An energy company in Israel plans to launch a solar farm this month using new technology it says can produce cheap and efficient electricity while supplying hot water to homes.

As with all solar energy systems, investors and consumers may be turned off by high initial costs and the need for strong sunlight. But if the commercial pilot works, Israeli start-up ZenithSolar plans to make small units for homes in two years.

Colin Bennett on 26 Jan 09

Penn State University scientists and the Virginia Commonwealth University have found something that is the ultimate dream and hope of alternative energy researchers: use water as a fuel. Their findings show that water can be split into its two constituents, hydrogen and oxygen, at room temperature and without any external energy addition. For that matter, they expose water to selected nano-engineered clusters of aluminum, acting as catalysts. What's shocking and interesting is the new approach, detaching from the centuries-old premise that water can only be split by electrolysis, using a high amount of energy.

One of the most common questions in the realm of water security is, what are the main barriers to dramatically expanding desalination? It seems to offer an essentially unlimited supply of water, and it's practiced on a large scale in other parts of the world, so why not here?

Solar Water Heaters Now Mandatory In Hawaii | MetaEfficient - 0 views

shared by Hans De Keulenaer on 30 Jun 08 - Snapshot

Hawaii has become the first state to require solar water heaters in new homes. The bill was signed into law by Governor Linda Lingle, a Republican. It requires the energy-saving systems in homes starting in 2010. It prohibits issuing building permits for single-family homes that do not have solar water heaters. Hawaii relies on imported fossil fuels more than any other state, with about 90 percent of its energy sources coming from foreign countries, according to state data.

Oh, it can be done. There are no scientific laws that say you can't run a car on water. In fact, a Japanese company is the latest to claim they have pulled it off. See the video here:

However, what you can't do is run a car on water without energy inputs greater than you get from splitting the water.

Remember when you were a kid and your
parents made a big fuss about turning off the light when
you left a room? Who knew that, besides adding to the
monthly electric bill, keeping a single 60-watt
lightbulb lit for 12 hours uses as much as 60 liters of
water? According to researchers at the Virginia Water
Resources Research Center, in Blacksburg, Va.,
fossil-fuel-fired thermoelectric power plants consume
more than 500 billion L of fresh water per day in the
United States alone.

6,000 Gallons of Water to Light a LightBulb?! | EcoGeek - 0 views

Colin Bennett on 18 Apr 08

A recent study was published yesterday by researchers at the Virginia Polytechnic Institute quantifying a bunch of different factors in water use in the energy industry. Some of the figures are staggering. Using America's current power mix, it takes up to 6,000 gallons of fresh water to keep a 60 watt light bulb lit for 12 hours a day for a year. Most of this energy is consumed as a cooling fluid at power plants.
