Martin Cooper asks that apart from nuclear energy ''what are the realistic options for future power supply for this country' (Letters last week).
Does he mean apart from installing tidal barrages across the Severn and Humber estuaries; recovering waste heat from power stations;
burning domestic refuse as fuel;
growing biomass (burnable) crops or oilseeds to make biodiesel, or sugar beet to make ethanol; encouraging the use of geothermal energy, groundheat-pump technology or solar panels for water heating;
or using heat and power technology or small-scale hydro-electric or wave power?
While recognising that none of these technologies by themselves will solve our looming energy crisis, a policy that puts its faith in wind power (the least reliable) and nuclear (the most dangerous) would be nothing short of barmy.
