New Breakthrough Suggests Hydrogen Fuel Might Be The Future

The sun has known to be a source of energy, but can also be used to drive reactions that help create greater amounts of energy.

Scientists have now combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.

Although solar energy is still a midget among U.S. energy sources, its rapid growth from a small base is beginning to make some of the big players nervous. Regulated utilities in a number of states—Arizona, California, Colorado, Idaho and Louisiana—have started to complain about the various benefits for photovoltaics (PV), says Mac Gunther, in a article appearing on Yale's environment360 website.

Interesting enough, in Portugal the "Micro produção" allows anyone to generate renewable  energy and feed in to the grid and the price of the energy generated at home is more than twice the price of the energy we pay from the grid operators. There is a defined process for this. See http://www.edpsu.pt/pt/PRE/Microproducao/Pages/ligacaoRede.aspx
In many cases, the grid users with local micro solar production in the end of the month receive from the operator money in the end of the month. Usually everyone sells all energy locally produced and buys from the operator the energy they need. It is a good business specially in summer months.

Sophisticated cybernetic implants have been a science fiction staple for some time now. Assume cybernetic implants were affordable and painless, would you get an implant that enhanced your vision or hearing?

This does not bode well for the energy utilities. When a bank as influential and capable as Deutsche Bank says "three-quarters of the world’s market will be “sustainable” for solar within 18 months, meaning they can operate with little or no subsidy"  it should have the energy utilities shaking in their boots.
