What’s interesting is the organic technology developed to support this program. This project will use horsepower submersible pumps powered by solar panels. The water will be installed on existing high-yielding bore wells and pumped during the day into 5,000 liter storage tanks.

It is not surprising solar based water pump systems are being developed in India. There is a market with an ever growing demand. Only 35 percent of rual households in India have piped water. The goal is the dramatically increase this by 2022, which will not happen without the power to pump, purify, and pipe the water. India’ Rs +500 crore “investment”  will provide larger scale validation of the reliability and  maintainability of solar based water pumps systems.

India’s investment into this sort of technology is not new. As see summarized in Solar Water Purification in India, focused research and investment has been producing results. What is of great surprise is the apparent vibrant Indian solar water pump market. Just check a few of these links – all Indian – all focused on the needs of the Indian market:

• (and many more – just search for “solar water pumps India”)

Looking through some of the solutions demonstrates intimate knowledge of the market and environment for which these systems are installed. It also indicates there is a local support foundation to repair the systems once installed.

The advise for anyone looking to “help India” with clean water needs to consult with these companies who focus on this “market.” Their market insight would prove invaluable to finding new ways to meet’s India’s 2022 goal – 90% of rural household with running tap water.

Beta TidGen Power System Project)

ORPC is one of many “tidal power evaluations” which are not moving to production phases. Hyundai Heavy Industries has deployed a 500 kW tidal current power system at Uldolmok Passage in Jeollanam-do, southwest Korea using the Gorlov turbine based system (similar to the ORPC system) (2). Production test phases are a core engineering milestone. It take many of the assumptions for how the mechanic and electrical systems will operation and put them under long term production stress.  These lessons will be used for later production phases, continuously improving the systems.

Bottom line, tidal power will be a reality. We moving from the “hope and hype” to “engineering and experience.” With engineering and experience, we will then have the data to validate the long term economic viability of tidal power (i.e. does it make economic sense).

(1) Building good will in the community is a nice lesson learned. Some of these projects will have changes to the water line and add an “industrial” view. The open house helps.

(2) Gorlov’s turbine, inspired by the Darrieus rotor of 1931, extracts up to 35% of the kinetic energy of moving water, even with a flow rate of as little as 1.5 metres per second and in only a metre of water. Compare that with the energy yield of only a little over 20% achieved by the most efficient models to date. The Gorlov Helical Turbine is also independent of dams – it can be sited in any suitable underwater location.

ENERGIZE YOUR DAY; POWER THEIR FUTURE!!!!

For once, guiltlessly drink caffeine for a day! Both Stanford Coupa Locations, ALL DAY! Simply order a Latte or Cappuccino this Wednesday! Globally 1.6 Billion people lack access to electricity and 2.4 billion people spend 6-9 hours gathering fuel such as wood for cooking.  Lack of modern forms of energy keep people from escaping poverty.

Bright Green Energy provides the technology, training, and initial funds to support local female entrepreneurs to start their own eco-ventures. These women then become solar technicians, solar accessory manufacturers, as well as sales and marketing agents into their customer base.

Heads up! Fundraiser on Univ. Ave location will be June 10th!

• $5m Port Kembla wave generator wrecked
• Port Kembla wave generator lies on sea floor
• Huge swell sinks wave energy generator
• Barge’swatery grave (UPDATE!)

While this is a setback, it is part of our engineering journey – learning how to build for environments whose force of nature is hard to predict. Engineering experience is our best guide. We’ve seen this in clean tech projects through out the last decade. Where engineering hubris was slammed in the team’s face as they watch their project eviscerated by the forces of nature. Oceanlinx “had more than double the required mooring lines in place to ensure its safe operation.” But, as we now know, what we refer to as “requirements” changes in the face of experience.

Is this an “energy dream sunk?” No. It is an engineering experience we need to live through, learn from, and then move forward. Oceanlinx’s concept for power generation is enticing. The prototypes are proving the technology (check the videos listed here: Oceanlinx’s media gallery).  Oceanic engineering is hard. How hard? use this PG&E RFI Summary on the responses to their Wave Energy Converters (WECs). Start checking out the companies (peers to Oceanlinx). What is interesting is that few to none are at the stage of Oceanlinx. Hopefully, we’ll see a Mk3PC-2 built and deployed …. soon.

Artificial islands are not new. In fact, we know how to build industrial strength islands which can withstand the onslaught of the oceans and mother nature. We done this from factories i Alaska, to airports in Asia, to facilities in the Gulf of Mexico, to the residence off Dubai. The principle is sound, it is now a factor to see if the economics work.
