California Clean Tech Open 2007 Winners Announced

Six clean tech startups each awarded $100,000 in prizes

Case Study - Geothermal Energy System

Although they invested a little more capital in the installed system, the annual energy cost savings will finance the extra capital and the system will pay itself back in the next 6-8 years. In addition, they have become one of the most environmentally responsible owners in the area with an annual emissions offset equal to planting an acre of trees.

EarthToys Interview - Sun Run Electricity Package

Sun Run owns and maintains the panels, not the homeowner, eliminating the hefty upfront cost and maintenance woes. Once the system is installed, Sun Run provides monitoring, all required maintenance at no additional cost and guaranteed system performance - or your money back.

EarthToys Interview - The Community Solar Program

We have seen the solar programs serve as a source of community pride for residents and a bonding agent between neighbors. When you make a big decision like going solar as a group, it also tends to remind residents of the larger impact of their decision on the environment and the fight against global warming.

Editorial Comments

I must thank the celebrities who have brought our cause to the attention of the world. Now let's hope the momentum carries through and we actually start to see real solutions and progress taking place. We need 2008 to be the year of implementation. Time for the engineers to be set free to do what they do best ... build stuff :-)

Electric Vehicle Conversion

Large numbers of people are discovering that, with some effort and a little money, a clean, reliable beast of transportation can emerge from ones own garage. Generally referred to as EVs (electric vehicles), these self-made conversions offer low cost of operation and low cost of ownership - a winning combination.

Energy Saving Tips in the Kitchen

EEI has compiled the following top 10 cooking tips for making sure that the electric bill this holiday season looks as good as the roast.

Hydrogen Contest Returns after Two-year Hiatus

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.

SUV Drivers vs You

SUV drivers pollute the planet with their gas-guzzling snobbism. Or do they?

The Nature of Grid Tied PV

Grid-tied PV systems without energy storage do not reduce load in a substantial and predictable way, which will be a keystone of sustainable energy policy. We will need to institute three main objectives to reduce greenhouse gasses and localize power production to facilitate smaller, efficient local power plants.

The Santa Monica Alternative Energy and Transport Expo

By far the most popular items among the technology-dazzled laymen were the hydrogen fuel-cell vehicles. Among the cars on display were a number of first-generation Honda FCX hatchbacks, which had attracted a crowd clamoring for rides.

The Well-Planned Disaster

"What gets us into trouble is not what we don't know, it's what we know for sure that just ain't so." -- Mark Twain

Tire Derived Fuel

With the fossil fuel prices increasing rapidly, the waste from scrap tires will certainly be increasingly be made use of. Developing innovative and economical as well as effective systems for TDF usage is and will always be a challenge to the business.

Using Sound Energy to Drive Your Car

Until now, acoustic or sound energy has not been used effectively to impose thrust or force on an object for purposes of providing useful work.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
