and skylights on the rooftops. Moreover, I believe all flat-roofed buildings should have green rooftops. Indoor plumbing is included in all building codes. You can no longer have an outhouse outside. If all buildings must have bathrooms and fire exits, why shouldn’t they include these in new codes? If they shall abide by OSHA standards why not make them abide by EPA standards. Plus, they can require other buildings to be retrofitted through time. Imagine how picturesque Wal-Mart and other big box retail chains would look with green rooftops. Picture how much energy they could return to the grid. Any thoughts on this?

I want to one day build the world’s first green theme park. I aspire to make all the rides generate electricity from the centrifugal force. For example, the ferris wheel, whirling dervish, looping starships, revolving gates, merry-go-round, carousel, tilt-o-whirls, and bumper cars could produce energy. I even want a gym with treadmills and stationary bikes that could do the same. Not to mention cranks that restless children can turn. I imagine the water rides could have stream engines that produce electricity as well. The blenders from all the smoothie bars could help, and the waste vegetable oil from the restaurants can fuel the rides. Needless to say, all the building rooftops could have solar panels and helical wind turbines. I even want the restrooms to generate electricity with methane digester toilets. Therefore, anytime someone takes a crap, they’ll be providing power to the theme park. Solar water heating, eaves, daylighting, ice coolers, passive ventilation, and rainwater collection would be everywhere. No green theme park can come without a green space. This idea encompasses a large biodome with several exotic species. Essentially, I want the entire output of this place to be equivalent to that of a power plant. Then several other theme parks can adopt this principle. Would you take your kids to a place like this? Last but not least, I have to decide which of the three cities I would build it in. It would have to be either New York, Chicago, or Los Angeles. Which is the most sensible locale
Hey You: Widespread use of ethanol sounds like a sexy idea, but in reality it’s impractical. It can’t replace gasoline as a dense energy source. It actually takes more energy to make ethanol than you get out of it. Further, that would cause the prices of corn to spike along with dairy and wheat products. Alas, ethanol is a corrosive material. Therefore, it can’t be transported through pipelines. The kind they use to replace diesel is actually E-85 which is 85 percent gasoline and 15 percent ethanol.

Therefore, it would have to be either New York, Chicago, or Los Angeles. Which is the most sensible location?

I think the government should force a mandate that all building codes include these. I think new buildings should include them and current buildings should be retrofitted with them.

solar panels
geothermal heating pumps
passive ventilation
wind turbines
methane digester toilets
rainwater collecting cisterns
compact florescent bulbs

If all homes have to have bathrooms, I see nothing wrong with this. If you can no longer have an outhouse in your backyard, I’m keen with this. Buildings now have to have emergency exits, fire extinguishers, and sprinkler systems. Therefore, I see nothing wrong with incorporating these into building codes. What do you think?

I have been working with the current owner of a small company over the last few months with intentions on purchasing it on Jan 1, 2009.

The business distributes, direct sells and installs wood furnaces, solar panels, wind turbines, passive solar and radiant floor heating, with two new products slated for introduction next year. Dealer network of 6 active, 6 non-active, with open potential to develop dealers throughout the west.

At first, the owner wanted to be involved for 5 years and finance half of it, Now he wants all cash up front and only wants to be involved for 6 months.

Last years sales were 0,000 with net profit in the 0,000 range.
Next year he is estimating sales of 0,000 due to the economy and the depressed price of oil and energy. Gross profits will be in the ,000 range.
The company does not have auditable financials, he does not have to sell the business.

Sales price is 0,000 with 0,000 in good will, 0,000 in marketable inventory and ,000 in assets.

Financing would be 0,000 @ 8% over 7 years, first two years interest only payments required, with ,000 extra cash as working capitol.

New owner has business management experience, strong interest in entering the alternative energy market and a small network of entrepreneurs for advice.

So the question is:
With energy prices, the economy depressed and credit hard to come by, would purchasing this business (on credit) be a good investment?

Thanks for the answer Getalife.

After additional analysis and advice, an offer would be 5,000, max bid at 0,000.
