The interesting thing is that despite the fact evacuated tubes have better performance throughout the day because of IAM, are more economical due to ease of installation, and are capable of reaching higher temperatures, the technology has not received the recognition it deserves since the majority of the publicity we currently see focuses on PV.
A new eco-friendly £5 million private care home in Sussex has elected to use solar energy as the primary source for both its heating and lighting. Eric Hawkins, MD and founder of Powertech Solar, describes how the project has provided an ideal opportunity to demonstrate the energy saving potential of the company's Suntech Solar Commercial range.
New technology in passenger cars makes biodiesel a much sought after fuel as small diesel motors are now better able to give their gasoline fueled counterparts a run for the money. Reports of 50 mpg results from biodiesel use are becoming commonplace, often in the VW TDI motor and similar models.
The National Renewable Energy Laboratory is creating a small wind turbine testing facility, and with the help from industry experts, is creating a testing standard for manufacturers so we can finally compare apples to apples.
Over 100 students from four countries comprise the thirteen teams that have submitted design abstracts this year. Design ideas include waste to hydrogen, back-up and emergency power supply, fuel cell and Hydrogen ICE vehicle implementation, just to name a few.
So now you have a very simple device to guide people in making good parabolic basins for making solar ovens! I believe this type of simple device will help a lot of people to improve their lives.
What strikes me most as a leap forward in terms of innovative, even disruptive, business concepts, is the installing of a waste-to-energy plant at the site of a power-customer itself.
The awareness of travel consumers is rising that our environment is worth considering. If the travel industry does not answer the call, voices will arise to discourage people to go to such idyllic places as the Caribbean.
The collector being enclosed or open faced would require surface care and significant weekly cleaning. Sopogy's panels would park at night, meaning the collector surfaces are protected so as not to be exposed.
In the Caribbean, the options are essentially the same, but practically wind and solar energy are the most promising short term solutions.
The research showed that these panels will work in northern climates. The system was operated over a one month period in February and March when temperatures were at times lower than -20º C.
This article does not pretend to be an exhaustive dissertation on solar ponds, but it should be enough to wet the appetite of anyone who is searching for a relatively simple almost passive way of collecting the sun's heat and energy.
Market and environmental factors are driving the improvement of PV systems technologies and a new residential project is proving their large-scale economic viability.
Bio-Lipid oil can also be used to produce one of the lowest cost and most environmentally friendly fuels known to man: bio-diesel. Bio-diesel made from bio-lipid oil, from micro-algae, burns cleaner, produces less CO2 (with no sulfur dioxide emissions) than petroleum based diesel fuels, and it's renewable and sustainable.
Passive solar design takes the pressure off conventional heating and cooling systems.

Professional weather sensors form the heart of large solar plants supporting their operation and performance. Lufft was the first manufacturer to combine several sensors in one housing, bringing the largest multiparameter weather sensor family with 19 members into being. Many of them are well-suited for solar site assessment and continuous monitoring. The most commonly used one is the WS600 delivering data on temperature, air pressure, wind, relative humidity and precipitation. Through its open protocol, it can easily be attached to radiation sensors e.g. from Kipp&Zonen. Other models have an integrated Silicon, Second Class or Secondary Standard radiation sensor.
