The experimental project is funded by the government and led by Marubeni Corp. It requires approval from local fishermen before becoming a commercial operation. The 2-megawatt turbine from Hitachi Ltd. was nicknamed “Fukushima Mirai,” the Bloomberg report said, adding a floating substation has also been set up and bears the name “Fukushima Kizuna.” Mirai means future, while kizuna translates as ties.
Two more turbines by Mitsubishi Heavy Industries Ltd., with 7 MW of capacity each, are expected to also be installed. Bloomberg noted the Ministry of Economy, Trade and Industry has said the floating offshore capacity may be expanded to 1,000 MW.
Given location has been secured and transmission lines are in place, it seems quite feasible to place an Energy Island in the vicinity of a floating wind turbine(s) to add energy storage (CAES) plus means to tap tidal, wave, and solar sources of energy. That addition would offer means to provide a much more abundant and reliable supply.
Capturing energy from ocean currents project wins EPA grant. (Nanowerk News) A University of California, Riverside student recently learned he will receive a $15,000 grant from an EPA national sustainable design competition for his idea to capture energy from ocean currents. Raul Delga Delgadillo, who will be a senior this fall at the Bourns College of Engineering, plans to spend the upcoming school year building a small-scale turbine and buoy system and testing it in a flow tank to determine the best way to maximize energy extraction. He expects the system will provide as much energy as an average wind turbine.
Planet Earth is experiencing rapid change in its atmospheric composition. Carbon dioxide concentration has spiked above 400 parts per million and is inexorably headed higher as humans burn increasing amounts of fossil fuels. A vast majority of scientists attribute a rapid spike in global temperature to a greenhouse effect caused by carbon dioxide and other greenhouse gases that are produced from burning fossil fuels. The inevitable result of continuing and increasing use of fossil fuels is that the planet will become much less livable for human beings and countless other species of life:
Island nations are disappearing under rising oceans.
Species are becoming extinct at a rate never before seen during human history.
Wild fires are becoming larger, and catastrophic storms are becoming more frequent and more energetic.
Crops are failing because of drought and extremely high temperatures.
Almost every aspect of human culture is being affected or will be affected.
See here information about developments in power production that are important because they have promise to help stop global warming. Too often, we focus of developments that are incremental and are constrained by scientific or academic discipline. Needed are breakthrough attempts to find solutions to global warming that are large and ambitious enough to actually give hope that global warming can be stopped. Incremental advances are important, but they are now coming too slowly to meet the challenge of rapidly deteriorating environmental conditions. We need to think bigger.
Below is an artist’s conceptual illustration of “Energy Island,” an example of the kind of innovative approach to energy development that is highlighted at this site. Energy Island is an invention that integrates both well-known and new technologies to supply abundant electricity from non-fossil-fuel sources that are safe, clean, and renewable.

Energy Island – generates abundant and reliable electricity from an ocean-based platform. Multiple well-known and new technologies are co-located and integrated to tap energy from wind, water, and sun. A unique storage capacity allows Energy Island to deliver electricity when it is most needed.
New Hoover Dam – Energy Island, West of Los Angeles. Electricity generation capacity from a drought-stricken Hoover Dam can be replaced by tapping ocean energy.
Proposed Effort to Slow Melting of Glacier in Antarctica – Energy Island in Antarctic waters can use simple, known technologies to slow melting of glaciers by cooling water that is melting them on the bottom and by fostering new snow fall to protect glacier surfaces on top. Melting of top surfaces is quicker when snow and ice become dirty and less able to reflect sunlight.
Google is a leader in determining how the U.S. will satisfy its energy needs in the future. Google has invested in a wind farm in Texas and a solar plant in California. Other investments have shown support for highly innovative developments: flying wind turbines and a network of transmission lines to service wind farms to be built in waters off the Atlantic coast. Google Energy has independently developed assets for generating electricity that exceed the supply that is delivered by Hoover Dam.
As a customer of utility companies, Google has shown an ability to influence utilities to develop generation of electricity from renewable energy sources like wind and solar. Recently, Grand River Dam Authority, a utility in Oklahoma, moved to invest in a 48-megawatt wind farm. The utility thus succeeded in keeping Google as a customer instead of seeing Google develop its own wind farm. Generally, Google has been effective in stimulating development of electricity from renewable resources because of its willingness to write large, long-term contracts for the purchase of green power from utilities.
Super-capacitors are already changing the future of energy. According to futurist Daniel Burrus, “When we look at renewable energy sources such as wind, solar, and waves, great strides have been taken, but until we find a way to store electricity for use at a later time, these will help but not be game changing. The good news here is that there is a technology that is already changing the game.” Super-capacitors can store energy to meet peak electricity demands and to smooth delivery of output from renewable sources. They are also being developed to improve energy efficiency in electricity applications — from autos to laptops.
“… the news came at a surprising time: Just two weeks ago, Entergy won a hard-fought U.S. Court of Appeals case. The court ruled that Vermont lawmakers, who’ve been worried by the plant’s poor safety history, lacked the authority to shutter it.”
America has far more than enough renewable energy resources to meet its entire electric demand.
World-class renewable resources from wind in the Great Plains to solar in the Southwest could power the whole country more than a dozen times over. The fuel for these power plants, wind and sunlight, are unlimited and will always be free. State renewable energy standards once considered ambitious at 10 to 40 percent now look modest in light of recent growth. Given our current understanding of renewable energy resources, technology, cost, and integration, it’s now realistic to envision a future where renewable resources provide far higher shares of America’s electric generation needs — 80 to 90 percent or more. The only remaining barriers to achieving such massive increases in renewable energy use are a lack of understanding and a lack of political will. We are overcoming the former as we discover the truth about renewable energy. It’s inexpensive, reliable, abundant, all-American — and yes, it’s still clean.
