Cleaner Jet Engines

This is great news. Technology people like to point to clean tech solutions that are literally decades away from mass market because they are the more intellectually interesting problems to tackle. Environmental zealots think the government should just start banning anything that emits exhaust, throwing us back to the Neolithic period somewhere between the Copper [...]

Kalex Systems, Turning Waste Heat into Power

I met the CEO of a Kalex Systems recently, really neat guy with a fascinating company. The company’s technology is based on the Kalina Cycle, a method for recovering heat and converting it into mechanical power. I get excited about technologies like this because so much of the available energy at our disposal is thrown [...]

LED Lighting

I like home LED lighting but only for very specific applications, like counter lighting and for cabinets. The diffusion and color temperature of these lights is odd and they don’t get better as they warm up, like CFLs do. While this development is welcome, the chief business development guy just gave me an excuse to [...]

T.J. on Cleantech

T.J. Rodgers remains far too sane to be talking about public policy, clean tech, and energy policy.

T. J. Rodgers discusses the promise and pitfalls of the most popular alternative-energy sources (other than solar). Ethanol? Rodgers says it’s a “total waste.” However, bioengineering and genetic engineering that address the entire corn plant, rather than [...]

India’s Tata backs air-power car

This is actually a pretty promising technology. I don’t know too much about the inner workings but one factor that is key to the viability of this system is they have dramatically reduced the weight of the vehicle, which means look for it in compact offerings predominately. For the developing world this should be a [...]

Back to the Future

Last year I wrote about Bruce Crower’s 6 stroke internal combustion engine and even now I still think about how ingenious that concept is. Here’s the basic idea, a 4 stroke internal combustion engine is what you and I have in our modern automobile and it’s 4 stroke because the engine strokes each piston 4 [...]

Audi’s Blue Smoke Monster

500 horsepower, 738 ft-lbs of torque, 23 mpg. Pressure suit for driver - extra.

High Tech Energy Efficiency Incentives

Interesting, PG&E is offering financial incentives for companies who remove hardware through virtualization projects. Look for green data centers to be a big theme in 2008, there is already a number of venture investors who are targeting this trend, and more will surely follow. If the federal government gets involved, which is quite possible, it [...]

Do As I Say, Not As I Do. Part 1324.6

NYTime columnist Tom Friedman has certainly recast himself as voice and conscience of climate change while in Bali over the last couple of weeks; I wonder how this sits with his 11,000 square foot living accommodations. One more time, when the people who are telling me this is a crisis start ACTING like it’s a [...]

Global Carbon Tax

Does the idea of a global carbon tax administered by the United Nations frighten you as much as it does me? A massive tax scheme administered by an entity with zero accountability or moral authority bestowed on it by citizens. Whatever your position on climate change is, surely you cannot think that the United Nations [...]
