Fighting the Military on Energy Strategy

For several years, the U.S. military has been one of the most active proponents and early-adopters of renewable energy and alternative fuels, with their Operational Energy Strategy.  Why?  Several reasons: 1.  Fuel delivered to the remote front-lines such as in Afghanistan for use in power generation and transportation has an “all-in” cost of $400/gallon.  Any energy source […]

Book Review: Private Empire

After having extensively tackled the topic of al-Qaida with The Bin Ladens and Ghost Wars, Steve Coll has turned his attention to ExxonMobil (NYSE: XOM).  At first blush, this might seem like a dramatic thematic departure for Coll as a journalist and author.  However, Coll’s newest work, Private Empire:  ExxonMobil and American Power, makes clear that […]

Cleantech, Hedging Economics, and Commodity Hell

It never ceases to fascinate me the massive amount of impact commodity price swings have on business plans.  Apple, Google, Facebook, they don’t deal with this.   Commodity price swings just don’t hit their bottom line.  But in cleantech, well, government and policy is king, commodity and resource shocks are queen, you and I are […]

Corn Flakiness

The historic drought this summer across most of the United States has severely damaged this year’s corn crop.  According to the U.S. Department of Agriculture, corn production is expected to be down more than 10% from last year. Not surprisingly, corn prices have surged.  What may be surprising is how much they’ve surged:  up to record levels exceeding $8.00/bushel, […]

Two Years Later: Revisiting the Taxonomy of Cleantech

It’s been two years since Kachan & Co. first published its definition of what industries and categories constitute cleantech. A lot happens in two years, so it’s time to refresh our taxonomy. A clean technology taxonomy, a list of nested categories, is important. It shows where a clean technology “fits.” It helps vendors understand their competitive […]

The End of Nuclear Power? Or Just the Beginning?

This week’s news: US NRC freezes decisions on new reactor, license renewal applications “The US Nuclear Regulatory Commission voted unanimously Tuesday not to issue final decisions on granting licenses to build new nuclear power reactors and 20-year license renewals to existing ones, pending resolution of the agency’s waste confidence rule overturned by a court in June. […]

Clear Signs of Innovation in Glass

Glass has been made for thousands of years, and innovators have always been tinkering to improve the basic product.  Over the years, these improvements have mainly been in terms of color, strength, weight, quality.  The cleantech imperative of the past few decades is now pushing glass innovations on two more dimensions, energy efficiency and power […]

Seducing the Coulomb Barrier

by David Niebauer “In contrast to conventional experience based on using high energy to overcome the Coulomb barrier by brute force, the CANR [Chemically Assisted Nuclear Reaction] environment apparently uses a mechanism that can neutralize the barrier. This more subtle method apparently is obscured when high energy is applied, this situation being like the difference […]

Top 10 Cleantech Subsidies and Policies (and the Biggest Losers) – Ranked By Impact

We all know energy is global, and as much policy driven as technology driven. We have a quote, in energy, there are no disruptive technologies, just disruptive policies and economic shocks that make some technologies look disruptive after the fact.  In reality, there is disruptive technology in energy, it just takes a long long time. […]

Scavenging For “Free” Energy Isn’t Necessarily Cheap

5 watt-seconds.  That’s the miniscule amount of energy released mid-stride upon the ground when the average person is walking.  At least, so it was reported in a business plan I recently read from a college student group to pursue a new technology concept to harvest the otherwise-wasted energy created by foot traffic in dense pedestrian areas such as airports. […]

Bettering Batteries

I recently got an email entitled “Trojan Tips”.  Hmmmm, wonder what that could be about?  Alas, upon scrolling down from the subject line, I found the message provided advice from the battery manufacturer Trojan about proper battery management practices. The more you get into cleantech, the more you realize how central a role is played by […]

Thoughts from Intersolar 2012

By Guest Blogger Charles Waitman I spent a day at Intersolar North America in San Francisco, considered by some to be North America’s premier exhibition and conference for the solar industry.  My career, to date has been in the oil industry.  This was my second Intersolar conference.  These are my observations. PV dominated the conference. […]

Hot Enough For You?

So far, the summer of 2012 has been a scorcher for most of the U.S., following hot on the heels of a much warmer than usual winter.  Last week, as reported by the Washington Post, the National Climatic Data Center released its State of the Climate report for June, in which NCDC noted that not only were the last […]

7 Cent Solar Power for my House

by Neal Dikeman The other night I answered an ad on Craigslist.  Not surprising, since  buying and selling things on craigslist is kind of my hobby.  But this one was for solar panels.  180 Wp panels from a wholesaler.  Offering for $190 ea if I bought one, or $180 if I bought 20 or more, […]

David Anthony’s Last Question – Can We Power the US Solely off of Solar?

By Tao Zheng, with David Anthony, an active cleantech venture capitalist, who passed away in April 2012.  The sun is the champion of all energy sources, in terms of capacity and environmental impact. The sun provides earth with 120,000 terawatt (TW) energy, compared to technical potential energy capacity of single digit TWs from other renewable sources, […]

La législation sur les jeux d’argent en ligne présente souvent des lacunes qui résultent du développement rapide de la technologie qui sous-tend l’évolution du secteur. Certains pays, dont la Belgique, le Canada, la Finlande et la Suède, ont des monopoles d’État sur les jeux de hasard et n’accordent pas de licences aux exploitants de casinos étrangers. Selon leur législation, les opérateurs titulaires d’une licence sur le territoire de ces pays ne peuvent être considérés que comme légaux. Dans le même temps, ils ne peuvent pas poursuivre les opérateurs de Comment obtenir un bonus de casino en live?
