Problem with hydrogen is that it can not be practically stored and can not be practically transported . Plus the molecules are so small hydrogen creeps through pressure vessel wall materials.

The cost , time and energy to fill pressure vessels to 3000, 4500 or 6000psi makes H2 prohibitive . That energy used to compress is lost as heat .

The pressure vessels are also large , heavy and awkward to fit into a vehicle chassis .

Producing H2 from any source is expensive . The best source of H2 is to build enough nuclear power plants to operate the nation during daytime peak . Then the surplus capacity

during off peak to produce H2 from water .

Plan B would be to use off peak steam mixed with natural gas in the presence of a catalyst to produce clean burning alcohol.

Alcohol is relatively cheap and simple to store and use at atmospheric pressure and at ambient temperature .

Today's Featured Article - New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time. She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had. Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start ... [Read Article]
