The panels use silicon cells, which unlike other types, are less expensive but also prone to inefficiency caused by overheating. However,this is not a problem as the water on which they’re floating acts as a cooling system. 

Users have the option to add or remove panels in order to tailor the power output to their requirements. A single modular panel is capable of generating around 200 kW of clean energy.

This kind of system will not be installed in ecologically-sensitive areas or in open seas, but rather on reservoirs already in use for agriculture and industrial purposes. The water will not become stagnant because the panels are designed to allow oxygen to permeate through. So far, the companies have released a prototype that has been presented at the 4th International Eilat-Eilot Renewable Energy Conference in Israel. The designers have great plans for the future. They’re planning to install AQUASUN for a nine-month test period on a basin at a hydro-electric facility in southeastern France by the end of September.

Washers, dryers and dry cleaning make doing laundry easy, but they can be tough on the environment. With a few simple changes, you can reduce your environmental impact and trim your utility bills.

If laundry day doesn’t seem like a big deal, consider this: On average, an American household washes almost 400 loads of laundry a year, according to Energy Star.

Your laundry days add up, so it’s worth thinking about how you can minimize your household’s impact.

The less energy and water you use when washing your clothes, the better. Use your washer’s energy-saver setting if available. Washing your clothes with cold water will both slash energy costs (as you no longer have to pay to get the water hot!) and keep your clothes brighter longer – a double bargain for the earth and for your pocketbook. Also, cleaning your lint tray will keep your dryer working efficiently.

When it comes to loading your laundry machines, make sure you’re working with full loads. Filling your washer and dryer with clothes will help laundry day fly by faster and reduce energy use at the same time.

Consider not using your clothes dryer and use a clothesline instead. There are many different types of lines available designed to suit every type of home - either indoors or outside.

Butanol can be made greener by the research of a Japanese institute, who developed an energy-saving biobutanol with a density of at least 80 percent. They derived their biobutanol from a 1 percent concentrated butanol and used a zeolitic separation membrane.

Being derived from biomass sources, biobutanol’s overall carbon emissions are zero, since the carbon dioxide it emits when burned is reabsorbed by the next biofuel crops. Unlike ethanol, which has a relatively smaller energy density (27 MJ/kg), biobutanol has 34 MJ/kg and has the same cost per calorific value. Moreover, biobutanol is easier to store and the tanks don’t have to have special designs. It doesn’t mix with water, like ethanol, which is a plus.
