We've come up with a patent-pending design improving the basic concept of the Solar Updraft Tower. There are 6 patents pending on the improvements to this old technology, the first being on a method to reduce the tower height by over 80% and the amount of land needed by 90% so that we are able to deliver 120MW of electricity at a rate of 4-6 cents per kWh. Other patents increase airflow, efficiency, and output.

There are many companies still trying to use the old technology, just recently a tower was completed in China which was over 2000 feet tall and produces only 20MW. It cost nearly $850MM.

We're heading in the opposite direction.

Our design has taken these tall towers and reduced the height down to 450 feet. The total footprint needed is 640 acres. We have very few moving parts and only requires yearly maintenance with two operators.

A byproduct of our electrical production in fresh drinking water. An internal desalinization plant will produce clean drinking water which can be bottled or pumped into local water supplies.

We can produce utility-scale electrical output that's inexpensive and scalable to meet our future mandated energy demands.

"I have a vision of a future where our energy is not only renewable, but abundant and excessive so we can enjoy the fruits of our labor while maintaining our responsibility to the environment. I believe Solar Thermal Tunnels can provide that future."

  California's RPS now at 33%

California (through it's Renewable Portfolio Standard, or RPS) has become the first state to require it's utilities to increase their renewable energy generation from 20% to 33% by 2020. The new law will be implemented in 3 steps: 20% by 2013, 25% by 2016, and 33% by 2020.

In order to do this, the California renewable energy sector must quadruple in size in the next few years. While there are few small renewable energy companies in California, there are none that produce a utility-scale output thats comparable to a modern gas or coal power plant.
