Technology gets old – it’s just the way it works (or stops working). So what do you do with it when it’s time for a new laptop or cell phone? Unless you’ve got one of the new biodegradable cell phones, you probably don’t want to chuck all that plastic and silicon into a landfill where it will probably sit for the next few thousand years. So what are your options for recycling your technology? (more…)
Africa, typically a dumping ground for electronic waste from other nations, could produce more e-waste than the European Union by 2017, experts say.
On Energy.gov, we’ve been showcasing a series of stories about innovations from our National Laboratories that have been successfully commercialized – and how they impact Americans’ lives. During 2010 alone, our National Laboratories engaged in more than 13,500 technology transfer transactions – from (more…)
Although China may be a recent arrival in the “Big Power Club,” it is a very old, and wise culture. They have developed their nation to this point on the profound understanding that the average voter in the western world is basically a moron whose main life interest is in next week’s pay-packet. Why should you let this (more…)
Tony Seba is currently a lecturer in clean energy, entrepreneurship, finance and technology strategy at Stanford University. He is also an internationally known keynote speaker on the future of energy, entrepreneurship, innovation, and cleantech and high-tech market opportunities.
I recently sat down with Tony Seba to discuss his latest book, “Solar Trillions,” which is about market and investment opportunities in the emerging clean-energy economy.
CleanTechies: What is the premise of your book?
Seba: The clean energy economy will provide the largest wealth-building opportunities in history. The world will spend $382 trillion in energy over the next 40 years and every aspect of this industry is up for grabs: from generation and transportation to storage and use. The race for dominance has already started and the entrepreneurs, investors, and countries who win will dominate the 21st century. The problem is that the whole conversation about energy is wrong.

Emefcy, a microbial fuel cell startup based in Caesarea, Israel, has raised $5 million at a company value of more than $10 million, post-money.
Emefcy, co-founded by serial entrepreneurs Eytan Levy and Ronen Shechter, is developing the MEGAWATTER™ technology. This technology produces low cost electricity (at $0.10/kWhr) and hydrogen in a bio-electro-chemical process from wastewater treatment by leveraging Microbial Fuel Cell (MFC) technology.
Our high-tech products increasingly make use of rare metals, and mining those resources can have devastating environmental consequences. But if we block projects like the proposed Pebble Mine in Alaska, are we simply forcing mining activity to other parts of the world where protections may be far weaker?
Every time someone pushes the on-button on an electronic device, there is an expectation that the unit will power up quickly and display images in vibrant color. There is the further expectation, especially when using electronic devices for communications such as email access, web downloading, and texting that the response time will be immediate. We live in an age of technological arms races in which manufacturers gain market edge by creating products that are faster, have more applications, have a broader network reach, and generally do more.
The processing capacity of digital electronic devices doubles about every two years (Moore’s Law), and this capacity increase is enabled by an expanded use of elements. For example, computer chips made use of 11 major elements in the 1980s but now use about 60 (two-thirds of the periodic table!). And the electronics sector isn’t alone. Engine turbine blades for aircraft are made of alloys of a dozen or so metals; motors and batteries of green-technology hybrid vehicles depend on several of the rare earths; advances in medical imaging have come about by the unique band gaps of elements such as gadolinium. It seems that there are no limits to what the imagination can create except for the fact that many of the metals are globally rare and, given the nature of current technology, non-substitutable.

In the last 15 months, President Obama and his Administration have made significant progress in changing the way America thinks about energy and the environment, making the vision of a 21st century clean energy economy a reality. From historic investments in clean energy infrastructure and technology; improved efficiency for buildings, appliances and automobiles; more diverse energy production from domestic and renewable sources; and reduced emissions that contribute to climate change – the President’s comprehensive strategy has put Americans back in control of their energy future, created new jobs and laid the foundation for long-term economic security, and led by example in exercising good stewardship of our environment.
