Global Warmists back off on prediction

GM has many chief engineers. Dr. Mohsen Shabana is chief engineer for the GM Sequel (fuel cell car) project (General Motors chief engineer: hydrogen as transportation fuel will shape the rest of the century).

You can read more about GM's fuel cells and advanced technology vehicles here.

Finally, AutoblogGreen has some interesting articles about technologies under development, including a 6-stroke cycle "steam" engine.

There are a lot of innovative projects going on around the world in the areas of energy efficiency, alternative fuels and CO2 reduction.

There is no other fuel - even speculated - that can replace petroleum due to fundamental numbers such as energy per kilogram.

We have nothing else that can match it's performance, doesn't mean it can't be replaced. It just means the cost of replacing it would be astronomical right now. Politics, however, could force that expenditure, so it would be wise to continue working on as many options as possible.

The AutoblogGreen site that I linked to above has an article about a process that makes hydrogen "by adding water to an alloy of the metals aluminum and gallium."

"Woodall says that the reaction of aluminum with water has the same energy content per unit weight of oil, about 20,000 BTUs or about 6 kWh per pound."

Hydrogen has energy content, by weight, competitive with oil. And then it must be compressed. Suddenly all advantages are lost.

What is the source of energy when water is added to alunimum and gallium alloys? We also do this with carbon rods in water. But that also does not make hydrogen energy.

Hydrogen could be manufactured and stored in large low pressure tanks. Energy stored for short term use that is useless for transportation - in essence a battery. Hydrogen is not a fuel. No viable technology exists even in theory to make it useful. So what technology with promise is GM working on? Notice how its top management - business school graduates - have thrown most all their eggs into one hydrogen basket. How many other technologies are therefore sitting stifled?

But again, its about doing more with less. Where are the programs to increase thermodynamic efficiencies in their piston engines. Or where are their programs to replace piston engines with something that is even more thermodynamically efficient? Government gives them millions of dollars in 1994 to build a hybrid? Eleven years later they still don't have a hybrid? What genius did that R&D?
