Expensive oil means viable alternative energy

The problem with hybrid cars is that they're built backwards. Instead of using the battery until it needs to be charged and then generating more electricity to recharge the battery with gasoline, they use gasoline first and only turn on the electricity while idling.
incorrect...Toyota hybrid technolgy which is the same used by others does not use any gasoline until it hits a speed of up to 40 or 45kmh in the Prius and the Camry...as well as idiling.

Expensive oil doesn't means viable alternative energy if those who are enriching themselves don't care to invest in alternative energy infrastructures.

You say that Hydrgen has a compareable energy density to methane. I always thought that it didn't, rather a barbeque tank of hydrogen would only be good for a very short drive. The CH4 combines with more O2 than H2.
No, it has comparable energy densities to gasoline(unleaded not diseal). Natural gas has the highest energy density of any plentiful hydrocarbon.
The hybrid design isn't backward. It takes advantage of two things. First is capturing alot of the energy lost from braking. The second using the very efficient electric motor rather than the low efficiencies of gasoline engines at slower speeds. Now at higher speeds, there just isn't enough energy stored in the batteries to sustain the electric motor, hence why the gas engine is used.

It doesn't have to be oil companies that invest in alternative energies. There are many other companies capable of doing research in this field.

Hydrogen. Once we can get that perfected, we won't need oil
We need oil to generate hydrogen. That's why oil companies are so in favour of hydrogen fuel cells.
Actually its natural gas, which is far more abundant. However, like I said, research is needed.

These other companies are seeing their (profit) margins shrink due to higher energy costs.

I'd imagine wind power conglomerates(like GE and Siemens) have benifited from higher energy costs. In fact, I don't know of alot of engineering firms who have been hurt by these energy prices. They are the ones who are going to innovate, no retail or the services sector which will get hurt by higher energy.

When a price of a good increases, the most direct effect is an increase of investments for the production of this good.

Natural gas is a byproduct from oil wells. Without the oil industry, there is no natural gas.

For transportation, easily explosive matters are not viable.

Explosions aren't really an issue. Propane cars have been around for a pretty long time and I've never heard of one exploding. Hydrogen tanks have been built that vent their gas as a result of violent shock or puncture rather than exploding.

For viability, these tanks have to be cheap.
and we're going to maintain millions of miles of roadway with what? Ashphalt made from corn oil? Plain old concrete?

Smaller and fewer motor vehicles require less roads.

Slipping slightly OT, but wanna read a cool editorial on that?
