Energy storage prices are dropping fast. If you follow me, you’ve seen me write about this before. Energy storage prices have in fact been dropping exponentially for at least 25 years. Here’s a new piece of analysis – a model that uses a 20% learning curve per doubling to that project Li-ion batteries dropping to 5 cents per kwh round-tripped through them by ~2030.

The carbon capture and storage project at the Boundary Dam in Saskatchewan is about to go live as reported in the press today. The project goal has been to eliminate 90% of the CO2 generated by the coal-fired power plant. Additions have cost $1.4 billion CDN, $115 million over budget, and represent what is believed to be the world's first commercial-scale CCS project to go live.

Surely gardens are a place to get back to nature, to escape from technology? Well, when journalists ask to see really advanced technology, I take them to the garden. Humans still have a long way to go to catch up with what nature does all the time.

For the past week or so there has been a lively ongoing argument in a LinkedIn Group about the chicken and the egg. Well it's not about chickens and eggs, it's about which global problem is real and which is not. One side argues that climate change and carbon emissions represent the most pressing problem the planet faces.

Gizmos & Gadgets: Rowbot Robot Tends to Farmers' Fields

Len Rosen's picture

No part of our highly technological economy today is free of being rethought by applying automation in the form of robots. In the past I have written about the use of field robots in agriculture. But these were largely university projects still in the laboratory. But now a new company in Minnesota is turning laboratory experiments into a commercial agricultural robot aimed at corn farmers. The company has created Rowbot, designed as a automated fertilizing machine for now but with plenty more applications to come.
