Question by Psssst! wanna send a letter?: What's the difference between a proper Solar water heating panels?
and household radiators painted black and housed in a cloche. Being a tight git I built my Solar water heating system for £180. It's three 1.2m x .6m panels, a pump and a controller. It gives me tons of hot water on a sunny day and does a bit even when it's not sunny. So whats the difference? Why do people spend £7000 on solar water heating systems?

Answer by BMS
first,

good job, it really isnt that difficult, but most people would rather pay than do the work...

second, from your picture, the water appears to be affecting you.....this may not be a good selling point.

good work!

Question by Fynnagin F: what colors should tubes be for a solar water heating system?
Solar energy can be used to heat water for a pool by running water through a series of pipes or tubes. What colour should the pipes be? What other features should this system have to improve its efficiency?

Answer by fill Yerboots
Matt black unless you are in a seasonally very sunny area. The black absorbs heat very well, so potentially it could get hot enough to boil the water if you are in an occasionally very hot climate. Some areas use pale colours because of this.
Black absorbs heat best, but also radiates it better than white or chrome surfaces.

If the US does more domestic oil drilling, the oil companies get richer. If the US develops alternative energy (wind, solar, etc), this would create a whole new industry and create more new jobs.

Best answer:

Answer by Zach Twhy don't we do both? drill for oil for short-term relief, while developing alternative energy for the long term.

the two aren't mutually hostile situations, they can work with each other.

Question by jay: The Sanchez household is about to install solar panels to reduce the cost of heating their house. ?
In order to know how much the solar panels help, they record their consumption of natural gas before the panels are installed. Gas consumption is higher in cold weather, so the relationship between outside temperature and gas consumption is important. Here are data for 12 consecutive months:
Degree days193300081127463834
Gas used3221.610.70.71.63.15.17.776.1

(Use decimal notation. Give your answer to three decimal places.)

Best answer:

Answer by Ape -X-
A graph of how much revenue oil barons and the refining process would lose in relation the % of renewable energy as a total of energy production would be the most pertinent in modern society.

Yes we think that you huge businesses should stop your hugely profitable exploits and instead spend billions investing in renewable energy. Afterall it's only money isn't the planets more important and I am sure you didn't become Oil barons because you are incredibly selfish and want far more than everyone else even if it means millions have to starve and die and suffer.

People wake up stop your governments from supporting these people renationalise your power industry invest in research and maximise renewable energy. Or sit back and let them charge you interest on the loans your govenment takes to buy weapons that you manufacture to send your own people to die for their profit and finacial security.
