Current e-vehicles use lithium ion batteries. Solid state batteries with higher energy density do exist but they are too expensive for an average car. Toyota however seems to be in a position to produce affordable solid state batteries by 2022. Apart from higher energy density per unit of weight and extra advantage is that these batteries can be charged in minutes.

Youtube text: Mitsubishi Heavy Industries worked with Artemis Intelligent Power to build this prototype 7MW offshore wind-turbine which is now on test at Hunterston in Scotland. The video shows the rotor blades being made and the building and testing of the wind turbine’s Digital Displacement® hydraulic transmission at Yokohama.
Youtube text: Construction of the largest wind turbine in diameter in the world at 167m. The sea angel was designed by Mitsubishi Heavy Industries. Construction was in December 2014. Working with SSE, MHI Vestas, Artemis Intelligent Power, Innovate UK, and Department for Business Innovation and Skills to complete.
The Sea Angel Turbine is 7MW output and located within 1 mile of Hunterston Nuclear Power Station in Renfrewshire, West Scotland.

P.S. in this design the generator is still located in the nacelle.
Some people believe that methane hydrates, located at the bottom of the sea, could be part of a future energy solution. Recently a Japanese firm reported that it had produced non-commercial quantities of methane from methane hydrates, present ca. 300m below the sea bed at 1000m depth near the Japanese coast.
A Japanese macaque swims in a geothermal hot spring in the mountains of Japan. ow ironic that Stefan Larus Stefansson, Ambassador of Iceland to Japan, needs to tell the Japanese how big their potential for geothermal energy actually is, using his own country as an illustration. Interesting detail: most of the geothermal turbines operational in Iceland were made in Japan. 66% of the energy in Iceland comes from geothermal sources. Japan in contrast, despite having the world’s third-largest potential for geothermal energy, built its last geothermal energy plant in 1999, and all research funding from the government ceased in 2003, when the japanese government decided to put most of its cards on nuclear energy. Effectively Japan could replace 25 nuclear power stations with geothermal energy. 92 percent of houses in Iceland are heated by geothermal hot water, and heating prices are the lowest in Northern Europe.
Since the Fukushima desaster Japan is looking for alternative ways of generating energy for its economy. Geothermal energy definately is a candidate. Japan has the third largest reserves after Indonesia and the US. Currently Japan generates 535MW of geothermal energy, the eighth producer in the world. That’s 0.2% of Japan’s total output.
In the wake of the Fukushima desaster Japan has announced ambitious plans to boost solar power generation. What is special here is that there are no large-scale sar projects planned, but rather that the government will set the price of electricy. Industry Minister Yukio Edano may set a premium price for solar electricity that’s about triple what industrial users now pay for conventional power, a ministry official said. Read more…
Welcome to the new reality of energy scarcity. If a highly advanced country like Japan asks its citizens to voluntarily cut energy use, one can be assured that something big is in the making. In western Japan energy consumers will be asked to reduce demand by at least 15% compared with peak levels in the summer of 2010 for the period from July 2 through Sept. 7. The power cuts are linked to the nuclear power stations that were taken off the grid after the desaster in Fukushima. There is no reason not to assume that this will be a recurring pattern in the years to come, until the moment arrives where electricity will be rationed.
Kunstler in his yesterday column writes: “all of which points to the likelihood that Japan will become the first advanced industrial nation to bid sayonara to modernity and return to a neo-medieval socio-economic model of daily life.” Kunstler has earlier acknowledged that the days of globalism are over in the long run in the light of resource depletion, first and foremost oil. It is ironic that it had been the US that in 1854 under commodore Matthew Perry had forced Japan to open up for world trade. Before that Japan always had been a closed, read nationalist society, that did not need combustion engines to keep it’s society going. The only contact Japan had with the West up until 1854 was with the Dutch on the small island of Desima.
